KATARZYNA MATYJANKO
I specialise in privacy, information security and data management, particularly
in Finance and Tech. My work is grounded in education and experience across compliance, risk management and AI governance, helping people and organisations better understand modern threats and their technological context.
When the product team wants one thing, legal says another, and the CEO asks about business risk – you need someone who understands all three and can drive a decision. I bridge the gap between what is technically possible, legally permissible, and commercially viable.
4disclosure was created to promote better understanding of data governance, data protection and information security – in a clear and accessible way.
