Tosi

What Tosi does

Tosi (formerly Tosibox) is a Finland-headquartered operational technology (OT) cybersecurity and connectivity platform provider founded in 2011 in Oulu. The company delivers an integrated hardware-and-software platform purpose-built for OT environments, serving 800+ enterprise and mid-market customers across 40+ countries in verticals led by oil & gas and including water/wastewater, manufacturing, building automation, retail, financial services, real estate, education, and entertainment automation. At the core is Tosi Control, a cloud-based console for remote site connectivity, real-time asset monitoring, and access management, paired with Tosi Hub, Tosi Gateway, and Tosi Lock hardware and the patented Plug & Go™ deployment technology that the company says enables OT network connectivity in minutes rather than months without IT skills.

The platform is built on a zero-trust network architecture with cryptographic device authentication, physical key-based multi-factor authentication, encrypted tunnels presenting no visible attack surface, and role-based access control with time-based restrictions. TosiANTA (Advanced Network Traffic Analytics) and Tosi Insight provide behavioral network traffic analysis and anomaly detection with protocol-native understanding of Modbus, DNP3, and Profinet. TosiSIM provides cellular connectivity with automatic failover, and TosiCARE bundles tiered support, training, and professional services. The platform is ISO/IEC 27001:2022 certified, was recognized as a Representative Vendor in the February 2026 Gartner Market Guide for CPS Secure Remote Access, and has secured 14,000+ OT sites globally.

Tosi monetizes primarily through annual subscription agreements that bundle hardware devices and professional services, with disclosed deal sizes ranging from mid-five-figure to six-figure amounts (the EPIC Crude midstream agreement deploying 675 devices across an 800-mile Texas network is the largest disclosed). Go-to-market combines a direct enterprise field sales motion — strongest in North America after the US sales team was doubled in 2025 — with a network of 200+ channel and implementation partners spanning system integrators, technology providers, and resellers, including the Inductive Automation Ignition Technology Provider Program partnership. The September 2025 rebrand from Tosibox to Tosi marked a strategic repositioning from hardware vendor to Cyber Physical Systems platform provider, coinciding with a 70% increase in average subscription deal size in 2025. Reported FY2025 turnover is approximately $14M.

Revenue model

1. Subscription (Platform): Tosi Platform is sold on a subscription basis, with Tosi Control included in every subscription. Subscriptions cover connectivity, visibility, and security capabilities. The company reports 70% growth in average subscription deal size in 2025, and its largest subscription agreement to date was signed with EPIC Crude. Deal structures include professional services bundled with device deployments (e.g., 675 devices + TosiSIM + professional services for EPIC Crude).
2. Hardware (Devices): OT-ready hardware products including Tosi Hub, Tosi Gateway, Tosi Lock, and Tosi Client devices are sold as part of comprehensive OT network solutions. Device sales are typically bundled within subscription agreements rather than sold standalone.
3. Professional Services: TosiCARE services including tiered support, training, and professional services accelerate adoption. Professional services were explicitly included in the EPIC Crude deal, covering deployment and ongoing management of OT network infrastructure.
