Flexible & Adaptable

We allow teams to work with technologies and processes they trust. The Signal Sciences web protection platform supports any cloud, container, PaaS, or technology stack while providing seamless strategic and tactical visibility. This menu of deployment options gives you protection that won’t force you to change architectures or break production traffic.

scalable and elastic

Scalable & Elastic

Our web protection platform is a natural part of your infrastructure no matter what it consists of. It requires no tuning, has virtually no performance impact, and is infinitely elastic. As you scale, the Signal Sciences solution automatically scales with your deployment in real time.

We're driven by solving real problems.

Our background is in the trenches as CISOs, CTOs, security engineers, development, and DevOps leads. While at the forefront of embracing DevOps and cloud, we couldn't find any vendors that actually helped with the problems we faced when defending our applications. After years of building a new approach in house, we launched Signal Sciences to bring these solutions to our customers.
