If you or your business are looking for a remote control software for more corporate matters, rather than private, there are free remote PC software trials. TeamViewer, for example, offers a two-week trial, which allows users to explore a host of different features.
It is advisable to opt for a well-known and trusted solution like TeamViewer – not only for obvious security reasons, but also because it has a significant user base, providing the platform with continual feedback on bugs, errors, and security breaches.
It is even more important to check whether there is a broad user community and if the developers are still active and regularly provide updated versions.
For open source users, solid IT skills are definitely advisory, so you can tailor the program to your own requirements and ensure the level of security is up to par.
