Specialized
OT & ICS Security Services in Pakistan
Specialized assessments for industrial control and OT environments.
What it is
Operational technology does not tolerate the testing IT networks shrug off. We assess industrial environments the way they must be assessed: passively first, with safety and availability as the binding constraint, focusing on the IT/OT boundary where nearly every real incident has begun.
Types of OT/ICS Security we deliver
OT asset discovery
Establishing what is actually on the plant network, usually passively. Most sites have devices nobody has a record of.
Network segmentation review
Whether IT and OT are genuinely separated. This is the control that matters most and the one most often assumed rather than verified.
SCADA and PLC security assessment
Control system configuration, authentication and exposure, assessed without interfering with the process.
Passive OT monitoring
Visibility into the control network using techniques that never inject traffic.
OT incident response planning
Response procedures written for an environment where you cannot simply isolate and rebuild a machine mid-process.
Remote access review
Vendor and engineer access into the plant, which is how OT environments are most often reached in practice.
How we do it
-
1
Passive asset discovery
Traffic is captured and analysed rather than probed, so controllers and sensors are never interrogated by a scanner.
-
2
Protocol analysis
Modbus, DNP3, S7, EtherNet/IP and OPC UA traffic reviewed for authentication, integrity and unexpected commands.
-
3
IT/OT boundary review
The conduit between corporate and industrial networks — jump hosts, historians, remote access and dual-homed machines.
-
4
Purdue model mapping
Where your architecture actually sits against the reference model, and which levels can talk to which.
-
5
Remote access review
Vendor connections and support tunnels, historically the most common route into an industrial network.
-
6
Safety-bounded validation
Any active testing is agreed in writing, scheduled around operations, and stopped the moment a process is affected.
What's included
- Passive-first methodology
- Industrial protocol traffic analysis
- IT/OT conduit and boundary assessment
- Purdue level mapping of the real architecture
- Vendor remote access review
- IEC 62443 aligned findings
Who needs it
- Manufacturing plants with connected production lines
- Utilities, water and energy operators
- Any operator where downtime is measured in lost production, not tickets
Deliverables
- Passive asset inventory of the OT estate
- Network architecture diagram as found, against Purdue
- Conduit and remote access risk register
- Remediation plan sequenced around maintenance windows
What OT/ICS Security costs
Priced per site, and almost always on site rather than remotely.
The figure depends on scope, so we quote one fixed price in writing before any work begins. These are the things that move it:
- How many physical sites — OT work happens where the plant is. Each site is a separate visit with its own safety induction and its own escort requirements.
- Whether live systems may be touched at all — On most plants the answer is no, so assessment is passive — traffic capture, configuration review, architecture analysis. That is a different method, not a cheaper one.
- How many protocols and vendors are present — Modbus, DNP3, Profinet and a vendor-specific protocol on one site means several things to understand rather than one.
- Whether the IT/OT boundary is in scope — This is usually where the real exposure sits, and testing it properly means working from both sides of the boundary.
- Shutdown windows — Anything that must wait for a maintenance window is scheduled around production, which affects the calendar more than the price.
Start with a passive assessment and the boundary review. It carries no production risk and it is where the first round of findings almost always comes from.
Where we deliver OT/ICS Security
OT work is on-site by nature, because you cannot assess a plant network from a laptop in another city. Our Multan base covers the industrial corridor of southern Punjab, including textile, sugar, cement, fertiliser and agri-processing operations, and we travel nationwide for energy, water and manufacturing sites.

Frequently asked questions
Yes — the passive phase requires no interaction with control devices at all. Active testing is optional, separately agreed, and normally scheduled into a planned outage.
The opposite. Legacy controllers cannot be patched, so the protection has to come from segmentation, conduit control and monitoring — which is exactly what this assessment evaluates.
Where you want us to. Vendor remote access is often the weakest link, and vendors frequently need to be part of the remediation conversation.
Only if it is done differently from IT testing, and that is the entire discipline. We work passively by default, never scan a live control network with IT tooling, and anything active happens only during a planned outage with your engineers present. A scanner that is harmless on an office network can halt a PLC.
The priorities invert. IT protects confidentiality first; OT protects availability and safety first, because the consequence of failure is physical. Equipment often runs for twenty years, cannot be patched, and cannot be rebooted on demand, so segmentation and compensating controls matter far more than patching.
Nearly every air-gapped network we assess turns out not to be. Vendor remote access, an engineering laptop that moves between both sides, a historian bridging to the corporate network, a USB used for updates, or an unrecorded wireless link. Verifying the gap is usually the single most valuable finding.
Manufacturing, textile, sugar, cement, fertiliser and agri-processing, plus energy, water and utilities. Southern Punjab has a concentration of exactly these, and the assessment is adapted to the process rather than applied as a template.
That is the normal situation and it is planned for. Passive monitoring, configuration review, documentation review and interviews can all be done with production running. Anything that could affect the process is reserved for a scheduled outage, and we tell you clearly which findings require one.
IEC 62443 as the primary framework for industrial control security, with NIST SP 800-82 for guidance. Where a site also sits under PISF critical infrastructure obligations, we map the findings onto those as well so you are not running two separate programmes.
Priced per site, and almost always on site rather than remotely. Beyond that the figure depends on scope — mainly how many physical sites, whether live systems may be touched at all and how many protocols and vendors are present. We quote one fixed price in writing before any work begins, so the number does not move once the engagement starts. Start with a passive assessment and the boundary review. It carries no production risk and it is where the first round of findings almost always comes from.
