Managed Email Security

Our managed email security service adds an independent, AI-powered layer of protection against advanced phishing, business email compromise and zero-day email threats.

Powered by Mimecast and designed for Microsoft 365 and Google Workspace, it strengthens native security with advanced detection, secure email gateway controls and real-time remediation.

The Problem with Native Email Protection

Most organisations already rely on Microsoft 365 email security or Google Workspace protections. The challenge is that modern phishing attacks are designed to evade native filtering.

Attackers now use business email compromise (BEC), Payloadless phishing, QR-code phishing attacks, Impersonation and social engineering and Links that become malicious after delive.

  • This leaves security teams with:
  • Limited visibility into sophisticated phishing campaigns
  • Increased risk of credential theft and account takeover
  • Gaps in Microsoft 365 phishing protection
  • Rising compliance and cyber insurance pressure
  • Too much time spent manually triaging suspicious emails
  • Uncertainty around whether native controls are enough
  • The root problem isn’t email volume, it’s detection capability.

    Most native email platforms were not designed to stop modern social-engineering attacks alone.

Built to Stop Advanced Email Threats
Built to Stop Advanced Email Threats

Built to Stop Advanced Email Threats. RelayPoint combines Mimecast email security with AI-driven behavioural analysis to identify attacks that traditional secure email gateway platforms miss. Built for Microsoft 365, Office 365, and Google Workspace environments.

  • Our emaikl security service helps you:
  • Detect phishing, BEC, and impersonation attacks using behavioural AI
  • Add a second layer of protection beyond Microsoft Defender
  • Protect users from malicious links with time-of-click URL scanning
  • Identify anomalous sender behaviour using social graph analysis
  • Automatically remediate malicious emails post-delivery
  • Centralise visibility, policy management, and reporting in one platform
  • The result is a more resilient email security posture with less manual triage and faster threat response.
Why Most Microsoft 365 Email Security Strategies Fail

Many organisations assume Microsoft Defender alone provides complete phishing protection for Microsoft 365.In reality, advanced email threats are specifically designed to bypass native controls.

  • Our email Security Service closes those gaps by adding:
  • Independent AI-powered threat detection
  • Secure email gateway capabilities for inbound, outbound, and internal mail
  • Business email compromise protection using behavioural analysis
  • Office 365 phishing protection with automated remediation workflows
  • Protection against payloadless and zero-day threats
  • Threats are prioritised based on attacker behaviour, not just signature matching.
