Despite common marketing exaggerations, a VPN is ineffective at:
- Achieving absolute untraceability or total anonymity.
- Preventing data profiling when logged into Google, Meta, or social platforms.
- Halting device fingerprinting through modern browser trackers.
- Securing devices against compromised passwords or local spyware.
- Masking your Android smartphone hardware GPS coordinates.
- Preventing credential leaks caused by third-party database breaches.
- Protecting against targeted social engineering scams.
Do not rely on any VPN to solve every digital security challenge.
However, a trustworthy and audited VPN is very effective at:
- Encrypting traffic so cellular carriers and ISPs cannot monitor, log, or sell your browsing history.
- Encrypting DNS queries so network providers cannot inspect the hostnames you visit.
- Shielding data packets on untrusted public Wi-Fi networks to prevent Man-in-the-Middle attacks.
- Concealing your genuine public IP address from external servers and platforms you access.
- Overcoming geographic content restrictions, censorship firewalls, and arbitrary ISP blocks.
