The SRA Platform SRA Clientless Connectivity

The Internet has made it possible for remote workers to travel the world and still have access to the network, from virtually any place on the planet. Your authorized employees, partners or trusted clients can use Dell SonicWALL Secure Remote Access (SRA) Series to securely plug into your network from home, the road, or even from on top of a remote mountain retreat. It doesn't matter, as long as there's Internet access and a Web browser available.

What does "Clientless" mean?

The "clientless" nature of the Dell SonicWALL SSL VPN appliance means that there is no need for the administrator to install a fat client component manually to a computer that will be used for remote access. This removes a tremendous burden, and thereby greatly expands the concept of remote access. It means that since there is no pre-installation or pre-configuration required, an authorized remote worker can sit down at any computer, anywhere in the world, and securely access their corporate resources. In its purest form, SSL VPN/remote access is strictly browser-based. This is true, for example, for proxied Web applications. In other cases, a "thin" client is automatically pushed through the Web browser in the form of tiny Java® applets or ActiveX® controls. These enable access to files (FTP, CIFS), desktops and applications (Citrix®, Windows® Terminal Server, VNC), and terminals (Telnet, SSH). The difference between these thin clients and an IPSec fat client is that the SSL VPN clients are stateless, do not have to be manually installed or configured, and can be delivered transparently through the Web browser to any computer on demand.

Can my computer connect to the SSL VPN appliance?

Virtually any computer with Internet access and a Web browser can connect to the Dell SonicWALL SRA appliance Virtual Office. Your computer must be running Internet Explorer, Chrome, Firefox®, Opera®, or Safari®. In some usage cases, your browser must be configured to enable Java and ActiveX for the connection to take place.

Virtual Desktop Infrastructure.

Many corporations already publish applications via Citrix servers or Microsoft Terminal Servers within the corporate network. Dell SonicWALL SSL VPN extends control of these applications beyond the corporate network to remote users via Citrix and Terminal Server "thin" clients. Dell SonicWALL SRA Series appliances also provide users with Remote Desktop Control capabilities via "thin" clients. These capabilities provide users with access to work stations using the Remote Desktop Protocol RDP)), as well as Virtual Network Computing (VNC) protocols. The RDP and VNC clients are automatically delivered to authorized remote users through their browsers in the form of an ActiveX or Java application. Access is delivered through the network resources feature, which is a set of network objects of a trusted network, which can be accessed through the SSL VPN. These network resources can be pre-defined by the administrator and assigned to users or groups as bookmarks, or users can define and bookmark their own network resources.

Stay in control.

Just because users can connect easily from anywhere in the world, it does not mean that you have to give up control over your environment. Each user has a personalized portal that displays only the resources that each individual user is authorized to access, depending on policy.
