Any business that collects customer information, runs an online platform, or operates across borders eventually asks the same question: does Kenyan law apply here, does GDPR apply, or does both apply at once? For companies based in Nairobi with European clients, or multinationals with Kenyan subsidiaries, this is not a hypothetical concern. It shapes contracts, privacy notices, breach response plans, and even how quickly a company must react when something goes wrong. Kenya's Data Protection Act, 2019 (DPA) was deliberately modeled on the European Union's General Data Protection Regulation (GDPR), so the two frameworks share a lot of DNA. But they are not identical, and the differences matter in practice. Below is a detailed, practical comparison covering scope, data subject rights, breach notification timelines, and penalties, along with what dual compliance actually looks like for businesses operating under both laws.
