The Honest Truth About VPNs What VPNs Can Do Hide browsing from ISP (if no leaks) Encrypt public WiFi traffic Mask IP for basic privacy Prevent local network attacks What VPNs Can't Do Make you anonymous (use Tor) Hide you from government (with warrant) Prevent all tracking (browser fingerprinting) Protect against all threats VPN Limitations Even the best VPN: Sees your traffic (can log it) Knows your IP when connected Can be subpoenaed May have vulnerabilities Can't encrypt after exit node Conclusion A VPN is a useful privacy tool, but it's not a silver bullet. The privacy of your VPN depends on: Company trustworthiness - Do they log? Technical implementation - Do they leak? Jurisdiction - What laws apply? Your threat model - What are you protecting against?

Configure it properly, test it regularly, and understand its limitations. Your VPN should protect you—not become another threat.
