In order to access all the traffic running across your network (Layer 1 - 7), you need to have access by "tapping" the network at critical points. The products from Network Critical enable network managers and administrators to unobtrusively connect and manage intelligent peripherals on networks.

 

Established in 1997 by Alastair Hartrup, Network Critical has grown to become the market leading designer and manufacturer of network access solutions for the security and network management marketplace, offering customers flexible deployment options to maximize their solution investment.

 

Our products are of the highest quality, designed by the best engineers in the business, and as a result Network Critical has a reputation for leading the industry with technological advances in the TAP (test access point) marketplace.  Worldwide “firsts” include the 100% guaranteed 'zero packet loss' TAP, the 4x4 port 1U rack mount Critical TAP, the multi-port Fiber TAP and the introduction of the Critical In-line TAP.  More recently, we've introduced the powerful CriticalConnex™ CC3100 TAP, which allows a gigabit network tool to passively monitor four 10/100 network links - even at maximum utilization of all links, it won't drop a single packet. A CriticalTAP™ solution provides non-intrusive network access points for critical security and monitoring solutions such as intrusion detection and prevention and network performance analysis. By implementing these solutions with a CriticalTAP™ end users can view traffic without interference or impairment to the network.

 

We specialize in providing high-performance network TAP solutions which are critical elements in building security and monitoring capabilities into communications networks. Our standard CriticalTAP™ products are ALWAYS in stock and available for immediate delivery. Custom solutions are available upon request and can take as little as 48 hours.

 

Safely Inline, Virtually Inline


 V-Line™ Bypass TAPs

 
 
 


Once deployed, the V-Line™ will continually check the health of the inline appliance with heartbeat packets injected into the traffic stream on one side of the appliance and checked and removed on the other side. The heartbeats follow a rigorous algorithm that is biased towards maximum network security by allowing traffic to flow through the inline appliance under high traffic and/or packet processing conditions.

If the inline appliance fails and is not passing traffic, then the V-Line™ hardware will detect the loss of the heartbeat and automatically bypass the inline appliance and allow traffic to flow along the network uninterrupted. The V-Line™ continues to send out the heartbeat testing connectivity of the inline appliance and if it recovers then the V-Line™ will immediately bring it back online.
 

  
 

Network Critical Security Solutions
 

In Line Deployment of Security Solutions

With many customers now deploying inline security devices there has proven to be a requirement for a complimentary product that offers additional protection for the many change control demands, as well as offering High Availability / Redundancy capabilities in this deployment scenario – Introducing the Network Critical V-Line™ TAP.
 

The V-Line™ provides complete failsafe protection for an inline appliance in one simple step; installed in place of the appliance the TAP continually checks the appliance network status and while it is online directs network traffic through it. If the appliance goes offline the TAP automatically bypasses it and traffic is directed straight through to the network devices. When the appliance comes online again traffic is immediately directed through it again.
 

This capability is vital for customers who want to deploy inline appliances on mission critical network segments but simply can’t afford the risk of unscheduled downtime or the costly dilemma of scheduled downtime for configuration changes, maintenance or repair scenarios.

In addition to the V-Line™ primary IPS Sensor ports, a secondary pair of inline appliance ports is provided. If the primary appliance fails and a secondary appliance is available, the V-Line™ will pass the network traffic through the secondary appliance therefore providing the High Availability / Redundancy that is not available on many inline appliances.

One of the key features of the V-Line™ is that when a customer is looking to deploy an inline appliance they only have to down the network once, thus greatly improving the ease of deployment and significantly reducing the associated costs. Without the V-Line™ the customer would have to first down the network for the initial deployment, down it again for maintenance or unforeseen issues and if this were the case, potentially down it a third time for re-deployment of the amended solution – The V-Line™ completely removes the need for this costly and disruptive process!
