Zenarmor

In the Army, we had “Layered Defense.” Zenarmor is your application-layer defense for your network.

Description

Zenarmor is an enterprise-grade, software-defined firewall that can be deployed on any network. It specializes in application-layer filtering, allowing you to block specific apps or websites (e.g., social media, ads, trackers) with ease.

It’s most commonly used with OPNsense in home labs to add an extra layer of visibility and control.

Knowledge Check

• Have you configured your policies correctly for your LAN and DMZ?
• Are you using any of the “Free Edition” features, or have you upgraded to “Home” or “Business”?

Common Pitfalls

• Resource Usage: Application-layer filtering requires deep packet inspection (DPI), which can be CPU intensive.
• Breaking Apps: Be careful with “aggressive” filtering policies as they can break legitimate apps.
