An Introduction to Drag-n-Vu™

Network Critical’s revolutionary Drag-n-Vu is a sophisticated computational engine with an intelligent and intuitive graphical user interface that enables fast, error-free configuration and simplifies change management.

GUI deployment

Significantly reduce your operational costs

Manually configuring what goes in and what comes out of your security and monitoring tools is a painfully slow, error-prone task. Mistakes in filter hierarchies or port assignments can create security vulnerabilities and service interruptions. The simplicity of Drag-n-Vu™ not only speeds up deployment, but reduces operational cost by allowing filter and mapping tasks to be performed by network administrators rather than engineering personnel. In network management, where change is the only constant, moving tool management downstream not only saves money but also decreases down-time during maintenance windows.


Use Cases and Features

  • Simple and accurate traffic configuration to direct and control traffic
    to performance and monitoring tools.


  • Create filters and flow-based data mapping with drag-and-drop simplicity,
    ensuring rapid detection and response to emerging threats.


  • Reduce operational costs and eliminate downtime during maintenance
    windows without the need for specialist engineering personnel.

A Drag-n-Vu™ use example: aggregation and filtering

Common use example: Aggregation & Filtering End-user has a number of SPAN ports and some ethernet TAPs in their architecture and want to leverage an IDS (Intrusion Detection System) to monitor their network for malicious activity or policy violations. In the below example we are showing 3 different ways to capture data traffic:


  • Module 1: This module shows 2 copper TAPs where A&C are transmit (Tx) and B&D are receive (Rx). Copies of the data traffic are pulled via the backplane, filtered for IPv4 traffic and then routed to module 4 port A

  • Module 2: This module shows 4 SPAN ports coming from network devices and aggregated in the backplane, filtered for IPv4 traffic and then routed to module 4 port A

  • Module 3: This module shows 4 ports connected from network TAPs and aggregated in the backplane, filtered for IPv4 traffic and then routed to module 4 port A

  • Module 4: This module shows all the filtered traffic from modules 1, 2 & 3 are being aggregated and sent to an IDS tool connected to port A.

This solution shows our hybrid TAP/packet broker aggregating all the traffic from different sources, applying a filter and then sending resulting data traffic to an IDS tool. NOTE: depending on the expected traffic volume, many end-users would enable load balancing and send multiple links to their IDS tools so no oversubscription could impact performance.
