Test Results Summary for optimum.com

• Post-Quantum Cryptography (PQC) Readiness Test
  The server on the tested port is currently not prepared for post-quantum key exchange. The server’s certificate chain relies entirely on classical signature algorithms without post-quantum support. Show details.
• SSL/TLS Certificate Analysis
  1 SSL/TLS end-entity certificate detected: the first certificate is a trusted RSA 2048 bits certificate with issuer Sectigo Public Server Authentication CA OV R36 valid until May 16, 2027. 1 certificate chain detected. Show details.
• PCI DSS Compliance Test
  16 of 31 supported cipher suites are not compliant with PCI DSS. The server supports only PCI DSS compliant protocols: TLSv1.2. The server supports PCI DSS compliant elliptic curves (P-384, P-521 and P-256) as well as non-compliant elliptic curves (secp256k1). There is 1 more issue which makes the server non-compliant with PCI DSS: potential Marvin Attack. Show details.
• NIST and HIPAA Compliance Test
  19 of 31 supported cipher suites are not compliant with HIPAA requirements (Ref. NIST SP 800-52). The server supports only HIPAA compliant protocols: TLSv1.2. The server supports HIPAA compliant elliptic curves (P-384, P-521 and P-256) as well as non-compliant elliptic curves (secp256k1). There are 3 more issues which make the server non-compliant with HIPAA: server does not support OCSP stapling, server does not support TLS 1.3, server does not support extended master sECret. Show details.
• Industry Best Practices Test
  2 issues related to industry best practices were identified: server does not support TLS 1.3, server does not have cipher preference. Show details.
