Pyxsoft Firewall — The Next-Generation Firewall for cPanel & WHM
“Every end marks a new beginning.”
With ConfigServer (CSF) officially discontinued, an entire generation of hosting administrators has suddenly lost its most trusted ally.
But security doesn’t stand still — and neither do we.

🔥 The legacy continues
For over a decade, ConfigServer Security & Firewall (CSF) was the backbone of server security for thousands of web hosts and system administrators around the world.
It was simple, robust, and deeply integrated into WHM/cPanel, becoming almost synonymous with Linux firewall management in hosting environments.
Yet technology evolved — nftables replaced iptables, automation became the norm, and cloud-native networking reshaped the landscape.
CSF’s end marks not only the close of an era but also the opportunity to build something better, modern and future-proof.
That’s where Pyxsoft Firewall comes in.
🧩 Introducing Pyxsoft Firewall
Pyxsoft Firewall is the natural successor to CSF — rebuilt from scratch with a modern architecture, designed for today’s Linux servers (RHEL 7/8/9) and tomorrow’s hosting environments.
Highlights
- 💠 Native nftables core — with automatic iptables fallback when needed
- 💻 Modern WHM interface — clean, intuitive, and mobile-friendly
- 📜 Declarative journal model — rules are predictable, versionable, and human-readable
- ⚡ Smart reloads — no downtime, no race conditions
- 🧱 Brute-force protection (LFD-style)
- 🔐 Bastion and access rules with IPv4/IPv6 support
- 🧩 Full integration with Pyxsoft Security Suite (WAF + Anti-Malware)
This is not just an update — it’s a complete redesign of what a Linux firewall should be in 2025.
