SMB owners know exactly how costly a slow internet connection can be. It’s undoubtedly frustrating when you can’t send that critical email, can’t load your web console to see your online orders, can’t track your inventory position, or do any important network-related activity. Unfortunately, fixing this connection problem isn’t easy either and can take a lot of your time and effort. But, using a network analysis tool can take some weight off your shoulders. 

Network analysis tools will proactively monitor your networks and identify the gaps you can fix before they impact your business. In this article, I’ll explore what network analysis tools are, their benefits, and the top features they must include. I’ll also give you a rundown of the top 5 network analysis tools. First, let’s start with a brief understanding of network analysis. 

What Is Network Analysis?

As the name suggests, network analysis includes all the measures you take to analyze your network and the traffic passing through it. It helps you identify a faulty hardware device, spot malware, recognize a DDoS attack, understand bandwidth issues, etc. Here are some additional benefits of these tools.

Benefits of Network Analysis Tools

Network analysis tools can benefit your business in many ways:

  • Identifies security gaps to reduce the chances of cyberattacks
  • Spots potential attacks so that you can remediate them immediately
  • Saves time and effort in troubleshooting
  • Takes a proactive approach to avoid losses due to system downtime
  • Generates reports for auditing, capacity planning, and compliance

Now, going back to our example of a slow connection, a network analysis tool will determine the source of the problem. It’ll show if the problem is with your router, internet service provider (ISP), bandwidth, etc. You can then troubleshoot and fix the issue accordingly.

Before I move on to the must-have features of any network analysis tool, I’ll discuss the different types of network monitoring tools. Network monitoring is inextricably linked to network analysis, so you need to know the different types before you pick a solution.

4 Types of Network Monitors 

Network monitors analyze the network data to provide the contextual information you need to understand the status and issues in your network. Many network analysis tools combine two or more network monitors. Make sure you know which ones you need for your business. The different types of network monitors are as follows:

1. Performance Monitors 

Performance monitors use the Simple Network Management Protocol (SNMP) to query the network and get the critical information you need for troubleshooting. You can use this type to detect network faults and the health and performance of all compatible devices. With this information, you can narrow down the issue to a device or a specific part of the network, like faulty hardware. In essence, performance monitoring is a proactive approach that detects and diagnoses issues like slow internet connections.

2. Network Testing Tools

Network testing tools continuously scan and evaluate specific aspects of your network, like performance, bandwidth usage, etc. Ping and traceroute are popular network testing tools that help identify problems like failed connections and latency issues. These network testing tools also provide insights into whether your data packets reach the destination servers and the time it takes. 

You can determine the reason for your slow internet connection using this information. It can be bandwidth issues, a firewall blocking your packets, packet loss, etc. Understanding the root cause will then speed up the troubleshooting process. Accordingly, you can address the problem. 

3. Packet Sniffers

Packet sniffers analyze the data packets flowing through your network to ensure that they’re not malicious. It also helps to diagnose problems and point the source to a device, network, or application. When you use packet sniffers, you can determine if your slow connection is due to an impending attack by cybercriminals like a Denial of Service attack. That way, you can take countermeasures right away. 

4. Network Analyzers 

Network analyzers capture the data packets traveling through your network. In essence, they capture the source, destination, port numbers, network protocols, and other pertinent information. Armed with these details, you can decode network activity, analyze it for patterns, and even get a better idea of your network usage statistics. For example, network analyzers can resolve any network communication problems and help plan the network capacity in case of slow connections.

Your network analysis tool will use network monitors to help you pinpoint the issues in your network. But what other must-have features should your network analyzer have? I’ll cover that next.

Top 5 Must-Have Features of Network Analyzers

Before shopping for a network analysis tool that works best for you, start with a list of what you want. Below are some must-have features.

1. Communication with Switches 

The network analysis tool you choose must communicate easily and seamlessly with all kinds of switches. These switches include NetFlow, sFlow, AppFlow, IPFIX, and more. This ability to communicate with multiple switches adds versatility to your network, so you can include many types of devices. It can also come in handy if you have a remote workforce connecting to your network. 

2. Capturing Packet Streams

Choose a network analysis tool that captures packet streams and analyzes their contents to identify patterns in your traffic. For example, these packet streams can show that one or more apps are clogging the bandwidth, slowing down the entire network. To solve this, you can plan your bandwidth usage. You can also set policies to avoid the use of bandwidth-clogging streaming and peer-to-peer sharing apps.

3. Network Path and Protocol Analysis

Network analysis and protocol analysis are two must-have features in your tool. Your network analysis tool must analyze network paths to provide insights about network bottlenecks. For example, your slow internet speed can be due to an imminent DDoS attack. Meanwhile, protocol analysis deconstructs the data packets and analyzes them for potential issues like malware. You can then get bandwidth and network usage insights to identify the root problem and prepare better to remediate it.

4. Traffic Shaping Measures

Traffic shaping measures manage the traffic passing through your network. Essentially, they prioritize access to critical applications like VoIP. Your network analysis tool must identify the existing traffic shaping measures. That way, you can make room for some mission-critical communication. 

5. Free Trial and Value for Money

Your first priority when looking for a network analysis tool should be a free trial to get a hands-on feel of the tool. Based on your experience, you can determine its effectiveness for your common problems. Your tool must also be good value for money. A rule of thumb is to approximate the value of the potential returns from using the software and compare it with the cost. The returns must be hands down better. 

Based on the above criteria, I’ve narrowed your options to the 5 best network analysis tools for your company.
