How are we better together?


We come from similar roots. Our founders each tackled a critical technology problem which frustrated developers, but was unsolved by any vendor. They challenged the norms, and built for the needs of modern DevOps and security teams.


We are defined by a common goal: to give developers more power over the security and performance of their apps and APIs. Visibility, control, and speed are core tenets of both platforms. We’ve even integrated with developer toolchains for faster release cycles.


We share a common vision for what modern application security should look like: empowering developers to safely build faster, more agile apps wherever they want, knowing that the future of application development is serverless.

Join the future of a secure web.
