In this episode of Talos Takes, David Bianco from Cisco Foundation AI joins Amy to demystify the world of proactive cyber defense. We explore the evolution of the PEAK Threat Hunting framework and talk through how security teams can modernize their approach to identifying risks before they escalate. David also provides an exclusive look at a new open-source tool designed to help hunters navigate the "prepare" phase of PEAK with ease. 

Whether you are building a new program from scratch or looking to refine your existing strategy, take a listen for actionable advice to help you take that next step in your security journey.

Service providers are the backbone of modern connectivity — but why are they such attractive targets for cyber actors, and what happens when critical networks go down? In this episode, Martin Lee joins Amy to explore the shifting threat landscape for service providers, asking how defenders can spot silent intrusions, what trade-offs must be considered when patching, and how industry collaboration helps prevent widespread disruptions. Join us as we unpack real-world examples and offer practical insights into protecting the infrastructure that keeps our world connected.

What separates organizations that successfully fend off ransomware from those that don’t? What were the top threats facing organizations? Can we (pretty please) get a sneak peek into the 2025 Year in Review?

Amy is joined by Dave Liebenberg, Strategic Analysis Team Lead, to break down key findings from Q4 2025's Cisco Talos Incident Response Quarterly Trends Report. From the top threats facing organizations — like the persistent exploitation of public-facing applications and the rise of new vulnerabilities such as Oracle EBS and React2Shell — to the unexpected drop in ransomware cases, this episode is packed with useful info.

Step into the fascinating world of cryptography. Host Amy Ciminnisi sits down with Yuri Kramarz from Cisco Talos Incident Response and Tim Wadhwa-Brown from Cisco Customer Experience to learn what encryption really accomplishes, where it leaves gaps, and when defenders need to take proactive measures.

Whether you’re picturing classic codebreakers or the latest quantum-proof ciphers, this episode unpacks the essentials: what encryption and hashing actually mean, why key management is a make-or-break factor, and how even the best algorithms can fall short if the basics aren’t handled right.

Get ready for a brand-new era of Talos Takes! In the first episode of the year, Amy Ciminnisi, Talos’ Content Manager and new podcast host, steps up to the mic with Joe Marshall to explore certifications, one of cybersecurity’s overwhelming (and sometimes most controversial) topics. We dive into the world of vendor-specific and vendor-agnostic certs, the value they can bring to your career, and the barriers people often face to getting certified.

Whether you’re a newcomer facing the sea of choices and feeling some analysis paralysis or a seasoned pro plotting your next move, this episode may just motivate you to tackle your next certification with confidence.

In this special, end-of-year episode (and Hazel’s final show as host) Talos Takes goes on a time-travel adventure: What would a defender from 2015 think of the cybersecurity realities of 2025? Joined by Talos teammates Pierre Cadieux, Alex Ryan, and Joe Marshall, we compare the threats, tools, and challenges of 2015 with those of 2025. 

The team recalls where they were in their careers a decade ago, then dives deep into how ransomware has evolved, how APTs and state sponsored attacks have shifted, and why identity has become the new battleground for attackers and defenders alike. They discuss the impact of AI on both sides of the security equation, share what they miss from “the good old days,” of 2015, and offer practical advice for defenders facing the challenges of 2026 and beyond.

What happens when your to-do list keeps growing but your budget doesn’t? Hazel is joined by three Cisco Talos Incident Response experts to talk about the reality many organizations face: rising threats, aging infrastructure, and fewer people to defend it all.

From configuring what you already have, to open-source strategies, to the impact of cybersecurity layoffs, this episode is packed with practical guidance for securing your organization during an economic downturn.

In this episode of Talos Takes Hazel sits down with Talos' Bill Largent and Craig Jackson to discuss the latest Cisco Talos Incident Response Quarterly Trends Report (Q3 2025). From a wave of Toolshell events, to a rise in post-exploitation phishing, and the misuse of legitimate tools like Velociraptor, this quarter’s cases all point to a theme: attackers are getting very good at living off what’s already in your environment.

On this episode of Talos Takes, Hazel welcomes Cisco Duo experts Steven Leung and Tess Mishoe to bust the most common myths around passwordless security and multi-factor authentication (MFA). Discover why not all MFA is created equal, why passwordless doesn't mean less security, and the most seamless way to adopt passwordless solutions. Plus, learn the truth about how passwordless may affect compliance and audits, and whether passwordless really is more vulnerable to phishing. 

Every October, Cybersecurity Awareness Month brings a wave of tips: update your software, enable MFA, use strong passwords. But what good is any of that if the people behind the defenses are feeling burned out?

In this episode of Talos Takes, Hazel sits down with Joe Marshall for a candid, vulnerable conversation about the human cost of cybersecurity. Joe opens up about his experience during the VPNFilter campaign — months of secrecy, long hours, immense pressure, and the trauma it left behind. Hazel shares her own journey with burnout, and together they talk about how to recognise the warning signs.

They close with practical steps: building a personal “incident response playbook” that includes boundaries, peer support, and self-care. Because at the end of the day, you can’t patch a system if you're burned out.
