 "honest_knock": "Note on how we link this one, updated 28 Jul 2026: between 21 and 28 July our partner link was dead: Tenable's shop subdomain stopped resolving, so we pointed the link at Tenable's own product page and earned nothing from it. Tenable confirmed on 28 July that the links are repaired; we re-tested them that day and the link now works again, lands on the same Nessus product page, and does pay us a commission. This is serious, enterprise-grade security tooling with an enterprise price and a learning curve, not a set-and-forget scanner. You need someone who can act on the findings, or you're paying for reports nobody reads.",
