Email Security

Protect the organization with comprehensive, multi-layered email security and content controls

Mimecast Secure Email Gateway uses sophisticated, multi-layered detection engines and intelligence to protect email data and employees from malware, spam, advanced threats and zero-day attacks.

With over 18,000 customers, Mimecast’s threat intelligence and adaptive network are constantly improving defenses to eliminate new and advanced threats. Contain spear-phishing attempts by reviewing every URL for threats and make sure spam and malware don’t reach your network.

The majority of organizations have no solution for preventing data leakage. With Mimecast, policies are set centrally and employee applications secure data so organizations don't risk compliance and policy violations whether in an on-premises, cloud or hybrid environment.

The Mimecast secure email gateway provides:

  • Better security and system performance with the ability to stop known and advanced email threats before they reach your network.
  • A single cloud platform with threat intelligence that updates instantly and extends easily to control sensitive data.
  • Ultimate administrator visibility and control to rapidly and consistently apply policies across the organization.
