We ran the parts of a professional VPN security audit that can be done from the outside on SingLink VPN: transport-layer configuration, the App Store record, and the protocol, transparency, logging and jurisdiction posture read from its own documents. The transport layer is modern. The security-critical core, the protocol and the independent-audit trail, is either unverifiable by design or absent. Here is exactly what checks out, what does not, and what no outsider can confirm.

Guide
A technical tour of the open-source protocols behind modern VPNs (WireGuard, OpenVPN, IPsec/IKEv2, OpenConnect, SoftEther) and the circumvention layer built on top of them (Shadowsocks-2022, VLESS+REALITY, Trojan, Hysteria2, TUIC, NaiveProxy): how they differ, which is genuinely faster or safer, and, with dated and cited sources, how each holds up against China's Great Firewall and Russia's TSPU as of mid-2026.

Guide
“Based in a privacy-friendly country” is a line on almost every VPN's homepage. Jurisdiction is real and worth understanding, but the marketing version glosses over the parts that actually decide whether it protects you. A short, honest guide to what a VPN's country of registration does and doesn't buy you.

Almost every VPN says it keeps no logs. The phrase is doing a lot of work and most of it is unverified. Here is how to read a no-logs claim: what the words commit a provider to, what they leave out, and the three things that turn a marketing line into evidence.

A blank on this site is an admission about us, not a verdict about the provider. A dimension we hold no evidence for is dropped from the average, never scored as zero, because punishing a provider for a gap in our research would reward whichever providers we researched least.

A server list is a claim; the speed of light is not. Because light in fibre covers about 200 km every millisecond, a round-trip time sets a hard ceiling on how far away a machine can be. When the ceiling is smaller than the distance to the city on the label, the label is wrong.

“Independently audited” is the industry's favourite adjective and its least informative one. Our transparency score does not count audits; it reads them. A single full report a reader can open outweighs a shelf of summaries nobody outside the provider has seen.

Every score on this site is an interval, not a point. Ranking follows from those intervals by dominance, a provider ranks above another only when its guaranteed minimum clears the other's best possible maximum. On today's corpus that relation is empty, so we print one honest tie rather than a manufactured 1-2-3.
