Tosi Hub Overview

Tosi Hub is the secure, scalable engine that powers your OT network. As a software-only VPN concentrator, Hub serves as the central connection point for your entire Tosi deployment, routing encrypted data, maintaining persistent connections, and enforcing network segmentation. Because it is virtual, Hub can be deployed in your office network or in leading cloud services like AWS or Azure.

What Tosi Hub Does

Hub makes your network work. It establishes and manages encrypted network connections across your distributed sites, creating a controlled OT network of always-on VPN connections for remote maintenance, continuous monitoring, real-time data collection, and data logging. Hub connects up to 1,000 Gateways and Clients concurrently, making it ideal for large distributed networks, data sovereignty requirements, and enterprise-scale operations.

How Hub and Tosi Control Work Together

Hub and Tosi Control are complementary components of the Tosi Platform, not an either/or choice. Tosi Hub is the engine that physically connects your sites and routes data. Tosi Control is the dashboard where you configure and monitor that engine. Together, they form the backbone for connecting, protecting, and controlling your entire OT environment. You need both for enterprise OT network management.

Core Capabilities

• Encrypted Data Routing: Creates encrypted VPN tunnels and is protocol-agnostic for traffic passing through. Your applications can use any protocol including SCADA, Modbus, OPC, HTTP, and more.

• Persistent Connections: Maintains always-on VPN connections for continuous remote access without requiring manual reconnection.

• Network Segmentation: Enforces network segmentation to isolate and protect critical OT systems. A single Hub can handle multiple customer networks through segmentation.

• Enterprise Scale: Connects up to 1,000 Gateways and Clients concurrently. The actual maximum depends on your license tier and the performance of your hosting hardware or platform.

• High Availability: Deploy multiple Hubs for redundancy. The architecture supports failover configurations to ensure high availability for mission-critical operations.

• Integrations: Supports Prometheus metrics and log forwarding for integration with existing monitoring infrastructure.

Deployment Options

Hub is software-only and integrates with your existing virtualization or cloud infrastructure:

• VMware

• Hyper-V

• KVM

• Microsoft Azure

• Amazon Web Services (AWS)

Security and Compliance

Hub provides enterprise-grade security for OT environments:

• End-to-End Encryption: All communication is encrypted to protect data in transit.

• Audit Logs: Comprehensive logging tracks connection activity for compliance requirements.

• Password Policies: Enforce password requirements across your network.

• Data Sovereignty: Control where your data flows by deploying Hub in your preferred location or cloud region.

When to Use Hub

Add Hub to your solution when:

• You have hundreds or thousands of distributed sites

• You need secure connectivity, network architecture, or data routing at scale

• Data sovereignty or compliance requirements dictate control over where data flows

• You need a centralized aggregation point for OT data

• You require high availability with redundancy and failover

Customer Use Cases

Industrial Operations: A global energy company uses Hub for secure remote access across 700+ distributed sites. Combined with Tosi Control for centralized monitoring, they reduced site visit costs by 60% and improved response times by 75%.

Facilities Management: A commercial property network uses Hub to connect building systems across multiple locations, with Tosi Control providing automated alerts for downtime and centralized tracking of all locks and hubs.

Manufacturing: A manufacturing operation uses Hub to connect production facilities across three continents. Site managers receive instant notifications about connectivity issues before they impact production.

Proof Points

• 545 Hub installations deployed worldwide

• 70% reduction in required site visits

• 50% faster troubleshooting and response times

• 90% of issues resolved remotely

• 99.995% system uptime

• ROI typically achieved in under 12 months

Conclusion

Tosi Hub is the essential backend engine that powers secure, scalable OT connectivity. It handles the critical work of establishing encrypted connections, routing data, and maintaining persistent access across your distributed sites. As the Tosi Platform continues to evolve, Hub will remain the reliable infrastructure layer while Tosi Control serves as your unified command center for visibility, management, and monitoring. Together, they define the future of secure, connected OT networks.
