Real-time diagnostic and reporting; data loss prevention, secure message delivery, email branding and disclaimer management, document conversion and metadata management, real-time online queue management, large attachment management, advanced routing and spooling.[23]
  • Targeted Threat Protection: URL rewriting at the gateway with time-of-click scanning for malicious content before being opened.[24]
  • Large File Send: send and receive large files from Outlook, with encryption, optional access key and custom expiration dates.[25]
  • Secure Messaging: secure email channel for sensitive information either user-initiated or policy-driven.[26]

Enterprise Information Archiving

Mailbox Continuity

The company has not shared any details about the attacks abusing the compromised certificate, but some experts have speculated that the certificate may have allowed the hackers to intercept Mimecast customers' communications.

Mimecast provides email security services that customers can apply to their Microsoft 365 accounts by establishing a connection to Mimecast's servers... A compromise means that cyberattackers could take over the connection, though which inbound and outbound mail flows, researchers said. It would be possible to intercept that traffic, or possibly to infiltrate customers' Microsoft 365 Exchange Web Services and steal information. 'The attack against Mimecast and their secure connection to Microsoft's Office 365 infrastructure appears to be the work of the same sophisticated attackers that breached SolarWinds and multiple government agencies,' Saryu Nayyar, CEO at Gurucul, said via email.
