at the Big Four

Two years and seven months. That's how long I lasted. In that time I experienced a Supply Chain Attack (Kaseya) and got up at two in the morning. Found out the customer was lucky — saved by an antivirus with a fairly simple but effective rule. Handled several ransomware attacks (Dark Side, Conti, and LockBit) — on weekends and through the night. As far as I know none of the affected organisations made the press, so we did our job well. I was part of the Czech team that finished 3rd at Locked Shields. I spoke at several conferences and universities. Gave a few interviews to newspapers (Deník N and HN), and was invited onto several podcasts.

Thanks for the opportunity.
