What’s the most common domain security mistake you keep seeing?

Lately I keep seeing the same issues over and over during security reviews:

weak or missing DMARC policies
broken SPF records
missing DNSSEC
expired SSL certificates
missing security headers
critical vulnerabilities that are often surprisingly easy to fix

The scary part is that many companies don t even realize these issues exist until deliverability, trust or security problems appear.
