Haltdos Community WAF key features

Haltdos Community WAF is a free, self-hosted Web Application Firewall — a reverse-proxy security layer you install in front of your web applications or APIs. It inspects incoming HTTP/HTTPS traffic and blocks malicious requests (such as SQL injections, XSS, and other OWASP-Top-10 vulnerabilities), DDoS and bot attacks, giving you comprehensive web-app protection.

UI-managed WAF
Haltdos Community WAF provides a web-based management interface so you can configure, manage and monitor the WAF without needing to edit config files manually.
Built-in attack signatures
Haltdos Community WAF ships with hundreds or thousands of predefined signatures to protect against common web attacks (e.g. SQL injection, XSS, etc.), so protection works out-of-the-box.
Custom rules & user-policies
Haltdos lets you define your own rules (e.g. header rules, redirection, request patterns) to tailor protection to your specific application needs.
Bot & automated traffic mitigation
Detects and mitigates automated or malicious bot traffic, reducing risks from scrapers, brute force bots or other automated threats.
DDoS protection / rate-limiting
Haltdos Community WAF supports custom rate-limit rules and DDoS-mitigation to help prevent overwhelming traffic or volumetric attacks from impacting your application.
Geo-fencing / geo-blocking
Allows you to block or restrict traffic based on geographic origin (geo-IP), useful to limit access from certain regions or block suspicious regions globally.
Support for Web traffic & app protection
Haltdos WAF can protect both traditional web applications and APIs by inspecting not only HTML/web traffic, but also JSON/XML payloads, headers and other data formats.
Incident logging, reporting & visibility
The WAF logs access and attack incidents, provides reports and allows fine-tuning of WAF policies based on real events.
Built-in load balancing & reverse-proxy
Haltdos acts as a reverse-proxy with load-balancing, so you can distribute traffic across multiple backend servers while still protecting them via WAF.

What customers say

Crytek
After launching another successful IP — HUNT: Showdown, a competitive first-person PvP bounty hunting game with heavy PvE elements, Crytek aimed to bring this amazing game for its end-users. We needed a hosting provider that can offer us high-performance servers with great network speed, latency, and 24/7 support.
Stefan Neykov Crytek
doXray
doXray has been using HOSTKEY for the development and the operation of our software solutions. Our applications require the use of GPU processing power. We have been using HOSTKEY for several years and we are very satisfied with the way they operate. New requirements are setup fast and support follows up after the installation process to check if everything is as requested. Support during operations is reliable and fast.
