Security Signal: The Perimeter Problem

Vulnerabilities are changing rapidly, and as companies move beyond perimeter-based models to identity-first frameworks, CISOs need to ensure visibility and control across distributed systems. In a world of cloud computing and remote work, how are organizations adapting to this shift, and how far along are they on the journey to a more modern, effective security posture?

To explore the nuances of this "perimeter problem," this episode of Security Signal welcomes Menny Barzilay, CEO and Co-founder of Milestone, and Steve Pascucci, Head of Zero Trust for Cloudflare.

The conversation covers the reality of implementing Zero Trust, offers practical, real-world advice on where to begin, from creating an inventory of applications to securing remote access, and discusses the outsized impact of automating processes. Looking ahead, they also confront the next wave of threats, including the rise of autonomous AI-driven hacking systems that will reshape the defense landscape entirely.
