Network Security
Assume the perimeter is gone. Build for it.
Network Security is segmentation, inspection, and containment for networks where users, workloads, and attackers are all already inside. We design for the breach that has probably happened, so that one compromised laptop or one exposed service does not become the whole estate.
What it does
The network used to have an inside and an outside, and security lived at the line between them. That line no longer exists in any useful sense. Staff work from anywhere, workloads span data centres and three clouds, suppliers hold VPN credentials, and the operational technology on the factory floor talks to the internet whether anyone intended it to or not. An attacker who gets one foothold — a phished credential, an unpatched appliance — finds a flat network and walks.
We redesign for that reality. The estate is segmented so a compromise is contained to the segment it landed in. Access is granted per user, per device, per application, and verified continuously rather than once at a gateway. Traffic is inspected where it matters and detections are tuned to what is normal for your network, not a vendor's default. When something does get in, the containment playbook is already written and rehearsed.
Capabilities
Architecture review and micro-segmentation
The estate is mapped as it actually is — including the paths nobody documented — and redesigned into segments with explicit, least-privilege policies between them. Lateral movement stops at the boundary.
Zero-trust network access
Users and devices reach specific applications after identity, device health, and context are verified — not a network range after a VPN handshake. Access is re-evaluated continuously.
Traffic inspection and threat detection
Inspection at the points that matter, decrypted where policy allows, with detections tuned against your traffic so command-and-control, exfiltration, and scanning surface without drowning the team in false positives.
DDoS resilience and edge protection
Volumetric and application-layer attack absorption at the edge, rate limiting and bot management for public services, and tested failover so an attack degrades gracefully instead of taking you offline.
Secure remote access and site connectivity
Modern encrypted tunnels for staff, sites, and cloud connectivity, replacing legacy VPN concentrators and unmanaged site-to-site links with something you can see, patch, and revoke.
Containment playbooks
Pre-written, rehearsed procedures for isolating a host, a segment, or a site — with the network changes scripted so containment takes minutes and does not depend on who is on shift.
Frameworks we work against
Designs are grounded in the architectures and threat models the industry has already agreed on, so they hold up to your auditors and your red team alike.
- NIST SP 800-207
- The zero-trust architecture reference that access design, policy enforcement points, and continuous verification are built on.
- IEC 62443
- Zone and conduit segmentation for operational technology, so plant networks are protected without breaking the processes they run.
- MITRE ATT&CK
- Detections and playbooks are mapped to adversary techniques, so coverage can be measured against how attackers actually move.
- TLS 1.3
- Modern transport encryption enforced across internal and external services, with legacy protocol versions retired.
- IPsec / WireGuard
- Encrypted site-to-site and remote-access tunnels using current, auditable protocols rather than proprietary appliances.
- NIST CSF
- The Cybersecurity Framework functions used to structure the programme and report maturity to leadership.
Why teams bring us in
— Lateral movement stops at the segment
A compromised endpoint reaches the handful of systems it is meant to reach and nothing else. The incident stays an incident instead of becoming a breach.
— Detection tuned to your traffic, not a default ruleset
Alerts are calibrated against what normal looks like on your network. The team investigates real signals instead of clearing a queue of noise every morning.
— Contain first, investigate second
Because isolation is scripted and rehearsed, the first response to a suspected compromise is to cut it off — in minutes — and then work out what happened with the attacker already locked out.

Show us your network diagram. Then let us draw the real one.
We will map the estate as it actually connects, mark where a single compromise would spread, and hand you a segmentation plan with the first three changes ready to make.
