Some virtual networks use tunneling protocols without encryption for protecting the privacy of data. While VPNs often do provide security, an unencrypted overlay network does not neatly fit within the secure or trusted categorization.[citation needed] For example, a tunnel set up between two hosts with Generic Routing Encapsulation (GRE) is a virtual private network, but neither secure nor trusted.[24][25]
As we said, KeepSolid VPN Unlimited is also good value, if you’re prepared to dig deep. Paying £76.45 for three years use is equivalent to paying £2.12 a month, or, if you’re really made of money, then £152.92 will net you a lifetime subscription. The standard monthly price of £7.64 doesn’t compare as well, but £45.88 for 1 year (equivalent to £3.82 a month) is slightly better than others.
Chosen as one of Mashable's top three for staying anonymous online, NordVPN is a choice backed by much of Reddit. It's made for fast streaming and torrenting, P2P and non P2P options, and is one VPN that can actually bypass the American Netflix block anywhere in the world. Plus, a single NordVPN login can be used on up to six devices simultaneously, so sharing the perks and splitting the price is a major bonus for savvier internet users. Reddit user ambillop writes:

Based in Switzerland and owned by the US company “Gold Frog”, VyprVPN is quite similar to Buffered. It has quickly gained momentum in the marketplace of VPN providers. The VPN offers exceptionally fast speeds, remarkable unblocking features, and huge server database. It also offers advanced technologies, like Chameleon Technology and the famous VyprDNS.
Giving a tough competition to other budget-friendly providers, Surfshark has made an impressive entry into the market. We took around 10 hours to review the service properly, and needless to say, we were quite impressed. The provider is based in the British Virgin Islands (a VPN-friendly jurisdiction). BVI is free of all sorts of data retention laws, so you can rest assured of your data being secure.
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.
