Solitaire Advisory Gmbh

What Solitaire Advisory Gmbh does

Solitaire Advisory GmbH is a Berlin-based cyber-physical security consulting firm founded on October 1, 2021, by Dr. Christoph U. Eichel, a former Bundeswehr officer and diplomat at the German Embassy in Afghanistan. The firm delivers an integrated advisory portfolio combining physical security for people, assets, and buildings with cyber defense for IT and OT infrastructure under what it describes as an 'asymmetric security' methodology, positioning itself as the first mover in the German market for this combined offering. Services span cyber security consulting (ISO 27001 and BSI IT-Grundschutz alignment, NIS/NIS2 audits, OT/IIoT security, EU Cyber Resilience Act support), physical security (personal protection, threat intelligence, travel and project security), risk and crisis management (ISO 22301 business continuity, kidnapping and extortion response, evacuation support), and OSINT/HUMINT-based investigations and due diligence. Revenue is generated through professional services engagements quoted individually to clients, supplemented by training revenue through the in-house Solitaire Academy distributed via the Swiss Evrlearn platform.

The firm serves the German Mittelstand as its primary segment, alongside publicly traded enterprises, NGOs operating in complex environments, critical infrastructure operators (KRITIS), exposed individuals and families, and Bundeswehr/BOS security authorities. Go-to-market relies on enterprise field sales led directly by senior leadership including the CEO, with a 24-hour response commitment and consultative scoping. Geographic coverage is delivered through 14 offices: Berlin headquarters at Pariser Platz 6a, four additional German offices in Cologne, Frankfurt, Hamburg, and Munich, and international hubs in Bogotá, Hong Kong, Lagos, Manila, Nairobi, Paris, Riyadh, São Paulo, and Syria (since December 2024).

The team is drawn from German and allied security authorities, with leadership including former Bundeswehr officers, Cyberagentur alumni, an ex-German Embassy Afghanistan diplomat, and a Danish Air Force captain and former Danish Ministry of Foreign Affairs crisis advisor. The company is founder-owned with no disclosed venture or private equity backing, reports 11-50 employees, and discloses no public revenue figures. Distribution is reinforced by partnerships with BITKOM, the Allianz für Cyber-Sicherheit, AMENA Africa, BVMW, Evrlearn, Safeture, and DEKRA, plus active participation as speaker and exhibitor at security industry conferences.

Core offering

Solitaire Advisory provides integrated cyber-physical security consulting that combines physical security for people, assets, and buildings with digital IT infrastructure protection. The company delivers three core service pillars — Cyber Security Services (information security, OT/IIoT security, NIS2 compliance), Physical Security Services (security strategy, travel security, personal protection), and Risk and Crisis Management (business continuity, kidnapping/extortion protection, evacuation) — alongside its proprietary Solitaire Academy training division.

Product overview

Solitaire Advisory GmbH is a cyber-physical security consulting firm that offers an integrated portfolio of advisory and training services under its own brand. The core offering is built around three pillars: Cyber Security Services (covering organizational strategy, information security, security audits, OT/IIoT security, and secure product development), Physical Security Services (covering security strategy, prevention training, travel security, threat intelligence, and personal protection), and Risk and Crisis Management (covering business continuity, kidnapping/extortion protection, crisis communication, and evacuation). These consulting services are supplemented by a proprietary training division, Solitaire Academy, which delivers courses in cyber security, security management, and operational security. The company also organizes its expertise into three focus solutions: 'Sicherer Mittelstand' for SME security, 'Cyber Resilience for Deep Tech' for high-tech companies, and 'Security for Critical Infrastructures and OT/ICS' for operators of critical infrastructure. All services are delivered by a team of security experts, many with backgrounds in government security agencies, and supported by a global network of offices.
