About Us

Pentagrid AG was founded in 2019 by Martin Schobert and Tobias Ospelt and is a boutique assessment and consulting company working in the information security sector. Before founding Pentagrid AG, Tobias and Martin worked both for a decade as IT security analysts for several customers, especially from the financial, medical, healthcare, and automotive sector.

Pentagrid is a neutral and independent security service provider. Neutral means we examine informations system and document what we see. We will not write reports tailored to support a product marketing. We feel strongly committed to a professional service with a focus on successful long-term relationships with our customers. As we believe transparency is important, we explain approaches, proposals and issues to our clients. We feel bound to confidentiality even without formal non-disclosure agreements. Furthermore, with our knowledge we feel responsible for the society and socities in foreign countries. Therefore, we will not participate in projects when we feel these to be incompatible with our values, which for example excludes projects for the military, the arms industry, and the intelligence apparatus.
