Contain the breach by design,
before it spreads.
Segmentation and micro-segmentation design built on real traffic, not guesswork. We map east-west flows and dependencies first, then enforce in phases, so lateral movement stops without stopping the business.
Flat networks turn one infection into an outage.
On a flat network, an attacker who compromises one laptop can reach servers, backups and domain controllers directly. That is how ransomware moves from a single click to an organization-wide outage. Segmentation puts boundaries in the way, so a compromise in one zone stays in that zone.
Most segmentation projects stall for the same reason: rules are written before anyone knows what actually talks to what, applications break, and enforcement is quietly switched off. We start with visibility. We map east-west traffic and application dependencies, design zones around how the business really works, and roll out policy in monitor mode before it enforces anything.
- An east-west traffic and application dependency map
- A trust-zone design: macro-segmentation across sites, data centres and cloud
- Micro-segmentation policy for high-value systems and workloads
- An IT/OT boundary design, where you run industrial systems
- A phased rollout plan with monitor-then-enforce stages and exception handling
- Lateral movement testing to prove the boundaries hold
See it, design it, enforce it, prove it.
Discover
We collect flow data and inventory assets to see what talks to what, including the dependencies nobody documented.
Design zones
We define trust boundaries around business function and data sensitivity: user networks, servers, crown-jewel systems, management planes, backups, OT.
Monitor mode
Policies are deployed to log rather than block. Application owners review what would have been stopped, and exceptions are agreed.
Enforce in phases
Zones move to enforcement one at a time, highest risk first, with a rollback for each change.
Validate
We test the boundaries the way an attacker would, then hand over policy management runbooks and a review cycle so rules do not decay.
Three outcomes of good segmentation.
Smaller blast radius
A compromise in one zone cannot reach backups, domain controllers or production systems directly.
Better visibility
East-west traffic that crosses a boundary can be logged and watched, giving detection a place to look.
Reduced compliance scope
Isolating card, health or regulated data can shrink the systems in scope for frameworks such as PCI DSS.
Who it is for
Organizations with large flat networks, several sites or data centres, a mix of cloud and on-prem, or industrial systems sharing a network with corporate IT. Also teams working on ransomware resilience or compliance scope reduction.
- Zero trust, segmentation as one pillar of a wider programme
- Ransomware readiness, test how far ransomware would get
- OT & ICS security, the IT/OT boundary in depth
- Penetration testing, prove the boundaries hold
What buyers ask.
We tried segmentation before and it broke things.
Usually because rules came before discovery. We map dependencies first and run every policy in monitor mode before enforcing it, so breakage shows up in a log, not in production.
Do we need to buy a micro-segmentation product?
Not necessarily. We are vendor-agnostic. Your existing firewalls, endpoint agents or cloud-native controls may be enough, and we recommend new tooling only where they are not.
How long does it take?
It depends on the size and complexity of the estate. Because enforcement is phased, the highest-risk zones are protected early, rather than waiting for the whole network.
How do we know it works?
We test it. Lateral movement testing tries to cross every boundary the way an attacker would, and the results go into the handover.
Stop one compromise from becoming all of them.
