Perseus

Perseus Technologies was founded in 2017 in Berlin to solve a specific gap in the German market: small and mid-sized enterprises (the Mittelstand) that face real cyber risk but lack the budget or staff to build an in-house security program. Rather than selling point tools, Perseus packages prevention measures, standardized cyber-risk assessments, and 24/7 emergency incident response into a single subscription-style service aimed at organizations that would otherwise have no dedicated security function at all.

The company’s go-to-market is unusual and worth understanding on its own terms: Perseus is majority-owned by insurance investors — HDI (part of the Talanx group) since a 2020 acquisition, specialty insurer Markel, and, as of 2025, SIGNAL IDUNA as an additional strategic investor. These insurers embed Perseus’s prevention and incident-response services into their own cyber insurance products, using Perseus as the risk-reduction and claims-response engine behind policies they underwrite. Perseus itself is not an insurance underwriter; it is the operational security service that insurers plug in to reduce claims frequency and severity for SME policyholders.

That distribution model has both an upside and a limit. The upside is reach: bundling security services with insurance is an effective way to get real protection in front of SMEs who would never independently shop for a standalone security vendor. The limit is that most of the public evidence available is about the company’s insurance-industry partners and investors rather than named end-customer outcomes, so the actual on-the-ground efficacy of its prevention and incident-response work is harder to verify independently than the business relationships around it.
