Comprehensive, Adaptive Business Email Protection through Layered Security

Block Advanced & Emerging Email Threats with Defense-in- Depth Protection

Blocking advanced and emerging cyberattacks requires a defense-in-depth approach to securing business email.

Additional Layers of Security Are Needed to Make Microsoft 365 Email Safe for Business

Despite built-in email protection provided by Microsoft, 85% of Microsoft 365 users have experienced an email data breach in the past year. Critical additional layers of adaptive security delivered by a comprehensive third-party solution are required to prevent credential phishing and other dangerous attacks in Microsoft 365.

Guardian Digital EnGarde Cloud Email Security is engineered to close the critical security gaps that exist in Microsoft 365 with additional layers of proactive protection including complete phishing and malware defense, account takeover protection and expert, ongoing system monitoring, maintenance and support.
