Hi, I'm Tomasz Sielski
Enterprise IAM that survives contact with an audit
Identity architecture · Cloud security · Enterprise governance
Most IAM architects speak either business or technology fluently. I work in both — translating between CISO strategy and Conditional Access policy, between compliance requirements and engineering tickets, between what an organisation needs and what its identity platform actually does. It's the same instinct that had me taking things apart as a kid — just aimed at systems that matter more now.
20+ years. Hundreds of thousands of users. Advisory and consulting engagements — evenings, CET/CEST.
