Check and Test your services
General Checks
Choose a focused check below, or combine observations in a domain health report. TLS certificate inspection and protocol probing share one tool; certificate file operations are under Certificate tools.
Domain health report
Combine DNS, registration, HTTPS, headers and mail policies, with optional service checks and copy, print or JSON exports.
Build a reportTLS certificates and protocols
Inspect HTTPS, mail, FTPS, PostgreSQL and MySQL/MariaDB certificates, identity, validity and presented chains on standard or custom ports. Optionally probe individual TLS versions in the same form.
Check a TLS serviceDNS records and resolvers
Inspect raw records and TTLs, including CNAME, NS, SOA, PTR and TXT. Compare answers from this hosting server’s DNS resolver, Google, Cloudflare or a custom public resolver.
Inspect DNSDNS and mail-policy analysis
Review address, MX and CAA records or analyse SPF dependencies, DKIM keys and DMARC policy. Use this for interpretation rather than resolver comparison.
Analyse DNS policiesRegistration and nameservers
Look up registrar and registration details through RDAP, compare nameservers and inspect related address ownership.
Check registrationHTTP redirects and timing
Trace redirect hops, response status, connected addresses and connection timings.
Trace HTTPSecurity header review
Interpret response security headers and review missing, repeated or potentially weak directives. HTTP tracing alone does not provide this policy review.
