Tosi, formerly TOSIBOX, is a Finnish platform for secure remote access and network security in operational technology (OT) environments. According to its website it is an integrated hardware and software platform offering secure remote access, asset visibility, network security with anomaly detection and support for compliance. The company presents itself as Tosi on its website, while its product line still carries TOSIBOX names such as TOSIBOX Key and HUB. The hardware components are intended for deployment in the customer's network.
According to the website, the company's global headquarters is in Oulu, Finland; the site also lists a US location in Irving, Texas. The website does not describe where data is stored or whether cloud components exist. Because the hardware and software are deployed on the customer's own network, the core access path can remain within the organisation's network. For a European organisation this means a vendor headquartered in Finland for OT remote access, although ownership, support arrangements and any cloud services should still be checked.
