The Asked

Chapter 02 — Technology & Internet

Do I actually need a VPN?

For most people, no. HTTPS already encrypts the contents of your browsing. A VPN helps in three real cases: using untrusted public Wi-Fi for sensitive logins, bypassing geographic restrictions, or hiding your IP from the sites you visit (not your ISP, who sees the VPN instead).

Follow-up questions

Are free VPNs safe?

Usually not — many sell your browsing data or inject ads. If you're going to use one, pay for it.

Does a VPN make me anonymous?

No. Cookies, account logins, and browser fingerprinting still identify you. A VPN hides your IP, not your identity.

Will it slow down my internet?

Yes, typically 10–30%. Pick a server geographically close to you to minimize it.

Does a VPN hide me from my ISP?

From seeing which sites you visit, yes. From knowing you're online, no.

Which VPN is trustworthy?

Pick a provider with independent audits (Mullvad, IVPN, ProtonVPN). Avoid free VPNs — they monetise your traffic.

Does a VPN slow the internet?

By 10–30% typically, more if the server is far. Nearby servers with WireGuard protocol minimise the hit.

Can my employer see through a VPN?

If it's a work laptop, likely yes — corporate MDM sees traffic before it hits the VPN.

Should I leave a VPN on all the time?

Only if you have a specific threat model. For most people, on-demand for public Wi-Fi is enough.
