Eight checks, one complete picture
Radar was built to give MSPs a complete view of inbound and outbound email security factors at play.
It performs a series of checks to identify vulnerabilities including inbound and outbound TLS encryption, SPF, DKIM, and DMARC, domain/IP reputation, reverse DNS and email spy tracking.
A credit score for email
After analyzing the email systems in question, Radar weighs the pros and cons and tallies them as a security score. Think of it like a credit score for email.
The higher the score, the stronger the security posture.
Everything you need to act on what Radar finds
A Radar report breaks down every check in plain English—what passed, what didn't, and exactly what to fix.
MSPs receive a clear, actionable summary that's ready to act on for existing clients or start a conversation with new ones.
