HAProxy and HTTP Strict Transport Security (HSTS)

HAProxy provides an easy and straightforward way to add HTTPS to your website. As a load balancer positioned in front of your web servers, it can handle all of the encryption and decryption duties, offloading those tasks from your upstream servers. That’s good because in today’s age of privacy awareness, the consensus is that every website must implement HTTPS, regardless of whether sensitive or private information is being exchanged.

Redirect HTTP to HTTPS with HAProxy

Use the HAProxy load balancer to redirect users from HTTP to HTTPS automatically. For decades, our lives have become increasingly dependent on sending and receiving data from across the Internet. Now, with more people working, studying, and hanging with friends remotely, that trend is showing an uptick. Yet, adversaries seem to be grasping at that communication from every direction.

Serve Dynamic Custom Error Pages with HAProxy

Set up custom error pages in HAProxy to ensure consistent, branded messaging that supports any backend web stack. The memory is probably still fresh: You’re shopping online at your favorite website, looking for something specific, you’ve got it narrowed down to two or maybe three products, you make the final decision, click to checkout and then— Internal Server Error. A cryptic error has replaced the page you were expecting. More than surprised, you feel knocked off balance.

CVE-2020-15598: HAProxy Enterprise Unaffected Due to ModSecurity Hardening Measures!

The OWASP ModSecurity Core Rule Set team has reported a Denial of Service vulnerability in ModSecurity version 3.x that allows an attacker to send a crafted payload that exploits a flaw in how regular expressions are matched within the software. A CVE (CVE-2020-15598) was assigned to this vulnerability and it has been rated with a CVSSv3 score of 7.5 (high).

Is That Bot Really Googlebot? Detecting Fake Crawlers with HAProxy Enterprise

Detect and stop fake web crawlers using HAProxy Enterprise’s Verify Crawler add-on. How your website ranks on Google can have a substantial impact on the number of visitors you receive, which can ultimately make or break the success of your online business. To keep search results fresh, Google and other search engines deploy programs called web crawlers that scan and index the Internet at a regular interval, registering new and updated content.

Become FIPS Compliant with HAProxy Enterprise on Red Hat Enterprise Linux 8

Guarantee strong encryption by enabling ‘FIPS mode’ with RHEL and HAProxy Enterprise. SSL and its successor TLS are protocols that safeguard web traffic as it crosses the Internet, encrypting communication and protecting it from tampering. However, the encryption algorithms within these protocols are subject to change over time as vulnerabilities are discovered or as better encryption methods become available.

Dynamic SSL Certificate Storage in HAProxy

Use the HAProxy Runtime API to update SSL certificates in HAProxy without a reload. When you route traffic through an HAProxy load balancer, you gain the ability to terminate SSL at the load balancer. HAProxy encrypts communication between the client and itself and then sends the decrypted messages to your backend servers, which means less CPU work on the servers because there’s no encryption work left to do.
