What is On-Premises OT Secure Remote Access Software?
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.

BeyondTrust Endpoint Privilege Management
BeyondTrust
Eliminate unnecessary privileges and elevate rights to Windows, Mac, Unix, Linux and network devices without hindering productivity. Our experience implementing across over 50 million endpoints has helped create a deployment approach with rapid time to value. Available on-premise or in the cloud, BeyondTrust enables you to eliminate admin rights quickly and efficiently, without disrupting user productivity or driving up service desk tickets. Unix and Linux systems present high-value targets for external attackers and malicious insiders. The same holds true for networked devices, such as IoT, ICS and SCADA. Gaining root or other privileged credentials makes it easy for attackers to fly under the radar and access sensitive systems and data. BeyondTrust Privilege Management for Unix & Linux is an enterprise-class, gold-standard privilege management solution that helps security and IT organizations achieve compliance.
