What is OT Secure Remote Access Software in Europe?
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.

Dispel
Dispel
The industry's fastest remote access system that exceeds cybersecurity standards. Remote access is useful only if your team chooses to use it. That means it must be more than a security spec sheet. It must be fast, intuitive, and yes, look good. A person on a company's warehouse tablet selects the system they need to reach. Device and protocol whitelisting are hidden from view. The intense escalation of demand under COVID broke the administrative processes underlying most remote access systems. Reestablish and maintain coherent control of your networks using Dispel, a platform built to condense information to the essentials and automate the task waterfalls that would otherwise bog down changepoint decisions. A vendor requests access through a form by defining their identity, reason for access, access scope, and time frame. The request is logged and automatically sent to an administrator, who can approve or deny the request. -
