NetDefense is central management for OPNsense firewall fleets. A lightweight agent (NDAgent) runs on each firewall and connects outbound only โ no listening ports, no VPN tunnel needed for management โ and every command it accepts is Ed25519-signed by the control plane rather than relying on TLS alone as the trust boundary.
Operators run the fleet from NDCLI, an open-source command-line tool that also acts as an MCP server, so Claude, GPT, or other MCP-compatible agents can audit configurations, flag anomalies, and run fleet-wide tasks in natural language. There's also a web dashboard (NDWeb) for point-and-click management.
Features include reusable, inheritable configuration templates applied across hundreds of devices, one-command WireGuard mesh networking between sites, scheduled backups to S3-compatible storage, and CLI/REST hooks for GitHub Actions or GitLab CI.
NDAgent and NDCLI are open source (Apache-2.0): https://github.com/netdefense-io โ the control plane is SaaS, with a free tier and an Enterprise on-premise option.
TinyWall NetDefenseTinyWall is recommended for Windows users who prefer a set-it-and-forget-it approach to firewall management.

Remove 11 and install Windows 10 ITSC IOT edition until the equivalent for 11 drops. Make Windows shut up for good with Tinywall (https://tinywall.pados.hu/) and whitelist applications as needed. - Source: Hacker News / about 3 years ago
Microsoft Defender is far better as an antivirus, and there are much better 3rd-party firewall options, even though Windows Firewall works just fine. TinyWall is a very low resource whitelist-only front end for Windows Firewall; Portmaster is a comprehensive network firewall. Source: over 3 years ago
