CybExer Technologies is an Estonian cybersecurity company founded in 2016 that builds a proprietary cyber range platform used for realistic live-fire exercises, capture-the-flag competitions, vulnerability testing, and incident response validation. The platform supports both cloud-based SaaS (Cyber Range as a Service) and bespoke on-premise deployments, and is complemented by sub-products including the NATO Defence Innovation Award-winning Integrated Scoring and Awareness (ISA) visualization tool, STRATEX for strategic crisis simulations, Digital Twin technology for virtual system cloning, and a Skills Testing Platform mapped to the NICE framework. CybExer also develops a Space Cyber Range and an Active AI Defence Solution under Estonian government and European Defence Fund funding.
The company serves government and military organizations (Estonian Defence League, UK Army, Ukrainian Armed Forces, Portuguese Army, Luxembourg MoD, European Defence Agency), financial institutions (SEB, Swedbank, LHV, Coop Estonia), utilities (Neste, Eesti Energia), critical infrastructure operators, MSSPs, academia, and space sector clients, operating from offices in Estonia, the UK, Finland, Czech Republic, Latvia, and Poland with a customer footprint described across 30+ countries. Revenue is generated through usage-based SaaS subscriptions, one-time on-premise licenses, and professional services for exercise design, training delivery, and custom scenario development. Go-to-market combines direct enterprise field sales with a tiered channel partner program, supplemented by community-led growth through competitions such as Cyber Battle of Estonia and Hack the Isles. The company holds ISO 9001 and ISO 27001 certifications (2025) and has raised approximately €6.5 million to date across a €5 million Karma Ventures-led round (2022) and €1.5 million SEB Baltic Venture Debt facility (2025).
