Usually, it's the free services that throttle your usage in these ways. Some paid services will offer a trial, where you can transmit up to a certain data cap before being asked to sign up as a paying customer. That's actually pretty cool, because it gives you a chance to try out the performance of their service before paying, but it also gives the vendor a chance to make the money necessary to operate the service.
It's also notable that ExpressVPN is able to gain access to Netflix, which some (like PureVPN) are not able to do. Like PureVPN, ExpressVPN is one of the best for getting around roadblocks in China (though there are only servers in 94 countries), and has up to 256 bit encryption. Get one month for $12.95, six months for $9.99/month, or a one-year subscription for $8.32/month. You would be paying around $10 more per month compared to any other VPN, but the quality is definitely there — and if you're really not happy, you can get your money back within the first 30 days. Another cool thing: You can pay with Bitcoin.
VyprVPN offers an okay speed, despite being rather slow compared to all previously discussed VPNs in this article. Torrenting is technically possible but VyprVPN is not built for that. If you break any copyright laws via downloading torrents for say a movie that is still sold in cinemas, your VyprVPN account will get suspended with no refund eligibility. Support is via a ticket system that is somewhat slow, especially around holidays. Most businesses will have to keep that in mind.
No reputable VPN service logs any kind of user activity, unlike your internet service provider, which can easily log every website you visit by storing all your DNS requests sent in cleartext. The only VPN on this list that maintains 24 hours worth of basic connection logs (no activity) is VPN.ac, and they clearly state their reasons (security) for doing so. There have been shady VPNs that have cooperated with government agencies, such as PureVPN (see logging case) and I do not recommend these providers.
As part of our research, we also make sure to find out where the company is based and under what legal framework it operates. Some countries don't have data-retention laws, making it easier to keep a promise of "We don't keep any logs." It's also useful to know under what circumstances a VPN company will hand over information to law enforcement and what information it would have to provide if that should happen.
And they manage to do all of this without sacrificing performance, offering one of the fastest download speeds (83 Mbps out of 100 Mbps) and the best 24/7 customer support in the industry. The only downside? It’s a little on the pricey side, with monthly plans starting between $6.67 and $12.95/mo. But it’s a small price to pay for excellent performance in almost every category.
