    "Lengow does not have a bug bounty/reward program and will therefore not offer paid bug/security
    rewards. We might however offer a token of our appreciation to security researchers who take the
    time and effort to investigate and report security vulnerabilities to us." — Lengow Security Team,
    verbatim from the served security.txt

note: >-
  Lengow serves a real RFC 9116 security.txt from two hosts, with a named security contact, a PGP key
  location and an explicit bug-bounty posture. Two gaps: the `Expires` value is 2023-09-08, so the
  document is stale by RFC 9116's own rule, and there is no `Policy:` field pointing at a disclosure
  policy page (/security and /security/responsible-disclosure both 404 on www.lengow.com). Refreshing
  Expires and adding a Policy URL is the cheapest fix available to this provider.
