DISK

What DISK does

DISK (Deutsches Institut für Sicherheit und Krisenvorsorge) is a Hamburg-based, privately held crisis management and organizational resilience consulting firm, incorporated in 2022 as a UG (haftungsbeschränkt) with eight employees. The firm advises municipalities (Gebietskörperschaften), businesses (Unternehmen), and government authorities (Behörden) on preparing for and managing crises ranging from cyberattacks and natural disasters to energy crises, pandemics, supply-chain disruptions, and economic crime.

DISK's core offering is the proprietary four-tier Resilienzmodell nach Kerstan & Röhl — a consulting methodology dividing organizational resilience into Nano-Resilienz (risk management maturity), Mikro-Resilienz (emergency management), Meso-Resilienz (crisis and continuity management), and Makro-Resilienz (inter-organizational cooperation). The firm complements this with the seven-step Municipal Impact Analysis (MIA) method, which adapts Business Impact Analysis for municipal ecosystems. Service delivery is direct consulting engagement rather than productized software; deliverables include risk assessments, emergency plan evaluation, crisis staff training, continuity planning, and inter-organizational cooperation design.

DISK monetizes through professional services fees, with quote-based pricing tailored to each engagement and no publicly disclosed rate cards. Revenue streams span resilience consulting, training and education, and research publications. Go-to-market is sales-led and heavily reliant on thought leadership — academic working papers, conference appearances, and contributions to industry journals such as 'der gemeinderat', 'Sicherheitsdienst', and 'Protector' — combined with association partnerships (ASW, BDSW). The firm was co-founded by Tobias Walter (Geschäftsführer, ex-military/security leadership), Prof. Dr. André Röhl (Wissenschaftlicher Leiter, NBS Northern Business School), Rico Kerstan (Krisensicher Risikoberatung), Thorsten Bossel (Initiative KRITIS), and Mirko Schönfeldt (Baltic FS).

Direct peers

• Crisis24 (GardaWorld): Critical event management and crisis-response firm serving multinational clients with intelligence, travel risk, and incident response. Comparable in delivering integrated crisis preparedness and response services to enterprise and government buyers.
• S-RM: Resilience and crisis-management advisory firm offering preparedness, response, and recovery services to corporates and governments. Highly comparable service scope (risk, crisis, continuity) to DISK's four-tier model.
• F24: Munich-headquartered provider of critical communications and crisis-management SaaS for Europe. Comparable Germany/DACH presence and overlapping buyer base of KRITIS operators and large enterprises needing crisis response capabilities.

Broad incumbents

• PwC Crisis and Resilience: Big Four advisory practice offering crisis management, BCM, and operational resilience services. Competes for the same enterprise and public-sector engagements as DISK but as part of a much broader risk and audit portfolio.
