A highly scalable application network appliance is described herein. According to one embodiment, a network element includes a switch fabric, a first service module coupled to the switch fabric, and a second service module coupled to the first service module over the switch fabric. In response to packets of a network transaction received from a client over a first network to access a server of a data center having multiple servers over a second network, the first service module is configured to perform a first portion of OSI (open system interconnection) compatible layers of network processes on the packets while the second service module is configured to perform a second portion of the OSI compatible layers of network processes on the packets. The first portion includes at least one OSI compatible layer that is not included in the second portion. Other methods and apparatuses are also described.

An integrated, multi-service network client for cellular mobile devices is described. The multi-service network client can be deployed as a single software package on cellular mobile network devices to provide integrated services including secure enterprise virtual private network (VPN) connectivity, acceleration, security management including monitored and enforced endpoint compliance, and collaboration services. Once installed on the cellular mobile device, the multi-service client integrates with an operating system of the device to provide a single entry point for user authentication for secure enterprise connectivity, endpoint security services including endpoint compliance with respect to anti-virus and spyware software, and comprehensive integrity checks. That is, the multi-service client provides a common user interface to the integrated services, and provides a VPN handler that interfaces with the operating system to provide an entry point for network traffic to which the integrated services can be seamlessly applied.

Multi-service VPN network client for mobile device

Disclosed herein are systems and methods that allow for secure access to websites and web-based applications and other resources available through the browser. Also described are systems and methods for secure use and retention of user credentials, as well as methods for dynamic authentication of users and integrity checking of service providers in online environments. Thus, described in the present specification are systems and methods for constructing and destroying private, secure, browsing environments (a secure disposable browser), insulating the user from the threats associated with being online for the purposes of providing secure, policy-based interaction with online services.

Disposable browsers and authentication techniques for a secure online user environment

An integrated, multi-service network client for cellular mobile devices is described. The multi-service client includes a VPN handler having an interface programmed to exchange the network packets with the security manager for application of the security service, wherein the VPN handler is configurable to operate in one of an enterprise mode and in a non-enterprise mode, wherein in the enterprise mode the VPN handler establishes a VPN connection with a remote VPN security device and provides encryption services to securely tunnel the network packets between the cellular mobile device and the remote VPN security device, and wherein in the non-enterprise mode the VPN handler directs the network packets to the security manager without application of the encryption services and communicates the network packets to a packet-based network without tunneling the packets.

Dual-Mode Multi-Service VPN Network Client for Mobile Device

An integrated, multi-service virtual private network (VPN) network client for cellular mobile devices is described. The multi-service network client can be deployed as a single software package on cellular mobile network devices to provide integrated services including secure enterprise VPN connectivity, acceleration, security management including monitored and enforced endpoint compliance, and collaboration services. The multi-service client integrates with an operating system of the device to provide a VPN handler to establish a VPN connection with a remote VPN security device. The VPN network client includes to data acceleration module exchange network packets with the VPN handler and apply at least one acceleration service to the network packets, and a VPN control application that provides a unified user interface that allows a user to configure both the VPN handler and the data acceleration module.

A security gateway, for use in a network system for linking at least a client end and a server end, includes a user interface, a SSL VPN driver, a connection interface and an IPSEC VPN driver. The security gateway supports IPSEC and SSL protocols. Before establishing an IPSEC VPN between a client end and a server end, the security gateway will perform ID authentication for the user of the client end with a widely-used SSL protocol, so as to establish a SSL VPN between a server end and a client end. When the ID of the client end is authorized, a configuration file comprising the SA is generated and then safely sent to the client end through the SSL VPN tunnel. After the client end receives and executes the configuration file having the SA, an IPSEC VPN tunnel between the server end and the client end is established.

Security gateway utilizing ssl protocol protection and related method

The present invention discloses a security gateway with SSL protection and method for the same, which are suitable for connecting a network system having a client end and a server end. The security gateway includes an operation interface, a SSL VPN driving unit, a connection interface and an IPSEC VPN driving unit, such that the security gateway can support both SSL and IPSEC security protocols. When any client end intends to establish IPSEC VPN with the server end, a network browser having the SSL security protocol is supported by most client ends; the security gateway will first perform an ID authentication associated with the SSL security protocol to establish a SSL VPN tunnel between the server end and the client end; after the security gateway confirms the situation that the ID authentication of the client end is legal, its security association in form of a configuration file is automatically and securely transmitted to the client end under the protection of the SSL VPN tunnel; after user at the client end executes the configuration file, an IPSEC VPN tunnel can be established between the server end and the client end.
