By aggregating, enriching, and exporting flow information from diverse devices across campus, data center, and cloud environments, the Flow Collector 4200 helps security operations centers (SOCs) and network teams collaborate more effectively, reducing blind spots and enabling precise enforcement of security policies. The appliance is built to handle demanding enterprise networks, delivering reliable throughput, robust data processing, and intuitive management that accelerates deployment and day-to-day operations. With Cisco’s proven security lineage and a design focused on operational efficiency, the Flow Collector 4200 empowers organizations to convert network telemetry into measurable security outcomes and improved network reliability.

• Unmatched visibility and scalable flow collection: Designed to capture high-fidelity NetFlow, IPFIX and sFlow data across campus and data center networks, the Flow Collector 4200 provides comprehensive visibility into who talks to whom, when, and how. Its scalable architecture supports growing traffic volumes and complex topologies, ensuring that security analytics keep pace with evolving networks. By aggregating flow data from multiple devices and aggregators, it creates a unified view of network activity, enabling proactive threat hunting, rapid anomaly detection, and precise capacity planning. This results in faster detection of unusual patterns, application performance issues, and potential security incidents before they impact business operations.
• Advanced analytics for actionable insights: Beyond simple flow capture, the Flow Collector 4200 preprocesses, enriches, and exports data to Stealthwatch for in-depth analysis. The device enables real-time analytics on traffic patterns, user behavior, and application usage, turning raw telemetry into meaningful security decisions. With near real-time visibility into west-to-east west traffic, east-to-west communications, and inter-VLAN activity, security teams gain the context needed to distinguish normal from anomalous activity, prioritize investigations, and accelerate incident response. The result is improved threat detection accuracy, reduced time to containment, and a clearer understanding of how applications traverse the network and affect performance.
• Seamless integration with Cisco Stealthwatch ecosystem: The Flow Collector 4200 is engineered to work in concert with the broader Stealthwatch solution, feeding rich flow data into centralized dashboards and policy frameworks. By harmonizing data across multiple collectors and sensors, it supports unified security policies, consistent alerting, and consolidated reporting. This integration enables SOC teams to correlate flow-derived insights with additional telemetry, threat intel, and user context, delivering a more complete security picture and simplifying operations across distributed environments.
• Reliability, security, and operational efficiency: Built to meet enterprise-grade reliability, the Flow Collector 4200 incorporates redundant components and robust security features to ensure continuity of visibility. Features such as secure export of flow data, role-based access control, and hardened management interfaces help protect sensitive telemetry from unauthorized access. Intuitive management and streamlined deployment reduce the burden on IT staff, while automation-friendly workflows enable faster onboarding of new devices and scalable expansion as network demands grow. This combination of reliability and efficiency translates into lower total cost of ownership and a stronger security posture.
• Easy deployment and flexible integration: The Flow Collector 4200 is designed for straightforward installation in data centers or network operation centers, with rack-mount form factor and familiar Cisco management interfaces. It supports rapid integration with existing boundary devices and traffic taps, allowing organizations to extend visibility without interrupting production networks. Whether you are consolidating telemetry from on-premises infrastructure or extending your monitoring to virtualized and cloud environments, the Flow Collector 4200 provides a consistent, scalable path to enhanced network security and performance analytics.

How to install Cisco Stealthwatch Flow Collector 4200

Step 1: Plan and prepare — Assess your network topology and determine the optimal placement for flow collection, considering data-center clustering, campus segments, and cloud connectivity. Identify the management network and the data network paths that will carry flow information to the Flow Collector 4200. Prepare the necessary rack space, power, and network cables, and ensure you have the required credentials for initial configuration and Stealthwatch integration.

Step 2: rack, cable, and power — Install the Flow Collector 4200 in a standard 19-inch rack, align with other network equipment, and connect redundant power supplies if available. Ensure proper cable management to minimize interference and airflow restrictions. Verify that the device boots correctly and reaches the management network for initial configuration.

Step 3: connect to management and data networks — Attach the Flow Collector 4200 to the management network for administration and to the data network(s) where flow data originates or interfaces with network devices. Ensure that appropriate firewall rules and access controls permit communication with the Stealthwatch Console and other telemetry sources.

Step 4: initial configuration and onboarding — Access the management interface and perform the initial setup, including date/time settings, network parameters, and security roles. Register the Flow Collector 4200 with the Cisco Stealthwatch Console, enabling it to receive and process flow data. Configure data export parameters (protocols, sampling rates, and destination dashboards or analytics nodes) in accordance with your security policy.

Step 5: enable flow capture and enrichment — Activate NetFlow/IPFIX (and sFlow where supported) on boundary devices or taps, and verify that flow records are being exported to the Flow Collector 4200. Confirm that collected data is enriched with metadata such as application identifiers, user context, and device information as supported by your Stealthwatch deployment.

Step 6: validate and tune — Use the Stealthwatch dashboard to validate data ingestion, verify data accuracy, and adjust sampling, timing, or filtering parameters to balance visibility with resource utilization. Establish baseline metrics and alert thresholds for rapid detection of anomalies, ensuring your SOC can respond effectively to security events.

Step 7: hardened operations and redundancy — Configure role-based access controls, monitor for hardware health, and enable redundancy options if your deployment requires high availability. Document the deployment topology, maintenance windows, and escalation paths to streamline ongoing operations and future expansions.
