Mimecast

Mimecast provides cloud-based email security that protects organizations from advanced threats — phishing, ransomware, business email compromise, and spam — while ensuring email continuity and compliance through archiving. For organizations where email is a critical business function and a primary attack vector, Mimecast layers security capabilities on top of existing email infrastructure like Microsoft 365 and Google Workspace.

Advanced threat protection uses multiple detection engines to analyze inbound emails for malicious attachments, URLs, and social engineering tactics. URL rewriting checks links at the time of click rather than just at delivery, protecting against time-delayed attacks where URLs become malicious after the email has passed initial scanning.

Email continuity ensures that employees can continue sending and receiving email during cloud email outages. When Microsoft 365 or Google Workspace experiences downtime, Mimecast's continuity service provides a web-based mailbox and outlook plugin that maintains email access. For organizations where email downtime directly impacts revenue, this continuity assurance is a primary justification for the investment.

Email archiving stores a tamper-proof copy of all email communications with fast search and retrieval. For industries with regulatory requirements — financial services, healthcare, legal — the archive provides the compliance-ready records retention that auditors and regulators demand.

Security awareness training complements the technical email security with human-focused training that helps employees recognize phishing attempts and social engineering attacks. Integration with the threat protection data means training scenarios can be informed by the actual threats the organization faces.

Pricing starts at approximately 4 USD per user per month for basic email security, with additional modules for archiving, continuity, and advanced threat protection increasing the total cost based on the features selected.
