Q&A

• How does a split tunnel improve efficiency and security?

  Using a split tunnel allows remote users to have separate paths for corporate network and third-party traffic, improving efficiency and security by allowing the VPN concentrator to handle corporate traffic while directing non-corporate traffic directly without the VPN tunnel.

• What is a split tunnel in a VPN?

  A split tunnel in a VPN allows certain traffic to be directed through the encrypted VPN connection while other non-corporate traffic is sent outside the VPN. It enables users to access both corporate and external resources efficiently.

• What is a full VPN tunnel?

  A full VPN tunnel ensures that all traffic is encrypted and sent through the VPN connection, providing comprehensive security for data transmitted between the client and the VPN concentrator.

• What is the web cryptography API?

  The web cryptography API enables the operation of a VPN client within a web browser, eliminating the requirement for separate client software installation. It requires an HTML5-compliant browser for functionality.

• What are clientless VPNs?

  Clientless VPNs, using HTML 5, enable connectivity without specific VPN clients, allowing users to establish secure connections through web browsers without the need for additional software installation.

• What is a site-to-site VPN?

  Site-to-site VPNs allow encrypted communication between different locations, often integrated into existing firewalls. They are commonly used for always-on connections to ensure secure data exchange between the sites.

• How does VPN encryption work?

  VPN software can be manually enabled or configured for an always-on connection, providing encrypted communication between the client workstation and the central site. Encryption and decryption processes occur at both ends to ensure secure data transmission.

• What is client to site VPN?

  Client to site VPN is a configuration that requires software installation on the client workstation to enable secure communication with a central site over a VPN connection.

• Can a VPN be installed on different operating systems?

  Yes, VPN clients are available for various operating systems, allowing users to install and use VPN services on their preferred devices.

• What is a VPN concentrator?

  A VPN concentrator is a device that encrypts and decrypts information for secure communication. It is commonly used to manage and facilitate VPN connections.

• What does a VPN do?

  A VPN encrypts data for secure transmission over public networks, ensuring that the information remains confidential and protected from unauthorized access.

• 00:02 A VPN encrypts data for secure transmission over public networks. It can be used with a VPN concentrator and can be installed on various operating systems.
• 01:07 VPNs allow secure communication between client workstations and a central site. VPN software can be manually enabled or configured as an always-on connection, providing encrypted communication. Encryption and decryption happen at the client and concentrator ends, ensuring secure data transmission.
• 02:10 Site-to-site VPNs allow encrypted communication between different locations, often built into existing firewalls. Clientless VPNs, using HTML 5, enable connectivity without specific VPN clients.
• 03:21 The web cryptography API allows running a VPN client inside the browser, eliminating the need for additional software. Full VPN tunnel means all traffic is encrypted and sent through the VPN connection.
• 04:27 Your VPN may configure a split tunnel, where some traffic is sent over the encrypted VPN while other non-corporate traffic is sent outside of the VPN connection.
• 05:30 Using a split tunnel allows remote users to have separate paths for corporate network and third-party traffic, improving efficiency and security.
