Cannot Versus Will Not: Two Kinds of VPN Guarantee
Some guarantees are enforced by architecture, others only by intention. Sorting a provider's promises into the two classes predicts what survives pressure.

What Turning On a VPN Today Does Not Undo
A VPN takes effect from the moment it is on. It cannot retract records that already exist, and the moment you switch it on is itself observable.

How Websites Tell You Are Using a VPN
Address reputation, registration data and traffic patterns give it away. Why sites care, what they do about it, and why extra verification follows.
-
What Does a VPN Actually Protect Against?
It hides your traffic from the local network and your ISP, and hides your IP from sites you visit. It does not make you anonymous. The honest scope.

What Survives a Tunnel: Traffic Metadata
Encryption hides content, not shape. Packet timing, sizes and volume remain visible, and they reveal more than most people expect. What that implies.

Your bank's connection is already encrypted, so a VPN adds little on a trusted network — and can trigger extra verification. When it does help.
