A recent analysis of over 800 free mobile VPN apps revealed significant security flaws, with many apps leaking personal data and requesting excessive permissions. Zimperium zLabs found that these vulnerabilities pose risks not only to individual users but also to organizations with BYOD policies, as these apps can compromise sensitive business data. Concurrently, a survey by Proton indicated that 85% of mobile VPNs in the US contain trackers, with a quarter actively tracking users' locations. The findings raise serious concerns about the integrity of VPN services, particularly those owned by companies in high-risk jurisdictions, such as China. Despite the widespread use of VPNs for privacy protection, users may be unknowingly exposing themselves to greater risks.
