Data breaches don’t just happen—they accumulate. And in today’s hyper-connected digital ecosystem, your biggest risk might not be your internal systems, but the sheer number of vendors and partners you rely on.

If you’ve ever asked yourself, “How many third parties is too many?”, then mark your calendar for June 20, 2025.

Register here for the ISACA San Diego Webinar
Date & Time: June 20, 2025 | 9:00 AM PDT
Speaker: Dr. Thomas Lee, PhD, CEO of VivoSecurity

What’s It About?

Dr. Thomas Lee—co-author of How to Calculate the Probability of a Third-Party Data Breach—is redefining how we think about Third-Party Risk Management (TPRM). His model uses probability theory to quantify third-party breach likelihood based on vendor count and data exposure levels.

Instead of guesswork or overreliance on checklists, Dr. Lee brings a mathematical model that empowers organizations to:

Understand how often breaches are likely to occur—not just if.

Strategically limit vendor data exposure based on risk thresholds.

Communicate risk to leadership in terms they understand (like “once every 5 years”).

Why Attend?

Whether you’re a CISO, risk manager, or cybersecurity analyst, this webinar will equip you with a practical, scalable, and data-driven framework to better manage one of the most misunderstood and systemic cybersecurity threats today: third-party data breaches.

Plus, it’s not just for techies. If you’re a business leader, auditor, or compliance professional who needs to justify security investments or vendor management policies, this is your playbook.
