AT&T Premises-based VPN

AT&T Premises-Based VPN allows businesses to build upon current investments by providing dedicated, broadband, and remote access solutions for connection to the AT&T global network or the Internet. These Premises-Based VPNs are delivered by adding intelligent devices such as firewalls or VPN tunneling terminating at your business's edge and a connection is established by programming appropriate levels of network security, user access control, and bandwidth prioritization.

AT&T Premises-Based VPN utilizes Internet Security Protocol (IPSec) or Secure Sockets Layer (SSL) to prevent data tampering and help ensure the confidentiality, integrity, and authenticity of your data communications.

IPSec is a set of security protocols that determines data security at the network layer for IP networks, including methods for network authentication, data encryption, and integrity checking. This comprehensive tunneling standard for VPNs protects data end-to-end, from the remote user or desktop to the LAN (terminating branch).

SSL, an application layer encryption protocol, allows secure access to and from user devices located outside of traditional enterprise boundaries. Ideal for clientless access to web-enabled applications, as well as access to client-server applications, and provides a simplified, efficient way for you to roll out an IP VPN for remote access applications. For remote access environments, SSL secures two applications communicating with each other, while IPSec secures an entire network or secures one network to another.

• Dial access is available using the AT&T dedicated global infrastructure, supporting PSTN (analogue), GSM and ISDN, with the option to bundle up to 4 lines/channels for improved access speed
• AT&T Remote Access Services for wireless offers direct wireless connection to your VPN via designated operator network
• Wireless (WiFi) hotspots cover typical traveling user locations such as hotels, airports, or convention centers. AT&T supports over 6000 hotspots.
• Broadband, dial and wireless single user configurations use the AT&T Global Network Client to handle the security (tunneling & encryption). This client includes a personal firewall to protect the workstation.
• IPSec and firewall implementation is at the lowest possible level to prevent any application by-passing the security features.
