Our Network Architecture Review Methodology
A design-level approach to assess how your network architecture protects critical assets.
Scope & Objectives
Agree networks, sites, business priorities and review objectives.
Documentation Review
Review network diagrams, data flows, standards and asset inventories.
Stakeholder Workshops
Validate design intent and operations with network and security teams.
Zone & Boundary Analysis
Assess segmentation design, trust boundaries and critical asset placement.
Control Placement Review
Evaluate firewalls, IDS/IPS, proxies and access controls in the design.
Resilience & Management Review
Assess redundancy, single points of failure and admin access paths.
Reporting
Deliver design findings, risk ratings and target-state recommendations.
Roadmap & Follow-Up
Agree a phased improvement roadmap and review progress.
Deliverables You Can Expect
Every engagement assesses design intent and implementation evidence, not diagrams alone.
Supporting Services
Extend architecture review into segmentation testing, configuration review and penetration testing.
Benefits of Network Security Architecture Review
An architecture review fixes design weaknesses that configuration and testing alone cannot.
Clear Trust Boundaries
Zones and data flows documented and understood.
Better Control Placement
Missing or misplaced controls identified.
Stronger Resilience
Single points of failure made visible.
Compliance & Audit Readiness
Documented design evidence for PCI DSS, ISO 27001 and RBI reviews.

Frequently Asked Questions
A design-level assessment of how your network is structured and protected, covering zones, trust boundaries, perimeter, remote access, control placement and resilience.
An architecture review assesses the design. Segmentation testing proves whether isolation works in practice, and a firewall rule set review analyzes the rules that enforce it.
Network diagrams, data flows, device inventories and access to network and security teams for workshops. Configuration samples may be reviewed to confirm the design.
No active testing is performed by default. Segmentation or penetration testing can be added to validate findings.
