Microsegmentation Fails Quietly When Policy Drifts

The first policy is only a snapshot. Containment depends on keeping it aligned with the environment.

Microsegmentation policy can decay as applications, workloads, identities, and exceptions change. This article explains how to detect policy drift, govern exceptions, and continuously prove that lateral movement paths remain closed.

The AI Agent Was New. The Trust Failures Were Not.

A 17,600-action intrusion turned one dataset worker into a path toward cluster, cloud, mesh VPN, and source-control access

The July 2026 OpenAI and Hugging Face incident was powered by an autonomous AI agent, but its blast radius came from familiar trust failures. This analysis shows where microsegmentation and workload isolation could have broken the chain.

Backup Infrastructure Needs Its Own Containment Boundary

A recovery copy is not resilient when production identities and network paths can still reach it

Ransomware operators target backup systems because destroying recovery increases leverage. This article explains how to isolate backup infrastructure, separate its identity plane, constrain management paths, and test recovery as a Zero Trust boundary.

AI Data Pipelines Need Containment

When untrusted data can execute code, the processing worker becomes an attack bridge

The July 2026 Hugging Face incident shows how a malicious dataset can become code execution, credential theft, and cross-cluster lateral movement. The answer is not only safer parsing. It is a smaller blast radius by design.

Your Identity Provider Needs a Containment Boundary

When the signing key is the credential, MFA is no longer the control

Mandiant's new AD FS research shows why federation servers belong inside a Tier 0 containment boundary, with tightly governed management paths, explicit dependencies, and an incident plan built around signing-key compromise.
