Services / Firewall & Perimeter Security

Firewall & Perimeter Security

A VPS or server sitting directly on the internet with no firewall in front of it is a bigger risk than most people realise. We deploy a hardened firewall — IPFire, pfSense, or OPNsense — in front of your infrastructure, so traffic is filtered and controlled before it ever reaches your services.

What's included

  • Firewall platform selection based on your setup (IPFire, pfSense, or OPNsense)
  • Deployment in front of your VPS, on-prem network, or both
  • Rule configuration: inbound/outbound filtering, port restrictions, geo-blocking where useful
  • VPN configuration for secure remote access, if needed
  • Intrusion detection and logging setup
  • Ongoing rule review as your infrastructure changes

Platforms

IPFire, pfSense, and OPNsense — all open-source, all capable of running on modest hardware or as a VM in front of your VPS.

Why it matters

Most VPS providers give you a public IP and leave the rest to you. Without a firewall in front of it, every open port is a door left ajar. A proper perimeter — not just relying on individual service configs — is one of the cheapest, highest-leverage security investments you can make.
