What this gap means
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.
Control: security.txt (RFC 9116). Rule: no_security_txt over the census record (reachable sites only). Who buys this: Security teams, vulnerability-disclosure and attack-surface vendors, MSPs serving higher education.
The obligation it maps to
Vulnerability disclosure: security.txt (RFC 9116): RFC 9116 defines /.well-known/security.txt so researchers can find a contact and a policy; many national cyber agencies and the higher-education ISACs recommend it. Source

Atom feed: universities that entered or left this list according to the live re-checks (every 6 hours a rotating slice, each domain at most once per 14 days; each entry says which way it moved and which field changed). no-security-txt.top.json: the first 50 rows and the counts by country as JSON, CORS open. Fields watched: security_txt.
Membership reflects the homepage and well-known files as fetched on 2026-09-30: a control that exists but was not found where the census looked counts as missing, and sites answering 403 to our one polite request count as reachable. Every domain links to its record with what to fix, a JSON twin, a badge and a changes feed. Data licence CC BY 4.0. Not legal advice.
