Mimecast Overview

Email and collaboration are where work happens — they’re also where risk is concentrated. Mass consolidation on a handful of cloud platforms like Microsoft 365 and Google Workspace has created irresistible targets; and malicious actors target them relentlessly, using the top attack vector — email — to deliver everything from phishing to ransomware.

And they count on a key constant to achieve their aims — the propensity of humans to make mistakes. It’s no surprise that 91% of cyberattacks start with email or that 94% of successful breaches involve some form of human error.

At the same time, technology is not infallible. Our total dependence on it makes organizations more vulnerable than ever.

How has the security industry responded to these challenges? By creating a complex web of point products designed to address critical areas of risk. However, this approach has generated a level of complexity that’s untenable. Put simply, IT and security teams are spending more time managing technology than risk.

This is how you work protected

Protect Communications

Your work surface is now your risk surface, with email serving as the entry point for 91% of cyberattacks. Block even the most sophisticated email threats, keep email flowing no matter what, and trust your communications again with the Mimecast Product Suite.

Protect People

When successful cyberattacks are analyzed, they typically have one thing in common — human error. Create security savvy employees and surround them with protection all the way down to the point of risk with the Mimecast Product Suite.

Protect Data

Integrate seamlessly with Microsoft 365

Keep email security with Mimecast – your must-have security layer for M365.

Mass adoption of M365 has made it an irresistible target for cybercriminals. Every day, organizations are exposed to unnecessary risk from attacks that could have been blocked.

This quick adoption has increased risk to businesses, particularly regarding email security. As a result of tight budgets and limited resources, many companies have moved away from the best practice of layered security and centralized protections with a single technology provider instead.

To ensure their businesses remain safe, IT and security personnel must learn about the cybersecurity risks of mega-platform providers, the gaps that exist and how to build a cyber resilience strategy

That is why Mimecast has focussed on being able to integrate seamlessly with M365, offering:

  • Rapid deployment
  • Decreased risk exposure
  • Fast, easy integration with Azure Sentinel
  • Unified administration console

Mimecast: DMARC Analyser

Protect your brand by stopping direct domain spoofing
Cybercriminals consistently take advantage of how easy it is to impersonate an organization’s email to dupe their customers, supply chain, and even their own employees. Domain spoofing, where an attacker essentially forges your email to make it look as though their communication has come from a trusted source, is a common tactic used in phishing campaigns and business email compromise (BEC). It’s a big reason why email continues to be the tool of choice for cyber attackers.

Ignoring this problem can significantly impact your brand reputation, business relationships, and the successful delivery of your own outbound business email. To successfully combat this type of attack you need full visibility into all email senders using your domain to identify legitimate versus fraudulent senders. Enter Domain-based Message Authentication Reporting and Conformance (DMARC).

What is DMARC and how does it work?

DMARC is an email validation system designed to uncover anyone using your domain without authorization, and ultimately block delivery of all unauthenticated mail. It builds on existing SPF and DKIM authentication techniques by adding a critical element, reporting.

DMARC reports provide detailed information about who is sending email using your domains. Using this information, you can specify what to do when emails fail DMARC authentication checks.


DMARC empowers email senders and receivers



  • See who is sending email on your behalf, what mail is legitimate and what is not.
  • Publish a DMARC record to instruct ISPs what to do when email doesn’t pass authentication.
  • Protect customers and your supply chain against phishing attacks using your owned domains.


  • Distinguish between legitimate and fraudulent senders; quarantine or reject mail from all unauthenticated sources.
  • Protect employees by stopping impersonation and phishing attacks using your owned domains before they reach inboxes.

DMARC is an email validation system to protect your business’ email domains from being used in cybercrimes like spam, BEC, and phishing.
