Perfect for bypassing geoblocking, local censorship, and regaining access to the global internet. This makes it nigh-impossible to detect, and in turn, your connection won’t get blocked. The traffic going through it will always show up as HTTPS. Cryptography experts hold AES-256 in high regard despite some speed issues, it doesn’t hinder protocol performance in a significant way.Īnother critical piece of the puzzle is the aforementioned port 443. Specifically, its latest 3.0 version, which offers the highest level of security thanks to 256-bit AES encryption. The reason SSTP is so secure lies in its SSL-reliant protocol. To ensure this, the network will use so-called certificates: Encryption requests that travel between two endpoints. As previously mentioned, the SSTP port is 443, which also matches HTTPS, meaning they share the same level of security and encryption. This VPN protocol has proven to be one of the more secure ones. Additionally, this protocol requires server authentication whenever establishing a connection and, optionally, going through the same process on the client side. This ensures data integrity and encryption for all the traffic that occurs while the VPN connection remains active. In the case of SSTP, a VPN app will transport traffic under a Point-to-Point Protocol (PPP) with an added layer of SSL/TLS protection. This is why it needs a tunneling protocol to create a secure connection between the client app and VPN server. Your VPN app needs to pass the bandwidth through some tunnels to properly encrypt it, thus ensuring your security when you’re online. It uses the same port (port 443) as SSL/TLS and can surpass the limitations of traditional firewalls, like problematic port forwarding. The technology is based on SSL/TLS certificates, encrypted data, and secure keys. You can see it in your OS’s process manager as an SstpSvc.dll file. Since it has replaced PPTP in Microsoft products, the SSTP VPN protocol has been present in all versions of the Windows OS, including the recently launched Windows 11. For example, if your VPN provider uses PPTP, services like Netflix could easily block you from accessing content available outside of your region. While pretty powerful, PPTP’s encryption is still hackable and also detectable by content providers. The tech giant from Redmond launched this protocol alongside its Windows Vista operating system as a replacement for the PPTP protocol. The Secure Socket Tunneling Protocol, or SSTP for short, is a protocol created and developed by Microsoft. Many different protocols are available today for data tunneling through a VPN, with SSTP standing out as one of the most secure choices.īut what is it, and how does it work? Do you even need it for regular VPN use, or is it a mandatory protocol? Read on to find out. You’ll want several safety layers, so you’ll use IP masking through a VPN. One can’t have enough security when browsing the internet these days.
