Security guide
A practical guide to choosing a reputable VPN — what they protect, what they cannot fix, and why Proton VPN, Mullvad, and NymVPN stand out for privacy-conscious users.
A Virtual Private Network creates an encrypted tunnel between your device and a VPN server. Traffic leaving your device is encrypted, and websites see the VPN server's IP address instead of yours — reducing what your ISP, the café Wi‑Fi operator, or someone on the same network can observe.
Your device talks directly to the website. The Wi‑Fi operator and ISP can see connection metadata — and on hostile networks, traffic may be intercepted.
Traffic is wrapped in encryption to the VPN server first. Observers on the local network see encrypted packets — not which sites you visit.
VPNs are useful, but not a magic invisibility cloak — especially when sharing secrets.
For one-time secrets — passwords, seed phrases, API keys — use end-to-end encrypted sharing like PrivateNote. A VPN protects the pipe; it does not protect what you paste into email, Slack, or SMS.
You do not need one 24/7 unless your threat model calls for it — but these are the situations where a reputable VPN earns its place.
Public Wi‑Fi
Airports, hotels, cafés
Travel
Foreign networks & roaming

Research & journalism
Three privacy-first VPNs from reputable teams — pick based on Swiss law, anonymous signup, or mixnet-level routing.
Swiss privacy law · audited no-logs · Proton ecosystem
Built by Proton AG — the team behind Proton Mail. Open-source apps, independent audits, Secure Core routing, and optional Tor-over-VPN.
No email · account number only · cash & crypto
Swedish VPN with anonymous account numbers, flat pricing, and payment options that keep your identity separate from your subscription.
Mixnet routing · beyond standard tunneling
Adds mixnet technology on top of VPN encryption — breaking and reordering packets to resist traffic analysis, not just hide your IP.
| Best for | Proton VPN | Mullvad | NymVPN |
|---|---|---|---|
| Privacy jurisdiction | Switzerland | Sweden | Decentralized mixnet |
| Signup | Email account | Random account # | Standard account |
| Stand-out feature | Secure Core + Tor | Cash/crypto payment | Mixnet routing |
| Ideal user | Proton ecosystem fans | Maximum signup anonymity | Traffic-analysis resistance |
A VPN protects your connection. PrivateNote protects the secret itself — encrypted in your browser before upload, self-destructing after one read.
