Castle provides a very nimble, no-code platform to identify risk within the electronic fingerprint of users that sign into their accounts. Castle ingests the data points that most organizations either ignore or aren't aware of (e.g., mobile device operating system, internet service provider, IP location) to identify bad actors, account takeovers, or levels of risk that organizations aren't comfortable with. The solution is easily deployed and easy to maintain. Lastly, the Castle team is fantastic to work with and typically responds to questions within an hour, which is incredible.
