End to End Account Security
Trust your good users to weed out the bad
Castle is taking a new approach to account security. Instead of focusing exclusively on the threat, Castle puts user experience at the center of the security model. This user-centric model allows security to focus on enabling the good in addition to stopping the bad. With Castle you can fully automate threat response and account recovery in real-time with risk-based authentication, granular access policies, and custom workflows for end-to-end account recovery.
