Your Microsegmentation Policy Is Not Proven Until You Test The Deny

A clean rule set is not evidence that lateral movement paths are closed

Microsegmentation only reduces blast radius when denied paths are tested from real workloads. This article presents a practical method for validating policy enforcement, identity context, failure behavior, and containment over time.

When The Network Infrastructure Lies

Fire Ant shows why routers, TACACS, and telemetry systems need separate containment and evidence paths

Sygnia's Fire Ant investigation shows how compromised routers and authentication infrastructure can provide reach, steal credentials, and suppress the evidence defenders rely on. This article turns the incident into a practical microsegmentation and forensic-readiness design.
