Is certdesk live?

Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.

Is certdesk free to use?

Yes — the hub reached it with no key and no payment.

What tools does certdesk have?

7 tools: check_security, check_certificate, check_dns, watch_expiry, check_dns_propagation, check_expiry, explain_tls_error.

Is certdesk safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• check_security reads unknown 22h ago

  Security posture check of a web server (no port scanning): TLS protocol support (legacy 1.0/1.1 detection via a Korean network probe), security headers (HSTS/CSP/X-Content-Type-Options/anti-clickjacking/Referrer-Policy), HTTP→HTTPS redirect, and certificate key/signature strength. Returns per-item pass/warn/fail and an overall grade.

• check_certificate reads unknown 18h ago

  Check one domain's TLS certificate and return a verdict: status OK | WARN | CRITICAL | UNKNOWN, judged from the certificate chain the server actually serves. Measured from Korean point A (full chain and CRL revocation) plus Korean point B and an overseas point on the Globalping public measurement network (per-point results in measuredFrom; disagreement between points is a WARN). Checks: verification (expired, not yet valid, hostname mismatch, self-signed, untrusted root, missing intermediate, revoked via CRL), days left, renewal point, a newer certificate issued but not deployed (CT logs), the served chain, which old platform versions trust its root or cross-signs (compat: oldest Android, iOS, macOS, Windows, Java and Firefox versions), and the issuing CA's incident history. If the server cannot be measured the status is UNKNOWN and CT logs are shown only as an estimate, never as OK. Set detail=true to include the full chain in the text output.

• check_dns reads unknown 18h ago

  DNS and hosting facts for a domain: nameservers with DNS provider, A/AAAA with IP owner (ASN), CNAME, MX, CAA (which CAs may issue), SPF/DMARC, DNSSEC, registrar and domain expiry (RDAP).

• watch_expiry changes data unknown never probed

  Subscribe an email address to free daily expiry monitoring of up to 5 domains (certificate, domain registration and security grade) with email alerts, plus an optional Slack/Discord/Telegram/webhook channel. Also alerts when Certificate Transparency logs show a new certificate for a domain from a CA not seen before (possible unauthorized issuance). Double opt-in: a confirmation email is sent and monitoring starts only after the recipient clicks the link; one confirmation email per address per 24 hours. Use only an address the user owns and explicitly asked to use.

• check_dns_propagation reads unknown 18h ago

  Compare answers for one DNS record across resolvers: the authoritative nameservers, Korean ISPs (KT, SK Broadband, LG U+) and public resolvers (Cloudflare, Google, Quad9, OpenDNS), measured from a Korean network. Use it to confirm a TXT/CNAME for certificate domain validation (e.g. _acme-challenge) has propagated.

• check_expiry reads unknown 22h ago

  Verdict for up to 5 domains at once: status OK | WARN | CRITICAL | UNKNOWN per domain combining the served certificate (verification, days left, null when the server cannot be measured) and domain registration expiry (RDAP), plus Korean alert lines. Use this for inventories, CI gates (fail unless status is OK) and periodic checks.
