Priority fixes for lightpdf.com

Ordered by impact and by how common each practice is among peers.

  1. Priority 1 · Harden

    HSTS kept for at least a year

    Observed: The homepage response did not include a Strict-Transport-Security header.

    Why it matters: HSTS tells browsers to use HTTPS for your host on every later visit, which removes the window where a first HTTP request can be intercepted.

    What to do: Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.

    On Cloudflare: Enable HSTS under SSL/TLS > Edge Certificates > HTTP Strict Transport Security and raise max-age gradually.

    30% of Web Tools peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

  2. Priority 2 · Harden

    DMARC policy enforces quarantine or reject

    Observed: The DMARC policy for lightpdf.com 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.

    23% of Web Tools peers do this.

  3. Priority 3 · Harden

    X-Content-Type-Options: nosniff

    Observed: The homepage response did not include X-Content-Type-Options: nosniff.

    What to do: Send X-Content-Type-Options: nosniff on all responses and make sure each file is served with the correct Content-Type.

    On Cloudflare: Add the header with a response header transform rule.

    44% of Web Tools peers do this.

  4. Priority 4 · Harden

    Content Security Policy present

    Observed: The homepage response did not include a Content-Security-Policy header.

    What to do: Start with Content-Security-Policy-Report-Only to see what would break, tighten the policy over a few weeks, then enforce it.

    15% of Web Tools peers do this.
