At Castle, we're on a mission to protect online users against hackers and bots. Our vision is to be the easiest and most developer-friendly way of adding user account security processes to your platform. Using our APIs, companies can track user interactions to figure out when accounts have been compromised, as well as giving their users the ability to recover their accounts eg. by sending out an email notification or text message.
