Email Security for Microsoft 365 | RelayPoint by Peritus

RelayPoint Email Security powered by Mimecast

RelayPoint adds an independent AI-powered layer that stops advanced phishing, business email compromise, and zero-day email threats before they reach users. Designed for Microsoft 365 and Google Workspace environments, it strengthens native protection with advanced detection, secure email gateway controls, and real-time remediation.Most phishing attacks bypass native Microsoft 365 protection.

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 bBusiness 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. 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.

RelayPoint 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.

RelayPoint 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.
