Each of these VPN scenarios can be deployed to provide connectivity over a public network, such as the Internet, or over a private intranet. VPN connections can also be deployed in an extranet scenario to communicate securely with business partners. An extranet functions as an intranet that can be securely shared with a designated business partner.
Servers – The number of servers and geographical distribution of these servers is another important factor that determines the quality of a VPN. The greater the server network, the fewer problems you are likely to encounter such as overcrowded servers and downtime. A strong server infrastructure signifies a high standard of VPN performance standard.
IPVanish wasn't the top performer in our 2017 round of testing, falling in about the middle of the pack. But it was one of the most reliable VPN services, connecting smoothly and staying connected every time we used it. IPVanish has excellent client software, although you can connect to the company's servers manually, and a decent array of about 850 connection points in 50 countries. However, its subscription price is kind of high, and its U.S. base may be a negative for some potential customers.
EAP-TLS is an IETF standard (RFC 2716 in the IETF RFC Database for a strong authentication method based on public-key certificates. With EAP-TLS, a client presents a user certificate to the server, and the server presents a server certificate to the client. The first provides strong user authentication to the server; the second provides assurance that the VPN client has reached a trusted VPN server. Both systems rely on a chain of trusted certification authorities (CAs) to verify the validity of the offered certificate.
We really like PrivateVPN’s user-friendly desktop client but the mobile apps leave a lot to be desired when it comes to configurable options, although this probably won’t affect the majority of users. It can be made to work in China at a push, however there are much more reliable options available for that purpose. In terms of striking a balance between privacy and performance, PrivateVPN does a brilliant job.
Required only when the VPN server is acting as a VPN client (a calling router) in a site-to-site VPN connection. If all traffic from TCP port 1723 is allowed to reach the VPN server, network attacks can emanate from sources on the Internet that use this port. Administrators should only use this filter in conjunction with the PPTP filters that are also configured on the VPN server.
Whether you’re you’re sick of your ISP throttling your connection, you want to secure your browsing sessions while on the road, or you just want to download whatever the heck you want without the man on your back, there’s no substitution for a securely deployed Virtual Private Network. Now that you’re armed with the knowledge necessary to pick a good VPN (and with three solid recommendations at that), it’s time to secure your internet traffic once and for all.
In such scenarios, you don’t need a beastly VPN provider with massive bandwidth to secure your email, Facebook, and web browsing activities. In fact, the same home VPN server model we highlighted in the previous section will serve you just as well as a paid solutions. The only time you might consider a paid solution is if you have high-bandwidth needs that your home connection can’t keep up with (like watching large volumes of streaming video through your VPN connection).
When a VPN server is in front of a firewall and connected to the Internet, inbound and outbound packet filters on the VPN server need to be configured to allow only VPN traffic to and from the IP address of the VPN server’s Internet interface. Use this configuration if the VPN server is in a perimeter network, with one firewall positioned between the VPN server and the intranet and another between the VPN server and the Internet.
We’ll get to the implications of a VPN’s location in a moment, but first, let’s get back to our secure tunnel example. Once you’re connected to the VPN and are “inside the tunnel,” it becomes very difficult for anyone else to spy on your web-browsing activity. The only people who will know what you’re up to are you, the VPN provider (usually an HTTPS connection can mitigate this), and the website you’re visiting.
There are lots of good reasons why you need a VPN. The most obvious is that routing your traffic through an encrypted tunnel means it is much harder for people on the same network as you—say, at a coffee shop—to snoop on your activities. If the person who owns the network is a bad guy, spying on your activity and hoping to snatch a password or two, they'll also be foiled by a VPN. This also protects against a lot of other scary scenarios, like DNS poisoning. With that kind of attack, you type in a legitimate website URL but are forwarded to a phishing site designed to steal your information.
CyberGhost’s popular free tier might not offer amazing speeds, but its paid Pro tier is a real contender. It proved to be both quick and consistent in our speed tests. An “extra speed” feature can be toggled before you connect for an extra boost. Setup and use are novice-friendly, and live chat with customer support is available if you need a hand. Military grade encryption ensures all your data is safely tunneled to the VPN server, and CyberGhost does not store any logs of user activity or other identifiers.
IPVanish is one of the few providers that owns and operates its own network of servers, rather than rents servers out from third parties. This guarantees customers a sturdy, uncongested connection and better privacy. The IPVanish apps include an auto-select feature that connects you to the fastest available server in a given country or city. You can monitor upload and download speed in real time. Traffic is protected by 256-bit AES encryption, and a zero logs policy ensures that no usage data is ever recorded. A single subscription allows users to connect up to five devices at once. IPVanish is particularly popular with Kodi users due to its fast speeds, great privacy features and because it is easy to install on most devices popular with Kodi users including the Amazon Fire Stick.
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.
