**Important Information*** The Mimecast Security Agent (MSA) is for corporate use and only works with the Mimecast Web Security service which is licensed separately. The iOS device it is deployed or downloaded to must be in Supervised mode. Overview Mimecast Web Security is designed to protect your organization's employees against malicious and inappropriate websites based on configurable policies and Mimecast’s threat intelligence capabilities. Protecting at the DNS level, and using an intelligent proxy to analyze suspicious sites, Mimecast Web Security is fast to setup and simple to manage. The Mimecast Security Agent (MSA) for iOS ensures that web access from iOS devices is always protected, whether used in the office, at home or from just about anywhere in the world. Users can check the agent status to know whether they’re protected and see recent blocked activities. They will also see a device notification if using an app that connects to a domain that is blocked by corporate policy or if it is harmful.
