RedMimicry

RedMimicry (RedMimicry GmbH) is a Berlin-based breach and attack simulation (BAS) startup founded in 2023 by Alexander Rausch (CEO) and Stefan Steinberg (COO). Its platform runs continuously updated, realistic adversary and malware emulation scenarios — described on its site as “Threat Signals” for SIEM/EDR validation and “Playbooks” for full attack-chain scenarios — plus an AI-assisted red-teaming capability that lets operators direct deployed implants in plain language. The goal is to let security teams validate whether their detection and response stack actually catches the tactics, techniques, and procedures (TTPs) of real-world threat actors, rather than relying on checklist-based assessments.

In August 2025 the company closed a seven-figure seed financing round led by High-Tech Gründerfonds (HTGF), with participation from Capital Square (Hamburg), superangels (Munich), and several business angels. RedMimicry is a member of Bitkom and TeleTrusT and has stated a go-to-market focus on critical infrastructure/OT and the financial sector. The company is confirmed actively operating as of this research: its public site lists a current product version history (e.g., a v1.1.7 release in mid-2026) and planned participation at it-sa 2026, a major European IT security trade show, indicating a live, maintained product rather than a dormant funding-database entry.

For CISOs, continuous, realistic BAS testing offers a way to validate detection coverage against current threat-actor behavior rather than point-in-time penetration tests. Public evidence of named enterprise customers is limited (the site references partner/channel relationships such as DCSO, SITS, and SRLabs more prominently than direct enterprise end-customers), and the company is very early-stage (single seed round, small core team), so adoption and independent efficacy evidence should be treated as nascent.
