Mimecast Data Leak Prevention
London, United Kingdom
What it is
Mimecast Data Leak Prevention is a cloud-based service for helping organizations prevent accidental and malicious leaks of sensitive information through email. It scans headers, subject lines, body text, HTML, and attachments for keywords, file hashes, patterns, dictionaries, and inappropriate images. Administrators manage granular policies for users and groups from a web console. When a policy is triggered, they can block a message, hold it for review, copy it to a group, deliver it securely, or add material such as a disclaimer. Suspected leaks can be sent through Secure Messaging, while policy-based TLS encryption protects email in transit. Mimecast describes integration with Microsoft Exchange or Office 365; supported mail environments also include Microsoft 365, Google Workspace, and on-premises or hybrid email. The service can remove hidden Microsoft Word metadata such as comments and tracked changes. Mimecast says DLP 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.
