Who we are

Our team of 40 PCI auditors is as diverse as our clients: We advise companies worldwide in twelve languages and certify them according to the security standards of the Payment Card Industry. As a centrally organized team that is in constant professional exchange with around 180 usd security experts, we deliver first-class results from a single source. The successful completion of your certification project is our top priority.

Since 2018, we have supported the PCI Security Standards Council (PCI SSC) as a strategic partner in the Global Executive Assessor Roundtable (GEAR) with our industry-specific, geographic and technical knowledge.

Christopher Kristes
Head of Security Audits & PCI

„Our clients appreciate us for our pragmatic way, our helpfulness and our view on reality. With our many years of experience, we accompany our clients worldwide as an independent consultant and auditor to a successful PCI certification.“

Nicolas Schiller
Managing Consultant

„As a PCI auditor, it is important for me not to leave my clients alone when the assessment reveals deviations from the security standard. In this case in particular, it is important to identify, discuss and evaluate pragmatic solutions. For me, this is what defines a trusting relationship.“

Julia Wingert
Senior Consultant

„I accompany certification projects of merchants across national borders as a PCI DSS auditor. No environment and no process is the same. Maintaining an overview and finding a suitable solution for complex contexts is challenging, but also great fun for me.“

Torsten Schlotmann
Head of PCI Security Services

„The security of software products is one of my main focuses. Every certification project in this field is unique, as processes, technologies and application areas differ. Therefore, a solution-oriented and partnership-based cooperation with my clients is particularly important to me.“

Manfred Ferstl
Managing Consultant

„I have been advising companies on IT security issues for many years. A current practical example are cashless payments at gas stations or in supermarkets. As a PCI PIN Assessor, I work with our clients to find the best solution for protecting their customers’ PIN.“
