CipherSentinel – Continuous TLS & Security Header Auditor Detailed Description What CipherSentinel Does? CipherSentinel plugs straight into Chrome DevTools and continuously inspects every HTTPS request your page makes. It captures: TLS protocol & cipher suite in use (with alerts for outdated protocols or weak ciphers) Certificate details (issuer, validity dates, RSA key length) and countdowns to expiration Critical security headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options) Threat advisories by cross-referencing ciphers against known CVEs All of this data is presented in a live, filterable table—no manual scans, no external services.
