HiSolutions

HiSolutions AG is one of Germany's most established cybersecurity consultancies, headquartered in Berlin with additional offices in Bonn, Frankfurt, and Nuremberg. Founded in 1992, the firm has spent more than three decades advising German federal agencies, DAX-listed corporations, and critical national infrastructure operators on information security, risk management, and offensive security testing. HiSolutions holds a particularly strong reputation for BSI IT-Grundschutz implementation, and is one of a small number of providers recognised by the Bundesamt für Sicherheit in der Informationstechnik (BSI) for its assurance work across the German public sector.

The company's penetration testing practice delivers web application, network, cloud, mobile, and Active Directory assessments alongside red teaming, purple teaming, and source code review. HiSolutions methodologies align with BSI standards, OWASP, OSSTMM, and PTES, with engagements typically scoped to satisfy the combined demands of NIS 2, the EU Cyber Resilience Act (CRA), and DORA. The firm is well known for running the German-language "Security Summit" conference and for publishing detailed technical advisories through its research arm.

HiSolutions is best suited to German and DACH-region enterprises that need a local-language consultancy with deep regulatory fluency. Clients include federal ministries, state-level IT service providers, automotive manufacturers, energy utilities, and hospital groups, organisations where Germany-specific compliance and on-site German-speaking consultants are non-negotiable.
