While you're connected to a VPN, all your network traffic passes through this protected tunnel, and no one—not even your ISP—can see your traffic until it exits the tunnel from the VPN server and enters the public internet. If you make sure to only connect to websites secured with HTTPS, your data will continue to be encrypted even after it leaves the VPN.
We used to advise people to do banking and other important business over their cellular connection when using a mobile device, since it is generally safer than connecting with a public Wi-Fi network. But even that isn't always a safe bet. Researchers have demonstrated how a portable cell tower, such as a femtocell, can be used for malicious ends. The attack hinges on jamming the LTE and 3G bands, which are secured with strong encryption, and forcing devices to connect with a phony tower over the less-secure 2G band. Because the attacker controls the fake tower, he can carry out a man-in-the-middle attack and see all the data passing over the cellular connection. Admittedly, this is an exotic attack, but it's far from impossible.
Internet Protocol Security (IPsec) was initially developed by the Internet Engineering Task Force (IETF) for IPv6, which was required in all standards-compliant implementations of IPv6 before RFC 6434 made it only a recommendation. This standards-based security protocol is also widely used with IPv4 and the Layer 2 Tunneling Protocol. Its design meets most security goals: authentication, integrity, and confidentiality. IPsec uses encryption, encapsulating an IP packet inside an IPsec packet. De-encapsulation happens at the end of the tunnel, where the original IP packet is decrypted and forwarded to its intended destination.
VPN services, while tremendously helpful, are not foolproof. There's no magic bullet (or magic armor) when it comes to security. A determined adversary can almost always breach your defenses in one way or another. Using a VPN can't help if you unwisely download ransomware on a visit to the Dark Web, or if you are tricked into giving up your data to a phishing attack.
Like most well-known VPN companies, IVPN supports a variety of privacy groups and causes. Pestell told us he worked with the Center for Democracy & Technology to improve trust in VPNs with a handful of transparency initiatives before they were announced. Neena Kapur of The New York Times (parent company of Wirecutter) information security team noted that IVPN’s leadership transparency and its relationship with CDT were significant pluses that contributed to its trustworthiness. Pestell was also the only representative we spoke with to offer to arrange for one of our experts to audit the company’s server and no-logging policies.1 We cover trust issues with VPNs at length elsewhere in this guide, but we believe that IVPN takes an active role in protecting its customers’ privacy and is not a dude wearing a dolphin onesie.
One of the most popular VPN services in the market, HideMyAss has a myriad of features that are sure to attract anyone who wants online anonymity. It uses a variety of servers that work with any operating system or mobile device. Aside from PPTP and OpenVPN protocols, the service supports L2TP, which is more difficult to block. Ideal for getting around censorship and firewalls.
With VPNs you can access streaming services which are usually blocked to overseas viewers. You can do this by simply connecting to a VPN server in the appropriate country. Unsurprisingly, both Netflix and BBC iPlayer attempt to block VPN users. These blocks are often ineffective, and many providers have found ways around them. For more information about unblocking the most common services see our VPN for Netflix and VPN for BBC iPlayer guides.
Mobile Apps: If you’re going to spend money on a VPN service provider (or even if you use a free one, frankly), you should be able to get a consistent experience across all of your devices. Most prominent providers offer desktop and mobile solutions for individual users, and while corporate and school networks may be a bit behind the curve here, they’re catching up too. Make sure you don’t have to use two different VPNs with two different policies and agreements just because you want to secure your phone along with your laptop.
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.
Logging: When you connect to a VPN, you’re trusting the VPN service provider with your data. Your communications may be secure from eavesdropping, but other systems on the same VPN—especially the operator—can log your data if they choose. If this bothers you (e.g., you’re the privacy/security advocate or the downloader), make absolutely sure you know your provider’s logging policies before signing up. This applies to location as well—if your company doesn’t keep logs, it may not matter as much where it’s located. (There’s a popular rumor that US-based VPN providers are required to log, in case the government wants them. This isn’t true, but the government can always request whatever data they have if they do log.) For a good list of VPN providers that don’t log your activities when connected (and many that do), check out this TorrentFreak article.
Welcome to the CNET 2019 Directory of VPN providers. In this directory, we're taking a look at a few of the very best commercial VPN service providers on the Internet like CyberGhost, IPVanish, Hotspot Shield, Private Internet Access and others. Rather than looking at the wide range of free providers, which often have a lot of limits (and dubious loyalties), we are looking at those vendors who charge a few bucks a month, but put your interests first, rather than those of shadowy advertisers and sponsors. Our VPN rankings are based more than 20 factors including number of server locations, client software, dedicated and dynamic IP, bandwidth caps, security, logging, customer support and price.
