Used across industries

Cyber security

Detect Advanced Persistent Threats (APT) and other breaches to your network at 2×1/10G, 8x10G, 2×10/25G, 4×10/25G, 2x40G or 2x100G – no activity goes unnoticed.

Across industries, cyber assaults are accumulating at alarming rates. Hackers are constantly refining their tactics and repeatedly circumventing static defenses.

To identify any suspicious activity on your network, you need full visibility at all times. Even a marginal fraction of information lost can potentially compromise the safety of your business. Who has been on your network, what have they done, and when exactly did they do it? A myriad of intelligent security solutions are available to help you answer these questions – but to deliver the needed insights, they need fully reliable data. And with network speeds advancing to 40G or 100G, the challenge of attaining reliable data is firmly growing.

With the Napatech NT200A02 SmartNIC, we help you ensure that no data is lost and no activity goes unnoticed. Napatech provides guaranteed delivery of network data, and supply all the information needed for effective forensic analysis in real-time, even at speeds up to 40G or 100G. This means a much shorter response time, improved mitigation and ultimately a reinforced security. 

Telecom operators

Break the cost/performance barrier.

With the increasing number of telecom carriers migrating to 25G, 40G, 50G and 100G solutions, the need to continually upgrade network performance is growing. But monitoring and analyzing 2x100G of communication brings certain challenges. The common approach requires a comprehensive system of numerous 10G lines connected to a range of appliances – but this escalates both complexity and cost.

The NT200A02 SmartNIC from Napatech enables direct analysis of 100G with just a single server. It merges upstream and downstream data so specific information can be delivered directly to the right CPU core even for fragmented traffic and GTP tunnels. This lowers the processing load on the CPUs and enables the application to efficiently analyze the target data in 1U form factor servers.

With the NT200A02 SmartNIC, applications will be able to monitor performance and analyze quality of experience even at 40G or 100G. This enables telecom operators to improve quality, while better managing the bandwidth challenges posed by rich media applications.

Cloud and data center

Enable full flow analysis of your infrastructure in real-time – and keep rackspace at a minimum.

Maintaining performance while enhancing services to accommodate 100G and beyond is fundamental to the long-term viability of cloud and data center businesses. Data center managers are further challenged to retain the lowest possible CAPEX and OPEX.

With the NT200A02 SmartNIC, Napatech is helping the industry to tackle these challenges. Because of its compact design, this solution enables 2x40G/2x100G applications in 1U server platforms, thus saving rack space and cutting costs while maintaining integrity and performance.

With the colossal growth of web-based applications and cloud services, users are demanding greater access to data at faster speeds. Network operators are in continuous pursuit of more effective monitoring and analysis solutions to help them boost performance. But even the best solutions cannot deliver without completely reliable data.

The NT200A02 SmartNIC guarantees quick and accurate data delivery even at 40G or 100G. Traffic on the two 40G or 100G ports is timestamped with nanosecond precision and delivered to the network application in the right order – a huge benefit for the analysis of network traffic. This enables network solutions to instantly and effectively identify and remediate any performance issues – and ultimately helps to optimize infrastructure, increase network uptime and reduce the number of man-hours required to identify any issues.
