Why it matters
"Get a VPN" has become generic internet safety advice, and a whole industry markets VPNs as a cloak of invisibility that makes you anonymous and unhackable. That framing is wrong, and believing it is its own risk: people take real chances online thinking a VPN has them covered when it does nothing about the actual threat. A VPN is a genuinely useful, narrow tool — it hides your traffic from the network you are on and from your internet provider — and knowing exactly where that usefulness starts and stops is what lets you decide when it is worth it, when it changes nothing, and what you are…
What you'll learn
- understanding what a VPN encrypts and hides
- separating VPN marketing from reality
- knowing what a VPN does NOT protect (tracking, logins, malware, phishing)
- reasoning about the ISP-to-provider trust shift
- evaluating no-logs claims and provider jurisdiction
- deciding when a VPN genuinely helps
- choosing a VPN or self-hosting one
