Why Check TLS for nih.gov?

TLS (Transport Layer Security) encrypts data in transit between your browser and nih.gov. Older protocols like TLS 1.0 and 1.1 have known vulnerabilities and are deprecated by major browsers. Our TLS checker tests which protocol versions nih.gov supports, identifies the preferred cipher suites, and assigns a security grade. Ensuring nih.gov supports TLS 1.2 or 1.3 is critical for protecting user data and maintaining compliance with modern security standards like PCI DSS.
