Secure Email Gateway

Prevent Breaches Through Email Protection

Most successful cyberattacks start with a phishing link in an email or with a compromised attachment. The traditional, single-layer defense approach is no longer enough.

The Secure Email Gateway serves as the entry point for emails coming from outside the organization, shielding the email infrastructure and users from unsolicited emails using multilayer protection. Custom policies, such as those against unsafe attachments, are applied to protect users. Policies to ensure message integrity, such as DKIM, are also easily enforced.

Ensure Continuous and Reliable Email Security

The Open Systems Secure Email Gateway provides real-time metrics of mail traffic—down to the level of individual messages—that include evaluations of incoming and outgoing emails and optionally of spam and malware trends.

It offers rich current and historical detail on incoming and outgoing queues, network usage, and system load, as well as access to all email and system-specific configuration settings and policy rules.

Secure Your Brand

In today’s marketplace, domain spoofing and brand hijacking are significant risks to your brand.

Yet the means to prevent such attacks — via robust Domain-based Message Authentication Reporting and Conformance (DMARC) enforcement — are complex and difficult to implement.

We opt for simplicity. Open Systems DMARC protection is built-in to our Secure Email Gateway, offering deep analytics and reporting to enhance brand protection.
