7 Best Network Segmentation Software [2023 Recommended]

Read, review, and compare the best Network Segmentation Software to select the right one as per your requirement:

Network segmentation is quickly emerging as the hottest trend when it comes to methods we can adopt today to keep our data, OS, and cloud environments secure. Network Segmentation is basically a process by which a large network is divided into relatively smaller segments with each section kept isolated from the other.

Such segmentation allows network architects to set clearly defined protocols that dictate how traffic should move within an organization’s IT ecosystem.

Furthermore, it also dictates which devices can communicate with other devices on the network. Network segmentation is ideal for facilitating multi-dimensional firewall security that is drawn based on zero-trust policies.

Frequently Asked Questions

Q #1) What is segmentation in the network?

Answer: Segmentation in the network or network segmentation is a security strategy by which larger networks are divided into many smaller sections. All of these smaller segments are then kept isolated from each other.

This is largely done to ensure hackers and cyber-security threats do not have the means to move across the organization’s network environment. Network segmentation is largely done to protect a company’s data and cloud environment from security threats.

Q #2) What are the two methods of network segmentation?

Answer: There are two methods commonly used to undertake network segmentation. They are as follows:

  • Physical Segmentation: This type of segmentation involves the use of special hardware to divide network data. This method of segmentation is highly insecure and also challenging to manage. Plus, it only covers the perimeter.
  • Virtual Segmentation: Virtual Segmentation can secure your entire network, this includes the perimeter as well. The security policies deployed via virtual segmentation are far more fine-grained and specific. Carrying out virtual segmentation is also easy, thanks to special software.

Q #3) What are some of the best network segmentation practices?

Answer: Normally, security architects advocate for the following network segmentation best practices:

  • Avoid over-segmenting
  • Put a limit to third-party access
  • Monitor and audit the network regularly
  • Visualize network
  • Bring similar network resources together

Q #4) What are the goals of network segmentation?

Answer: With network segmentation, security architects have simple goals to accomplish. The goal is to prevent harmful traffic from making its way to vulnerable devices on the network. With network segmentation, the endpoints that contain vulnerable devices are isolated. This limits the risk of exposure they previously had.

Q #5) How effective is network segmentation?

Answer: Network segmentation is quite effective in protecting vulnerable devices on the network. This is why it is so popular nowadays. However, the degree of effectiveness that network segmentation delivers will largely depend on the security policies being deployed and the software being used.

Fortunately, you’ll be fine as long as you are opting for any of the 7 network segmentation tools recommended below.

Q #6) How do I segment my network?

Answer: You can effectively segment your network on the following parameters:

  • You can segment the network on the basis of users by determining who needs more and least privilege on your network.
  • You can separate guest Wi-Fi from Corporate Wi-Fi.
  • A segment to assign a dedicated section for IT staff to do their non-administrative tasks.
  • Create different sections for different department servers.
  • You can also opt to keep communication systems in their own network zones to boost their performance.
  • Lastly, you can segment networks based on customer databases.

Q #7) What device is used for network segmentation?

Answer: Different zones or parts of a computer network can be segmented using the following devices:

  • Routers
  • Switches
  • Bridges

Q #8) What is the best way to segment data?

Answer: You can adhere to the following tips to segment data in the best possible manner:

  • Initiate personalization and segmentation of data in real-time.
  • Identify and deploy the right segmentation strategy.
  • Prioritize data segments based on their value.
  • Take an omnichannel approach to segmentation.
