Secondly, ISPs usually do not block VPNs since many organizations use them legally. Just consider: they connect you to the needed sites directly, so your speed is limited only by physical properties of your Internet connection (and your data plan). The Tor architecture has no safeguards to prevent this type of scenario.Īll the aforementioned flaws are absent in high-quality, reliable VPN services. Moreover, nothing prevents anyone from setting up his own Tor exit node for malicious purposes and intercept all Tor traffic going through it, spying on users. It allows both authorities as well as hackers read it rather easily. Tor does not carry out end-to-end encryption, so your traffic is not encrypted at the exit node.
Some Internet service providers actively search out Tor relays and block them which makes connecting to sites very difficult and/or slow, especially in some countries like China. By the way this is also the reason why Tor is not recommended for streaming video, especially geo-restricted one. Since its work is based on routing your Internet traffic through its own network of so called relays rather than directing it by the most straight way, you wait for a page to load longer than in a regular browser. Why internet speed in Tor browser is lowĪnother Tor’s problem is a very low speed. Unfortunately, Tor just does not prevent this type of leaks, and its users usually do not know about it. At the same time, WebRTC saves and transmits to the Internet the users’ IP addresses that are easily to be tracked by strangers. This technology allows establishing a direct peer-to-peer audio and video connection between two users using just a browser. This is one of the most problematic leak sources in modern browsers.
The first problem has to do with WebRTC (Web Real-Time Communication) technology. Let us consider some differences between the two. But this does not mean that they perform it equally well. The TOR browser and Virtual Private Networks (VPN) were created with the same goal in mind – anonymous and secure Internet work.
