Pyxsoft Firewall — The Next-Generation Firewall for cPanel & WHM

· 4 min read

“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.


🧑‍💻 Join the Beta Program

We’re opening a 2–3 week private beta to test the upcoming release with real users — hosting providers, sysadmins, and security enthusiasts who want to help shape the future of server protection.

As a beta tester, you’ll:

  • Get early access to Pyxsoft Firewall
  • Collaborate directly with our engineers in a private Slack group
  • Share real-world feedback and influence the roadmap
  • Be featured as an Official Beta Contributor after the program

🕐 The beta will run for a limited time, with a small group of selected participants.
💬 After acceptance, you’ll receive installation instructions and your Slack invite.

🧠 Why this matters

When a cornerstone tool like CSF disappears, the gap it leaves is not just technical — it’s emotional.
Every admin who ever typed csf -r knows that mix of comfort and control it brought.

Pyxsoft Firewall honors that legacy while embracing the technologies and challenges of the next decade:
from nftables to declarative rule management, from static configuration files to API-driven automation.

We believe a firewall should be transparent, predictable, and powerful — not a black box.
That’s the philosophy behind Pyxsoft Firewall.


🌍 The bigger picture

Pyxsoft Firewall is part of a growing ecosystem that includes:

  • Pyxsoft Anti-Malware — real-time scanning and AI-assisted analysis
  • Pyxsoft WAF — intelligent web application protection and metrics dashboards
  • Pyxsoft Security Suite — unified visibility, policies, and automation across your servers

Together, these tools create a seamless security layer for cPanel/WHM environments — all managed from one unified platform.


🧭 Looking ahead

Over the coming weeks, our focus will be on fine-tuning performance, expanding nftables compatibility, and polishing the WHM interface for the official public release.
The insights from our beta testers will be invaluable in achieving that goal.

If you’ve ever relied on CSF, or simply care about robust server security, this is your chance to help define its successor.
