Abstract
A cloud-based email system is accessed by way of a cloud access security system. The cloud access security system allows for encryption of incoming emails and outgoing emails stored in the cloud-based email system. The cloud access security system includes a protocol proxy for providing an interface between a client computer of a user and the cloud-based email system, an encryption module for indexing and encrypting emails, and an event listener for receiving email event notifications from the cloud-based email system and replacing emails with corresponding encrypted emails. The cloud access security system may receive encryption keys from a key manager hosted by a key server, which may be part of the cloud access security system or hosted on premise in the same private computer network as client computers employed by users.
