Validation en temps réel de la chaîne de confiance X.509, compte à rebours d’expiration, énumération SAN et audit des protocoles TLS.
Stateless edge execution • Zero database retention • No user tracking or behavioral profiling
Every network lookup executes inside a temporary, isolated V8 sandbox deployed across Cloudflare's global edge. Each isolate is instantiated on demand, parses public DNS or TLS socket records in transient RAM, returns the result stream, and terminates immediately.
IncogSay operates under a strict zero-retention guarantee. Target domains, submitted URLs, and user IP addresses are never written to disk, stored in relational databases, or logged in persistent files. We do not maintain historical query logs or link lookups to user identities.
All tools are completely free and functional without registration, user logins, or account creation. We never deploy invasive session fingerprints, third-party analytics trackers that capture input payloads, or behavioral profilers. Your queries remain ephemeral and anonymous.

Cliquez sur "VÉRIFIER LE CERTIFICAT SSL" pour initier une négociation TLS depuis notre nœud edge.
Examinez l’autorité de certification (CA), la liste des noms alternatifs (SAN) et la date d’expiration exacte.
Assurez-vous que la chaîne de certificats intermédiaires est complète pour éviter les avertissements mobiles.
Le chiffrement TLS est devenu un standard universel du web. Avec la réduction progressive des durées de validité des certificats (souvent 90 jours), des outils d’audit automatique et régulier sont indispensables pour anticiper les renouvellements.
Every SSL diagnostic query performs a live cryptographic handshake with port 443 of the target hostname, evaluating certificate chain integrity, cipher negotiation, and Certificate Transparency logs.
Validates that the server serves the complete, ordered chain (End-Entity → Intermediate CA → Root CA), preventing mobile and Linux curl clients from failing due to AIA chasing gaps.
Verifies TLS 1.3 priority and confirms deprecation of insecure TLS 1.0 and 1.1 protocol suites. Ensures ECDHE key exchange ciphers for forward-secret session security.
Extracts all Subject Alternative Names (SANs) from the X.509 v3 extension. Detects common wildcard vulnerabilities where apex domains are omitted from *.domain.com certificates.
Cross-checks issuer fingerprints against public, tamper-evident Certificate Transparency logs to proactively flag unauthorized or rogue CA issuance events.
Common administrative and operational scenarios solved by this tool
With modern CAs issuing certificates valid for only 90 days, automated renewal hooks (Certbot, acme.sh) can silently fail due to DNS validation timeouts or rate limits. Real-time auditing surfaces expiration windows before production traffic is blocked.
While desktop Chrome caches intermediate CA certs, mobile browsers (iOS Safari, Android Chrome) and API clients strictly fail with SEC_ERROR_UNKNOWN_ISSUER if the server neglects to send the intermediate bundle. Our audit catches missing chain links instantly.
Verify that your certificate covers all required hostnames, apex domains, and subdomains (e.g. both example.com and www.example.com or api.example.com), preventing ERR_CERT_COMMON_NAME_INVALID errors across distributed microservices.
Confirm your web server enforces TLS 1.3 or strong TLS 1.2 with forward secrecy (ECDHE), while deprecating legacy TLS 1.0, TLS 1.1, and CBC ciphers to maintain strict compliance with PCI DSS 4.0, HIPAA, and SOC 2 transit standards.
