3 Popular Open Source and Free Remote Desktop Software

These three free remote desktop software tools will help your IT team access and control remote devices to troubleshoot tech issues.

Ankita SinghContent Writer

Consider one of your employees is traveling for business or working remotely and faces an unexpected technical glitch with the work laptop. Should the employee let a third-party vendor try fixing the IT issue? The answer is certainly not. Work devices store confidential business data and shouldn’t be accessed by any third party.  

During such situations, you can rely on remote desktop software. It sets up a secure remote desktop connection that lets your IT team request access and control any employee’s system remotely to troubleshoot issues. IT teams can also use the software to install and update applications and transfer files between the connected systems. Likewise, the software can be used to offer remote tech support to your clients or customers. 

If you’re looking to purchase a remote access tool but don’t know where to start, check out these three popular open source and free remote desktop solutions—based on Google’s search engine queries. All three tools offer a stand-alone free module to get you started. If you need more features, you can choose to upgrade.
