Universities with an expired security.txt in Sweden
5 universities in Sweden (13.5% of the 37 in the census list) lack security.txt Expires line (RFC 9116) as of 2026-09-30. Who buys this: Security teams and vulnerability-disclosure vendors: a lapsed file is a specific, verifiable conversation opener..
A security.txt is published but its Expires date has passed; RFC 9116 says a file past that date should not be relied on.
