About this primer

Why it was written

Most writing about VPNs is written by people selling them. The remainder is written for network engineers. Between the two sits the reader who simply wants to know what this technology does, what it cannot do, and how to choose sensibly. VPN Route is for that reader — a short, calm text with no affiliate links and no preferred vendor.

Editorial distance

• No provider is recommended, named as superior, or linked with any referral arrangement.
• Claims are grounded in protocol behaviour and public documentation rather than vendor marketing.
• Corrections are applied when shown wrong; the edition date moves with them.
• No software is distributed here — the primer describes technology, it does not carry it.

Scope

Six sections: what a tunnel changes, how protocols differ, honest limits, a provider checklist, everyday security habits, and the questions readers actually send. If a seventh earns its place, it will be added at the same standard.
