About VistoShield

Who We Are

VistoShield is built by Vistoweb, a hosting company based in Athens, Greece, operating since 2002. For over two decades we have managed hundreds of Linux servers running DirectAdmin, cPanel, Webmin, and bare-metal configurations for clients across Europe and beyond.

Server security is not an abstract concept for us. It is something we have dealt with every single day for 25+ years — blocking brute-force attacks, filtering malicious bots, managing firewall rules, and responding to threats in real time. VistoShield was born from two decades of real-world server security experience.

Why We Built VistoShield

For over a decade, CSF (ConfigServer Security & Firewall) was the de facto standard for Linux server security. It was installed on millions of servers worldwide, and we relied on it ourselves across our entire infrastructure.

When CSF was discontinued and development stopped, the Linux server community was left without a maintained, full-featured security solution. Alternatives were either too basic, too expensive, or designed for a completely different use case.

We decided to build what we wished existed: a modern, actively developed security tool that could replace CSF without requiring administrators to learn an entirely new system. VistoShield was designed from day one to feel familiar to CSF users while introducing modern capabilities like nftables support, advanced bot detection, IP reputation scoring, and native panel integrations.

Our Mission

We believe that robust server security should be accessible, affordable, and open source. Every Linux server — whether it is a single VPS or a fleet of dedicated machines — deserves enterprise-grade protection without enterprise-grade pricing.

That is why VistoShield offers a fully functional Community Edition under the GPL license at no cost. The Pro edition adds advanced features and priority support for those who need it, but the core security functionality is free and always will be.

Open Source Philosophy

Security through obscurity does not work. We believe that open source security software is inherently stronger because it can be audited, reviewed, and improved by the community. Every firewall rule, every detection algorithm, and every configuration option in the Community Edition is open for inspection.

Our code is available on GitHub. We welcome contributions, bug reports, and feature requests from the community. If you find a vulnerability, we have a responsible disclosure process and will credit contributors who help make VistoShield more secure.
