Microsegmentation
Flow discovery, policy modelling and phased enforcement without breaking production.
Network Security
Zero trust, implemented rather than announced
Flat networks turn a foothold into a crisis. We segment by blast radius, adopt SASE and ZTNA, rationalise NGFW policy and instrument the paths attackers actually use.
SASE & secure edge
SSE, ZTNA and SD-WAN convergence replacing legacy VPN and backhaul designs.
OT & industrial
IEC 62443 zone-and-conduit design for plants, grids and safety-critical systems.
Detection engineering
NDR deployment, telemetry pipelines and ATT&CK-mapped content for the SOC.
Scope
Engagement deliverables
- Current-state flow mapping across data centre, cloud and branch
- Segmentation strategy with enforcement roadmap and rollback design
- ZTNA rollout replacing remote access VPN for workforce and vendors
- Firewall and proxy estate rationalisation with policy hygiene automation
- DDoS and edge resilience architecture for internet-facing services
- IT/OT boundary design with unidirectional patterns where required
- Network telemetry strategy: flow logs, DNS, TLS metadata and packet capture
- Purple-team validation that segmentation holds under real lateral movement
Field note
Segmentation only counts once it has been attacked
Every ASNC segmentation programme ends with adversary emulation across the new boundaries. We publish which paths were blocked, which were not, and how long detection took — then fix what the exercise exposed.
Shrink the blast radius
Start with a flow discovery sprint and a segmentation model your network team can enforce.
