Mimecast Data Leak Prevention vs Proofpoint Enterprise Data Loss Prevention

Mimecast Data Leak Prevention is a cloud-based email control service for organizations seeking to limit accidental or deliberate exposure of sensitive information. It scans headers, subject lines, message bodies, HTML, and attachments for text patterns, words, file hashes, dictionaries, and inappropriate images. Administrators manage granular policies for users and groups in a web console. When a rule triggers, they can block a message, hold it for review, copy it to a group, send it securely, or add content such as a disclaimer. Suspected leaks can be routed through Secure Messaging, and policy-based TLS encryption can protect email in transit. Mimecast describes integration with Microsoft Exchange or Office 365; listed mail environments also include Microsoft 365, Google Workspace, and on-premises or hybrid email. The service can remove hidden Word document metadata such as comments and tracked changes. Mimecast says its policies can support PCI-DSS, HIPAA, and GLBA compliance work. Pricing is on request, with no numeric price or billing term listed for this product.
