[FIXED] What is Cisco Leap Module and Should you remove it?

As a regular user of windows, there might be a time when you are going through installed programs in your computer and you might come across one of these programs – Cisco EAP-FAST Module, Cisco LEAP Module, and Cisco PEAP Module. Another name is isuspm.exe for the leap module program. You might wonder what are these programs? Are these safe for your PC or laptop and should you uninstall it or uninstalling it will create any problem? Don’t worry, we at livefortech will give you all of your answers today.


What are the Cisco module programs?

Cisco leap module programs are a bundle of programs by Cisco which include :

  • EAP-FAST = Extensible Authentication Protocol-Flexible Authentication via Secure Tunneling
  • PEAP = Protected Extensible Authentication Protocol
  • LEAP = Lightweight Extensible Authentication Protocol

These programs are offered as a package with cisco Softwares which are developed by Cisco, a well-known networking company.

Cisco Leap Module or isuspm.exe

Cisco LEAP module is an 802.1X authentication type for wireless LANs (WLANs) that supports strong authentication between the client and RADIUS server using a login password as the shared secret one. It provides dynamic per user, per session encryption keys too. This program can be installed on Windows XP/Vista/7/8/10 environment running PC or laptop.

Cisco LEAP module takes advantage of the standard 802.1X framework. Cisco was the pioneer in introducing Extensible Authentication Protocol (EAP) support for WLANs at a time when none of the existing client operating systems provided EAP support. Cisco Systems introduced Cisco LEAP in December 2000 as a way to quickly improve the overall security of WLAN authentication.

Should you remove Cisco leap module, Cisco EAP-FAST Module, or Cisco PEAP Module?

You need to ask yourself these questions :

  1. Have you ever connected to a domain network?
  2. Have you used CISCO products earlier?
  3. Were there any recent changes made on the computer prior to the issue?

If you haven’t used domain network ever and you are not using any Cisco products, you can go ahead and delete/uninstall cisco LEAP, Cisco EAP-fast, and Cisco PEAP and it won’t cause any problem.

If you accidentally removed Cisco modules from your computer, then it won’t cause any problem because Cisco LEAP/PEAP is a WiFi extension protocol, rarely used these days, and only in some larger company/education wireless systems. If you do really need it (which is unlikely), re-installing the WiFi software for your computer should do that.

That’s it for the post. We hope you got complete information about what is Cisco leap (isuspm.exe), EAP-fast, and PEAP modules and how they work and should you remove it from your pc. We hope you found this post informative. Share this post with your friends so that they can know about this too. Leave a comment if you have any doubts.

  1. Would help if you spell out what you mean by a “domain network”. I am one (of many) who have a local WiFi setup at home, and wonder if that fits the meaning.
    (I also want to be able to connect when at a store or motel, but that is much less common.) Windows 7 starts and runs Slowly on the old laptop, and this seems a candidate for removal.

    1. Your like me. A network of one. I get so irritated with HP, Google, Microsoft. They want me to store things in the cloud and share my printer with I don’t know who. I just want to play my games and sit here by myself, A Network of One

  2. This is why I hate personal computers. This shlt drives me crazy. I have to waste time researching these things when they suddenly appear on my computer BY THEMSELVES. Now I have to determine if it’s malicious or not. Computers do not save you time or increase the quality of your life. Just the opposite – you become the slave of the computer. Millions of man hours saved . . . but billions of man hours lost.

  3. Thanks for your help with this. I discovered so much more useless(to me) software when I used Ccleaner Uninstall programs utility. None of these showed up in the Windows uninstall utility. For example, about six programs relating to Xbox, that I don’t use, and the Cisco modules mentioned. So I cleaned out a whole heap of unnecessary stuff. Cheers!
