The zero-day timeline just collapsed. Here’s what security leaders do next

A zero-day is not frightening because it is sophisticated. It is frightening because it is unknown. There is no patch in the moment it matters most. That single condition undermines the comfort most security programs rely on: time. In the past, attackers didn’t need zero-days because they relied on predictable failures in patching and credential…

Building an AI-powered defense-in-depth security architecture for serverless microservices

Enterprise customers face an unprecedented security landscape where sophisticated cyber threats use artificial intelligence to identify vulnerabilities, automate attacks, and evade detection at machine speed. Traditional perimeter-based security models are insufficient when adversaries can analyze millions of attack vectors in seconds and exploit zero-day vulnerabilities before patches are available. The distributed nature of serverless architectures…
