narrowin — Network Assessment. A clear, actionable picture of your network.

[ Why it matters ]

Put budget and effort where the risk actually is.

Network spending and maintenance windows usually go on instinct: the loudest complaint, the last outage, whatever a vendor is selling. An assessment replaces instinct with a ranked, evidence-based picture: what to fix now, what to plan, and what can safely wait, so the money and the hours land where they genuinely cut risk.

01

Outdated documentation

The network changed over the years; the diagrams didn't. You can't prioritise what you can't see.

02

Slow troubleshooting

Dependencies and recent changes are hard to reconstruct under pressure, so effort goes to the symptom, not the cause.

03

A segmentation project ahead

The team knows architecture work is coming, but without a clear starting point the budget is a guess.

04

Rising audit pressure

NIS2 and the IKT-Minimalstandard raise the bar, and you need to know where the real gaps are before you spend.

[ What we assess ]

Four angles on the network: structure, configuration, security, operations.

We focus on the technical and operational issues that decide security, resilience and maintainability, working from real network data, not interviews and spreadsheets alone.

A · ARCHITECTURE & TOPOLOGY

How the network is built

Topology and segmentation review
Layer 2 and Layer 3 structure
Redundancy and resilience
Single points of failure

B · CONFIGURATION QUALITY

How consistently it is run

Configuration drift
Weak defaults and inconsistency
Monitoring and management setup
Backup and change quality

C · SECURITY EXPOSURE

Where it can be reached

Access and encryption review
Zone and VLAN weaknesses
Administrative exposure
Practical risk hotspots

D · OPERATIONS & MAINTENANCE

How well it can be kept

Recovery readiness
Documentation quality
Change-management maturity
Automation opportunities

[ How it works ]

From unclear to a concrete next decision.

The assessment creates usable clarity quickly, then turns that clarity into the next practical step.

1

Kickoff

We define scope, questions, constraints and the parts of the network that matter most.

2

Data collection

Explorer-based discovery maps devices, topology and recent change context, read-only.

3

Analysis

We review structure, resilience, operational quality and security posture from several angles.

4

Workshop

We walk the findings through together, explain the tradeoffs and focus the next decisions.

5

Next step

You leave with a prioritised set of decisions: what to fix now, what to plan, and what can safely wait.

[ What you get ]

Output meant to be used, not archived.

01

Current-state overview

A usable picture of the network and its main dependencies: the map you can actually trust.

02

Prioritised findings

A focused summary of the structural and operational risks that matter most, ranked, not listed.

03

Practical next steps

Recommendations that support real architecture, operations and investment decisions.

Through the visibility gained, we could immediately identify measures to improve network security and stability. The Explorer helps us segment the OT network, find errors faster during outages, and continuously track network expansion. This saves us a lot of time.

[ Frequently asked ]

The specifics.

How long does an assessment take?

Typically 4–6 weeks, depending on scope and your team's availability. Speed is the point: it creates usable clarity quickly, without becoming a major project.

Is this suitable for OT environments?

Yes. It is specifically built for OT and mixed IT/OT environments, where visibility is uneven and invasive methods aren't acceptable. Discovery is read-only: no agents, no SPAN ports.
