..Our research shows that VPN websites are disappointingly very similar to – and sometimes worse than – other popular websites. Of the 114 VPNs we analyzed, 102 websites had trackers on them, with 26 websites having 10 or more trackers. A lot of these trackers involve third parties that don’t have the best reputation for respecting user privacy, which can be detrimental for the user.
Even worse, they’re using session replay scripts: nearly 1 in 4 VPN websites used them to record video of how each user goes around their website, what they click, what they search for, and much more.
Luckily, the situation isn’t all bad: there are 13 websites that have absolutely no trackers on them, and 48 websites have 4 or fewer trackers on them.
