EMAIL SECURITY FOR MICROSOFT 365

Co-built with Microsoft, combining specialist IP from MailGuard with the best of Microsoft 365

Email remains the primary vector for cybercrime, with phishing, ransomware and business email compromise (BEC) driving the majority of breaches. MailGuard 365 was co-built by MailGuard with the team at Microsoft and specifically designed to sit natively inside Microsoft 365, re-scanning email as it arrives, and enhancing the security of Microsoft 365 users across the globe. It stops threats that bypass built-in controls and other security layers hours-faster (and sometimes months ahead).

Seamless integration for advanced threat detection

With single-click activation using your Microsoft credentials, MailGuard 365 delivers protection in minutes, no MX or DNS changes, no additional consoles or complex tooling, and no extra load on IT teams, stopping additional ‘zero-day’ threats like ransomware, phishing, and BEC that bypass Microsoft 365 filters, including Defender.  

Cloud-native, proprietary AI-powered security

Powered by more than two decades of email security innovation and specialist AI threat detection, MailGuard 365 identifies and stops threats often hours (sometimes months) before they are seen by native controls alone. 

Evidence-based reporting & insights

Demonstrates the effectiveness of MailGuard 365 in stopping threats beyond Microsoft’s capabilities, using Microsoft metadata and a Microsoft Sentinel integration, allowing administrators immediate access to detailed message metadata, including sender information, email content, and attachments. This transparency allows teams to respond to email-based threats faster and with greater accuracy.
