2. TCPdump
If you are looking for a simple and easy-to-use packet catcher, TCPdump might just be the perfect pick. It is basically a command-line packet capture tool facilitating packet capture and analysis. TCPdump is a lightweight tool using which you can access real-time network traffic directly from the command line. It doesn’t include any graphical interface.
TCPdump uses the Berkeley Packet Filter (BPF) syntax to filter the network packets and provide you with detailed insights. Unlike the other, it requires minimal system resources to run. Although the network analyzer works efficiently, you might need to integrate it with other supplemental tools to achieve a robust performance. Overall, TCPdump is popular among developers, especially for its simplicity and portability.

3. Paessler PRTG Network Monitor
Paessler is a robust network monitoring tool that comes with a dedicated packet sniffer. It is a collection of a variety of monitoring sensors. The PRTG packet sniffer efficiently filters out the packets and captures only their header. It offers you the freedom to decide whether to store these packet headers or simply calculate the metrics.
Paessler PRTG Network Monitor supports multiple alert options including email/ SMS alerts and other integrations. Besides, this packet sniffer can be used to monitor and analyze the performance of a wide range of sensors like IRC, WWW, RDP, TalNet, etc. Moreover, there is a customizable dashboard that you can easily set up just through drag-and-drop. The best thing about Paessler is its scalability. Although it comes with a bundle of sensors, you only have to pay for what you use. Hence, you are in the power of which tools to activate from the bundle.

4. SolarWinds
SolarWinds is another wholesome network performance monitor mostly known for its device status checks. Among the many features, it also has a packet capture tool. The SolarWinds packet analyzer operates more like a protocol analyzer that basically gathers the packet data but doesn’t store it. So, if you need a packet capture tool only for calculating the metrics, SolarWinds will get the job done.
This network monitoring tool is mostly preferred for its user-friendly interface and wide range of tools. It comes with a Quality of Experience Dashboard that displays the real-time network packets through visualization for better understanding and user experience. Moreover, it also includes versatile alerting mediums, robust data analysis, and much more.

5. Kismet
Next, we have Kismet, another network analyzer that best fits for wireless network detection. This packet capture tool fuels when it comes to detecting, analyzing, and sniffing network traffic. It is equipped with extensive network detection capabilities that make it the best choice for detecting hidden networks. In addition to in-depth analysis, it also utilizes features like rogue device detection to provide administrative security.
Kismet supports a wide range of wireless protocols and offers real-time intrusion detection. Besides, it has great integrations with other monitoring tools. Thus, you can export its data to the supported tool for further network analysis as well. With so many features, the learning curve of Kismet certainly becomes steeper. Hence, you might have to spend some time to get completely familiar with the application.

6. ManageEngine Netflow Analyzer
ManageEngine Netflow Analyzer is another powerful network analyzer that comes with a wide range of monitoring tools. It features an intuitive user interface along with a highly interactive dashboard to boost your productivity. The software is popularly known for its cross-platform compatibility and extensive protocol support. It includes IPFIX, NetStream, JFlow, NetFlow, sFlow, and AppFlow to perform in-depth analysis.
Fortunately, you also get access to the NeFlow generator, a packet capture tool. This network analyzer captures the packets in a network, scans the headers, performs extensive network traffic analysis, and generates NetFlow statistical data. However, rather than storing these packets, NeFlow eliminates them after calculating the metrics. ManageEngine is specifically built to operate in larger organizational environments that come with enterprise-ready tools and functionalities.

7. Ettercap
Ettercap is another robust tool dedicated to vulnerability testing. It is focused on man-in-the-middle-attacks scenarios thereby performing network protocol analysis and security auditing. This network analyzer comes with unique tools and integrations that make it stand out among the other generic options. For instance, it supports active and passive protocol dissection and ARP-based host discovery. These features help in live connection manipulation and discovering hosts in an active network.
Furthermore, Ettercap supports good integrations with other network monitoring tools. It facilitates you to export its data seamlessly to tools like Wireshark or SolarWinds for further inspection. Apart from that, Ettercap is highly compatible across multiple operating systems making it the go-to choice for vulnerability testing and network security checks.

8. Network Miner
Last but not least, Network Miner is yet another popular tool that specializes in passive network forensics. Network Miner captures data packets, analyzes network traffic, and represents the data in an easily accessible way. It captures and dissects the packets without even directly engaging with the network. As a result, Network Miner maintains minimal disruption while providing detailed data for each packet.
Additionally, it becomes an optimal choice for professionals, especially for its added features and integrations. It facilitates file extraction from network traffic and a passive approach towards network operations. You can efficiently use it parallel to other networking tools to achieve the most evident analysis. The only downfall is that Network Monitor is now preferable for real-time intrusion detection and offers limited customization options.
