Securing critical infrastructure with identity security

Delinea helps organizations secure privileged access across operational technology (OT) environments, from enterprise IT and cloud-connected services to the plant floor. With controls for credentials, remote sessions, endpoints, and identity visibility, teams can reduce risk without disrupting operations.

Reduce privilege risk without disrupting operations
Start with your highest-risk access paths and phase in controls safely, without forcing change windows OT teams cannot absorb.

Unified control across credentials, sessions, endpoints & identities
One modular platform to govern credentials, broker remote access, enforce least privilege, and gain visibility into privileged identities across OT.

Built for segmented, hybrid, and distributed OT environments
Supports air-gapped zones, legacy systems, remote vendors, and mixed on-prem and cloud environments without risky architectural change.

Delinea reduces Operational Technology privilege risk through practical, layered controls that can be deployed in phases without forcing disruptive change across operational networks.

Protect privileged credentials

Identify administrator, service, local, and root accounts across PLCs, HMIs, engineering workstations, OT servers, and supporting infrastructure. Secure them in a centralized vault and rotate passwords on approved schedules to reduce reliance on default credentials, shared accounts, and the access paths most likely to cause unplanned operational disruption.

Control remote sessions

Broker vendor and engineer remote sessions through secure access paths — without shared credentials, standing VPN access, or unmanaged connections. Every session can be proxied, monitored, and recorded, with a full audit trail showing who accessed what, when, and what changed.

Enforce least privilege and prevent unauthorized change

Remove unnecessary local administrator rights from engineering workstations and OT endpoints. Apply controlled elevation and application control so users can complete required tasks without standing admin access, reducing the blast radius of compromise and limiting unauthorized actions that could affect safety, availability, or system integrity.

Gain visibility into service and technical accounts

Many OT environments have accumulated service accounts, technical accounts, and privileged identities over years, often with limited visibility or ownership. Delinea helps teams discover and assess these identities across segmented OT, enterprise IT, and cloud-connected environments. This reduces blind spots, clarifying ownership and identifying risky access paths before they become operational problems.

Support segmented OT identity models

OT environments often maintain separate directories, isolated domains, or distinct identity patterns by design. Delinea supports consistent privilege governance across IT and OT environments without collapsing security zones or forcing a one-size-fits-all architecture.

Apply compensating controls when patching is constrained

When fragile OT systems cannot be patched on IT timelines, Delinea helps reduce exploitability through stronger authentication, tighter access control, and more disciplined privilege management — limiting who can reach critical systems and what they can do once connected.

Strengthen audit readiness and accountability

Capture session recordings, activity logs, and privileged access records across vendors, engineers, and administrators. Every access event is fully auditable, making compliance reviews more defensible and investigations faster.

Support compliance across OT and hybrid environments

Align privileged access controls to OT security and compliance requirements across on-prem and connected environments. Delinea supports the controls and audit evidence required by NERC CIP, IEC 62443, NIST SP 800-82, and CMMC.
