Priority fixes for tossinvest.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
DMARC policy enforces quarantine or reject
Observed: The DMARC policy for tossinvest.com 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.
58% of Stock & Crypto Trading peers do this. Limit: Read from public DNS at the time of the check; records may have changed since.
Priority 2 · Accelerate
Modern image formats in use
Observed: The homepage had 3 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.
48% of Stock & Crypto Trading peers do this.

Priority 3 · Enable
Page language declared
Observed: The homepage <html> element had no lang attribute.
What to do: Set lang on the html element (for example lang="en") and on any sections in another language.
93% of Stock & Crypto Trading peers do this.
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.
On Next.js: Next.js documents nonce-based CSP with middleware.
