DDoS attacks are growing more common and dangerous
Distributed denial-of-service (DDoS) attacks remain serious cybersecurity threats each year — endemic across the web much like the flu or common cold. Such attacks can cause high resource use, downtime, data theft, and revenue loss. Protection is essential.
However, not all solutions are created equally. Many DDoS protection and rate limiting solutions fail to react to threats quickly and globally, while providing affordable 24/7 protection.
Attacks are multiplying
Cloudflare observed 8.5 million DDoS attacks across its domains in H1 2024.
Throughput is rising
During the 2023 NFL Super Bowl, a major DDoS attack peaked at 71 million requests per second (RPS) — the largest ever recorded.
Packets are being weaponized
Attack magnitude is rising annually, with a notable DDoS attack peaking at 1.7 terabits per second in early 2024.
Fast, efficient, and globally-aware security layers provide reliable DDoS protection
Rapid detection and response — plus ultra-low latency traffic processing — deliver cost-effective and reliable, 24/7 protection against DDoS attacks.
Fast and flexible
Detect harmful bots and track real-time client behavior to trigger near-instant response policies. 100% local processing and low resource use help provide cost-efficient protection.
Enforce global protection on-prem and in the cloud with the cluster-wide awareness of HAProxy Fusion and Global Profiling Engine (GPE), and at the edge with HAProxy Edge's global network.
High-performance and customizable protection
HAProxy's next-gen, multi-layered security approach stops botnets and abuse in their tracks.
Write simple response rules using ACLs
ACLs use strings, patterns, request rates, and logical operators to determine routing behaviors. Challenge, deny, and redirect traffic in real time with minimal configuration. Apply custom rules and enforce redirects based on stick table data.
Track activity with Global Profiling Engine (GPE)
View client behavior in real-time across every HAProxy cluster. Dynamically generated counter thresholds, based on historical data, power automated global rate limiting and advanced security analysis. Track suspicious behavioral patterns everywhere and act.
Enable rapid filtering with PacketShield
HAProxy ALOHA's PacketShield offers a simple, efficient, and cost-effective response to DDoS attacks. Enable customizable, real-time packet filtering at wire speed in front of your load balancers and servers — with zero disruptions or false positives.
Stop spam with CAPTCHA module
Our native CAPTCHA module presents a challenge page to clients to determine if they're human. Extend support to multiple CAPTCHA providers — such as Google reCAPTCHA — based on simple rules written in your HAProxy global settings.
Integrated protection against evolving threats
Customizable, integrated bot protection and abuse prevention — without breaking the bank.
Stop threats before they can impact your applications, APIs, and AI services. Define rate limits, challenges, and other protective measures according to your unique traffic profile.
Ultra-low latency threat detection and traffic filtering happen in microseconds, giving users a responsive experience.
HAProxy's comprehensive security features provide full coverage against DDoS attacks, API abuse, application attacks, and other common cybersecurity threats.
HAProxy's high-performance security layers keep resource use and operational costs low. Reliable and optimized protection negates the need for costly attack mitigation while safeguarding revenue.

What are users saying about HAProxy DDoS protection and rate limiting?
HAProxy adeptly aggregates table data from our cluster of load balancers on a real-time basis. Inspecting tag values within our logon messages is done quickly as soon as our client sends them. We can easily modify rate-limiting thresholds for traffic loads that are dynamic in nature.
By building a PoP network based on HAProxy, cross-cutting concerns like authentication, authorization, and rate limiting could be moved to the edge of the network. They increased their service reliability, gained observability over their traffic, and removed single points of failure.
