Tosi Lock and Tosi Key: Professional Secure Remote Access & IoT/OT Connectivity
The TOSIBOX® Lock series, together with TOSIBOX Keys, offers a reliable and user-friendly way to achieve secure remote access, industrial connectivity, and IoT/OT networking. Using patented Plug & Go™ technology, a secure VPN tunnel is created within minutes, without complicated network configuration, public IP requirements, or firewall expertise.
TOSIBOX Locks enable stable, encrypted, and scalable connectivity across a wide range of applications, including industrial automation, building management, energy, utilities, water systems, and smart-city infrastructures. Secure access to these networks is provided through TOSIBOX Keys, available as USB Keys and Soft Keys, which allow encrypted access to OT/SCADA environments.
Designed to work as a unified system, Locks and Keys support instant deployment without static IPs or complex certificate management, while enabling granular access control for precise permission handling. This makes the TOSIBOX solution ideal for remote maintenance, tele-service, partner access, and the secure management of distributed industrial infrastructures with minimal IT overhead.
TosiControl and Tosi HUB : Centralized Control & Scalable OT Network Management
TosiControl provides a unified, web-based interface for managing the entire OT environment — from gateways and Hubs to Keys and user roles. It offers real-time network topology, device monitoring, and access control, giving centralized visibility across distributed infrastructures. When combined with TOSI’s zero-trust industrial VPN platform, it enables secure, encrypted remote access to OT/SCADA systems and granular user permissions, making it well suited for industrial automation, remote maintenance, and multi-site management.
Building on this centralized control layer, TOSI HUB connects distributed industrial sites into a single, centrally managed OT network. As a software-only virtual solution, it supports hundreds to thousands of concurrent VPN connections — including Locks, Keys, and Mobile Clients — and enables secure, encrypted routing between all nodes. HUB can be deployed either on-premises or in cloud environments such as Azure and AWS.
With virtual LAN support, granular access group management through drag-and-drop configuration, continuous 24/7 monitoring, audit logging, and network segmentation, TOSI HUB reduces complexity while improving scalability and availability. Together with TosiControl, it simplifies deployment, lowers administrative overhead, and provides a robust foundation for remote maintenance, multi-site operations, and secure industrial automation.
