Artificial intelligence is changing cybersecurity on both sides of the battle. While defenders are adopting AI to improve detection and response, attackers are using it to discover vulnerabilities, automate exploitation, and dramatically accelerate the pace of attacks.

In this episode of Cybersecurity Today On The Weekend, host David Shipley speaks with Lionel Litty, Chief Information Security Officer at Menlo Security, about why today's security strategies must evolve as AI reshapes the threat landscape.

The conversation explores how AI is speeding up vulnerability discovery, why browser security has become a critical layer of defence, the emerging risks of AI agents operating inside browsers, and why recent NIST research suggests perfect AI guardrails may be mathematically impossible. Lionel also explains why organizations should prepare for future attacks that could spread even faster than Log4j.

In this episode:

How AI is accelerating cyberattacks Why browser isolation can reduce risk The security challenges created by AI agents Prompt injection and browser extension threats Why AI guardrails have fundamental limits Lessons from Log4j and preparing for the next major exploit Practical advice for CISOs and security leaders
