Virtual Network Computing (VNC) is an open source remote support utility that employs the RFB protocol. There are several notable products based on this open source technology, including UltraVNC, RealVNC, and TightVNC. Each of these tools provides a different UI and a varying set of features. VNC solutions are typically self-hosted and are usually either free or relatively inexpensive.
ScreenConnect vs. VNC
How does ScreenConnect compare with VNC?
Most VNC tools require the client to be installed on both the technician and customer computer, firewall changes made, and various security changes implemented before a connection can be made. With ScreenConnect, there is around 15-30 minutes of initial setup involved. Following that, no further configurations need to be made in order to connect to a guest computer.
Customers making the change from VNC to ScreenConnect have noted that our web portal, our software UI, and the ability to work with customers without requiring firewall changes are their reasons for switching.
Why choose ScreenConnect over VNC?
ScreenConnect has been noted to have much higher quality and faster connections than VNC. ScreenConnect also packs a wide-range of features for technicians including role-based securities, video auditing and the toolbox feature.
