See what needs fixing on your site — and verify the improvement. GuardPad scans a website's security configuration from your iPhone or iPad, shows the three fixes that matter most, explains each one in plain language, and — after you change your server — rescans and tells you finding by finding what is resolved, still present, new, or could not be verified. Built for freelance developers and small web agencies who look after client sites. Try every PRO feature free for 3 days. No account. No analytics. Scans run on your device. UNDERSTAND • An A+ to F grade that summarises the checks performed — with a clear note that a grade is not a guarantee of security or a certification • 11 graded HTTP security headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP, COEP, CORP, X-XSS-Protection, Server) • SSL/TLS certificate and protocol details, including post-quantum key exchange detection • Cookie flags (Secure, HttpOnly, SameSite, __Host- prefix) • Email security: SPF, DMARC, DKIM, MTA-STS and BIMI • Redirect chain, deprecated headers, security.txt, WAF/CDN fingerprints • OWASP Top 10:2025 and PCI DSS 4.0 header check mapping FIX • "Fix first" — your highest-impact issues at the top of the results • For every finding: what was observed, why it matters, and what to change • PRO: server config snippets for nginx, Apache, Express.js and Caddy VERIFY • Rescan to verify: each earlier finding is marked Resolved, Still present, New or Not verified • An unchanged overall grade never hides a finding you fixed • Incomplete scans (for example when the web server is unreachable) are never counted as fixed • PRO: PDF and Markdown reports that include what was verified since the previous scan FOLLOW UP (PRO) • Pin up to 5 domains; when iOS allows, GuardPad re-scans them in the background and notifies you only when a grade or header changes. Each pinned domain shows when it was last checked. Background re-scans are periodic, not continuous. Yearly covers all pinned domains; Lifetime covers 1. • Certificate expiry reminders 30/14/7/3/1 days before expiry • Grade trend charts, posture dashboard and scan comparison • Batch scan up to 50 URLs, CORS tester, DNS lookup with DNSSEC and CAA, full certificate chain • Shareable grade card and README badge NATIVE ON iOS • Share Extension — scan a URL straight from Safari • Siri & Shortcuts — "Scan Domain" and "Get Last Grade" • Home Screen and Lock Screen widgets for pinned domains • Optimised for iPhone and iPad FEEDBACK Spotted an incorrect result? Report it from the finding itself. You see the full message before anything is shared, and you send it yourself from Mail. PRIVACY No account, no analytics SDKs, no tracking, no third-party dependencies. Scan results stay on your device. GuardPad is a tool for checking the configuration of websites you own or are permitted to scan.
