Using a VPN will prevent most kinds of DNS attacks that would redirect you to a phishing page, but a regular old page made to look like a legit one in order to trick you into entering your data can still work. Some VPNs, and most browsers, are pretty good about blocking phishing pages, but this attack still claims too many victims to be ignored. Use common sense and be sure to verify that websites are what they say they are by looking carefully at the URL and always visiting HTTPS sites.
VPN services can also be defined as connections between specific computers, typically servers in separate data centers, when security requirements for their exchanges exceed what the enterprise network can deliver. Increasingly, enterprises also use VPN connections in either remote access mode or site-to-site mode to connect -- or connect to -- resources in a public infrastructure-as-a-service environment.
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.
We also dove deeper into the desktop apps of the top-performing services. Great apps have automatic location selection, easy-to-use designs, and detailed but uncluttered settings panels. We set up each service’s Android app on a Samsung Galaxy S8 running Android 7.0 Nougat. We took into account how easy each one was to set up and connect, along with what options were available in the settings pane.
Every user is going to have slightly different VPN needs, and the best way to pick the ideal VPN service is to take careful stock of what your needs are before you go shopping. You may even find you don’t need to go shopping because home-grown or router-based solutions you already have are a perfect fit. Let’s run through a series of questions you should ask yourself and highlight how different VPN features meet the needs highlighted by those questions.
VPNs can be either remote-access (connecting a computer to a network) or site-to-site (connecting two networks). In a corporate setting, remote-access VPNs allow employees to access their company's intranet from home or while travelling outside the office, and site-to-site VPNs allow employees in geographically disparate offices to share one cohesive virtual network. A VPN can also be used to interconnect two similar networks over a dissimilar middle network; for example, two IPv6 networks over an IPv4 network.
Whereas most providers say they log nothing, that’s not always the case. Some record very little data like the day you subscribed, the amount of data you’ve consumed, and delete those logs when you end the session. Other providers log your IP address, the servers you used, and store those logs. If they’re based in the US, UK or any other country with data retention laws, they can be compelled to hand over that data to law enforcement.
When you're using a public Wi-Fi network, even a password-protected one, a VPN is your best friend. That’s because using public hotspots can be rife with hazards. From man-in-the-middle attacks to Wi-Fi sniffing, there are many different hacking methods that snoopers use to intercept your Internet traffic and steal your social media or banking passwords, files and photos.
Think about it this way: If your car pulls out of your driveway, someone can follow you and see where you are going, how long you are at your destination, and when you are coming back. They might even be able to peek inside your car and learn more about you. With a VPN service, you are essentially driving into a closed parking garage, switching to a different car, and driving out, so that no one who was originally following you knows where you went.
