Google is full of articles claiming that a VPN will prevent ISPs from gathering metadata, but unfortunately that is not true. A VPN hides the contents of your internet traffic and your location from the outside world, but you still have to rely on your ISP’s network to get there. Strictly speaking a VPN cannot prevent an ISP from logging your location, device details, and traffic volume.

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.
The second thing that happens is that the web application you're talking to does not get to see your IP address. Instead, it sees an IP address owned by the VPN service. This allows you some level of anonymous networking. This IP spoofing is also used to trick applications into thinking you're located in a different region, or even a different country than you really are located in. There are reasons (both illegal and legal) to do this. We'll discuss that in a bit.
Hide Your Browsing Activity From Your Local Network and ISP: If you’re using a public Wi-Fi connection, your browsing activity on non-HTTPS websites is visible to everyone neraby, if they know how to look. If you want to hide your browsing activity for a bit more privacy, you can connect to a VPN. The local network will only see a single, secure VPN connection. All the other traffic will travel over the VPN connection. While this can be used to bypass connection-monitoring by your Internet service provider, bear in mind that VPN providers may opt to log the traffic on their ends.
Cost: StrongVPN offers two plan options: one month and annual. Their annual plan will give you the biggest bang for your buck, coming out to just $5.83 per month (if you pay $69.96 annually). Their monthly plan is $10. Fortunately, each tier comes with the same set of features, so you won’t get cheated out of certain levels of encryption depending on which plan you subscribe to.
HTTPS is a powerful tool that everyone should use because it helps keep sensitive browsing private at no extra cost to the people using it. But like most security standards, it has its own problems too. That little lock icon in your browser bar, which indicates the HTTPS connection, relies on a certificate “signed” by a recognized authority. But there are hundreds of such authorities, and as the EFF says, “the security of HTTPS is only as strong as the practices of the least trustworthy/competent CA [certificate authorities].” Plus, there have been plenty of news stories covering minor and even major vulnerabilities in the system. Some security professionals have worried about those least-competent authorities, spurring groups to improve on the certificate standards and prompting browsers to add warnings when you come across certificates and sites that don’t withstand scrutiny. So HTTPS is good—but like anything, it isn’t perfect.
Before you decide which best home VPN network client you want to download and install on your device, take some time to ask yourself a few questions, the most important of them being “what exactly do you need the VPN for?” For example, do you want a VPN for your Windows computer? Regardless of the platform or firmware that your devices operate on, certain aspects of a VPN are critical and should be considered before making the purchase. Regardless of why you need a VPN, unlimited access to all the Internet has to offer is of top importance when making your decision. With a VPN like Express VPN or NordVPN, you will be able to surf securely and privately. There are a number of features you might want from a VPN - unlimited number of devices, fast surfing speeds, Android and iOS apps, major VPN protocols. All are important in choosing the right VPN for you. Check out our guide to choosing the right unlimited VPN for your needs to help you decide which of the best VPNs in 2018 is right for you. 
Buffered VPN doesn't disclose much about the size of its network, but the 30-day money back guarantee means that you can take their service for a test drive and really get a feel for how well it performs for you. The company lost a few points from us because they do keep some connection information. They gained points for their client support, unlimited bandwidth, and generous number of simultaneous sessions allowed.

HotSpot Shield is a product that has had some ups and downs in terms of our editorial coverage. Back in 2016, they picked up some very positive coverage based on founder David Gorodyansky comments about protecting user privacy. Then, in 2017, a privacy group accused the company of spying on user traffic, an accusation the company flatly denies. Finally, just this year, ZDNet uncovered a flaw in the company's software that exposed users. Fortunately, that was fixed immediately.
