Compliance and Security at Unzer

Why Merchants can trust us

Anyone who processes payments bears responsibility—for the data of their merchants, for the data of end customers, and for the integrity of every single transaction. At Unzer, security is not a feature that can be added on. It is the foundation on which we have built our entire platform.

Our certifications at one glance

PCI-DSS Level 1

All card payments are processed according to the strictest international security requirements.

ISO 27001

Information security is systematically embedded at Unzer, with clear processes, regular audits, and continuous improvement.

ISO 37301

Our compliance structures meet the highest international standards, independently verified.

Maximum Security in Payment Processing

Unzer holds not just one but three licenses as a payment institution: in Germany, Luxembourg, and Denmark. This means we are regulated by three different financial supervisory authorities. As a result, we undergo regular audits and continuously demonstrate that our capital requirements, risk management, and compliance processes meet all legal standards.

24/7 Fraud Monitoring & AI-Powered Risk Detection

A dedicated security team monitors all activities on the platform around the clock. Our AI-powered risk platform also analyzes transaction patterns in real time, detecting suspicious activity before it can cause harm. As a merchant, you don't need manual monitoring or your own risk department—we handle this completely in the background for you.

Data Protection to European Standards

As a European payment service provider, Unzer is fully subject to the General Data Protection Regulation (GDPR) and continuously invests in its data protection processes and technical safeguards. For you as a merchant in Germany and the DACH region, this means: responsibility stays right where your business is at home—in Europe.
