Industrial Identity & Access

Machine and human identity, certificate lifecycle and least-privilege access for controls engineers and vendors.

Overview

Shared engineering accounts, passwords taped inside panel doors and certificates nobody tracks are still the norm on many plants. They make attribution impossible and offboarding meaningless.

We put real identity behind both people and machines, without making the control room unworkable during an upset.

What is included

  • Human identity and role design for control environments
  • Machine and device identity
  • Certificate issuance, rotation and revocation lifecycle
  • Least-privilege access model by role and zone
  • Break-glass access with logging and review
  • Vendor and contractor identity lifecycle
  • Joiner, mover and leaver process for OT
  • Access review and attestation cycle

How we run it

  1. 01

    Scope

    Inventory who and what has access today, and to which zones.

  2. 02

    Build

    Design roles, certificate lifecycle and break-glass procedures with the controls team.

  3. 03

    Launch

    Roll out by zone, with shared accounts retired last and deliberately.

  4. 04

    Measure

    Run the first access review and hand over the attestation cycle.

Questions

Before you enquire

What happens during an emergency?
Break-glass access exists precisely for that, with logging and after-the-fact review rather than a blocked operator.
Can this work with legacy PLCs?
Device-level identity often cannot. We compensate at the zone and conduit layer, which is the realistic answer for older equipment.
How are vendors handled?
Time-bound, scoped, logged access issued per engagement and revoked automatically at expiry.
