Exein develops an embedded, hardware-agnostic cybersecurity platform that integrates runtime security directly into device firmware, allowing connected devices to detect, contain and respond to threats even when offline. The system already safeguards more than 1.5 billion devices in sectors such as energy, healthcare, defence, automotive, aerospace and industrial automation, and the company projects this figure will surpass two billion in Q1 2026. Exein’s technology supports integrity checks across supply chains and helps manufacturers comply with regulations like RED 3.3, the forthcoming EU Cyber Resilience Act and the US Cyber Trust Mark. Looking ahead, the firm plans to release next-generation protections for on-device AI and large language models, with an initial unveiling slated for RSAC 2026. The new capital will also fund a multi-transaction M&A programme in 2026 and accelerate expansion in the US and APAC. Exein has experienced a significant valuation uplift since mid-2025, reflecting rising demand for device-level security and its strengthened commercial position.
