Here are 20 of the best free tools for monitoring devices, services, ports or protocols and analyzing traffic on your network. This list is intended to supplement 101 Free SysAdmin Tools. Even if you may have heard of some of these tools before, I’m confident that you’ll find a gem or two amongst this list.
1. GFI LanGuard (our award-winning paid solution)
People say it’s good to be modest and not to brag, but we’re so proud of our network management tool that we had to start the list with GFI LanGuard. You can use it to scan both small and large networks, in search of software vulnerabilities and unpatched or unlicensed applications. Information coming from up to 60,000 devices, running on Windows, Mac OS or Linux, will be shown in a centralized web console, so you’ll be able to see the state of your whole network at any moment and from any location.
With centralized patch management and network auditing, GFI LanGuard prevents potential compliance issues, but if you’re a sysadmin the fact that all machines are patched and secured will surely seem like a more important advantage. But, don’t take our word for it, download the free 30-day trial and try it out.
2. Microsoft Message Analyzer
Microsoft Message Analyzer, the successor to Microsoft Network Monitor 3.4, has an intuitive and flexible UI with effective filtering options that allow you to break down and drill into captured packets (or ‘messages’ as they are called in Message Analyzer). By adding ‘Color Rules’ to different protocol traffic, you can make scanning through areas of interest easier and faster.
Some of its highlighted features include automated data capture (using PowerShell cmdlets to start or stop traces based on a particular trigger), TLS/SSL decryption support and customizable filter expressions.
Microsoft Message Analyzer allows you to assess multiple log data sources from a single pane of glass. You can capture, view and analyze network protocol traffic side-by-side with other system or application events (e.g., Event Logs or SQL Tables), making it a valuable addition to your network toolkit.
When you launch Microsoft Message Analyzer, click ‘Start Local Trace’ to immediately start capturing traffic from the local machine, or ‘New Session’ to add a Data Source to capture.
3. Nagios

Net Tools 5 Mac
NetworkMiner captures network packets and then parses the data to extract files and images, helping you to reconstruct events that a user has taken on the network – it can also do this by parsing a pre-captured PCAP file. You can enter keywords which will be highlighted as network packets are being captured. NetworkMiner is classed as a Network Forensic Analysis Tool (NFAT) that can obtain information such as hostname, operating system and open ports from hosts.
In the example above, I set NetworkMiner to capture packets, opened a web browser and searched for “soccer” as a keyword on Google Images. The images displayed in the Images tab are what I saw during my browser session.
When you load NetworkMiner, choose a network adapter to bind to and hit the “Start” button to initiate the packet capture process.
