I’m Daniel Krol.
Information Security Officer at PKP PLK S.A. One of Poland’s largest railway operators. 10+ years protecting critical infrastructure.
On the side, I help companies find what their AI tools are leaking and fix it before it becomes a headline.
Why I do this
Most security advice is generic. “Use MFA. Train your staff. Update your policies.” Fine. But it doesn’t tell you what’s actually happening inside your organization right now.
AI tools changed that. ChatGPT, Copilot, Gemini. Your team is using them with real data, right now, outside your security perimeter. Most companies have no idea what’s leaving.
I find it. I map it. I tell you exactly what to do about it.
How I think
My top CliftonStrengths: Learner · Input · Analytical · Focus · Belief.
In practice: I track what’s happening in AI and cybersecurity obsessively, connect dots others miss, and don’t stop until I have a specific answer. Not a generic framework.
