Zero trust, SSE, NAC, firewalls, and policy enforcement.
8 guides
For a long time network security meant building a hard shell around a soft middle. You put a firewall at the edge, and anything inside the edge was trusted. Remote work, cloud services, and personal devices took that model apart.
Zero trust replaces the shell with a decision. Every request gets checked, every time, based on who is asking, what device they are on, and what they are trying to reach. These guides explain the model in plain language, then walk through the products that enforce it: SASE and SSE, network access control, next generation firewalls, and microsegmentation.
We link to real vendors throughout, because the words on the box do not always match the words in the standard, and it helps to see who sells what.

The mentorship starts with the Linux firewall and packet routing for a reason. You cannot understand a policy enforcement point until you understand what a packet is and where it goes.
