Unboxed For You
Secure OT connectivity, visibility, and control from one scalable platform.
Tosi Selection GuidesThe Tosi Platform
The Tosi Platform combines industrial-grade hardware and cloud-based software to help solve the challenges created by sprawling OT environments. Tosi Gateways create encrypted tunnels at remote sites without network changes, users connect through Tosi Keys or software Clients, Tosi Hub scales connectivity across large deployments, and Tosi Control provides centralized visibility and management.
Why Tosi Is Different
Tosi is designed to simplify secure OT connectivity while giving your team more control as the environment grows.

Automated, Fast Deployment
Tosi Gateways create encrypted connectivity without requiring static IP addresses or firewall changes, helping teams deploy secure OT access in minutes.

Enterprise-Grade Security
The platform uses zero-trust architecture, AES-256 end-to-end encryption, outbound-only connections, identity-based access controls, and no open inbound ports. Tosi is ISO/IEC 27001:2022 certified.

Your Data Stays Yours
Tosi states that enterprise-grade encryption protects your data at every step and that it does not access or store your operational data.
