    Secure Email Gateway


    Secure email against present and future targeted cyber threats and phishing attacks

    Mimecast Secure Email Gateway protects organizations and employees from spear-phishing, malware, spam and zero-day attacks by combining innovative applications and policies with multiple detection engines and intelligence feeds to keep sophisticated attackers out. 


    The challenges of email security

    Email is the #1 communication channel used both by organizations and cybercriminals, enabling malware delivery, phishing, impersonation attacks, and the spread of cyber threats that are already internal to your organization.

    Millions of organizations use Microsoft Exchange, Microsoft 365, Google Workspace, or a hybrid environment – all of which can open the door to cyberattacks. Traditional approaches to secure email gateways are no longer enough. If you think of email security being single-layered and focused on anti-virus and anti-spam, your organization is vulnerable to targeted email-borne attacks. As in the times of on-premises Exchange, you shouldn't rely on Microsoft 365 to deliver the sophisticated security your organization requires.

    Attack methods are quickly evolving and growing more sophisticated, targeted and dangerous. Right now, the industry is faced with email-borne threats such as phishing attacks delivering malicious attachments and URLs; impersonation attacks fueled by social engineering and aimed at tricking employees; and ransomware attacks that can encrypt your data and take entire systems offline.
