Priority fixes for reshutka.ru

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

1. Priority 1 · Harden

   DMARC policy enforces quarantine or reject

   Observed: The DMARC policy for reshutka.ru was p=none, which asks receivers to take no action on failing mail.

   Why it matters: An enforcing DMARC policy helps receiving mail systems reject email that falsely claims to come from your domain, a common route for phishing your customers.

   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.

   36% of Education & Online Learning peers do this. Limit: Read from public DNS at the time of the check; records may have changed since.

2. Priority 2 · Accelerate

   Modern image formats in use

   Observed: The homepage had 25 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.

   32% of Education & Online Learning peers do this.

3. Priority 3 · Accelerate

   Offscreen images lazy-loaded

   Observed: The homepage had 25 images and none used loading="lazy".

   What to do: Add loading="lazy" to images below the fold. Do not lazy-load the main hero image, because that delays the largest visible element.

   52% of Education & Online Learning peers do this.

4. Priority 4 · Harden

   Framing restricted

   Observed: The homepage did not send frame-ancestors or X-Frame-Options, so other sites may frame it.

   What to do: Send Content-Security-Policy: frame-ancestors 'self' (or a list of trusted origins). X-Frame-Options: SAMEORIGIN covers older browsers.

   49% of Education & Online Learning peers do this.
