Mimecast Email Security protects your organizations reputation and productivity from all email-borne threats – inbound and outbound - without robbing you of the controls you need:

Rapidly deployed and immediately effective

Up-and-running in just hours, you’re protected immediately – while our reputation management capabilities minimize false positives, and prioritize good email.

SLAs you can depend on

We offer a set of demanding  security SLAs - 100% service availability, 100% virus protection and 99% spam protection (0.0001% false positives) - all backed by tough financial penalties.

Always responding to new risks

We were the first provider to offer cloud-based data leak prevention.  Our threat response experts specialize in anticipating email security threats and tackling them as they emerge. And our proprietary connection-based spam filtering technology is without peer.

Power Tools that strengthen your whole email management system

Designed and built to fully integrate with all Mimecast services, Mimecast Content Power Tools offers a more powerful email management system. When run in conjunction with our email archiving service, you can identify, via a data leak stored email, if the leak was malicious or accidental.

Simple email security policy administration

Tight integration with Active Directory simplifies the setting and enforcement of organization-wide email security policies. Like all Mimecast services, it dramatically simplifies email management, offering real-time control through a single web console.

Secure communications

Policy based email encryption and a web-based secure email delivery channel ensure message content remains private and secure.

Data leak prevention

Mimecast guards against honest mistakes, identifies malicious intent, and safeguards evidence if there’s a policy breach – securing everything from confidential documents to credit cards and social security numbers.

Improves mail server performance

By removing harmful and unwanted email before it reaches your network, your email server no longer has to process large volumes of unnecessary mail and your bandwidth is kept available to deliver your legitimate messages.

The email security service has two main elements: a Mimecast Secure Email Gateway and Mimecast Content Power Tools – offering data leak prevention and enhanced email stationery.

Together they offer the best possible way to protect your business’s email-borne IP from all threats – internal and external:

• Switch corporate MX records to point to Mimecast
• Route all outbound traffic through the Mimecast platform
• All email traffic routed via the Mimecast platform
• Suspicious connections are dropped
• Multiple signature-based malware inspection is performed
• Zero-hour threat analysis performed to identify emerging threats
• Messages found to contain malware are automatically rejected prior to receipt
• Message content filtering is applied to further reduce unwanted emails
• Policy-based email content, attachment and image filtering is performed
• Messages which trigger a policy are held in a queue for optional review and release
• Secure delivery methods invoked based on message content or sender and recipient rules
• Real-time queues are available allowing you to manage live messages

The Mimecast Secure Email Gateway is built on our massively scalable mail transfer agent (MTA), which acts as your email bridgehead in the cloud, delivering multi-layered malware and spam protection that stops both known and emerging threats before they reach your network. It’s backed by market-leading SLAs: 100% virus protection, 99% spam protection and 0.0001% spam false positives.
