Listen Later

Episode Summary

Recorded live at HOU.SEC.CON, The Professional CISO Show welcomes Tommy Perniciaro, Director of Solutions Architecture at LayerX, to explore why the browser has become the least-instrumented layer in the modern security stack — and how CISOs can finally gain visibility and control over it.

 

David and Tommy discuss everything from malicious browser extensions and OAuth-based phishing to AI prompt leakage and the emergence of “AI browsers.” Listeners will walk away with a new appreciation for the browser as the enforcement point of the future — and practical insights on deploying LayerX to close this growing gap.

 

Key Takeaways

  • The browser is now a primary attack surface for enterprise users.
  • LayerX gives security teams visibility and control without replacing browsers.
  • GenAI tools and prompts can leak sensitive data if not monitored at the DOM level.
  • OAuth-based phishing is bypassing traditional email and network defenses.
  • Secure enterprise browsers struggle with user adoption — LayerX works inside the browsers you already have.
  • AI browsers are emerging as the next battleground for identity and data protection.
  • Post-quantum cryptography will further challenge network-layer inspection.

Notable Quotes

“Without visibility at the DOM level, you’re flying blind to what extensions, prompts, and identities are doing inside your environment.” – David Malicoat
