Regardless of where your applications operate, Fastly can protect them at scale. We empower developers and security teams with solutions that provide visibility, control and actionable insights.


Award-winning protection and customer support 

Our innovation and effectiveness have been recognized by industry analysts: Gartner has recognized our next-gen WAF (formerly Signal Sciences) in the Gartner Magic Quadrant for Web Application and API Protection in each of the past three years. Our combination of superior customer support and technical capability resulted in also being named a Gartner Peer Insight Customers' Choice recipient three years in a row.

Flexible deployment and easy management 

Security should work with you, not against you. Fastly empowers your development, operations and security teams to deploy and effectively manage the protective capabilities that bolster your organization’s security posture.

Protection without impacting performance

Our DDoS, next-gen WAF and TLS offerings provide the protection and control you need, without sacrificing performance.

App security your developers will love

Security should be a core part of the application development lifecycle, not just bolted-on. Our security offerings provide software teams the visibility necessary to integrate security into the DevSecOps lifecycle.


Web application and API protection

Protect your web apps and APIs at scale, no matter how you deploy them. Our next-gen Web Application Firewall (WAF) and Runtime Application Self Protection (RASP) solution protects your organization’s entire application portfolio and provides the visibility that empowers DevOps teams to make their apps more resilient.
