>cat bio.txt — Who is Sven Kellig?
Sven Kellig is an intelligence (INT) specialist based in Brussels, where he advises European institutions and regulated organisations on the intersection of intelligence practice, data protection and EU compliance law.
His work centres on the intelligence cycle end to end — collection planning, source validation, structured analytic technique and the disciplined reporting that turns raw signal into decisions that hold up under scrutiny. He is equally at home with open source (OSINT) collection at scale and with the legal limits that govern it inside the Union.
At PRÜFUNG he leads assessments that trace where European data actually goes: mapping cross-border transfers, identifying unauthorised exports to non-EU jurisdictions, and exposing the third-party dependencies that quietly place citizens' records outside the reach of EU law. That combination — an intelligence analyst's tradecraft applied to a compliance problem — is the core of his practice.
He writes and briefs on counter-intelligence exposure in commercial supply chains, foreign-state access to cloud infrastructure, and how GDPR obligations translate into operational controls rather than paperwork.
