Network Security

Harden security and accelerate recovery at wire speed


is the key to our success

Networks are under constant threat.


Without monitoring the right tools to see the right traffic, your network security, speed, cost and efficiency are compromised.


Our products provide your security systems with complete, uncompromising visibility into your network. You will find that this helps to keep pace with increasing network speed and complexity, while gaining the insight needed to better detect and contain breaches, and achieve a rapid recovery. By implementing Network Critical solutions you can improve your existing security system's network performance, therefore increasing your ROI. 

“Unauthorized manipulation of our monitoring systems can have serious safety and production consequences. Network Critical TAP’s help us manage security without impacting network traffic.”

How Do Network TAPs Work? 
Part 1: TAPs vs SPAN Ports

Only used to using SPAN Ports to connect your network security and monitoring tools? Then you should be used to the numerous problems that come with them... introducing the Network TAP. The only answer to secure, always-on, total Network Visibility.

The Challenges Security Teams Face

Firstly, SPAN ports. These have been a long-term, insufficient, solution to network security. It is remarkably easy for hackers to infiltrate routers, switches and entire networks without detection. SPAN does not provide access to real-time information either, which is another key issue that may greatly affect your network's security. This is because SPAN ports groom your data, unlike Network TAPs, that act as a window, where you can look through at any time, in real-time. Finally, when you need to heavily utilise your SPAN port, the switch performance becomes compromised, affecting performance.

A secure network, therefore, starts with a strategic and thorough network security architecture, as well as implementing the next-generation ethernet TAPs and packet brokers to successfully and smoothly monitor your network's traffic. But what next?

After these high-investment and time-consuming efforts, you may find that you are still not receiving all of the traffic that you were hoping for. This is because malware may be masked within TLS or SSL traffic, varying percentages of missing packets and potential blind spots of traffic may never reach your security tools, and while you are trying to figure the reasoning behind this, criminals are building knowledge on how to outwit perimeter detection and enter your network in different ways.

We have engineered our network TAPs and packet brokers from the ground up, ensuring 100% traffic visibility which means we are able to ensure that all threats, no matter how small, are able to pass through our TAPs and ultimately your monitoring solution. Battling against the Network Team for access or control of network data will also be an issue of the past, as our ethernet TAPs allow for collaboration between NetOps and SecOps, which is key for a successfully run network.

The Solutions That Security Teams Need

If you are concerned that your SPAN port is not doing enough for your network's security, you should consider SmartNA Network TAPs for excellence in network monitoring and visibility. Our Network TAP range allows for complete, 100% visibility, into your network. So you can be alerted, in real-time, on any and all issues that your network may be facing.
