Stein Columna Consulting Limited
Specialist legal, data protection, and compliance advisory for corporate and institutional clients, with particular focus on Zambia's evolving legislative environment and comparable legislation across the region.
About
Built on standing. Guided by principle.
Stein Columna is a Zambian regulatory affairs, data protection, and governance group serving corporate and institutional clients across Southern Africa. We bring legal rigour, multi-jurisdictional experience, board-level governance depth and a principled view of privacy to a market where qualified expertise is urgently needed and still scarce.
Who We Are
Specialist standing, a single standard.
Established in 2026 and based in Lusaka, Stein Columna works to a clear standard of rigour.
Our Conviction
Privacy is a human right before it is a regulation.
Long before data protection became law, our founder spent six years as a human rights advocate, directing what was then the only litigation-based refugee programme in Africa.
That work shaped a conviction at the centre of everything we do: protecting personal data is, at its core, protecting people - their dignity, their autonomy, and their safety.
The result is not paperwork for its own sake, but systems that earn trust and hold up to scrutiny.
