When was DeltaSecure founded?

DeltaSecure GmbH was founded in 2022. Managing Director Dominik Munsterer built the company after years as a senior consultant for SIEM and SOC projects at renowned organizations including Commerzbank, Airbus, KfW Banking Group, BWI, ADAC, Traton (MAN), ZF Friedrichshafen, and the BMI.

How large is the DeltaSecure team?

Currently 13 full-time employees, supplemented by a network of certified security specialists and partner companies for scalable projects. The focus is on senior consultants with years of hands-on experience. We consciously choose not to grow by staffing junior consultants.

Where are the offices located?

Main locations: Frankfurt am Main (Grosse Friedberger Str. 42, 60313) and Tettnang (Kathreinfelder Str. 18, 88069 -- registered office). Both locations are used for client and audit meetings; remote consulting throughout Germany, on-site deployments in DACH plus EU.

What differentiates DeltaSecure from other security providers?

(1) Senior-only policy: no junior consultants deployed at client sites. (2) Vendor independence: no commissions from SIEM/EDR vendors. (3) Results orientation: 100% TISAX success rate across all projects to date. (4) Made in Germany: all employees and data processing in Germany, no US CLOUD Act access.

What industry references does DeltaSecure have?

Major IT service provider (6,500+ employees, 140,000 PCs), energy provider & water utility (350+ employees, largest wind farms in Germany), regional energy provider (KRITIS, 23,000 households). Detailed reference discussions available under NDA -- many clients cannot be publicly named due to their exposed security posture.

What vision does DeltaSecure pursue?

A uniform, high level of security for the German economy -- especially for the mid-market as its supporting backbone. Cybersecurity should no longer be a question of company size or budget, but effectively and economically available to all organizations.
