Making Everyone The Expert
Become the Expert with Network Critical
There's no need to referee your network and security teams. Network Critical's Network TAPs and Packet Brokers, along with their secret sauce, the Drag-n-Vu™ management system, are here to help by making everyone the expert.
The Network TAP
Test Access Points (TAPs), often referred to as Ethernet TAPs or Network TAPs, are stand-alone hardware devices that create an identical copy of all of traffic flowing between two end-points in a network. With decades of research and development, Network Critical promote this tapping technology to all network managers because it fully configurable, enables complex packet manipulation and achieves total visibility into the network.
Being able to use a fully configurable network TAP is important for network managers to obtain holistic control and flexibility of their network. The copied traffic undergoes complex packet manipulation, as it is output to various network tools; such as security and performance tools. All this is completed while the live traffic continues to pass through the network, without disturbance. This zero-impact of the network is crucial for avoiding downtime which could cost companies thousands, to billions, of dollars.
Network Critical provide the highest quality network TAPs because it is crucial for achieving a secure base layer of Smart Network Access.
The Network Packet Broker
Network Critical's Network Packet Brokers have been developed to collect information by facilitating security and monitoring technologies, allowing for network managers to gain insight into exactly what traffic is required for optimized performance. The packet broker is also able to minimize threats, resource waste and costs because they can apply specific rules and filters before they forward the traffic to your various network tools, such as performance management and network security.
The 'Broker' in Network Packet Broker refers to its ability to combine, integrate, separate, manipulate and process inputs from many sources, delivering the data to a wide variety of appliance and tool destinations. Delivering the right data to the right tool will optimize security and performance. Network Critical's SmartNA Network Packet Broker range are hybrid, so in 1RU device, both Network TAP and Packet Broker technology is present which makes the SmartNA packet brokers highly effective in saving costs and rack space.
Zero packet loss with total traffic capture
Single pane-of-glass GUI, Drag-n-Vu™ rule optimisation engine calculates all filter rule interaction automatically.
Load-Balance traffic to multiple monitoring and analysis tools.
Intelligent aggregation of traffic from multiple Network TAPs or SPAN ports.
Intelligent traffic filtering, ensuring that security and monitoring tools see all the data they need.
Application layer visibility allows for efficient packet processing on individual L7 protocols.
The Bypass TAP
Network Critical's V-Line™ Bypass TAPs, have been designed to have consistent heartbeats that are sent to an Inline security appliance. These heartbeats indicate the functionality of the security appliance: regular beats means the Bypass TAP is functioning well. If the beats are not returned to the Bypass TAP the TAP automatically bypasses the appliance to allow the packets to be sent through, no matter how high the traffic is (see below). This is vital to users due to it's speed and ability to ensure no impact on the network. It is has a feature that detects the status of the appliance, so when it comes back online, this is detected by the TAP and traffic is once again directed through the appliance.
When an IPS or other Inline Appliance is installed behind the V-Line™ TAP, the TAP continually checks the status of the appliance and if it is online, will direct traffic through it. It also is very beneficial to the network team because if the appliance goes for maintenance or update, or any reason, the TAP will automatically bypass the appliance and direct traffic straight through to the network, ensuring zero downtime.
