Priority fixes for bvg.de
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
Certificate has more than 14 days left
Observed: The certificate from DigiCert Inc was due to expire on 2026-11-06 (14 days after the check).
Why it matters: An expired certificate makes browsers show a full-page warning. Renewing well ahead of expiry leaves time to fix a failed renewal.
What to do: Automate renewal with ACME (for example Let's Encrypt or your CDN's managed certificates) and add a renewal review to your release calendar so any certificate inside 21 days of expiry gets attention.
98% of Trains & Public Transport peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.
Priority 2 · Harden
DMARC policy enforces quarantine or reject
Observed: The DMARC policy for bvg.de was p=none, which asks receivers to take no action on failing mail.
What to do: Publish DMARC with p=none and a reporting address first, fix any legitimate senders that fail SPF or DKIM alignment, then move to quarantine and finally reject.
40% of Trains & Public Transport peers do this.
Priority 3 · Accelerate
Modern image formats in use
Observed: The homepage had 26 images and none used WebP or AVIF.
What to do: Serve WebP or AVIF with a JPEG or PNG fallback, either through an image CDN or by generating both formats at build time.
On Next.js: The next/image component serves optimized formats automatically.
28% of Trains & Public Transport peers do this.
Guide: AVIF, WebP, JPEG, and PNG: Choose the Right Image Format
Priority 4 · Accelerate
HTTP/3 advertised
Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.
What to do: Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.
28% of Trains & Public Transport peers do this.
