The Human Attack Surface: What Cybersecurity Can Learn from the Secret Service | Hazel Cerra

What can 25 years of protecting the President teach the cybersecurity world?

In this episode, Raghu Nandakumara sits down with Hazel Cerra, Director of Digital Security Convergence at BlackCloak and a 25-year veteran special agent of the U.S. Secret Service, to explore what protective intelligence can teach cybersecurity about defending the human attack surface.

Hazel draws on her path from investigating counterfeit and credit card fraud, to protecting President Clinton, to pioneering critical systems protection for presidential visits, sharing how she came to see the Secret Service's layered "zero fail" security model as a direct parallel to Zero Trust, and why understanding an adversary's motive, means, and opportunity is as critical in cyber as it is in physical protection.

Raghu and Hazel discuss:

• How the Secret Service evaluates and prioritizes threats using motive, means, and opportunity
• Why "zero fail" protection is the same discipline as Zero Trust security
• How cyber convergence changed physical protection, from hackable elevators to compromised cameras
• Why executives' home networks have become the new "path of least resistance" for attackers
• Balancing security with usability, without creating unnecessary friction
• How deepfakes and AI impersonation are changing verification and executive risk

Hazel closes with a practical tip for spotting a deepfake on a video call, and a reminder that as executives become as visible as presidents once were, protecting them has to extend far beyond the corporate perimeter.
