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.
ProtonVPN is one of the newest VPN services, and it boasts some star-studded founding members. The company was founded at CERN, the birthplace of the internet, and grew out of the ProtonMAIL service that’s been protecting the email of activists and journalists for years. The service acts as a Swiss company and is thus free from the laws of the U.S. and the European Union. It’s also not a member of the “fourteen eyes surveillance network,” and user traffic isn’t logged and passes through privacy-friendly countries, so you needn’t worry about your true IP address being revealed.
Downloading Files: Yes, let’s be honest – many people use VPN connections to download files via BitTorrent. This can actually be useful even if you’re downloading completely legal torrents – if your ISP is throttling BitTorrent and making it extremely slow, you can use BitTorrent on a VPN to get faster speeds. The same is true for other types of traffic your ISP might interfere with (unless they interfere with VPN traffic itself.)
Free VPN Providers are more likely to log your activities and serve contextual ads while you’re connected. They’re also more likely to use your usage habits to tailor future ads to you, have fewer exit locations, and weak commitments to privacy. They may offer great features, but if logging and privacy are important to you, you may want to avoid them. However, if you just need quick, painless security while traveling on a budget, they’re a great option.
Their best plan is 1-year subscription plan: $6.99 ($83.88). While their monthly price of $11.95 is at the high end of the spectrum (and they did lose a few points for that), their yearly price of $83.88 is lower than most our contenders. And yes, they also have a full 30-day refund policy. NordVPN also offers a dedicated IP option, for those looking for a different level of VPN connection. They do offer $2.99/month (75% discount) for a 3-year plan .
