Get a quick read on your domain’s security configuration
Radar Lite is a free, AI-powered tool that helps you understand your domain’s security posture. It prioritizes what needs fixing, explains why it matters in plain language, and benchmarks your setup against your industry.
Radar Lite takes a domain name and runs a focused set of security checks across email, DNS, and the web. It’s built to give teams a clear baseline of how their domain is configured, without requiring specialist tooling or deep protocol knowledge.
Email security checks evaluate SPF, DKIM, DMARC, BIMI, and MTA-STS to ensure your email authentication is correctly configured and protected against spoofing.
DNS checks review DNS zone configuration, DNSSEC, DANE, and CAA records to identify misconfigurations that can weaken trust, break encryption, or expose your domain to misuse.
Web security checks analyze TLS configuration, certificates, and key security headers such as CSP, HSTS, and SRI to flag weaknesses that could enable downgrade attacks or data exposure.
“Radar Lite would be an excellent service for most folks below the "corporate-grade" world, e.g. ranging from hobbyists to the "IT person" at a smaller company. It would be most useful to people who run things on the internet but don’t have in-house security personnel or access to fancy consultants.”
“Radar Lite is helpful for a quick overview of suspicious IP addresses, domains, or senders I’m seeing through my tenants. It’s incredibly convenient; I just type “Evaluate xyz.domain” and get an immediate answer without logging in. Anyone who wants passive reconnaissance information or is just curious about a sender could use this with great results!”
“Being able to compare our domain against others instantly adds context. It helps us prioritize with confidence because we can see what’s normal, what’s weak, and where we’re ahead.”
