School districts without a security.txt in Illinois
420 school districts in Illinois (49.8% of the 844 in the census list) lack security.txt (RFC 9116) as of 2026-09-30. Who buys this: Security teams, K-12 cybersecurity vendors and MSPs, district website vendors..
No security.txt at either location on the final host. Most district sites run on a few website vendors and a vendor-supplied file counts as published, so this list is largely districts whose website platform publishes none.
