Though TorGuard’s support site offers in-depth information, finding specific info is harder, and the site is not as easy to follow as those for our top pick or ExpressVPN. TorGuard provides helpful video tutorials, but they’re two years old now and don’t show the latest versions of the company’s apps. As with most of the VPNs we contacted, TorGuard support staff responded to our help ticket quickly—the response to our query came less than half an hour after we submitted it on a weekday afternoon. Still, if you’re worried about getting lost in VPN settings or don’t like hunting for your own answers, IVPN is a better fit.
All VPNs have to do some kind of logging, but there are VPNs that collect as little data as possible and others that aren’t so minimalist. On top of that, some services discard their logs in a matter of hours or days while other companies hold onto them for months at a time. How much privacy you expect from your VPN-based browsing will greatly influence how long you can stand having your provider maintain your activity logs—and what those logs contain.
It is also possible (emphasis on "possible") that VPNs may be able to save net neutrality repeal. Kind of. For those who are unaware, net neutrality is the much-discussed concept that ISPs treat web services and apps equally, and not create fast lanes for companies that pay more, or require consumers to sign up for specific plans in order to access services like Netflix or Twitter. Depending on how ISPs respond to a newly deregulated environment, a VPN could tunnel traffic past any choke points or blockades thrown up by ISPs. That said, an obvious response would be to block or throttle all VPN traffic. We'll have to see how this plays out.
ProtonVPN is a superb service provided by the developers of Proton Mail. It is a secure VPN provider that lets people use the service on an unlimited basis. This makes it perfect for privately surfing the web on a daily basis. On the downside, it throttles free-users’ bandwidth. This means that the free ProtonVPN service will not provide the speeds necessary for doing data-intensive tasks such as streaming in HD. ProtonVPN is a superb VPN that many people may find useful for unblocking censored news.
Many VPN services also provide their own DNS resolution system. Think of DNS as a phone book that turns a text-based URL like "pcmag.com" into a numeric IP address that computers can understand. Savvy snoops can monitor DNS requests and track your movements online. Greedy attackers can also use DNS poisoning to direct you to bogus phishing pages designed to steal your data. When you use a VPN's DNS system, it's another layer of protection.
The main drawback with VyprVPN is their connection log policies. They keep connection logs for 30 days, but usage/activity logs are never kept. Another slight drawback is that they do not permit torrenting on their network. But on a positive note, they are very honest and straightforward about their policies, unlike some VPNs that falsely claim to be “no logs”.
There is a PPTP control connection between the IP address of the PPTP client using a dynamically allocated TCP port and the IP address of the PPTP server using the reserved TCP port 1723. The PPTP control connection carries the PPTP call control and management messages that are used to maintain the PPTP tunnel. This includes the transmission of periodic PPTP Echo-Request and PPTP Echo-Reply messages to detect a connectivity failure between the PPTP client and PPTP server. PPTP control connection packets consist of an IP header, a TCP header, a PPTP control message, and a data-link trailer and header as shown in the following figure:
PPTP - PPTP has been around since the days of Windows 95. The main selling point of PPTP is that it can be simply setup on every major OS. In short, PPTP tunnels a point-to-point connection over the GRE protocol. Unfortunately, the security of the PPTP protocol has been called into question in recent years. It is still strong, but not the most secure.
The VPN services market has exploded in the past few years, and a small competition has turned into an all-out melee. Many providers are capitalizing on the general population's growing concerns about surveillance and cybercrime, which means it's getting hard to tell when a company is actually providing a secure service and when it's throwing out a lot of fancy words while selling snake oil. In fact, since VPN services have become so popular in the wake of Congress killing ISP privacy rules, there have even been fake VPNs popping up, so be careful. It's important to keep a few things in mind when evaluating which VPN service is right for you: reputation, performance, type of encryption used, transparency, ease of use, support, and extra features. Don't just focus on price or speed, though those are important factors.
