Security hardening is the practice of systematically reducing the ways an attacker can get into, move through, or persist in your environment.The reason this is a priority is that the gap between "deployed" and "properly configured" is where most breaches actually live. This guide covers the core principles of hardening, how it maps to compliance requirements, and how automated tooling has changed the way mature security teams operationalize it at scale.

AI finds the vulnerabilities, but exploiting them is a different problem. How Sophos Endpoint defends in the AI era, and what the public record on Mythos shows. When Mozilla shipped Firefox 150 with fixes for 271 issues identified by Anthropic’s Mythos model, the headlines focused on the count. The detail that mattered was further down: Mozilla credited only three CVEs to the model. The remaining 268 were classified as defense-in-depth, hardening, or bugs in code paths that could not be exploited.

AI just became the world's most dangerous exploit writer. Here's why Sophos Endpoint is built to stop it. AI-generated zero-days are here. Sophos Endpoint was architected to stop exploits that have never been seen before — blocking the techniques every attack must use, at the moment of execution, with no signature, no cloud lookup, and no configuration required.

A critical vulnerability in LiteLLM is turning AI infrastructure into an open vault; no login required. Tracked as CVE-2026-42208, this vulnerability allows attackers to extract API keys, cloud credentials, and provider authentication tokens without any credentials or prior access to the system. The root cause is fundamental lapse in input handling. LiteLLM’s API key validation blindly injects the Bearer token from the Authorization header into a SQL query without sanitization.

Over a decade ago, Cato Networks helped shift cybersecurity to a new frontier: a converged, cloud-native platform that combines security and networking. As a long-time security researcher, the Cato platform was a radical change, providing researchers with the rich context and end-to-end visibility we needed to identify threats faster and deliver accurate protections.
