A VPN (Virtual Private Network) connects a PC or laptop over the Internet to the office network, allowing the remote user to work as if they were sitting at their desk in the office. Typically, setting up a VPN requires considerable technical knowledge, including reconfiguring the office firewall, configuring the VPN server, and protecting the entire stack.
Once the VPN server is up and running, it needs to be monitored (to ensure nothing suspicious) and maintained with the latest security fixes from the VPN provider.
Setup a VPN services offers all the functionality of a VPN server. It also eliminates the hassle, monitoring, and maintenance problems.

To set up a VPN provided as a service, you will need to visit the provider's website, register online, and download some software to the office network system. This software connects the office network to a VPN service over the internet without having to change your firewall.
By not changing your firewall, you eliminate a potential point of attack for hackers scanning your firewall to identify vulnerabilities. Once the office network is connected, you can add users to the service and set up their computers for VPN access.
More modern VPN services allow remote users to set up access to the office so remote users can work on their applications and files as if they were in the office within minutes of signing up.
