What is OT Secure Remote Access Software for Active Directory?

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.
