ProSec, founded in 2016 and headquartered in Koblenz with additional offices in Berlin and Munich, is a German IT security firm built by people embedded in the hacker scene. The team of over 30 specialists operates independently - experienced penetration testers and management consultants who refuse engagements that might paper over real risk. That's not a marketing line; it's an operational filter that shapes what they actually sell.
The core offering is the Holistic Security Assessment: technical penetration testing, social engineering campaigns, and physical security evaluations rolled into a single engagement designed to simulate how a real adversary would move through an organization. The numbers are specific - more than 900 assessments completed, with a 100% compromise rate on penetration tests. That last figure deserves unpacking: it means every targeted system was breached, which tells you as much about the state of enterprise defenses as it does about their methodology.
Beyond offensive operations, ProSec handles ISO 27001 certification support and general IT security consulting for clients ranging from SMEs to critical infrastructure operators. Their Ethical Hacker Training programs have produced hundreds of certified professionals. The work spans three domains - digital, human, and physical - and the team's refusal to give false assurances suggests a shop where technical accuracy matters more than deal volume.
