TLS security monitoring explained
What it is
TLS (Transport Layer Security) encrypts data between the browser and your server. TLS security monitoring means checking that your site uses strong protocols (TLS 1.2 or 1.3), secure cipher suites, and a valid certificate that is not expired or misconfigured.
Why it matters
Weak TLS (e.g. TLS 1.0/1.1, weak ciphers) can be exploited to intercept or tamper with traffic. Expired or invalid certificates cause browser warnings and break trust. Monitoring TLS helps you catch misconfigurations and certificate expiry before they become incidents.
How Barrion checks it
Barrion runs passive TLS checks: we connect to your HTTPS endpoint and verify protocol support, cipher suites, certificate validity and hostname match, and certificate chain. We report deprecated protocols, weak ciphers, and expiry. All checks are read-only and production-safe.
