What isSecure Socket Tunneling Protocol (SSTP)

TLS is utilized in SSTP, a VPN protocol, to encrypt traffic and bypass network firewalls. VPNs provide secure connectivity to a host network via open networks like the internet, and tunneling protocols like SSTP are commonly used. SSTP was developed from earlier iterations like L2TP to offer stronger encryption and connectivity. For more information on VPNs and the top 18 vendors, refer to our Guide to Virtual Private Networks (VPN).

FAQs About Transport Layer Security (TLS) and SSTP VPN Protocol

What is the Transport Layer Security (TLS)?

The Transport Layer Security (TLS) is a widely used cryptographic protocol that provides secure communications over networks like the internet. It is commonly used to secure web-based transactions, email transfers, virtual private networks (VPNs), and other data transmissions. TLS is a successor to the Secure Sockets Layer (SSL) protocol and has several versions, with the latest one being TLS 1.3.

What is the Secure Socket Tunneling Protocol (SSTP) VPN?

The Secure Socket Tunneling Protocol (SSTP) VPN is a tunneling protocol that is used to establish a secure connection between two computers over the internet. SSTP was developed by Microsoft and is available for Windows operating systems. It uses the TLS protocol to encrypt traffic and get through common network firewalls. SSTP is a reliable VPN protocol that provides strong encryption and connectivity.

How does SSTP VPN Protocol work?

The SSTP VPN protocol works by encapsulating the data packets transmitted between two computers and encrypting them using the TLS protocol. The encrypted packets are then sent through the internet to their destination. The SSTP protocol uses port 443, which is a commonly open port for web traffic, making it difficult for firewalls to detect and block VPN traffic. SSTP VPN protocol also provides support for Public Key Infrastructure (PKI) authentication, which enables secure user authentication.

What are the benefits of using SSTP VPN Protocol?

The SSTP VPN protocol offers several benefits, including:

  • Strong encryption: SSTP VPN protocol uses the TLS protocol to encrypt traffic, providing strong security for data transmissions.
  • Easy to set up: SSTP VPN protocol is built into Windows operating systems, making it easy to set up and use for Windows users.
  • Reliable: SSTP VPN protocol provides reliable connectivity, even over variable network conditions like Wi-Fi networks.
  • Firewall-friendly: SSTP VPN protocol uses port 443, which is commonly open for web traffic, making it difficult for firewalls to detect and block VPN traffic.

Overall

The Transport Layer Security (TLS) is a widely used cryptographic protocol that provides secure communications over networks like the internet. SSTP VPN protocol uses the TLS protocol to encrypt traffic and enable secure connectivity. It is a reliable and easy-to-set-up VPN protocol that offers strong security for data transmissions. VPNs like SSTP are essential for individuals and businesses alike to secure their online activities and protect their sensitive information from malicious actors on the internet.
