NIS2 OT Quick Scan & GAP Analysis
NIS2 is in working order. The question isn’t if OT environments will be evaluated, but when.
The NIS2 OT Quick Scan & GAP Analysis gives you a clear overview of OT assets, network traffic and most urgent gaps in a matter of weeks. All without impact on production.
Why now?
OT environments are different from IT. Continuity, safety and availability are no nice-to-haves but the core of production and processing environments.
A classic IT audit doesn’t keep that in mind as much as it should. The NIS2 OT Quick Scan is built on the reality of OT. The approach is passive and non-intrusive: processes keep working while we map out what happens in the OT network, which assets are present and where the most important risks are.
The result is no abstract checklist, but a list of clearly defined priorities with which OT, IT, security and management teams can start working immediately.
For whom?
This Quick Scan is intended for organizations with OT environments who:
- Fall under NIS2 regulations or want to prepare themselves for an audit
- Need clear points of improvement, not a theoretical report
- Want more insights into assets, network traffic and risks
- Want a detailed, comprehensive roadmap to improve OT security maturity
Typical environments are production facilities, process industries and infrastructural organizations where continuity and safety regarding critical processes are non-negotiable.
What does the Quick Scan entail?
OT Asset Discovery
Agidens visualizes relevant OT assets: SCADA systems, PLC’s, engineering stations, servers, network components and critical communication flows.
This creates a clear view of what is available, how systems communicate and which assets are important for the continuity of processes.
Passieve network monitoring baseline
No active scanning, no disruptions and no impact on installations.
Through passive observation of the OT network traffic, for example through SPAN-port, TAP or existing tools, Agidens analyses communication patterns, dependabilities and possible risks.
Readiness Check
Agidens evaluates the current OT environment maturity in relation to the relevant NIS2 principles and the CCB CyberFundamentals.
The main focus isn’t really compliance, but rather what is applicable and relevant in the specific OT context.
Quick Risk Assessment
Agidens evaluates the major OT risks based on a limited set of core areas: network segmentation, remote access, back-up, patching, monitoring, logging and administrative processes.
Roadmaps
You’ll receive a clear management report with an overview of risks, maturity, priorities and actionable points. Furthermore, OT, IT and security teams will receive a technical attachment with observations, insights into assets and flows and concrete gaps.
Agidens translates the findings into a practical remediation roadmap with quick wins, must-haves, budget input and priorities to improve OT security maturity.
Our approach in 5 steps
Intake & scope
Together we determine which OT zone, production cell or site will be inspected and which stakeholders and objectives are leading.
Documentation review
Agidens reviews available architectural documentation, policies, procedures and existing security measures. This creates full context during technical observations and allows for findings to be interpreted correctly.
Passive baseline
During 2 to 4 weeks, Agidens observes the OT network traffic (depending on the scope), the number of network segments and the preferred monitoring depth.
GAP- and risk analysis
Agidens analyzes the findings in relation to NIS2, CyberFundamentals and OT security best practices. The evaluation happens based on OT relevance, impact on continuity and priorities for improvement.
Roadmap workshop
During a joint session with OT, IT, security and management, we discuss priorities, quick wins and next steps. The result is an actionable plan.
What is the result?
Afterwards you will have:
- A clear view of OT assets, critical communication flows and possible weak spots
- Insights into priority NIS2 and CyberFundamentals gaps in the specific OT context
- Clear improvements and investment priorities, ranked on impact
- A roadmap with quick wins, structural improvements and budget input
- A base for further, optional, support through OT Care
Possible follow up trajectories
OT observation for 3 to 6 months to keep an eye out for trends, deviations and asset enrichment
Remediation support on segmentation, firewall rules, remote access, back-up and patching
Managed OT Care with periodic health checks, monitoring and reporting

Ready to receive insights?
An OT environment needs an approach that fits the reality of the installations. The Quick Scan delivers that quickly, safely and without disruption of production.
Why Agidens
Agidens knows production and processing environments from the inside. We understand that cybersecurity measures in OT always have to keep in mind continuity, safety and operational feasability.
This translates into recommendations that are realistic: no generic checklist that teams cannot execute, but practical steps that fit installations, people and risks.
The results of the Quick Scan can flow directly into Agidens OT Care Essential or OT Care Premium. This way the analysis is not a singular snapshot, but it becomes the basis for continuous improvement and monitoring.
