Packet Sniffers are used in many different situations, networks, troubleshooting and investigative scenarios.
We've compiled a large list of the Best Packet Sniffer Software & Tools for you to use in your daily network administration tasks.
If you have been an IT Administrator for any length of time, you know that one of the most frustrating and time-consuming tasks is troubleshooting network problems.
In a company, big or small, network resiliency is of utmost importance especially in companies which rely on the internet and network connections for daily tasks.
That is why in events of network failure, it's the responsibility of an IT Administrator to troubleshoot and fix the problem as soon as possible – Each minute wasted is equal to money lost by the company.
Everyone involved in the IT industry knows for a fact that most of the time, traditional troubleshooting is either a hit or miss.
Sometimes, you might think that you have already fixed the problem but only caused a more significant network mishap because you mis-configured a server or network link.
To avoid these unfortunate events, Packet Sniffers were developed.
A Packet Sniffer is a piece of software or tool that analyzes and tracks inbound and outbound packets, monitors the network traffic and intercepts packets as well as records the path taken by the packet, and etc.
The information gathered from a Packet Sniffer will significantly help a Network Administrator troubleshoot and fix network errors in a smaller span of time by understanding what is going over the wire as well as source/destinations.
Packet Sniffers are used for some of the following tasks:
- Pinpointing High Bandwidth Users/Applications
- Troubleshooting Network Connectivity Issues
- Resolving DNS Issues
- Capacity Planning
- Malware Analysis and Prevent
- Active and Passive IDS and IPS
- and many more uses!
Listed below are some of Packet Sniffers, their features, pricing and other capabilities that they offer.

4. PRTG Network Monitor
PRTG is a professional network Monitoring software which has packet sniffing capabilities that provides a graphical overview of your network and allow you to monitor data packets. It filters according to IP addresses, protocols, and types of data.
It is Windows compatible and it uses different technologies including SNMP, Netflow, WMI, REST APIs for network traffic sniffing.
One of the main features that PRTG offers is the Dashboard which shows complete information about which applications uses the most bandwidth, and how much network traffic it causes in a quick and easy layout.
PRTG is often compared to other Network Monitoring solutions and its features outweigh many open source alternatives.
Another main feature offered by PRTG is the Packet Sniffer Sensor that tracks the packet and records the headers of each data packet. It can monitor:
- Total traffic
- Port sniffer
- Web traffic (HTTP, HTTPS)
- Mail traffic (IMAP, POP3, SMTP)
- File transfer traffic (FTP, P2P)
- Infrastructure traffic (DHCP, DNS, ICMP, SNMP)
- Remote control (RDP, SSH, VNC)
- Other UDP and TCP traffic
5. Steel Central Packet Analyzer
Steel Central Packet Analyzer offers an interactive graphical user interface that helps you identify the root network problem using a wide selection of pre-defined analysis views.
It provides packet sniffing down to the bit level through Packet Analyzer Plus’ full integration with Wireshark.
There are three versions of Steel Central Packet Analyzer that only differs in which products they support.
For personal networks, there is the Steel Central Packet Analyzer Personal Edition which offers the same level of packet sniffing but has a limited set of included features.
For small companies, Steel Central Packet Analyzer supports multiple products including NetShark Virtual Edition on SteelHead and SteelFusion.
Steel Central Packet Analyzer Plus is highly recommended for large companies with substantial network traffic since it can support the new Steel Central AppResponse 11.

Tcpdump is a command-line tool that was initially designed for UNIX systems and is often pre-installed on almost all Unix-like operating systems.
Tcpdump does not have an attractive user interface, but all packet information needed to determine the source of the network problem can be seen on display.
Since it is a command-line packet sniffing tool, you do not need to have a heavy duty PC to run it smoothly, as you can literally fire up the command line tool and start sniffing fairly quickly.
There is a bit of a learning curve though and its not nearly as intuitive as other programs in this list.
Tcpdump uses very basic to complex codes and commands so it would take time to master how to operate this tool fully.
But once you get the hang of it, it would be straightforward for an IT administrator to get around and identify the causes of network issues. It has been ported to Windows as Windump.
NetworkMiner for Windows makes network analysis very simple and can detect the host-name as well as the OS and open ports of network hosts through packet sniffing.
It can also operate offline by parsing a PCAP file for further analysis and reassemble sent certificates from PCAP files.
NetworkMiner was released in 2007 by Netresec and since its release, it has been a widely-used tool by companies and organizations all over the world.
In this day and age where wireless networks are in high demand, Kismet can work wonders in packet sniffing since it was developed specifically for wireless networks.
It can detect and sniff packet even from hidden networks and SSIDs.
It can detect the presence of wireless APs as well as clients and what kind of traffic they create – this is especially useful for creating WiFi Heat Maps and such.
Kismet also has a counterpart that is compatible with MAC and OSX environments, KisMAC. They both have simple and easy to learn user interfaces.
Fiddler is not technically made for packet sniffing but can be used either way. It can manipulate and log HTTP/HTTPS traffic.
May it be on a desktop or on non-web applications, as long as it uses HTTP/HTTPS for connections, Fiddler can analyze the traffic and help you determine which causes the heaviest network traffic.
Since it is an open source tool, administrators use Fiddler to isolate performance bottlenecks. It also offers web debugging and HTTPS traffic decryption.
Fundamentally, EtherApe and WireShark offer the same features, but they differ in the representation of data.
This open-source packet sniffer is more focused on giving a visual interpretation of the information on the packets. The data displayed can be changed to show only the data you need.
Some features offered by EtherApe include but are not limited to:
• Protocol summary dialog shows global traffic statistics by protocol.
• Node summary dialog shows traffic statistics by node.
• Node statistics export to XML file.
• A single node can be centered on the display and several user-chosen nodes can be arranged in an inner circle with other nodes around.
• An alternative display mode arranges nodes in “columns”.
11. Packet Capture
As society moves to mobile devices, integration and sniffing of the Android platform is a definite must.
Packet Capture app can record and capture network packets using a local VPN. SSL communication can be decrypted using the Man In The Middle (MITM) approach.
