About Perseus

Perseus Technologies GmbH, founded in September 2017, is a specialized provider of cybersecurity services tailored for small and medium-sized enterprises (SMEs). The company was established by Steffen Teske, Sven Weizenegger, and Inna Leontenkova with the vision of providing continuous IT security and data protection.

The company's core business revolves around a holistic, employee-centered approach to establishing a sustainable cybersecurity culture. Perseus offers a Security-as-a-Service solution that encompasses prevention, risk assessment, and emergency assistance. Its product suite includes 'Perseus Care' for employee awareness training, 'Perseus Check' for identifying security gaps, 'Perseus Alert' for 24/7 emergency response, and 'Perseus Dock', a central portal for all its services. This model is designed to protect companies from data loss and internet-based threats by addressing all phases of a potential cyberattack. Revenue is generated through this comprehensive service platform, which also includes offerings like cyber insurance and GDPR compliance training.

A significant milestone for Perseus was its acquisition by the HDI Group on February 1, 2020, becoming a wholly-owned subsidiary. This partnership enabled Perseus to integrate cyber insurance into its offerings, providing cybersecurity concepts and insurance from a single source. In December 2018, the company received the Digital Lighthouse Award from Google and Süddeutsche Zeitung for its innovative insurance products.
