Rate limiting is native, built on a feature called stick tables. You choose a key to track by, such as client IP, URL, or a custom value, then set thresholds that trigger actions like delaying or denying requests once a client crosses them. It is commonly used to stop brute-force attempts, abusive scrapers, and sudden traffic spikes, all in the load balancer configuration with no external dependency. In HAProxy Enterprise, this extends to global rate limiting coordinated across an entire cluster.

It helps directly, and the DDoS side stays within HAProxy rather than needing a separate tool. At Layer 7, the HAProxy Enterprise load balancer mitigates application-layer DDoS inline. It applies connection limits and global rate limiting through the Global Profiling Engine, and its Bot Management Module, powered by the Threat Detection Engine, identifies and mitigates bot-driven floods. At Layer 4, it protects against connection exhaustion and abuse. For high-volume Layer 3 and Layer 4 floods that saturate the network link or kernel, the HAProxy ALOHA hardware appliance adds patented PacketShield filtering that blocks unwanted packets at wire speed.

It is built in. The HAProxy Enterprise load balancer includes a high-performance WAF that runs inline in the load balancer itself, so you inspect and filter traffic without a separate appliance and an extra network hop. It runs on the Intelligent WAF Engine, which uses non-signature-based detection instead of the static rule lists and regex signatures that traditional WAFs depend on. That means it catches emerging and zero-day threats with high accuracy and very low latency, and there are no signature lists to maintain. It also uses a multi-engine approach, pairing that engine with an optional OWASP Core Rule Set compatibility mode for teams that want rule-based OWASP Top 10 coverage. Even in that mode it is faster and more accurate than a standard ModSecurity deployment, with a fraction of the false positives. Infobip, for example, uses it to protect their public APIs and user portal. Learn more on our web application firewall solution page - https://www.haproxy.com/solutions/web-application-firewall
