Free SSL/TLS Certificate Checker & Expiry Monitor
Inspect certificate validity, days until expiration, Certificate Authority (CA) trust chain, Subject Alternative Names (SANs), TLS 1.3 ciphers, and GIGW 3.0 / CERT-In encryption compliance in milliseconds.
Why Continuous SSL & TLS Monitoring is Critical for Indian Websites
Under Indian digital governance standards, every public-facing portal is subject to mandatory HTTPS enforcement. An expired or poorly configured SSL certificate causes immediate browser security warnings, disrupts critical public services, and disqualifies government contractors during STQC technical evaluations.
When a certificate expires, Google Chrome and Microsoft Edge display severe full-screen warnings (NET::ERR_CERT_DATE_INVALID), causing up to 98% of citizen visitors to bounce.
CERT-In guidelines mandate disabling legacy TLS 1.0 and 1.1 protocols. Servers must support TLS 1.2 or TLS 1.3 with forward secrecy and authenticated encryption ciphers (GCM).
Bidders participating in Government e-Marketplace (GeM) tenders must submit STQC-compliant web architectures verified for HTTPS port enforcement and valid certificate chains.
Frequently Asked Questions
How often should an SSL certificate be inspected?▼
Automated checks should be performed weekly. With industry standards moving toward shorter 90-day certificate lifetimes, monitoring renewal status at 30 days and 7 days remaining ensures zero unexpected downtime.
What is the difference between TLS 1.2 and TLS 1.3?▼
TLS 1.3 eliminates obsolete, vulnerable cryptographic algorithms (like MD5, SHA-1, RC4, and static RSA key exchange). It reduces the cryptographic handshake from two round trips to one (0-RTT), speeding up connection times by up to 30%.
Does this tool store or log my private encryption keys?▼
No. The tool only performs a standard TLS handshake and reads the public certificate broadcasted to all web browsers. Private keys never leave your server and cannot be accessed over the network.
