Javascript Challenge Module

The HAProxy Javascript Challenge module prevents non-legitimate HTTP clients (suspicious browsers or computers infected by malware) to have minimal negative impact on a web application.

Javascript Challenge sends mathematical tests to suspicious clients to help distinguish between a real user and an automated bot. It also provides efficient protection for web applications against DDoS (denial of service) attacks.

Documentation

Verify Crawler

Verify Crawler checks the authenticity of any client that claims to be a web crawler and lets you enforce response policies against those it categorizes as phony. The verification is performed in the background so that legitimate web crawlers are not blocked.

Documentation

Fingerprint Module

The Fingerprinting module can identify client requests or bots even when they attempt to modify their user-agent string or through other methods.

It efficiently distinguishes real search engines from DDoS bots emulating search engines.

Documentation

WAF Offloader Module

The HAProxy WAF Offloader module can identify and block requests that attempt XSS or SQL injection attacks on applications running behind HAPEE. It comes with a customized list of fingerprints to detect false-positives while still providing effective protection for your applications.

Documentation

Advanced WAF Module

The HAProxy Technologies Advanced WAF module is designed to provide a high level of security to websites. It is a whitelist-based WAF with an extensive and restrictive blacklist, on top of which it applies legitimate and application-specific whitelist patterns.

Documentation

ModSecurity

The ModSecurity WAF module is designed to provide support for the ModSecurity 3.0 rule set format. Known as the "Swiss Army Knife" of WAFs, it enables web application defenders to gain visibility into HTTP(S) traffic and provides a powerful rules language to implement advanced protection. It is a blacklist-based WAF and easily integrates with the OWASP ModSecurity Core Rule Set.

Documentation

For cases where a bot can execute JavaScript, HAProxy Enterprise offers a Lua module that requires the visitor to solve a reCaptcha challenge in order to proceed.
