Why a European-only firm matters

Most audit firms treat European regulation as an add-on practice inside a much larger global business — useful for a rubber stamp, less useful when NIS2's incident-reporting clock starts at 24 hours.

Zulon Audits was built the other way round: European regulation is the entire business, not a service line. That's the difference between a firm that knows the EU AI Act exists and one that can tell you, this week, whether your product is classified as high-risk.

Built in Estonia, working across the EU

Estonia runs its government on the same digital-infrastructure principles we audit our clients against — e-residency, e-signatures, a fully digital company registry.

We didn't pick Tallinn for the tax treaty. We picked it because it's the one EU country that has already proven the model works at national scale.
