From Blind Trust to Full Visibility: How to Take Control of Third-Party OT Access
Can Cybersecurity Drive Growth? The Strategic Role of Secure Remote Access in Manufacturing
Secure Your Legacy OT Systems with Zero Downtime or Disruptions
Cyolo Unveils Major New Capabilities, Expanding Secure Remote Access Coverage for OT and Cyber-Physical Systems
One challenge. Two perspectives.
A single unified solution.
IT is tasked with securing every remote connection and preventing unauthorized access. OT is focused on keeping critical systems running smoothly and safely.
Cyolo PRO (Privileged Remote Operations) is the access solution that meets both sides' needs.
For IT Teams
Enforce least-privilege access, multi-factor authentication (MFA), and session recording across OT environments
Add modern security authentication to legacy OT systems without infrastructure changes
Achieve true Zero Trust by keeping all passwords and secrets inside your trusted boundaries
Extend Active Directory, Okta, Azure AD into OT environments without identity silos
Get privileged remote access controls without PAM overhead or complexity
No added IT workload — works with your existing tech stack and tools, no redesign or reconfiguration required
For OT Teams
No downtime during deployment or day-to-day operations
Nothing installed on critical or sensitive systems and no hardware required
Safe, secure access for both internal staff and third-party vendors
Works seamlessly across air-gapped, on-prem, cloud-based, and hybrid environments
Provides clear visibility to see who accessed what, when, and why
Accelerates support, maintenance, and issue resolution
Built-in compliance with NIS2, IEC 62443, NERC CIP, and other key industry regulations
Different Priorities. One Seamless Experience.
Cyolo reduces IT workloads while giving OT uninterrupted operations. With agentless, self-service access, IT teams spend less time resolving support tickets and more time driving strategic priorities.
No infrastructure changes. No agents. No risk to operations.
