The control plane

One system. Your entire edge.

From a quiet home lab to a multi-gigabit branch, FreeSense puts routing, security, VPN, and observability in one coherent interface.

01

Routing without limits

Multi-WAN, policy routing, VLANs, traffic shaping, CARP high availability, and a modern FreeBSD 16 network stack.

02

Defense in depth

Suricata 8 IDS/IPS, CrowdSec response, pfBlockerNG, DNS filtering, and firewall telemetry in one control plane.

03

A curated platform

A focused package catalog with capabilities, support status, resource impact, and native WebUI integration before you install.

ZFS boot environments

Upgrade boldly.
Roll back calmly.

FreeSense can snapshot the complete operating system before an upgrade—not just the configuration. If something goes wrong, choose a known-good environment from the WebUI or boot menu and get back online.
