SSTP VPN Features and advantages

SSTP VPN Features and advantages:

SSTP (Secure Socket Tunneling Protocol) is a Microsoft proprietary VPN protocol which works only on Windows based OS, it is considered secured VPN tunnel that provides a way to transport PPP-traffic through an SSL or TLS channel. Which provides transport level security with encryption, key-negotiation, and traffic-integrity checking. SSL or TLS uses TCP port 443 which allows Secure Socket Tunneling Protocol to pass through virtually all firewalls and proxy-servers but except for authenticated web-proxies.
SSTP is generally considered to be one of the most secure protocols for VPN, although it does not have the same open-source benefits as OpenVPN

How SSTP VPN works?

In SSTP a client-device can connects with server using port number 443 after having the internet access. You are required authentication on client side only; client gets server’s certificate for authentication and if it is invalid then the connection gets terminated. Once it is connected, client sends HTTPS-request as well as SSTP control packets, then PPP negotiation and after that PPP assigns IP interfaces to both ends. Now both sides are ready IP communication with each other.

Features and advantages of SSTP

SSTP VPN protocol has following advantages and features that you should consider beforehand to get the best out of it.
  • It uses the SSL port that is port number 443.
  • SSTP almost have the same advantages as OpenVPN and like bypassing NAT firewalls because of ssl port.
  • SSTP uses SSL transmissions instead of IPSec.
  • SSTP uses 2048 bits encryption & authentication-certificates.
  • SSTP can penetrate most of the firewalls.
  •  SSTP is supported by open source VPN server SoftEther.
  • SSTP is considered very secure because of the strong AES encryption.
  • SSTP supports Windows based operating systems like windows 7, 8 or 10.
  • SSTP provides Perfect Forward Secrecy.

On the other hand SSTP is a proprietary technology, SSTP is owned by Microsoft and does not have support for modern mobile and desktop OS.
