Access your industrial equipment from anywhere.
VPN connection secured by hardware key
Authentication relies on a physical key, not a password. Each login is tracked: who accesses, when, and to what. Compliant with the highest OT/IT requirements.
Operational in a few minutes
No firewall rules to reconfigure, no complex VPN to deploy. Tosi works behind NAT, over Ethernet, Wi-Fi, 4G or 5G.
Remote or local access
Operate your equipment from the office, while traveling, or from a service provider. The connection remains stable even in case of a network outage.
Usage via Cloud or On Premise
Host the solution on your own infrastructure. No process data leaves your network.
What you need
The security key of Tosi
The personal and secure access point. Plug it in to authenticate yourself on your private VPN network.
Without it, no access is possible: it's your material identity.
The bridge (Tosi LOCK)
Installed on the equipment side, it creates the encrypted tunnel between your workstation and your machines. Available in Ethernet, Wi-Fi, 4G, and 5G versions depending on your field environment
Optionally, the centralized management platform (Tosi HUB)
Monitor all your access, manage rights by user or by site, and view login logs from a single interface.
Use Case
Remote Internal Maintenance
A technician from the company connects from their office to the controller of a remote production line without any travel.
External contractor intervention
A subcontractor accesses an automation during a defined window, with complete traceability of the session.
