Bridge the Gap Between
DevOps and Security

Today’s security teams need to protect web applications in a variety of languages and across a large technology footprint—without interrupting daily code pushes, constantly tuning rules or drowning in the noise of false positive alerts. Legacy web application firewalls weren’t built for this. Ours is.

Secure your web apps, APIs, and microservices, and bring your security and DevOps teams together with Signal Sciences.
