DomainLens Pro

DomainLens Pro grades the security of any domain in one scan, and runs that scan from your phone. Type a domain name, or an IPv4 or IPv6 address, and DomainLens Pro checks it with 28 built-in services, then gives you a clear A–F grade, a score out of 100 and exactly why. WHAT ONE SCAN COVERS • Identity: registration data over RDAP with WHOIS fallback, domain age, expiry and risk signals • DNS: every common record type, DNSSEC, CAA, zone-transfer checks, nameserver delegation • Email: SPF, DKIM, DMARC, MTA-STS, TLS-RPT, BIMI, DANE and a live SMTP STARTTLS check • TLS / Certificates: the certificate chain, protocols, ciphers, forward secrecy and post-quantum (ML-KEM) readiness • Headers: HSTS, CSP, frame, cross-origin and permissions policies, plus cookie flags • Web Stack: detected technologies with the evidence for each • Exposure: exact-version CVE lookups, subdomains from Certificate Transparency, takeover risks, exposed paths • Infrastructure: IP, ASN, hosting, CDN/WAF, location, reverse DNS and RPKI • Intel: what changed since your last scan, recent certificate issuance and blocklist reputation GRADING YOU CAN TRUST Seven weighted categories make up the score. Serious problems cap the grade (an expired certificate is an F whatever else is right), and the report says why. A check that can't run says so instead of looking clean. BUILT FOR REAL WORK • 12 result tabs, from Overview to Export • On-device AI: on phones with Gemini Nano, Analyze This Scan explains the results and what to fix first, right on your phone • 7 export formats: PDF, HTML, Markdown, text, CSV, JSON and an AI Prompt that briefs your AI assistant on what's still open • Scan devices on your own network (private IP addresses) from your phone • Share a read-only report link that expires when you choose • Open scan links straight into the app • 10 themes, including a color-blind-safe Accessible theme • 7 languages: English, 中文, हिन्दी, Español, العربية (right-to-left), Français and Deutsch PRIVATE BY DESIGN Scans run from your phone. No account is needed to scan. Sign in (Google, Microsoft, GitHub, Apple, a passkey or an email code) only if you want your scan history synced with the web app, the browser extension and your other devices. No ads and no tracking. (On phones that run Gemini Nano, Google's ML Kit sends Google anonymous usage diagnostics; see our privacy policy.) Also on the App Store for iPhone, iPad and Mac, on the web, and as a Chrome extension. Learn more at domainlenspro.com. Made by Ægyrix, LLC.
