What does Radar Lite check?

Radar Lite takes a domain name and delivers a prioritized security assessment in under a minute. It checks email authentication protocols, DNS configuration, TLS certificates, and web security headers, then explains what's wrong, why it matters, and what to do about it.

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.”

Introducing Red Sift Radar Lite: AI-powered security for everyone

Security scanners are great at flagging issues, but terrible at telling you which ones matter. Your TLS is outdated, your SPF has syntax errors, your DMARC is set to “none.” Now what?

Radar Lite helps you answer that question. It analyzes your domain’s security and turns raw findings into clear priorities, so you know what to fix first and why.

FAQs

What does Radar Lite help me do?

Radar Lite helps you understand where your domain is exposed and what to do about it.

It surfaces issues that could affect deliverability, trust, or security posture, then prioritizes them and puts them in industry context so you’re not guessing what matters.

When should I use Radar Lite vs. full Radar?

Use Radar Lite when you need a fast, one-off view of a domain’s security posture. It’s ideal for quick checks, initial assessments, or understanding how a domain compares to others in its industry, without needing setup or access to internal systems.

Use full Radar when you need deeper, ongoing analysis across your environment. Radar connects directly to your Red Sift applications, giving it contextual understanding of your specific setup. This allows it to support multi-step investigations, tailored guidance, and continuous improvement over time.
