In 2000 the internet was expanding at an astronomical rate. Consumers were logging in via dial-up modems by the hundreds of millions and businesses were racing to maximize their footprint in the digital world. A hacker named Onel de Guzman living in the Philippines had been playing with a script called “I Love You”. Distributed via email, it could assume secret control of an individual's computer from a centralized control. The “I Love You” virus spread to over 50 million computers, creating the world's largest botnet. Michael Tiffany and his co-founders were aware of these types of cyber attacks and wanted to ensure the Internet worked for businesses wanting to connect with consumers. They founded Human Security, one of the first companies to combat botnet activity for major brands and today a very powerful cybersecurity company for major corporations.

In this episode of Secure Talk, host Justin Beals interviews Michael Tiffany, co-founder of Human Security and the current leader of Fulcra Dynamics. Michael shares his early experiences with computers and his journey into cybersecurity, discussing topics the founding of Human Security as a solution for botnets, ad fraud, and early “Know Your Customer” challenges. He explains his current company, Fulcra's mission to empower individuals by unifying their personal data and promoting privacy and control in the age of AI.

Eldon Spickerhoff founded eSentire in 2001. He had been a Senior Information Security Engineer for ING Prime after completing his academic work at Waterloo University. At the time the cybersecurity solutions marketplace was primarily a services offering, focusing on vulnerability scanning. The team at eSentire realized that the tools deployed in vulnerability scanning to internal systems could be left running post a services engagement. And in the process they invented an ‘always on’ threat intelligence solution. In 2022 eSentire added storied private equity firm Warburg-Pincus to their cap table and achieved unicorn status with a valuation of one billion dollars.

In this engaging episode of SecureTalk, host Justin Beals invites Eldon Sprickerhoff, a seasoned cybersecurity expert and founder of eSentire, to share his journey. Eldon graduated with a computer science degree from Waterloo University in 1991 and went on to establish a leading managed security services provider.

During the conversation, Eldon reflects on his early career concerns and the macroeconomic challenges he faced during a recession. He also shares insights from his book, *Committed*, which explores the realities of startup life. The discussion highlights essential strategies for navigating the cybersecurity marketplace, the importance of founder-led sales, and the significant challenges and opportunities within the cybersecurity field.

Tune in to gain valuable perspectives on entrepreneurship, real-time vulnerability scans, and the impact of AI and quantum computing on cybersecurity.

In this episode of Secure Talk, Justin welcomes Stephen Ferrell, a cybersecurity expert and Chief Strategy Officer of Strike Graph, to discuss the significant changes in the compliance landscape brought about by the Cybersecurity Maturity Model Certification (CMMC). They explore the recent finalization of the CMMC rule, its implications for the defense industrial base, and the phased compliance requirements for various certification levels. 

The conversation emphasizes the necessity of CMMC for federal contractors, including those in non-traditional sectors like medical equipment manufacturing, along with the associated costs and procedures. Stephen also shares insights from his experience conducting a self-assessment for CMMC compliance, offering practical advice for organizations aiming to achieve certification. 

This episode is essential for cybersecurity professionals who want to understand the latest federal compliance standards and prepare their organizations accordingly.

Privacy laws in our modern computing era have been around for well over twenty years. The conversation around appropriate privacy measures and effective governance of data has matured quite nicely since the early days of the Internet. While breaches do continue to happen, laws like GDPR, HIPAA and CCPA have helped set expectations for ethical and effective privacy practices.

But we are in the midst of a massive proliferation of generative AI models. Since the technology is so nascent our expectations of privacy are being reshaped. An AI model is fundamentally a mathematical representation of a large data set. Its probabilistic function will create information depending on the prompts it can be given. Deep in the model the data used to ‘train’ it still leaves a fingerprint of the source information. What are the expectations for privacy, copyright and safety to those of us that have shared information on the internet?

In this episode of Secure Talk, host Justin Beals engages in a comprehensive discussion with Dan Clarke,  about the significant impact of AI. The conversation begins with Dan’s early days in computing and follows his journey into developing AI governance. They explore the transformative effects of AI in comparison to historical technological innovations, as well as the risks and biases that are inherent in AI systems. Additionally, they discuss current and future legal compliance issues.

Dan shares personal anecdotes related to privacy challenges and the applicability of AI, emphasizing the importance of transparency, thorough risk assessment, and bias testing in AI implementations. This episode provides valuable insights for anyone interested in the ethical and responsible use of AI technology in today's applications.
