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.

The perfect response to ‘I already have an IT guy’
We've had great success using Radar during discovery conversations. When a prospect doesn't receive a perfect score, it naturally opens the door to a deeper discussion around security gaps, risk exposure, and best practices. Instead of us pitching what might go wrong, Radar gives them something concrete to look at. We've used this approach with our last five prospects, and three of them have moved forward as new managed clients.
Frequently Asked Questions
How much does Radar cost?
Radar is completely free to use.
How often can I run a test?
As often as needed. Radar is useful any time changes are made to an email configuration, or as a regular health check. Down the road, we’ll add even more features to help you view the big picture of your email security over time, so stay tuned.
How is this different from tools like MX Toolbox?
Most tools check whether records like SPF, DKIM, and DMARC are present and correctly formatted. Radar tests whether they actually work in practice by sending a real email and analyzing a full delivery loop.
What security checks does Radar perform?
Radar checks eight key areas: SPF, DKIM, DMARC, inbound TLS encryption, outbound TLS encryption, reverse DNS, email spy tracking, and IP reputation. Each is scored and weighted toward a maximum of 850.
What does the score mean?
Scores fall into one of four categories:
- 0–399: Critical vulnerabilities that should be addressed immediately.
- 400–599: Several warning factors that need to be looked into.
- 600–749: Solid measures are in place, but there's still room for improvement.
- 750–850: You've nailed it and can now go brag to all your friends.
What happens to my email address?
It’s used only to run your security test. Mailprotector does not use it for marketing, does not sell it, and does not share it with anyone.
Radar surfaces the gaps. Mailprotector closes them.
