Obfuscation can protect you from being discovered by Netflix, yes. Obfuscated servers are a type of VPN server designed to conceal the fact that you are using a VPN to reroute your data. This enables VPN usage in situations where services like Netflix prohibit it. In addition, these servers employ various methods, including encryption and other techniques, to make it extremely difficult for Netflix or any other streaming provider to determine whether or not you are actually using a VPN.
The most reliable method for getting around VPN blocks and watching Netflix, Amazon Prime, Hulu, and BBC iPlayer from anywhere is to use an obfuscated server provided by your VPN service. It’s also the best method to keep your VPN traffic hidden from your Internet service provider or any other prying eyes.
