Remote access

Hi, I'm looking for assistance in setting up secure remote access for up to 5 users. The remote access solution I'm looking for is a Virtual Private Network (VPN) so that I can enable remote working in a secure environment. All five users will need to access shared files and resources in a secure manner, and also have the ability to collaborate effectively in order to get their work done. I'm looking for a remote access provider who can provide reliable, cost-effective solutions with minimal setup time, and easy to use interfaces. If you have experience with setting up secure VPNs, please get in touch and let's discuss this project further. Thanks!
