This can reduce false positives by up to 60%.Preemptive security strategies are more cost-effective than reactive measures. If security programs are implemented properly, they can potentially reduce the cost of a breach by up to 50%.There are more sophisticated cyber threats facing the finance industry than ever before. Every day, banking systems have to fend off thousands of attacks. These attacks are targeting sensitive financial data, customer information, and transaction processing systems. As cyber criminals evolve their tactics, financial institutions need to shift from reactive security approaches to preemptive strategies. These strategies anticipate and neutralize threats before they materialize. Superior Press is a leader in treasury management solutions. They have been working with financial institutions to strengthen their security postures. They use innovative technologies and best practices to do this.
During 2023, financial service companies suffered an average cost of $5.9 million for each data breach. This amount is significantly higher than the global average across all industries. The need to protect financial assets and maintain customer trust has never been more critical.
In a Nutshell: Staying Ahead of the Game in Financial Security
Being proactive about security means finding potential threats and weaknesses before they can be used against you. Instead of waiting for an attack to happen and then dealing with it, financial institutions need to constantly monitor their environments, assess threat intelligence, and put controls in place that stop attacks from working. This approach needs a deep understanding of both the threat landscape and your organization’s particular risk profile.
Why Cybercriminals Often Target Financial Institutions
Financial institutions are attractive targets for cybercriminals for three main reasons: the potential for immediate financial gain through theft, access to a large amount of sensitive customer data, and the possibility of disrupting crucial financial infrastructure. The concentration of valuable assets makes banks, investment firms, and insurance companies especially appealing to advanced threat actors, from financially motivated criminals to nation-state groups.
The Increasingly Dangerous Threat Landscape in 2024
Financial institutions are dealing with a threat landscape that is becoming more and more complicated. In 2023, there was a 37% increase in ransomware attacks on financial services, and ransomware-as-a-service has made it easier for criminals with less technical skills to launch sophisticated attacks. At the same time, supply chain attacks are on the rise, with attackers compromising trusted vendors to gain access to financial networks. What is perhaps most alarming is the rise of AI-powered attacks that can adapt to defensive measures and mimic legitimate user behavior with an accuracy that we have never seen before.
Not only are simple phishing emails a part of social engineering, but more complex methods such as voice phishing (vishing) and SMS phishing (smishing) are being used to target employees and customers in the financial sector. The perpetrators of these attacks use real-time data from social media and data breaches to make their scams seem more believable.
The True Price of Security Lapses in Finance
Security breaches in the finance industry cost more than just the immediate financial loss. Industry studies have shown that the average cost of a data breach in financial services is made up of several elements that add up over time:
The Real Price of Security Breaches in the Finance Sector
Direct monetary losses: $2.1 million (average)
Regulatory penalties: $0.8-3.2 million (depending on jurisdiction)
Legal costs: $0.9 million (average)
Customer notification and response: $0.5 million
Brand damage and loss of customers: $1.5 million (minimum estimate)
Operational disruption: $0.7 million (average per day of downtime)
Source: 2023 Report by the Financial Services Information Sharing and Analysis Center (FS-ISAC) On top of these measurable costs, banks and other financial institutions can suffer lasting reputational harm that can undermine customer confidence and hinder business expansion for years after a major security breach. In a sector that relies on trust, security breaches can have especially damaging effects on customer retention and acquisition.
Moving from a Reactive to a Proactive Security Stance
Old-school security practices leaned heavily on perimeter defenses and reacting to incidents once they were detected. The current threat environment calls for a basic shift to proactive security that anticipates threats before they become reality. This change in thinking involves constant monitoring, threat hunting, and intelligence-driven security operations that can identify possible threats before they have an effect on key systems.
When it comes to security, being proactive can make a huge difference. Not only can it prevent breaches from happening in the first place, but it can also lessen the damage when they do happen. In fact, organizations that have a mature proactive security program have 53% fewer successful attacks and can contain incidents 28% faster than those who are mostly reactive. The return on investment is also quite impressive. For every dollar that financial institutions invest in proactive security measures, they save an average of $2.80 in costs related to breaches.
1. Adopt a Zero-Trust Framework
The Zero-Trust framework is a significant change in the security mindset. Instead of assuming that everyone within the network perimeter is trustworthy, Zero-Trust operates on the principle of “never trust, always verify.” This is especially important for financial institutions where high-value transactions and sensitive data processing are constantly taking place across distributed environments.
Moving Past Conventional Boundary Protections
Conventional network security models create a robust exterior with a comparatively trusted interior, akin to a castle with sturdy walls but limited internal security. Zero-trust architecture eradicates this concept. Instead, it authenticates every user and device attempting to access resources, no matter their location. This method is especially useful for financial institutions with intricate environments that span on-premises infrastructure, various cloud services, and remote workforce access points.
Essential Elements of Zero-Trust for Financial Networks
For financial networks, applying zero-trust requires several key elements to work together. Micro-segmentation breaks your network down into secure areas to contain breaches and restrict lateral movement – this is especially crucial for keeping payment processing systems separate from general corporate networks. All users must have strong identity verification through multi-factor authentication, with risk-based authentication providing additional verification steps for unusual access patterns or high-risk transactions. For more insights, explore top strategies to elevate cybersecurity in fintech.
Another key aspect is ongoing observation and confirmation, as zero-trust assumes that systems can be compromised at any moment. Banks and other financial institutions need to put in place real-time observation that checks the security position of devices, examines user behavior for anything out of the ordinary, and constantly confirms access privileges against established policies and risk thresholds.
Where to Start and What to Focus On
Moving towards a zero-trust architecture is not something that can be done overnight, especially for established financial institutions with complicated legacy systems. Start by figuring out what your most sensitive data and systems are – usually this is payment processing, customer PII storage, and core banking platforms. Put in place strong authentication, micro-segmentation, and continuous monitoring for these critical assets first. Then, start applying zero-trust principles to internal administrative systems and slowly expand to cover all network resources over time.
Mid-sized financial institutions typically need 12-18 months to fully implement these systems, while larger organizations may need 24-36 months. Superior Press supports financial institutions through this transition by offering secure treasury management solutions that work well with zero-trust frameworks.
2. Carry Out Regular Threat Intelligence Assessments
Financial organizations are exposed to specific threats that require specialized intelligence. Proper threat intelligence is not only about gathering data, but also about converting that data into actionable insights that are specific to the risk profile of your organization. By evaluating the patterns, tactics, and procedures employed by threat actors who target financial services, security teams can proactively reinforce defenses against the most probable attack vectors.
Where to Find Threat Intelligence for the Finance Industry
If you want to build a strong threat intelligence, you need to gather information from many different sources. There are sharing groups that focus on the finance industry, like the Financial Services Information Sharing and Analysis Center (FS-ISAC), that can give you valuable information about threats that are specifically targeting financial institutions. You can also use commercial threat feeds from vendors like Recorded Future, Digital Shadows, or FireEye to get a wider view of emerging threats and vulnerabilities.
Security blogs, social media monitoring, and dark web forums can provide open-source intelligence (OSINT) that can give you a heads up about planned attacks or compromised credentials being traded. However, the most valuable intelligence often comes from your own security logs and incident data, which reveal the specific tactics attackers are using against your organization.
Understanding and Acting on Intelligence Reports
Without the right context, raw intelligence doesn’t mean much. The goal is to turn technical indicators and warnings into actionable security enhancements. If you receive intelligence about a new malware variant that’s targeting financial institutions, your security team should quickly evaluate your current detection capabilities. Then, update your signature-based tools and use behavioral analytics to identify the unique characteristics of the malware.
When working with threat intelligence, it’s crucial to prioritize. Pay attention to threats that are aimed at your particular financial subsector (such as retail banking, investment services, or insurance), your geographic area, and your technology stack. Evaluate each threat using three criteria: the threat actor’s ability, their intention to target your organization, and your particular vulnerability to their tactics.
Using Automated Tools for Constant Surveillance
Human analysis of threat intelligence is not fast enough to keep up with the speed of today’s evolving threats. Automated platforms can take in, normalize, and correlate threat data from multiple sources, which allows for faster detection of emerging threats. SOAR (Security Orchestration, Automation and Response) platforms can automatically take defensive actions when certain threat indicators are identified, reducing response times from hours to minutes.
Human analysts might miss subtle patterns in threat data that machine learning algorithms can identify, providing early warning of coordinated campaigns targeting financial institutions. When evaluating automation tools, prioritize solutions with pre-built integrations for financial security systems and compliance reporting capabilities to streamline regulatory requirements.
3. Enhance Your Third-Party Risk Management
Third-party relationships are one of the biggest security risks for financial institutions. Everything from payment processors to cloud service providers, these external partners often have privileged access to sensitive systems and data. Studies show that 63% of financial data breaches involve third-party access, underscoring the vital importance of thorough vendor security assessment.
Third-Party Risk Management
For effective third-party risk management, a structured assessment framework is essential. A tiered approach should be developed that categorizes vendors based on their access to sensitive data, system criticality, and potential impact in the event of a compromise. Vendors that are high risk should have comprehensive security assessments, including documentation review, on-site evaluations, and penetration testing of their systems that interface with your systems.
Aside from technical controls, you should also assess your vendors’ security governance, how they handle security incidents, and how aware their employees are of security issues. You should be especially careful to understand how they manage their relationships with their own vendors, as these fourth parties can often pose a risk that is overlooked. Keep in mind that compliance certifications like SOC2 are a good start, but they don’t replace the need for a thorough assessment of each vendor.
Security Requirements in Contracts
Good security starts with precise contractual responsibilities. Make sure all vendor contracts include specific security requirements, such as encryption standards, access controls, vulnerability management, and incident response duties. State the timelines for breach notification (usually within 24-72 hours), your right to check their security methods, and well-defined remediation requirements for any vulnerabilities found.
Make sure your contracts include clauses that allow you to end the agreement if there are serious security breaches, and that make the vendor financially responsible if their negligence causes a breach. You might also want to require high-risk vendors to carry cybersecurity insurance that provides adequate coverage. These contract provisions will make sure everyone knows what is expected and will give you a way to recover some of your losses if there is a security failure.
Regular Supplier Check Methods
Assessing the security of your supplier is not a one-off task. You should be regularly checking them to identify any new risks that may have arisen during your relationship with them. You can use external scanning services to monitor your suppliers’ public-facing infrastructure for any vulnerabilities, compromised credentials, and configuration issues. Regular security questionnaires and attestations can help you to verify ongoing compliance with security requirements, while scheduled penetration tests can validate the effectiveness of controls. For insights into managing digital campaigns, explore Buffer’s global campaigns management strategies.
Consider setting up live monitoring for important third-party connections using API security gateways or dedicated third-party access management solutions. These tools can identify strange access patterns, data transfers, or configuration changes that might suggest a compromise. Keep in mind that vendor relationships often change over time, so reassessment is needed when services expand or access requirements change.
4. Implement Advanced Fraud Detection Measures
Today’s financial fraud is not as simple as forging a transaction or taking over an account. Modern fraud schemes are complex and use advanced social engineering, synthetic identities, and automated attacks that can slip past traditional rule-based detection systems. To prevent fraud, you need detection measures that are just as advanced and can adapt to these changing threats.
Using Machine Learning to Detect Anomalies
Traditional systems that use rules to detect fraud can often produce false positives or fail to detect fraud at all. Machine learning offers a solution to this problem by analyzing patterns in millions of transactions to find anomalies that might be missed by rules. Machine learning models can be trained on historical data about fraud to find known patterns using supervised learning. Unsupervised learning can be used to find previously unknown types of fraud by looking for behavior that deviates from the norm.
The best way to detect fraud is by using a variety of model types in one fraud detection system. For instance, random forest algorithms are great at finding patterns in transaction fraud, while deep learning neural networks are better at finding complicated account takeover attempts. Ensemble methods, which combine predictions from a variety of models, are usually the most accurate. They can reduce false positives by up to 60% compared to traditional rule-based systems.
Consistent Practice Scenarios
Structured practice scenarios, or tabletop exercises, allow your team to rehearse their incident response techniques without the stress of a real breach. For those in the finance industry, these practice scenarios should mimic situations that could happen in your specific environment, such as ransomware affecting your main banking systems, business email compromise that targets wire transfers, or DDoS attacks that occur at the same time as fraudulent transaction attempts. Include representatives from all necessary departments, including not just IT and security, but also legal, communications, customer service, and executive leadership.
During these exercises, make sure to record all decisions, actions, and insights. This will help you spot any areas where your response capabilities may be lacking. Many financial institutions run these exercises on a quarterly basis, with more in-depth simulations taking place once a year. The most effective exercises are those that incorporate recent threat intelligence and that evolve to address new attack vectors. Keep in mind that the aim isn’t to “win” the exercise. Instead, it’s to spot and fix weaknesses before a real incident takes place.
9. Embrace Automation and Orchestration in Security
Financial institution security teams are often swamped with alerts, regular tasks, and intricate threats. Security Orchestration, Automation and Response (SOAR) systems can revolutionize how these teams work by automating regular tasks, orchestrating complicated workflows, and allowing for quicker, more uniform responses to security incidents. Gartner states that organizations that implement SOAR can decrease the average time to respond to incidents by 86%.
Automation doesn’t take away the job of human analysts, it actually helps them to concentrate on more complicated threats that need human judgment. Automation platforms take care of routine tasks and provide alerts with contextual information, allowing security professionals to spend less time on repetitive work and more time on strategic analysis. Superior Press incorporates security automation into their treasury management solutions, assisting financial institutions in improving their security posture without adding to their operational burden.
Security Functions Ideal for Automation
Some security tasks are especially appropriate for automation. Alert triage and enrichment can be automated to gather relevant data, verify threat intelligence sources, and prioritize alerts before human analysis. Vulnerability management workflows, including scanning, prioritization based on asset value, and patch verification can be orchestrated from start to finish. User access reviews, often a time-consuming compliance requirement for financial institutions, can be mostly automated with human oversight only for exceptions and high-privilege accounts.
Choosing the Right SOAR Platform
When looking at SOAR platforms, banks and other financial institutions should look for a few key features. The platform should have pre-built integrations with your current security tools, playbooks specifically designed for the financial industry, and features for compliance reporting. It should also be easy to customize, as you’ll need to adjust playbooks to fit your specific environment and meet regulatory requirements. For more insights on improving cybersecurity in fintech, you can explore strategies to elevate cybersecurity.
Try to find platforms that offer detailed role-based access controls and thorough audit logging to stay in line with financial regulations. As your automation program grows, machine learning capabilities that can enhance automated decision-making will become increasingly valuable. Lastly, make sure the platform provides strong analytics to track performance improvements and show ROI to leadership.
Working with Your Current Security Infrastructure
For SOAR implementation to work, it needs to integrate well with your existing security ecosystem. Begin by pinpointing all systems that the SOAR platform will feed into or receive output from. This includes SIEMs, threat intelligence platforms, ticketing systems, and communication tools. Develop an integration approach that is phased, starting with use cases that are high-volume and low-complexity. This will quickly show value before moving onto scenarios that are more complex. Make sure to create detailed documentation of all integrations. This should include API connections, authentication methods, and data flows. This will make troubleshooting and future enhancements easier.
10. Create a Framework for Cyber Resilience
For financial institutions, cyber resilience is more than just traditional security. It’s about ensuring the business can continue to operate, even when a cyber attack is successful. This means that critical functions like account access and payment processing can continue during and after a security incident. A good cyber resilience framework will address technical controls, but also people, processes, and the interdependencies between different systems and business units. This is a recognition that it’s impossible to prevent every attack, so the ability to recover from an attack is just as important as the ability to defend against one.
Keeping Digital Services Running
Today’s financial institutions depend a lot on digital services. This makes it crucial to keep these services running during security incidents. Your business continuity planning should identify the longest downtime you can afford for each service. This should be based on how much the downtime would impact your business and what your customers need. For critical services like processing payments or online banking, this could be measured in minutes instead of hours.
The most resilient organizations develop multiple processing pathways for critical functions. For example, if your primary payment processing system is compromised, can transactions be routed through alternate channels or partner institutions? These alternate pathways should be established and tested before they’re needed in an actual incident. For insights on how technology can enhance operational resilience, explore blockchain development tips and tricks that can be applied to secure financial transactions.
Regularly perform dependency mapping to spot and resolve any single points of failure in your digital service ecosystem. Often, this process will uncover surprising dependencies on shared infrastructure, third-party services, or key personnel that could affect multiple systems at once in the event of an incident.
Securing Your Financial Data: Backup and Recovery
Financial data requires a unique approach to backup that balances the need for access with the need for security. The 3-2-1 backup strategy is a good starting point: have at least three copies of your data, store the backups on two different types of media, and keep one copy offsite or disconnected from your primary network. For transaction data and customer records, you might want to consider more frequent backups with the ability to recover data from a specific point in time to reduce data loss. Critical systems might require continuous replication to a standby environment that can be brought online within minutes of a primary system failure.
Thinking About Cyber Insurance
These days, cyber insurance is a must-have when it comes to planning for financial resilience. However, not all policies offer the same coverage. When you’re looking at cyber insurance, make sure it covers regulatory fines, the cost of notifying customers, business interruptions, and payments for cyber extortion, if it’s legal. It’s also important to know what’s not covered, especially when it comes to social engineering attacks, acts of war, or not meeting minimum security standards. The best way to approach insurance is to see it as one part of a larger risk transfer strategy that includes contract protections with vendors and the right reserves for self-insured risks.
Assessing the Impact of Your Security Measures
Many leaders in financial security struggle to prove the success of their security investments. To move past basic measurements such as “number of attacks prevented,” leaders must use a strategic approach to measurement that relates security actions to business results. Successful measurement blends leading indicators, which forecast future security performance, with lagging indicators, which confirm past effectiveness. The aim is to show that your security measures have both reduced risk and enabled business.
Performance Indicators for Security in Finance
Create a scorecard of security metrics that can be understood by different individuals in your organization. For technical teams, focus on operational metrics such as mean time to detect (MTTD) and mean time to respond (MTTR) to security incidents, vulnerability remediation timelines, and coverage metrics for security controls. For business leaders, translate these technical metrics into business impact measures such as reduced fraud losses, improved customer trust scores, and decreased compliance findings.
By showing how security activities decrease the likelihood and potential impact of incidents, risk reduction metrics provide a valuable tool. It is important to track metrics like the percentage of critical assets covered by advanced security controls, the reduction in high-risk vulnerabilities over time, and improvements in phishing simulation results. Rather than absolute values, these metrics should show trends over time to demonstrate continuous improvement.
Security is more than just a cost of doing business, it can be a competitive advantage. By tracking how security measures positively impact business goals, such as reducing friction in the customer authentication process, minimizing false positives in fraud detection systems, and speeding up the deployment of secure applications, financial institutions can demonstrate the value of their security investments. In addition, tracking metrics such as customer retention among security-conscious client segments and new business opportunities enabled by strong security posture can provide a competitive edge.

Example dashboard based on industry benchmarks for a financial institution of medium size Security Maturity Assessment Framework
Maturity models offer a methodical way to evaluate how your security program is progressing in several areas. Banks and other financial institutions should customize frameworks such as the NIST Cybersecurity Framework or FFIEC Cybersecurity Assessment Tool to fit their unique situation. These frameworks generally measure maturity in areas like governance, risk management, threat intelligence, defensive technologies, and incident response capabilities.
Each year, make sure to carry out thorough maturity assessments, and every three months, review any areas that need to be bettered. The assessment should include stakeholders from all areas of the organization and also include external perspectives from assessors who are familiar with key changes to the financial industry. The aim isn’t to reach the highest maturity level in all areas, but to match security investments with your particular risk profile and business objectives.
Communicating Security ROI to Upper Management
When security leaders speak with executives, they need to use business language instead of technical jargon. They should explain how investments in security can protect revenue, lower costs, create business opportunities, and help manage compliance responsibilities. Security ROI can be quantified using metrics such as decreased fraud losses, avoided regulatory fines, lower incident response costs, and infrastructure savings due to security tool consolidation. When presenting to boards and executive committees, use benchmark data to compare your security posture to that of your peers in the industry and link security initiatives directly to strategic business goals and risk appetite statements.
Common Questions
Financial security leaders often ask these questions when they are putting preemptive security strategies into action. The answers given here offer a broad overview and should be tailored to fit your specific regulatory environment and risk profile.
The world of financial security is constantly changing, with new dangers and protective technologies popping up all the time. When putting these suggestions into action, seek advice from security experts who are familiar with your specific area of the finance industry.
What is the typical cybersecurity budget for a financial institution?
Most financial institutions will dedicate between 6-15% of their total IT budget to cybersecurity. This percentage often increases as the organization grows in size and complexity. However, it’s important to base your budget allocation on risk rather than industry averages. Conduct a thorough risk assessment to identify your biggest threats and vulnerabilities, then allocate your resources based on that. High-risk areas like payment processing systems and customer data storage usually require a larger security investment than lower-risk operations. Keep in mind that effective security requires not just investment in technology, but also sufficient staffing, training, and third-party services.
Which compliance standards are most important for financial security?
PCI DSS for organizations that handle payment card dataSOX requirements for publicly traded financial institutionsGLBA/FFIEC guidelines for protecting customer dataGDPR, CCPA, and other privacy regulations depending on the customer’s locationIndustry-specific frameworks like the SWIFT Customer Security Program for international bankingWhile compliance is necessary, it only represents a minimum baseline and not comprehensive security. The most effective strategy maps regulatory requirements to a broader security framework like NIST CSF or ISO 27001 to ensure both compliance and security objectives are efficiently met.
Keep a record of your compliance mapping to show how security controls meet several regulatory requirements at once. This method can make audits and assessments more efficient while guaranteeing that controls are implemented consistently throughout the company.
Many banks and finance companies have dedicated governance committees to oversee both security and compliance activities. This is to ensure that there is a balance between these two often-related functions. It also prevents situations where compliance activities might accidentally conflict with security best practices.
Think about hiring compliance experts who specialize in complicated regulatory environments. This is especially important for multinational financial institutions that are subject to regulations in multiple jurisdictions. These experts can help you navigate conflicting requirements and make your compliance program as effective as possible. For more insights, explore these top 10 strategies to elevate cybersecurity in fintech.
How frequently should we revise our security strategies?
At least once a year, you should formally review your financial security strategies. However, you should also make adjustments every quarter based on new threats and changes in your business environment. If there are major changes in your business—like mergers, the launch of new products, or significant technology implementations—you should review your strategy immediately, regardless of the regular schedule. You should also set up a dedicated threat intelligence function to continuously monitor for emerging risks that might require strategic adjustments between formal reviews.
Write down your security plan across different time frames: a three-year strategic roadmap, yearly tactical plans, and quarterly implementation priorities. This multi-layered approach combines long-term capability development with the flexibility to respond to new threats. Include business stakeholders in strategy reviews to ensure that security initiatives continue to align with changing business goals and risk tolerance.
Keep in mind that updating your strategy effectively requires a truthful evaluation of your current abilities and gaps. Consider periodically bringing in external assessors to give an unbiased evaluation of how effective your security program is in relation to current threats and industry standards.
What should be the priority security measures for mobile banking?
Mobile banking has unique security challenges due to the mix of sensitive financial functions, uncontrolled device environments, and diverse connectivity options. Prioritize application security by using strict secure development practices, regular penetration testing, and runtime application self-protection (RASP) technologies that can detect and respond to attacks in real-time. Implement risk-based authentication that adjusts security requirements based on transaction risk, user behavior patterns, and device health indicators rather than applying the same authentication requirements to all activities.
It is crucial to verify the security of devices used in mobile banking settings. Include the ability to identify devices that have been jailbroken or rooted, those with malware, and those running outdated operating systems that may have security flaws. Rather than completely denying access, you might want to consider limiting the capabilities of devices that pose a higher risk. This approach balances security with customer experience. For instance, devices that pose security risks might only be allowed to check balances and not be allowed to make transfers that exceed certain limits.
Securing your data means going beyond just the app and into the entire mobile ecosystem. You can use certificate pinning to stop man-in-the-middle attacks, make sure all your data is encrypted whether it’s in transit or at rest, and use secure enclaves or trusted execution environments for cryptographic operations when you can. You might also want to think about putting remote data wipe capabilities in place so you can get rid of sensitive information if a device is reported as lost or stolen.
How can smaller financial institutions implement these strategies with limited resources?
Smaller financial institutions can implement effective security programs despite resource constraints by focusing on risk prioritization, leveraging managed services, and adopting cloud-based security tools with consumption-based pricing models. Start by conducting a thorough risk assessment to identify your most critical assets and threats, then allocate your limited resources to these high-priority areas rather than attempting to implement comprehensive controls everywhere simultaneously. Consider joining financial services information sharing organizations like FS-ISAC, which provide threat intelligence and best practices specifically for financial institutions of all sizes.
Managed security service providers (MSSPs) offer a cost-effective solution for smaller institutions by sharing their specialized security expertise with multiple clients. When choosing a provider, it’s important to find one with experience in the financial services industry and knowledge of the compliance requirements that are relevant to your organization. Many MSSPs offer customized service packages for community banks and credit unions that include round-the-clock monitoring, vulnerability management, and compliance reporting for a fixed monthly fee.
Cloud-based security tools can help to cut costs and administrative work while offering advanced features that were previously only available to larger organisations. Solutions such as cloud-based SIEM platforms, email security services, and identity management systems offer advanced features without the need for extensive on-site infrastructure. Many vendors offer pricing tiers that are specifically designed for smaller financial institutions with lower transaction volumes or user counts.
