I'm using My IP.io and pretty impressed with ther dedicated IP service, which gives you your own static IP for nder 6 buck a month.
The level of security is up to date, they support all the latest security protocols including SSTP, PPTP, IPSec, L2TP, SSTP, and OpenVPN.
Another perk I've discovered when challenged to set a master VPN account for my team is their Business plan.
The level of sophistication depends on the number of accounts and/ devices you need.
The business VPN can consolidate all your team’s accounts into one master account, a convenient scenario in terms of having control, management and payment. They can allocate a whole subnet, so that you won’t be constrained as to having to whitelist multiple IPs or engineer a custom solution in which they install a LDAP server. You will be given a password manager and VPN server and you’re free to run your own network to your preference.
The business VPN solution allows multiple people to be logged in and proxying through a single IP address at one time, simultaneous connection for all on multiple devices, editing and monitor access, from a single, easy-to-use central admin area.
To get started in full big business connectivity way, just connect with My IP.io and you’ll be assigned an account manager that will guide you through the whole installation process and assist you each step of the way for the whole period of your subscription.
