• How It Works: Based on HTTP protocol, allowing simultaneous access to different pages or services.
• Use Case: Ideal for opening multiple web pages or accessing concurrent services at the same time.

VPN:

• Purpose: Connects to a public network while maintaining privacy and security.
• How It Works: Uses tunneling techniques like SNI or WPA3 to protect data.
• Use Case: Best for connecting to specific applications or services while keeping your privacy and data secure.
• Considerations: Requires more complex setup and software, offering encryption and anonymity.

Summary:

• SS is for concurrent access to multiple services or pages.
• VPN is for secure, private internet connections.
• Choose SS when accessing multiple services or pages simultaneously.
