Startup security scanner
See what buyers, investors, and partners can already check from the outside.
Early teams rarely have a full security program, but prospects still look for public signals. RedScore turns DNS, email, headers, TLS, and exposure into a 0-100 score with clear next steps. No sales call and no signup required.

AI summary
DMARC enforcement is missing, which leaves spoofing open. SPF is too permissive. Several key web security headers are absent.
Why startups scan early
Questionnaires, pilot checks, and investor diligence often begin with external posture: email auth, TLS, headers, DNS hygiene, and exposed services. RedScore shows those gaps before they slow a deal or pilot.
Built for early teams
Get a credible external score and a short fix list without hiring a security team or opening a six-figure vendor contract.
Run a scan before a demo, pilot, or security questionnaire and know where you stand in about 60 seconds.
Category grades across DNS, email, web, exposure, and reputation mirror the outside view prospects check.
Plain-English priority so founders and operators know which public gaps to close before the next conversation.
Claim your domain to rescan, track score changes, and show cleanup progress over time.
What you get
One scan gives you a 0-100 RedScore, letter grades across ten areas, and a short summary of what failed and what to fix next. Enough signal for diligence without dumping raw scanner output on a prospect.
