Ringkasan laporan

dtu.dk currently holds an SSL grade of B (80/100) from CertH TLS health monitoring. The site supports TLS1.3, TLS1.2, does not enable HSTS, and its certificate is issued by GEANT TLS RSA 1 — 10 days left on the certificate. CertH records daily TLS handshake probes into an auditable certificate health trend.

Perlu perbaikan — Masalah yang bisa diperbaiki: masih mendukung TLS 1.1, tanpa HSTS, atau tanpa PFS.

dtu.dk mendapat skor lebih tinggi dari 10% dari 12,269 situs yang dinilai.
