Errors We Help You Fix
The cryptic Java stacktraces and OpenSSL errors that halt deployments — decoded and resolved.
Everything You Need to Debug TLS
Built beyond basic expiry checks — CertLens understands the full PKI stack.
Fix Trust Chain Issues
Instantly identify missing intermediates and root certificates. Get the exact commands to repair your chain.
Analyze Java Keystores
Upload JKS or PKCS#12 files. Inspect every alias, expiry, and chain inside your keystore.
Scan Live TLS Endpoints
Point CertLens at any domain. Get a full chain analysis without touching your server config.
Detect Expiry Early
See exact days remaining for every certificate in your chain. Get colour-coded risk ratings.
Risk & Security Insights
Score your certificate configuration against security best practices. Know your real exposure.
Export Audit Reports
Download full PDF reports of your certificate scan. Share with your team or auditors.
Built Different. For Real Infrastructure.
Most tools just check if a cert is expired. CertLens tells you why it fails and exactly how to fix it.
Built for Real Infrastructure
Designed specifically for banking, SWIFT, and enterprise environments where a certificate failure means a production outage — not just a browser warning.
Beyond Expiry Checks
Understands full trust chains, keystore structures, and the real reason TLS handshakes fail — not just surface-level certificate dates.
Explain, Not Just Scan
Every finding comes with a plain-English WHY, IMPACT, and FIX. Know exactly what went wrong and the precise commands to resolve it.
Learn PKI the Practical Way
Step-by-step guides to troubleshoot certificate issues across real environments. No theory — just the commands and concepts engineers actually need.
