About

Atmosec provides continuous SaaS Security by automatically securing new services and functions as fast as the hyperconnected SaaS ecosystem evolves. Atmosec understands contextual security settings, including the behavior between third-party services to automate and simplify the mitigation of actual and potential risks.
