Core Components of a Network Infrastructure Review
A comprehensive review begins by documenting the current network architecture and identifying how infrastructure components interact. The assessment should cover both physical and virtual environments, including on-premises systems, cloud networks, hybrid connectivity, and third-party services.
- Network architecture: Review routers, switches, firewalls, gateways, wireless access points, network segments, and connectivity paths.
- Performance: Evaluate bandwidth, latency, availability, throughput, capacity utilization, and recurring performance patterns.
- Security: Examine access controls, segmentation, firewall policies, authentication, encryption, monitoring, and security governance.
- Resilience: Assess redundancy, backup connectivity, failover mechanisms, recovery procedures, and dependency on individual infrastructure components.
- Operations: Review monitoring, configuration management, documentation, change controls, asset inventories, and incident-management processes.
Network Infrastructure and ERP Environments
Network performance directly affects enterprise applications because ERP platforms depend on reliable connectivity between users, application servers, databases, integrations, and external services. A review should therefore map network dependencies before an ERP implementation, integration, or migration.
ERP Infrastructure provides a useful framework for understanding the technology foundation supporting ERP applications, while How Many Levels Does a Typical ERP System Include? can help teams understand how infrastructure relates to application, integration, data, and higher-level ERP capabilities.
For organizations modernizing legacy environments, Infrastructure Migration should be assessed alongside network dependencies so that connectivity requirements, application interfaces, data flows, and security controls remain aligned throughout the transition.
Security, Controls, and Auditability
Security is an important part of a Network Infrastructure Review because network architecture determines how users, applications, devices, and external systems communicate. The review should assess whether sensitive financial and operational systems are appropriately segmented and whether access is governed according to business requirements.
Auditability also matters when network activity supports financial processes. Audit Trails can provide records of actions performed within vendor-management workflows, including steps taken by humans or AI, helping organizations maintain transparency and support operational review.
Network controls should also align with accounting and reporting requirements. A well-maintained chart of accounts, for example, supports consistent financial classification, while network and application controls help protect the systems through which general-ledger transactions, reporting data, and financial records are processed.
Network Performance and Business Operations
Network infrastructure should be evaluated in terms of the business processes it supports rather than only its technical specifications. Finance applications, procurement systems, customer platforms, collaboration tools, and data analytics workloads may have different latency, availability, bandwidth, and security requirements.
Procure-to-pay workflows provide a practical example. A purchase order may pass through procurement applications, ERP systems, approval workflows, supplier portals, and financial systems. Reliable connectivity across these environments supports timely approvals, spend visibility, and accurate transaction processing.
The review should also identify capacity requirements for future workloads. Cloud adoption, remote access, analytics, AI services, additional integrations, and higher transaction volumes can change network utilization and should be reflected in infrastructure planning.
Infrastructure Optimization and Modernization
After documenting the current environment, organizations can identify opportunities to improve architecture, capacity, resilience, security, and operational efficiency. Infrastructure Optimization focuses on aligning infrastructure resources with actual business requirements while improving utilization, performance, and maintainability.
Modernization initiatives should be prioritized according to business impact. Critical finance and ERP connectivity may require stronger redundancy and monitoring than lower-priority workloads. Similarly, cloud and hybrid environments may require additional controls for identity, network segmentation, traffic routing, and integration security.

Review Process and Best Practices
A practical Network Infrastructure Review typically starts with an inventory of network assets and dependencies, followed by architecture analysis, performance assessment, security evaluation, and business-impact prioritization. Findings should be documented in a format that connects technical observations with operational and financial consequences.
- Build an accurate asset inventory: Record network devices, services, connections, configurations, ownership, and critical dependencies.
- Map business dependencies: Identify which financial, ERP, procurement, customer, and operational processes rely on each major network component.
- Measure actual performance: Use availability, latency, bandwidth, capacity, and incident data rather than relying solely on theoretical specifications.
- Review security controls: Validate segmentation, authentication, access permissions, firewall rules, encryption, and monitoring.
- Prioritize improvements: Rank recommendations according to business criticality, operational efficiency, resilience, security, and future scalability.
Summary
Network Infrastructure Review evaluates the architecture, performance, security, resilience, and operational controls supporting an organization's technology environment. By connecting infrastructure findings with ERP systems, finance applications, procurement workflows, accounting controls, and modernization plans, organizations can make better technology and financial decisions. Regular review also provides a foundation for Infrastructure Optimization, stronger resilience, and scalable business operations.
