What happened —
and what did not.

The hardest thing to measure in security is what did not happen. The authority that did not go down, the document that did not leak, the production line that did not stop. Every incident here is real and published with the customer’s consent; identifying details were changed, and the timings are as recorded.

Three incidents

Three incidents, three outcomes.

Local authority

Ransomware stopped before it spread
