If HTTP browsing is a postcard that anyone can read as it travels along, HTTPS (HTTP Secure) is a sealed letter that gives up only where it’s going. For example, before Wirecutter implemented HTTPS, your traffic could reveal the exact page you visited (such as https://thewirecutter.com/reviews/best-portable-vaporizer/) and its content to the owner of the Wi-Fi network, your network administrator, or your ISP. But if you visit that same page today—our website now uses HTTPS—those parties would see only the domain (https://thewirecutter.com). The downside is that HTTPS has to be implemented by the website operator. Sites that deal with banking or shopping have been using these types of secure connections for a long time to protect financial data, and in the past few years, many major news and information sites, including Wirecutter and the site of our parent company, The New York Times, have implemented it as well.
If VPN connections get blocked by your network because of strict network management or government censorship, TorGuard offers a “stealth” connection to avoid deep packet inspection. Specifically, TorGuard uses Stunnel (a clever portmanteau of SSL and tunnel) to add an extra layer of encryption and make your traffic look like normal, secure Web traffic. If you’re having connection issues, you can enable Stunnel with a checkbox on the main application window, but only if you select TCP from the protocol list. (Otherwise, the box is unclickable, with no explanation as to why.)
HotSpot Shield is a product that has had some ups and downs in terms of our editorial coverage. Back in 2016, they picked up some very positive coverage based on founder David Gorodyansky comments about protecting user privacy. Then, in 2017, a privacy group accused the company of spying on user traffic, an accusation the company flatly denies. Finally, just this year, ZDNet uncovered a flaw in the company's software that exposed users. Fortunately, that was fixed immediately.
