Checks common privacy exposure signals such as IP, DNS, WebRTC and IPv6.
Open Leak TestAbout Denys Shchur
I build practical VPN, privacy and streaming diagnostic resources for users who want to understand what is actually happening with their connection before they make decisions.
My main projects are SmartAdvisorOnline and VPN World. SmartAdvisorOnline focuses on hands-on tools, troubleshooting guides and technical explainers. VPN World is a multilingual privacy and VPN knowledge project for users in different regions.
What I work on
- VPN leak testing guides covering IP, DNS, WebRTC and IPv6 signals.
- Streaming VPN troubleshooting for Netflix, Hulu, Disney Plus, BBC iPlayer and similar platforms.
- Speed and stability testing, including VPN speed checks and connection quality signals.
- Router-level VPN guides, public Wi-Fi security and practical privacy checklists.
- Structured, multilingual VPN content for users in different countries and search contexts.

Open GitHubHow I approach reviews and guides
- I separate privacy, speed and streaming problems instead of treating every VPN issue as the same thing.
- I prefer practical tests and user scenarios over generic marketing claims.
- I explain limitations clearly, especially when a tool can only show the current state of a connection.
- I keep recommendations tied to real use cases, not just brand popularity.
Useful starting point: if you are unsure whether your VPN is working properly, start with the VPN Leak Test. If streaming is the issue, use the Streaming Test. If performance is the issue, use the Speed Test.
