Overview

UUSEC WAF (uuWAF) is an open source, self hosted Web Application Firewall and reverse proxy that protects web applications from attacks and exploits. It combines several defence layers, a semantic analysis engine that understands SQL injection, cross site scripting, command injection and path traversal the way the target application would, machine learning anomaly detection, and runtime application self protection, so it recognises the intent behind an attack rather than relying only on signature lists, which keeps both evasion and false positives low.

UUSEC WAF sits in front of your sites as a reverse proxy: you add a protected site with its domain and upstream server, point the domain at the WAF, and every request is inspected before it reaches your application, with attacks answered by an interception page and the traffic marked with a uuWAF server header. It also brings a management console with traffic and attack dashboards, rule and rule set management, IP and geographic controls, TLS certificate handling with automatic Let's Encrypt issuance, and bot and CC attack defence. It suits teams who want to shield internal or public web applications behind a firewall they operate inside their own cloud account, rather than routing their traffic through a third party service.

Why the cloudimg image

cloudimg delivers the complete UUSEC WAF stack ready to protect traffic: the WAF engine, the reverse proxy and the management database are installed, wired together and pinned to a fixed release, so a working console and WAF are reachable within minutes of boot with no compose file to assemble. It is secure by default: UUSEC WAF ships upstream with a shared default console login, and the cloudimg image never ships that default live. On the first boot of every instance the default admin password is rotated to a unique per instance value written to a root only file, the default is proven rejected, and the database password is regenerated per instance and kept off every public interface. The firewall is proven, not assumed: at build time a protected demo site is stood up and the image is verified to pass a benign request and block an obvious injection probe with an interception page, so the WAF genuinely discriminates attack traffic from clean traffic. The pinned release never silently upgrades, the base is fully patched with unattended security upgrades enabled, and every deployment is paired with a step by step deploy guide and backed by 24/7 cloudimg support.

Common uses

  • Shield public or internal web applications from SQL injection, cross site scripting and other common exploits
  • Run a self hosted, AI powered web application firewall and reverse proxy inside your own cloud account
  • Add bot defence, CC attack protection and geographic IP controls in front of an existing site
