Network Security

Network security designed around zero-trust principles

Segment, harden and monitor networks across data centres, cloud and remote access using zero-trust principles.

The problem

Why this matters

Flat networks allow an attacker who compromises a single endpoint to move laterally to critical systems. Legacy VPNs and broad firewall rules accumulated over years make it difficult to reason about which connections are actually required.

Common challenges

  • Flat internal networks with broad east-west access
  • Firewall rule bases that nobody fully understands
  • Remote access that grants network-level rather than application-level access
  • Limited visibility into encrypted traffic and lateral movement

Our approach

How we work

  1. Baseline

    Map flows between systems and identify critical assets and trust zones.

  2. Segment

    Design micro-segmentation aligned to application dependencies.

  3. Replace implicit trust

    Move remote and third-party access to identity-aware, per-application access.

  4. Detect

    Instrument network telemetry for lateral movement and exfiltration detection.

FAQ

Frequently asked questions

Do we need to replace our firewalls to adopt zero trust?

Usually not. Zero trust is an architecture, not a product. Most organisations progress by tightening segmentation and access policy on existing infrastructure while modernising remote access.
