What is OT Secure Remote Access Software in China?

OT secure remote access software enables authorized engineers, technicians, and third-party vendors to securely connect to Operational Technology (OT) networks — like industrial control systems (ICS), SCADA, PLCs, and other critical infrastructure — from remote locations. It replaces traditional VPNs and jump-servers with modern security practices such as Zero Trust Network Access (ZTNA), least-privilege access, multi-factor authentication (MFA), and session isolation to reduce attack surfaces. These solutions often include network segmentation, protocol isolation, access logging, and session recording to ensure compliance, auditability, and protection against credential theft or lateral movement. For legacy or vulnerable OT devices that cannot be patched easily, “network-cloaking” or “invisible network” techniques help hide devices from unauthorized scans. Overall, OT secure remote access software allows remote management, maintenance, and troubleshooting of critical infrastructure while preserving security, reliability, and compliance.

    Tosi

    The Tosi Platform is a purpose-built Cyber-Physical Systems platform designed specifically to secure, connect, and control Operational Technology (OT) networks and critical infrastructure. Unlike traditional IT tools adapted for OT, Tosi was engineered from the ground up for industrial environments: it supports native industrial protocols, tolerates extreme temperatures, and requires no complicated configuration. Deployment is rapid, sites can be up and running in under five minutes with a “plug-and-go” setup, allowing organizations to connect distributed infrastructure quickly and securely without specialized IT expertise. It implements a zero-trust security model with enterprise-grade protections: end-to-end 256-bit AES encryption, hardware-based authentication (with RSA keys), no open inbound ports, and ISO/IEC 27001:2022 certification. With Tosi, you get unified, centralized management through a single interface (TosiControl), enabling visual network topology views.
