Network Visibility for Retail: Assess and Improve What You Can’t See

Skip to Key Ideas Q and A

Without visibility, there is no control. Distributed retail networks face a growing attack surface with interconnected systems like point-of-sale (POS) terminals, Internet of Things (IoT) sensors, guest Wi-Fi, and cloud apps. Network visibility provides real-time insights into device health, traffic flows, and potential threats—all essential to reducing dwell time, improving uptime, and simplifying compliance.

You can’t defend what you can’t see. As infrastructure grows more complex, blind spots multiply—especially across multiple store locations. A robust network visibility assessment ensures your team can:

• Detect lateral movement before attacks escalate
• Monitor critical systems like POS, inventory, and mobile devices
• Visualize performance bottlenecks and application latency

A framework for assessing network visibility

Retailers can improve visibility using a phased approach:

1. Discovery and topology mapping

Inventory all connected devices and map their logical and physical relationships—including POS systems, corporate Virtual Local Area Networks (VLANs), and third-party integrations. This baseline supports faster troubleshooting and segmentation planning.

2. Traffic flow analysis

Capture flow records (like NetFlow or sFlow) at store aggregation points to understand how traffic moves across segments. This helps identify anomalies like unauthorized east-west movement.

3. Endpoint and application monitoring

Pair endpoint telemetry with deep-packet inspection to tie user-level actions to network flows. This is essential for detecting misconfigured systems or compromised devices.

4. Logging and event correlation

Centralize log collection into a Security Information and Event Management (SIEM) platform. Correlate with threat intelligence feeds to surface meaningful alerts and satisfy compliance mandates like PCI DSS and SOX.

Key visibility metrics retailers should monitor

PDI VNOC: Visibility-as-a-Service

The PDI Virtual Network Operations Center (VNOC) provides 24/7 monitoring and alerting across all your retail locations via a centralized, cloud-based platform. Capabilities include:

• Persona-based dashboards for security, IT, and compliance teams
• Automated remediation when thresholds are breached
• Interactive network maps with live health and status
• Audit-ready compliance reporting for PCI DSS and SOX

Whether you operate 10 stores or 1,000 stores, VNOC scales with you.

Execution and continuous improvement

Visibility isn’t a one-time project—it’s an ongoing discipline:

• Baseline validation: Benchmark current visibility against industry norms
• Gap remediation: Deploy sensors or logging agents to cover blind spots
• Policy tuning: Calibrate alert thresholds and event correlation rules
• Quarterly reviews: Adjust monitoring scope as store layouts and tools evolve
