Learn What an Application Whitelist is and why it’s Necessary

An application whitelist is a list of appropriate applications that can be accessed by anyone on the server. The administrator can set parameters to approve various apps that must be used for work and can set who can use them and when. For example, some programs are required by the IT department but no one else at the firm. These programs can be whitelisted for the IT department only so that they can use them, but others can’t.

The purpose is to protect networks and computers from applications that are considered harmful. It can also be used as a way to prevent too much demand for resources when those resources aren’t necessary.

At Comodo, we understand the benefits of whitelists and want to make it understood to everyone why they are needed and what they are.


Now that you know what a whitelist is, it’s time to figure out what they’re used for and why. It is a simple list of all applications that are approved for use by users or administrators. They do not require further clicks or checks to be used. When any app on the computer or server tries to run, the list will be checked to ensure it has permission. If it does, it will run. If it doesn’t, many things could happen, including:

  • The user gets an error message of some kind
  • The app asks for permission, and if they aren’t logged in as an administrator, it fails
  • It is noted in the record as a failed attempt
  • Provide protection features
  • Anti-malware and antivirus protection
  • Help you whitelist easily

The whitelist can help ensure the safety and security of hardware and software and is recommended for organizations of all sorts. It can also make sure that approved applications can be used. Contact us today if you’d like to learn more.
