Handsome Boys Computer Club

Handsome Boys Computer Club is a sole proprietorship (in Polish, jednoosobowa działalność gospodarcza) run by Jerzy Siwecki. It is registered in Poland, in the European Union, and has been active since 2022. Its tax number (NIP) is 7773185123.

The work is security engineering: detection and monitoring, incident response, threat intelligence and cloud security. This site is the part of the business that is given away. The notes, measurements and tools here are free to reuse; the client work stays off these pages, and so does anything about the lab as it actually runs.
