SSL/TLS Processing

Secure, high-performance traffic encryption

Protect your application traffic and safeguard sensitive data. Enable high-performance SSL/TLS termination and end-to-end encryption between your clients, HAProxy nodes, and backend servers.

The Problem

SSL/TLS introduces tradeoffs between security, performance, and integration

While essential, SSL/TLS processing often adds measurable latency to each request, which quickly adds up at scale and can impact overall performance. 

Many application delivery platforms require dedicated SSL/TLS processing hardware to maintain good performance. They can also fail to support the latest protocol standards — limiting how organizations can incorporate SSL/TLS into their tech stacks.

Speed matters

SSL/TLS processing incurs the largest performance hit during the handshake — especially on servers lacking ample CPU resources.

Implementation is lagging

21% of Amazon Alexa's top 100,000 websites don't use HTTPS, hinting at performance or implementation concerns.

The Solution

HAProxy delivers flexible, high-performance SSL/TLS support

Boost application security while adding nearly zero latency. OCSP stapling, zero round trip time resumption (0-RTT), SSL/TLS session resumption, HTTP Strict Transport Security (HSTS), and more safeguard your traffic management. 

Best-in-class performance + -

HAProxy forwards over 2 million HTTP requests per second on a single Arm-based AWS Graviton2 instance

Learn how HAProxy achieved over 2 million requests per second (RPS) over SSL/TLS — without incurring performance penalties or facing bottlenecks — on just one Arm processor.

Automating and simplifying management for your public-key infrastructure (PKI)

HAProxy offers streamlined management and loading of thousands of certificates. Organizations can also enable server name identification (SNI) and use their preferred certificate authority with HAProxy — such as Let's Encrypt

Secure and high-performance encryption

Ensure data confidentiality and integrity with modern SSL/TLS encryption while maintaining optimal speed and reliability. HAProxy minimizes encryption overhead, allowing secure communication without sacrificing performance.

Minimal latency and resource usage

Optimize connection overhead using stateful and stateless session resumption, Keep-Alive, and connection reuse — reducing latency and improving server responsiveness.

Mutual TLS (mTLS) authentication

Implement mutual authentication between clients and servers using mTLS. By verifying both parties’ identities, mTLS strengthens security for applications, APIs, and zero-trust architectures.

Asynchronous cryptography

Perform cryptography operations asynchronously, improving efficiency for high-throughput environments and maintaining low latency under heavy loads.

Flexible encryption

Automatically use Elliptic Curve Cryptography (ECC) and RSA encryption algorithms — and the latest TLS 1.3 cypher suites — according to your use case.

Intelligent traffic routing

Match access control list (ACL) rules to SSL/TLS data. This enables smarter, dynamic traffic routing based on your security policies.

What are users saying about HAProxy SSL/TLS processing?

“HAProxy Enterprise allows us to very reliably load balance between all of our components. It allows us to handle all SSL terminations while updating configurations very easily. It provides a ton of flexibility that saves us significant development time. Now, we can focus our time on making the overall developer experience better and building out new features for our customers.”

Tobias Haag Software Engineer Lead @ Microsoft Yammer

"HAProxy is fast, it will run well on the lowest spec hardware, and you don't even need to think about resources until you have tens of thousands of connections. Config changes, even things like adjusting TLS ciphers, can be completed with a service reload, which won't impact app availability. Coming from a windows environment where this would need a reboot is a breath of fresh air."
