How Dartmouth avoided vendor lock-in and implemented LBaaS with HAProxy One

History is everywhere at Dartmouth College, and while the campus is steeped in tradition, its IT infrastructure can’t afford to get stuck in the past. In an institution where world-class research and undergraduate studies intersect, technology must be fast, invisible, and – above all – reliable. That reliability was put to the test when Dartmouth’s load balancing vendor was acquired twice in five years, as Avi Networks moved to VMware and VMware moved to Broadcom.

Properly securing OpenClaw with authentication

OpenClaw (née MoltBot, née ClawdBot) is taking over the world. Everyone is spinning their own, either on a VPS, or their own Mac mini. But here's the problem: OpenClaw is brand new, and its security posture is mostly unknown. Security researchers have already found thousands of publicly available instances exposing everything from credentials to private messages.

Universal Mesh in action: how PayPal solved multi-cloud complexity with HAProxy

The hardest part of modern infrastructure isn’t choosing your deployment environments — it’s bridging communication between them. Large enterprises are constantly facing the challenge of keeping everything connected, secure, and fast when their infrastructures are spread across different clouds and on-premises systems.

How LinkedIn modernized its massive traffic stack with HAProxy

Connecting nearly a billion professionals is no small feat. It requires an infrastructure that puts the user experience above everything else. At LinkedIn, this principle created a massive engineering challenge: delivering a fast, consistent experience across various use cases, from the social feed to real-time messaging and enterprise tools.

Fresh from AWS re:Invent: Supercharging HAProxy Community with AWS-LC Performance Packages

The timing couldn’t have been better. Last week, the tech world descended on Las Vegas for AWS re:Invent. It was the perfect venue to talk about cloud infrastructure, scale, and the future of application delivery. While we enjoyed talking shop at our booth, we didn't just bring swag and demos; we brought a significant performance improvement for our open-source community.

Sanitizing HTTP/1: a technical deep dive into HAProxy's HTX abstraction layer

HTTP/1.1 is a text-based protocol where the message framing is mixed with its semantics, making it easy to parse incorrectly. The boundaries between messages are very weak because there is no clear delimiter between them. Thus, HTTP/1.1 parsers are especially vulnerable to request smuggling attacks.

Revolutionizing application security with the next-gen HAProxy Enterprise WAF

The state of web app, API, and AI service security is in constant flux, with threats seemingly lurking around every corner. For years, organizations have relied on web application firewalls (WAFs) as a critical layer of defense. HAProxy Technologies has long provided robust WAF solutions, including earlier versions such as the "Advanced WAF" and "ModSecurity WAF" — based on the popular open source WAF engine. These excelled against widely-known OWASP Top 10 threats.

HAProxy Enterprise WAF Protects Against React2Shell (CVE-2025-55182)

On December 3, 2025, the React team announced a critical security vulnerability in React Server Components (RSC). Identified as CVE-2025-55182 (and covering the now-duplicate CVE-2025-66478), this flaw allows unauthenticated attackers to execute arbitrary JavaScript code on backend servers.
