about

The segmented nerd is a blog about lateral security — the increasingly important practice of controlling and detecting what moves inside the perimeter. Micro-segmentation, distributed firewalling, east-west NDR, identity-aware policy, and the platforms shaping how we defend internal networks.

Posts land every two weeks. The cadence is intentional: fast enough to track a fast-moving product and threat landscape, slow enough that each post is actually worth your time. Each one aims to tie recent news (product updates, notable incidents, real threat activity) to something useful you could actually do this sprint.

Who this is for

Security and network engineers — the people configuring distributed firewalls, writing segmentation policy, and triaging NDR alerts. If you spend your day thinking about traffic that never touches the internet, you're the reader.
