To create more secure and resilient web experiences, we must design, build, and execute applications with security top of mind, and consider how the lessons of the past 30 years inform how we think about the future of security.

On November 11th 2021, Fastly Engineering received alerts related to segmentation faults on Compute@Edge. A Fastly investigation into CVE-2021-43790, a bug in Lucet, a dependency of Compute@Edge, is disclosed in a recent Bytecode Alliance security advisory. Fastly investigations have not identified additional impact outside of the single case disclosed in this advisory. It's our goal in this Fastly Security Advisory to illustrate our knowledge about the bug discovered and the actions we have taken to prevent further possible impact to our customers.

Many websites today are really applications, and we should be building them as such. To do that, we need application architectures and networks that are capable of supporting fast, secure, and scalable user experiences. We must embrace a more dynamic mindset in how we approach web development and consider the tools we need to get there.

As we look back to celebrate the 30th anniversary of the website, it’s also worth thinking about the next 30 years. There are a couple of areas where we — as engineers, developers, and builders in general — can champion innovation, mainly around architecture and security.

Compute, our serverless compute environment, can be used to solve headaches dealing with attackers looking to modify and manipulate resources. In this post, we tell you how.

Our Security Research Team provides guidance on how to address CVE-2021-40438, a vulnerability in Apache HTTP Server version 2.4.48 and earlier, by patching impacted version(s) and enabling a new templated rule to prevent exploitation.

The recent Apache HTTP Server vulnerability (CVE-2021-41773) is reportedly being exploited in the wild. Fastly already detects this vulnerability, but our next-gen WAF customers can also create a rule to block exploitation.

Organizations implementing DevOps practices often sacrifice security for speed, exposing them to potential threats. In reality though, many DevOps practices are already primed for security initiatives.

Forrester’s 2021 Annual State of Application Security Report stresses the need for updated application security tools that can be easily integrated into development plans and architecture.

Your organization may have operational and cultural roadblocks to overcome when it comes to integrating security and DevOps. These tips can help you ensure a smooth transition to more secure DevOps.

Compare legacy versus next-gen WAFs to see what sets them apart. Determine if your company can benefit from a next-gen approach.

Our Security Research Team has built and deployed a rule to help protect customers of our next-gen WAF against the recently announced Confluence Server OGNL injection vulnerability, CVE-2021-26084.

Modern applications need modern security tools that include flexible deployment, DevOps support, and strong API protection. Here are the six most important characteristics of modern web app and API security tools.

Companies using an average of 11 web application and API security tools should be able to rest easy, but the vast majority of them report successful attacks are still getting through. These legacy tools aren’t cutting it.

When we acquired Signal Sciences, we put a stake in the ground as a company that cares about the complete delivery path and making it not just resilient and performant, but inherently secure as well. Here’s our update on that mission.

Today, we launched Fastly Secure packages, a unified web app and API security solution that provides “right-sized” protection for any organization at a spend level that works for a variety of budgets.

Here are four repeatable steps that will help you pay down your security technical debt, make your apps and APIs more secure, and move you toward consolidated security tooling.

As the internet landscape gets more complex, more API driven, and more distributed, many security and IT professionals are left wondering — why aren’t the security tools that were good enough a few years ago good enough now?

How to accelerate your WAF visibility from 0 to 100MPH

We released a new report today in partnership with ESG Research that reveals some fascinating insights into the state of web application security tooling.
