Email Security With Targeted Threat Protection



Mimecast’s cloud-based Secure Email Gateway protects organizations and employees using any cloud or on-premises email platform. It defends against inbound spear-phishing, malware, spam and zero-day attacks by combining innovative applications and policies with multiple detection engines and intelligence feeds.

Your information, and ultimately your business’ reputation, is protected by outbound scanning of all emails to block threats and prevent malicious or unintentional loss of sensitive or confidential information.

Email protection inside your network and the organization



Even with a robust email security perimeter in place, attackers can try to bypass your perimeter and operate inside your email network. Your users are a fundamental line of defense, inside the perimeter, to help defeat attacks using social engineering to compromise accounts.


Mimecast Awareness Training can help dramatically reduce risk related to human error, but technology controls are essential to counter insider email threats.

Internal Email Protect


For most, inbound email-borne spear-phishing style attacks are the primary focus for security teams, but that doesn’t sufficiently protect an organization. It is important to recognize that internal-to-internal emails as well as outbound emails are regularly used to spread threats and spam. In addition, organizations need to ensure they are protected against delivered email-borne files which are later determined as malware.

Mimecast Internal Email Protect extends Mimecast’s security controls to your organization’s internally-generated emails providing 360 degrees of email protection.

Email security beyond your perimeter


Without confronting an organization’s perimeter or trying by other means to get inside its email network, it is quite easy for cyberattackers to impersonate a brand on the internet. They can leverage and ultimately destroy the value and trust that a brand owner may have taken years or decades to build.
