NordVPN has an amazing reputation for security and privacy. If you are looking to unblock sites like XVideos, then NordVPN tops the lists with its 2048-bit encryption. They offer well over 6000 servers around the world, which means it will work from any country you are in. They even have special obfuscation servers, for countries that are usually impossible to use a VPN in.

Currently, NordVPN is running a 70% deal for 3-year subscriptions, which comes out to a very reasonable $3.49/mo.

ActProxy allows you to purchase individual proxies, for much finer control over each server you use. They can be as cheap as $0.35 per proxy, depending on how many you need. They allow for both IP white listing authorization, and a proxy login/pass if you'd rather use that. They are definitely worth a look if you need an xvideos proxy.
