Radar looks at 9 Critical Areas
Radar evaluates your domain's authentication stack — SPF, DKIM, and DMARC — to confirm that your outbound mail is properly signed, authorized, and protected against spoofing and impersonation attacks that target your clients and their customers. Radar also checks your blacklist standing, TLS encryption posture, spam filter configuration, catch-all risks, and outbound routing — highlighting the exact gaps that attackers probe before launching a campaign against your domain. The result is a single, weighted score that explains where you stand and what to fix first. Get your score
