Banks without a security.txt in Iowa
216 banks in Iowa (97.3% of the 222 in the census list) lack security.txt (RFC 9116) as of 2026-09-30. Who buys this: Security teams, vulnerability-disclosure and attack-surface vendors, fintech and MSP vendors selling to community banks..
No security.txt was found at /.well-known/security.txt or /security.txt on the final host, so a researcher who finds a vulnerability has no published contact.
