What is the benefit of using a virtual private network (VPN) with 3CX?

Using a virtual private network (VPN) with 3CX primarily provides secure remote access to the 3CX server. This is essential for businesses that have employees working remotely or from different locations. A VPN creates a secure tunnel over the internet between the remote user and the company's server, ensuring that sensitive data, such as voice calls and communication protocols, are encrypted and protected from potential interception or eavesdropping.

Additionally, when using a VPN, users can connect to the 3CX server as if they were physically on the same local network. This enhances the overall security of VoIP communications, as the data is safeguarded during transmission, which is particularly important in a landscape where cyber threats are prevalent. Ensuring that only authenticated and authorized users can access the 3CX system is a crucial aspect of maintaining organizational security, and a VPN effectively facilitates this requirement.
