TL;DR: Manufacturing cyberattacks can halt production, delay shipments, and force manual recovery, according to Securden’s guide on privileged access management in plant environments. The operational lesson is that standing access, shared credentials, and unmanaged vendor or machine identities turn cyber risk into uptime risk, so PAM becomes a production control, not just an audit control.
Editorial analysis by NHI Mgmt Group, based on content published by Securden: “Top 10 PAM Use Cases for Securing Manufacturing IT, OT, and Plant Operations”.
Key questions
Q: What breaks when vendors use shared privileged access in manufacturing environments?
A: Shared vendor access breaks accountability, because the organisation can no longer tie a command, configuration change, or data action to one person.
A: Unmanaged vendor access creates risk because industrial systems often have long lifecycles, multiple external maintainers, and limited visibility into who is connected at any moment.
Q: How should teams govern service accounts and automation secrets in plant operations?
A: Treat them as governed identities, not embedded configuration.
Practitioner guidance
- Segment privileged access by environment Separate IT, OT and vendor access paths so administrative rights for one zone do not automatically extend into production-critical systems.
- Enforce time-bound vendor approvals Require approved maintenance windows, hidden credentials and recorded sessions for all OEM, contractor and integrator access, with automatic expiry after the task ends.
- Remove standing local admin rights Replace permanent administrator rights on engineering workstations and operator endpoints with controlled elevation for named tasks and approved applications.
Bottom line: Manufacturing risk is not limited to data exposure when privileged access reaches IT and OT systems.

Manufacturing PAM is a production control before it is an access control. The article is right to frame uptime, shipment flow and manual recovery as the real business consequences of privileged access failure. In industrial environments, the security boundary is the process line, not the login screen, which means access governance has to be judged against operational continuity. Practitioners should treat privileged access policy as part of production resilience.
A few things that frame the scale:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: How can manufacturers reduce the blast radius of privilege on endpoints and OT systems?
A: By removing standing local admin rights, limiting elevation to approved tasks and separating plant access from general IT administration. That narrows the damage a compromised endpoint or misused account can do and makes privileged activity visible enough to investigate and audit.
