Micro Segmentation Consulting
We split the network into zones ransomware cannot cross. Design, rollout and verification — on the infrastructure you already run.
What this solves
Ransomware needs nothing more than that. One infected device and a quarter of an hour is enough to spread across the whole environment. Backups reachable from the same network get encrypted along with everything else.
Microsegmentation takes that freedom away: even a successful intrusion stays inside one zone.
What the service covers
Then we design zones around real application dependencies, define east-west traffic policy, and roll it out in stages: monitoring first, enforcement second. We verify that the segmentation actually stops the traffic it is meant to stop, rather than assuming it from the configuration.
We work with what you already have wherever that is viable. We are vendor-independent and make no money selling licences.
How the work runs
-
Traffic mapping
We collect data on real network communication over a period representative of your business. Documentation is often stale; traffic is not.
-
Zone design
We draw boundaries around real application dependencies and agree them with the teams who run those applications.
-
Rollout in monitoring mode
Policies run without blocking at first. We see what would have been stopped and correct the design before anything breaks.
-
Enforcement and verification
We enable blocking in stages and test that traffic which should be stopped genuinely does not get through.
Outcomes
You also get something most organisations lack: a current map of network dependencies. It pays off at every subsequent infrastructure change, migration and compliance audit — including demonstrating the technical measures NIS2 asks for.
Frequently asked questions
Does microsegmentation require replacing network hardware?
Usually not. We start from what can be achieved with your current infrastructure — often the mechanisms are already licensed and simply unused. We recommend replacement only where the cost of keeping the current state exceeds the cost of changing it.
Will segmentation slow the network down or break working applications?
That is precisely why the first stage runs in monitoring mode: policies are active but block nothing. We see exactly what would have been stopped and fix the design before enforcement is switched on.
How long does it take?
It depends on the size of the environment and the number of applications. Traffic mapping alone needs a representative period — usually a few weeks — otherwise we miss infrequent processes such as a monthly finance close.
How is this different from plain VLANs?
VLANs divide the network into large areas, usually by location or department, and traffic inside such an area stays unrestricted. Microsegmentation goes down to individual systems and the dependencies between them, so an attack has no freedom even within a single VLAN.
Does it help with NIS2 compliance?
Yes. NIS2 requires you to demonstrate technical measures that limit the impact of an incident, and segmentation is among the most measurable. The dependency map produced along the way is useful as documentation in its own right.
