3. NetLimiter

NetLimiter is a bandwidth throttling tool that enables the user to allow or block applications and control the amount of bandwidth they’re allowed to use. NetLimiter comes with three tools that let you control network traffic: Limits, Priorities, and Blocker. Limits enable you to set a maximum bandwidth transfer speed limit for an application.

The Priorities tool allows you to pick which application traffic has priority. NetLimiter has an internal priority engine, which automatically restricts other applications when a high priority application is in use. There are four priority levels that can be assigned: Critical, High, Normal, and Low.

Blocker allows you to block particular applications such as non-work services to minimize distractions. All of these tools can be customized with filters with the Filter Editor. Here you can filter applications by a full path, part of the path, localhost/loopback traffic, local IP address, destination IP address, local port numbers, remote port numbers, and more.

NetLimiter is ideal for enterprises that desire a simple traffic monitoring tool for Windows. NetLimiter is available for Windows 7, Vista, 8, 10, Server 2008 R2, Server 2012, and Server 2016. A Standard License costs $29.95 (£24). You can download the software from this link here.

  • Prioritize traffic
  • Customizable filters

4. NetBalancer

NetBalancer is a dynamic bandwidth limiter that lets you control traffic usage on your computer. With NetBalancer you can implement download and upload limits to determine how many network resources are limited to an application. Traffic rules and filters give you complete control over the applications being used on your network.

The software also provides you with transparency over traffic and processes. You can view a history of upload and download traffic history, which you can interact with to edit the color scheme and adjust the time frame. There are also pie charts that you can use to view traffic data such as the top processes IPs in the last 24 hours.

For managing multiple computers, NetBalancer has a web-based console where you can synchronize settings. Simply set a time frame for the sync to take place and then check the events, traffic, and command settings that will be synced. All data will be encrypted and protected by TLS and SHA2 for additional security.
