Most common issues

  1. No DMARC record — phishing using your domain is possible (seen 5x)
  2. No CAA records (seen 5x)
  3. DNSSEC not detected (seen 5x)
  4. No SPF record (seen 4x)
  5. No DMARC record (seen 4x)

What to do about it

If any of the above sounds familiar, the fix is usually quick: missing security headers and outdated front-end libraries are the two most common findings we see, and both are typically a same-day fix. Run a free Security Score scan to see where your own site stands.
