OT / ICS Security

Security for industrial control systems that respects safety and uptime first.

What is OT / ICS security?

OT / ICS security protects the operational technology that runs physical processes, such as SCADA systems, PLCs and industrial networks, without putting safety or uptime at risk.

Industrial environments need a different approach from office IT. A scan that is routine on a laptop can stop a controller. A patch that is urgent on a server may have to wait for a planned shutdown.

We work between IT security teams and OT operators, delivering assessments and programs that respect safety, uptime and the constraints of industrial systems. The work starts by understanding the process, so security improvements strengthen resilience without putting operations at risk.

Who needs it?

  • Oil and gas, energy and utility operators
  • Manufacturers with connected production lines
  • Organizations whose IT and OT networks have grown together
  • Operators facing NERC CIP or IEC 62443 requirements

What problems does it address?

  • Industrial networks that can be reached from the office network
  • No reliable inventory of the devices on the plant floor
  • IT security tools and practices that could disrupt production if applied as-is
  • No incident response plan written for an industrial environment

What we do

  • IEC 62443 framework implementation
  • SCADA, DCS and PLC security assessments
  • Network segmentation based on the Purdue Model
  • Asset discovery and inventory
  • Vulnerability management for OT
  • Incident response planning for industrial environments
  • NERC CIP compliance support

Industries

Direct experience in oil and gas and manufacturing. The same approach applies to energy, utilities, water and other critical infrastructure, where the constraints of safety and uptime are much the same.

What happens afterward?

Recommendations are sequenced around your maintenance windows and safety requirements. Avertix can help plan and validate the changes with your operations and engineering teams.

How the engagement works

  1. Free consultation

    A 45-minute call with a senior consultant about your situation. It is a conversation, not an assessment. You leave with a recommended next step.

  2. Scope and rules

    Scope, constraints and price are agreed in writing before any work starts.

  3. The work

    Carried out by the senior consultant who scoped it.

  4. Report and walkthrough

    Findings ranked by business risk, with a walkthrough for the people who will act on them.

Questions about OT / ICS Security

Will the assessment disrupt operations?
The work starts by understanding the process, and it is planned to avoid disrupting it. Security improvements are meant to strengthen resilience without putting operations at risk.
Is the first consultation free?
Yes. The first call is a free 45-minute working session with a senior consultant. It is a conversation about your situation, not an assessment. You leave with a recommended next step and an idea of the cost, whether or not you hire us.
Is the work fixed scope?
Scope, constraints and price are agreed in writing before any work starts.
Who does the work?
The senior consultant who scopes the engagement is the person who does the work. It is not handed to a junior team.
