RedMimicry Secures Funds To Advance Its Cyberattack Emulation Platform

The funding was led by High-Tech Gründerfonds (HTGF), with participation from Capital Square, Munich-based superangels and other private investors.

Franzi Majer, Founding Partner at superangels, says, “We’re excited to back RedMimicry, whose realistic cyberattack simulations help companies uncover vulnerabilities before attackers do. Their technical excellence, market relevance and visionary team make them exactly the kind of startup we love to support.”

RedMimicry offers a platform that lets organizations run repeatable cyber-attack simulations to test and strengthen their defenses. Many firms conduct only limited testing, leaving gaps in processes, technology, and collaboration. With regulations like DORA and NIS-2 mandating comprehensive security tests, RedMimicry helps validate systems against malware, intrusions, and other scenarios while managing cost and effort.

The platform serves enterprises, managed security service providers, and consulting firms, and supports partners in improving security processes. Founded in 2023 by Alexander Rausch and Stefan Steinberg, the team draws on experience from Proofpoint and the German Cyber Security Organisation (DCSO).

Björn Sykora, Principal at HTGF, mentions, “Alex and Stefan combine technical excellence with entrepreneurial vision. With RedMimicry, they are addressing one of the greatest risks companies are currently facing: protection against cyber-attacks. They provide a European security solution that benefits both medium-sized and large companies.”

The funding will enable RedMimicry to enhance its platform, focusing on threat scenarios targeting critical infrastructure (OT) and financial services. The company will also grow its sales team and broaden its partner network.

Alexander Rausch, founder and CEO of RedMimicry, says, “Our vision is to enable companies to protect themselves independently and effectively against increasingly complex cyber-attacks. With the support of experienced investors, we can advance our technology significantly and expand our market position.”

Martin Ostermayer co-founder of Capital Square adds “We’re excited to back RedMimicry as they revolutionise how companies prepare for and defend against sophisticated cyberattacks. Their bold vision and outstanding team embody exactly the kind of ambition and expertise we look for in founders and we’re confident they’ll set new standards in cybersecurity.”
