In addition to blocking malicious sites and ads, some VPNs also claim to block malware. We don't test the efficacy of these network-based protections, but most appear to be blacklists of sites known to host malicious software. That's great, but don't assume it's anywhere near as good as standalone antivirus. Use this feature to complement, not replace, your antivirus.
Some VPNs offer great service or pricing but little to no insight into who exactly is handling them. We considered feedback from security experts, including the information security team at The New York Times (parent company of Wirecutter), about whether you could trust even the most appealing VPN if the company wasn’t willing to disclose who stood behind it. After careful consideration, we decided we’d rather give up other positives—like faster speeds or extra convenience features—if it meant knowing who led or owned the company providing our connections. Given the explosion of companies offering VPN services and the trivial nature of setting one up as a scam, having a public-facing leadership team—especially one with a long history of actively fighting for online privacy and security—is the most concrete way a company can build trust.
The free tier gives you the Windows, Mac, iOS, Android and Amazon Fire TV/Firestick client software (and the beta Linux software, should you wish to try it); the Windflix feature to (try to) watch U.S. or U.K. Netflix streams; the Chrome, Firefox and Opera Windscribe browser extensions to block ads and trackers; a separate firewall built in to the Windows and macOS clients; and the ability to connect to VPN servers in 11 countries, mostly in Europe and North America.
