What an agentless security scan actually sees

No agents, no code access, no installation — just your domain. Here's the surface Secureefy Scan probes from the outside, the way an attacker would.

Security Research

Agentless scanning means we test your site the way the internet sees it: from the outside, without touching your servers. It's safe for production and takes seconds to start.

The external attack surface

TLS & certificates — protocol/cipher strength, expiry, chain
Security headers — HSTS, CSP (deep directive analysis), X-Frame-Options, and more
Exposure — open ports, server banners, information disclosure, directory traversal
Reputation — VirusTotal (70+ engines), Google Safe Browsing, Spamhaus/SURBL blacklists
DNS & email — DNSSEC, CAA, SPF, DKIM, DMARC, BIMI
Takeover risk — dangling CNAMEs to S3, Azure, GitHub Pages, Netlify, Vercel

Every finding comes with a severity, a score, and a fix — then our AI layer rolls it all into a single grade from A to F and a summary a non-engineer can act on.
