The 6 Best Bandwidth Monitoring Tools
Network bandwidth can be defined as the maximum capacity of data that can be transmitted over an internet connection at any given amount of time, usually measured in bits per second (bps). Think of your network connection as a road. The wider the road is, the more vehicles can travel on it. Similarly, the higher your network bandwidth is, the higher the number of devices you can connect and the more data that can travel across it.
However, your network bandwidth is not safe from issues of latency, bottlenecks, and congestion. A slow internet connection can often be the result of network bandwidth issues, and these can cost your business both time and money. To keep your network running smoothly and efficiently, detect suspicious network activity, and stay ahead of network outages, you need to actively monitor your bandwidth.
Luckily, there are plenty of tools that allow you to monitor and optimize your network bandwidth in real time. Here, we'll be discussing some of the top bandwidth monitoring tools you should consider.

We would recommend using free network bandwidth monitoring tools for users who want to monitor small networks or a single computer. For mid-sized to large businesses and enterprises, should instead invest in a paid bandwidth monitoring tool.
What is Network Bandwidth Monitoring?
Bandwidth refers to the maximum amount of data that can be transmitted over an internet connection at any given time. The higher the bandwidth your data connection has, the more data it is capable of sending or receiving.
Through this overview, we now realize that bandwidth is limited. For all networks, there is a limit to the amount of data they can send or receive at any given time. You want to make sure you don't cross this capacity since there is a limit to this capacity. Your network slows down considerably if you cross the bandwidth capacity. For businesses that need to stay online 24/7, a lagging network means a lot of time and money.
Bandwidth monitoring helps make sure this doesn't happen. Bandwidth monitoring, as the name suggests, allows you to oversee how bandwidth is utilized by devices in your network at any given time. By monitoring your network bandwidth, you can stay one step ahead of potential issues before they slow you down. You can track devices that are hogging up too much bandwidth or get alerts when bandwidth usage has crossed its limits. You can take preventative measures to optimize this usage.
How to Use Network Bandwidth Monitoring?
You can use network bandwidth monitoring in several ways. Most network performance monitors will be able to oversee how much bandwidth is being utilized at any given time and determine where bottlenecks are occurring. If you notice any bottlenecks, you can then take action. Here, we've discussed some of the basic ways you can use network bandwidth monitoring tools.
- Some network performance monitors allow you to perform network traffic analysis to uncover malware that may be taking over the available bandwidth. The network performance monitor scans for malware and eliminates it as required.
- A network bandwidth monitor allows you to keep track of QoS, in this case, the lowest possible amount of available bandwidth that the devices on the network can use. For businesses, your devices that demand more bandwidth will be allocated accordingly, so they can operate smoothly.
- As a user, you can limit the types of files and websites that can take up bandwidth on your network. For instance, large files that are hogging up resources may be restricted entirely.
- Another useful tool bandwidth monitors offer is the ability to track down devices that use the most bandwidth on your network, even when it is not needed.
What are the Benefits of Network Bandwidth Monitoring Tools?
Network bandwidth monitoring tools have a number of benefits listed below:
- They allow you to have a comprehensive view of how your bandwidth is allocated among connected devices. Businesses can see which applications are taking over bandwidth unnecessarily and which applications should be given more bandwidth to run smoothly.
- Network bandwidth monitoring offers you all the resources needed to perform this optimization. Where resources are already limited, you need to make sure bandwidth allocation is efficient.
That's not all network bandwidth monitoring tools do.
They also allow you to uncover malware or unusual network activity that may be taking over network bandwidth. If too many devices are hogging up bandwidth, your internet speed will drop considerably. And since more organizations now rely on the internet for their business-critical operations, this needs to be taken care of. It's important to understand how much bandwidth you need to run your day-to-day operations smoothly. Network bandwidth monitoring tools allow you to do exactly that.
What are the Risks of Network Bandwidth Monitoring Tools?
Network bandwidth monitoring tools are not always easy to operate, they have their challenges and risks. As a network admin, you can expect to have your fair share of these challenges.
For instance, finding the root cause of bandwidth issues. Not all bandwidth monitoring tools allow for deep packet-level analysis to get to the core of the issue. Sometimes troubleshooting alone can be too time-consuming. For others, knowing your bandwidth utilization and determining the correct allocations across departments, branch offices, and sites can be difficult if your software provides inadequate insight. Finally, not all bandwidth monitoring tools offer network behavior anomaly detection or protection against zero-day attacks. Effective threat detection remains a challenge for bandwidth monitoring tools.
What is the Importance of Network Bandwidth Monitoring Tools?
Here's why it's so important to use a network bandwidth monitoring tool:
- Determine your bandwidth requirements: Determining your network bandwidth requirements is now considered an essential part of any business management plan. IT admins often oversee how departments and offices should utilize bandwidth for optimized usage. The bandwidth you end up with also correlates to your networking costs. But budgeting too little bandwidth could lead to slower productivity, laggy networking, and lost clients. You can use network bandwidth monitoring tools to determine how many workstations are connected to your business, how many applications are running on your devices, and how much bandwidth each one is allocated. You can then optimize this allocation to fit your business needs. Critical applications are therefore given higher bandwidth allocation.
- Improve network performance: If your network is running consistently slowly, and you can't seem to pinpoint the root cause. Your bandwidth is likely running low. Network bandwidth monitoring tools allow you to analyze bandwidth usage and discover which factors are causing insufficient bandwidth consumption. You can then take action to improve network performance. This is particularly important if your business is scaling upwards. You should have sufficient bandwidth available to support the onset of new users on your network.
- Spend less money: A network bandwidth monitor will allow you to figure out how much bandwidth capacity your business needs. You may not know this, but some ISPs enforce a limit on the bandwidth your company can use. Exceeding this limit means getting billed with additional charges. Network bandwidth monitoring tools won't just help prevent your company from crossing this limit; they will also uncover any excess bandwidth you aren't using but are still paying for.
- Improve security: Finally, bandwidth monitoring tools are excellent at uncovering malicious network activity. Any malware that is present on your network will be taking up bandwidth and such tools will reveal this consumption. They can scan for malware and take preventative measures to ensure they are dealt with before they wreak havoc on your network.
