There is no one standard form of encryption used by the military. “Our survey results suggest that even users with high security and privacy expertise express that they feel safe with a VPN, suggesting that VPNs are successful in their marketing efforts,” Ensafi says.Īs another example of how VPNs can make overly broad claims, a number of them say they provide “military-grade encryption.” Many security professionals say that this term should be a red flag for consumers, because it doesn’t really mean anything. When Ensafi and her colleagues surveyed more than 1,200 VPN users, they found that people placed too much faith in the technology to keep them safe. And your data can be compromised through phishing, malware, and various other methods that VPNs can’t address. However, advertisers and governments are both able to track people in many ways not involving their IP addresses, which is what VPNs obfuscate. “Hyberbolic claims and overpromising by VPNs are not only unethical but also dangerous because it can lead to fostering a false sense of security,” says Reethika Ramesh, a graduate student in Ensafi’s lab and lead researcher at VPNalyzer.įor example, many VPNs have promised complete anonymity or untraceability, or protection from advertisers, governments, and criminals. They can also give VPN users a false sense of security if they don’t realize that the protections offered are not comprehensive. We found that 12 out of 16 of the VPNs we looked at either inaccurately represented their products and technology, or made hyperbolic or overly broad claims about the kinds of protection they provide their users. These claims, combined with a constant stream of news reports about security breaches, can lead people to worry more than necessary about banking online or visiting websites that are already encrypted using HTTPS. With a misalignment of incentives between users and VPN providers, this can result in bad actors exploiting and preying on users’ trust,” says Roya Ensafi, assistant professor at the University of Michigan and principal investigator of VPNalyzer, an interdisciplinary research project that aims to analyze the VPN ecosystem. “By using a VPN, a user essentially transfers trust from their network provider to the VPN provider. Signing up for a VPN that’s not doing a great job can make your private data less safe, not more. ![]() There’s a lot of hyperbole and unrealistic promises to be found in some VPNs’ marketing-and if you take all of it at face value, you might think you have more protection than you really do. We also looked at all the consumer-oriented language on the VPNs’ websites. In brief, we looked to see whether security best practices were being used whether data was being leaked, making it vulnerable to criminals and what the privacy policies said about how personal data might be used. Our analysis was detailed, and a full report is posted on the CR Digital Lab site. ![]() ![]() But more broadly, we confirmed what many security experts have said for years: The industry’s privacy and security practices often don’t live up to its marketing. When CR tested the privacy and security of 16 VPN services running on Windows 10, we identified what we consider to be the three best VPNs for most consumers. It can be tricky to pick a good VPN, which is important because you are entrusting it with your personal data. The catch is that the VPN itself has access to all of this data, instead. Using a VPN can also prevent your mobile network and internet service provider from seeing and tracking the internet domains you visit. You download some software onto your device, and when you’re logged in, the VPN can offer some protection when you’re using free WiFi at an airport, library, or coffee shop by making it harder for network administrators to see what you do online. Whether you’re working from home or just spending more time online, you may have considered using a virtual private network, or VPN, to boost your privacy and security.Ī VPN is a service that routes all of the data sent to and from your computer or phone through the VPN provider’s own servers, or servers it rents.
