What We're Building

Castle is the easiest way to protect your users.

Castle understands user behavior across web, mobile and APIs. Depending on the risk associated with an individual device, we automatically trigger security notifications, challenges and account reset workflows. This lets end users self-mitigate while also improving Castle's risk models.
