48 banks in Iowa (21.6% of the 222 in the census list) lack HTTP Strict Transport Security header as of 2026-09-30. Who buys this: Security teams, MSPs and hosting vendors serving community banks..
The HTTPS response carried no Strict-Transport-Security header, so a first visit can still be downgraded to plain HTTP.
