SonicWall SSL VPN
Virtual Private Network (VPN) for Secure Remote Access

Features and Benefits:

Enhanced layered security is enabled when a SonicWall Network Security Appliance uses powerful deep packet inspection technology to scan VPN traffic for malicious threats such as viruses, worms, Trojans and spyware. The combined solution is known as SonicWall Clean VPN*.

Easy VPN management SonicWall's award-winning Global Management System (GMS) provides simplified management of SonicWall VPN Client connections.

SSL VPN for Network Security:

• NetExtender - Clientless connectivity removes the need for a pre-installed or "fat" VPN client, thus freeing administrators from the tedious and costly task of installing and updating a client on users' Windows, Mac or Linux-based systems.
• NetExtender technology provides enhanced capabilities such as network level access to additional resources, services and applications on the corporate network.
• Mobile device support to access an entire intranet as well as Web-based applications provides greater flexibility for a remote workforce.

Global VPN Client:

• Easy-to-follow wizards help users install and configure a VPN connection quickly and easily. IPSec VPN users simply enter the domain name or IP address of the SonicWall VPN gateway and the Global VPN Client configuration policy is automatically downloaded.
• Extended user reach and productivity by connecting from any single or dualprocessor computer running one of a broad range of Microsoft® Windows® platforms. Further extending secure remote access, the Global VPN Client enables encapsulated VPN traffic to traverse any IP network using Network Address Translation (NAT).
• VPN session reliability provides simultaneous Global VPN Client connections that can be established to multiple SonicWall VPN gateways. The Global VPN Client supports redundant SonicWall VPN gateways to ensure mission-critical network access in the event the primary gateway fails.

*Clean VPN requires an active Gateway Anti-Virus, Anti-Spyware and Intrusion Prevention subscription for the governing SonicWall network security appliance.

Mobile Connect:

Simple, policy-enforced secure access to mission-critical applications and data for iOS, OS X, Android, Chrome OS, Kindle Fire and Windows mobile devices.

Give your employees safe, easy access to the data and resources they need to be productive from a range of devices, including iOS, OS X, Android™, Chrome OS, Kindle Fire and Windows. At the same time, ensure that the corporate network is protected from mobile security threats.

The SonicWall™ Mobile Connect™ application works in combination with SonicWall Secure Mobile Access (SMA) or next-generation firewall appliances. Mobile workers simply install and launch the Mobile Connect application on their iOS, OS X, Android, Chrome OS or Windows mobile device to establish a secure connection to an SMA or next-generation firewall appliance. The encrypted SSL VPN connection will protect traffic from being intercepted and keep in-flight data secure. Contextaware authentication ensures only authorised users and trusted devices are granted access.

Behind the scenes, IT can easily provision and manage access policies via SonicWall appliances through a single management interface, including restricting VPN access to a set of trusted mobile apps allowed by the administrator. Plus, the SonicWall solution integrates easily with most back-end authentication systems, including two-factor authentication, so you can efficiently extend your preferred authentication practices to your mobile workers.

Features and Benefits

Ease of use
iOS, OS X, Windows 10, Android, Chrome OS and Kindle users can easily download and install the Mobile Connect app via the App Store™, Google Play, Chrome Web Store, Amazon App Store, or Windows Store. For Windows 8.1 mobile device users, Mobile Connect is embedded in the Windows 8.1 operating system so there is no need to download and install another VPN client app.

Centralized policy management
IT can provision and manage mobile device access via SonicWall appliances - including control of all web resources, file shares and client-server resources - through a single management interface. Unlike other VPN solutions, the SonicWall solution allows you to quickly set rolebased policy for mobile and laptop devices and users with a single rule across all objects; as a result, policy management can take only minutes instead of hours.

Verification of both user and device
A Mobile Connect user is granted access to the corporate network only after the user has been authenticated and mobile device integrity has been verified. End Point Control can determine whether an iOS device has been jailbroken or an Android device has been rooted, as well as whether a certificate is present or the OS version is current, and then reject or quarantine the connection as appropriate.

Easy access to appropriate resources
iOS, Android, Chrome OS, Kindle and Windows mobile devices can connect to all allowed network resources, including web-based, client/server, server-based, host-based and back-connect applications. Once a user and device are verified, Mobile Connect offers pre-configured bookmarks for one-click access to corporate applications and resources for which the user and device has privileges.

Malware protection
When deployed with a SonicWall nextgeneration firewall, Mobile Connect establishes a Clean VPN™, an extra layer of protection that decrypts and scans all SSL VPN traffic for malware before it enters the network.

Mobile device registration and authorization policy management
With Mobile Connect and Secure Mobile Access OS (versions 11.0 and above) for Secure Mobile Access 1000 Series appliances, prior to granting network access, if a mobile device has not previously registered with the SMA appliance, the user is presented with a device authorization policy for acceptance. The user must accept the terms of the policy to register the device and gain access to allowed corporate resources and data. The terms of the policy are customizable by the administrator.

Per-application VPN
Mobile Connect in combination with Secure Mobile Access OS (versions 11.0 and above) for Secure Mobile Access 1000 Series appliances, enables administrators to establish and enforce policies to designate which apps on a mobile device can be granted VPN access to the network. This ensures that only authorised mobile business apps utilize VPN access. Mobile Connect is the only solution that requires no modification of mobile apps for per app VPN access. Any mobile app or secure container can be supported with no modifications, app wrapping or SDK development.

One-click Secure Intranet File Browse and On-Device Data Protection
Protect company data at rest on mobile devices. Authenticated users can securely browse and view allowed intranet file shares and files from within the Mobile Connect app. Administrators can establish and enforce mobile application management policy for the Mobile Connect app to control whether files viewed can be opened in other apps, copied to the clipboard, printed or cached securely within the Mobile Connect app. For iOS devices, this allows administrators to isolate business data from personal data stored on the device and reduces the risk of data loss. In addition, if the user’s credentials are revoked, content stored in the Mobile Connect app is locked and can no longer be accessed or viewed.

Auto-launch VPN
URL control allows apps that require a VPN connection for business (including Safari) to create a VPN profile and automatically initiate or disconnect Mobile Connect on launch (requires compatible server firmware). In addition, for iOS or OS X devices, to simplify use when a secure connection is required, VPN on Demand automatically initiates a secure SSL VPN session when a user requests internal data, applications, websites or hosts.

Integration with existing authentication solutions
The SonicWall solution supports easy integration with most back-end authentication systems, such as LDAP, Active Directory and Radius, so you can efficiently extend your preferred authentication practices to your mobile workers. For increased security, you can enable one-time password generation and easily integrate with two-factor authentication technologies.

Application intelligence and control
When deployed with a next-generation firewall, IT can easily define and enforce how application and bandwidth assets are used.

Abstract

While pre-configured or “fat” client is preferential for most network users, many IT organizations are making the switch to a thin client or SSL VPN model in order to reduce costs and better protect their network from security risks. Unlike a fat clients or IPSec VPN, thin client enables remote users to access the network from any computer equipped with an Internet connection and standard web browser.

No longer are remote users limited to using speciallyconfigured laptops provided by the IT department, as is the case with more traditional VPN models. IPSec VPN may be especially useful in areas where the IT administrator tightly controls and manages only a small number of remote workstations, while with fat client VPN systems administrators can allow users to have a greater level of access. However, users now can have the best of both worlds with SonicWall™ Secure Remote Access (SRA) NetExtender thin client technology. The tech brief below explains how.

Introduction

With SonicWall NetExtender, users enjoy seamless and secure network layer access to the intranet, file, desktop and terminal resources, including Microsoft® Outlook® and Microsoft SharePoint. Pushed transparently onto the client’s desktop, laptop or smartphone, the thin client enhances users’ capabilities and significantly reduces the IT administrative costs and time required to maintain and manage remote access.

SonicWall NetExtender

Simplified and secure end user access for anywhere, NetExtender adds more power to the SonicWall SRA 4600 and 1600, adding capabilities such as seamless and secure access to any resource on the corporate network including servers or custom applications. Unlike a fat client, NetExtender extends thin client transparently to the client’s desktop or laptop, and installs it automatically to facilitate this broader level of access. It assigns remote users an IP address from a preset pool of IP addresses, enabling them to access any TCP/IP-based resource on the corporate network including a wide variety of legacy applications and services. Remote users gain Layer-3 level access to the protected internal network.

The user experience is similar to that of a traditional IPSec VPN client, except that manual client installation is not required. Additionally, users do not have to worry about Network Address Translation (NAT) devices and proxies, which are the bane of traditional IPSec-based VPNs.

NetExtender creates a virtual adapter for secure point-to-point access to any allowed host or subnet on the internal network. Unlike the stateless nature of the traditional SSL VPN, NetExtender stays resident on the client machine even after the connection is closed.

The advantage of running NetExtender as a resident application on the remote system is that it speeds up login times in subsequent uses. Of course, if a remote user chooses to deploy the standalone NetExtender client on their remote machine, but later logs in from a separate machine, he or she can still gain access with no problems at all.

Users can access NetExtender easily in the traditional way from any machine using the browser portal. They can also select the Uninstall on browser exit option to have NetExtender remove itself after the session ends.

Extend network access through native clients

With NetExtender technology, remote users will gain: Access to email through native clients residing on the user’s laptop, including everything from Microsoft Outlook and Lotus Notes Access to commercial or property applications and flexible network access.

Enforce granular access control policies

By deploying the SonicWall NetExtender, along with Enforced Client Anti-Virus and Anti-Spyware, on the remote workstations, administrators can enforce a policy that requires every remote workstation that accesses the network to have current versions of anti-virus and anti-spyware software up and running.

Multiple NetExtender IP range and route support, permits the administrator to impose granular access control policies by assigning specific IP addresses or ranges of IP addresses, and specific routes to individual users or groups. This feature also helps to provide control that is more granular over who can access which network resources through NetExtender.

Enhance firewall encryption and security

SonicWall Secure Remote Access (SRA) provides a high level of security on its own. Besides the encryption that is inherent to the SSL model, the personalized SonicWall web portal enforces a high level of granularity for each user that the administrator controls. The SRA Series appliance grants remote users access only to authorised areas through the portal. NetExtender also provides enhanced security benefits. With NetExtender, you can force all client traffic through the SSL VPN tunnel, and apply all security services that are running on your primary SonicWall Network Security Appliance (NSA) or SonicWall TZ Series firewall - including enforcement of the SonicWall hostbased, anti-virus solution.

Versatile, bidirectional support for remote PCs

While the application proxies support specific protocols such as FTP, HTTP, RDP or VNC, NetExtender is not protocol specific. Rather, it can support any TCP/IP-based application that is running on the local client. Besides extended access, this also means that communications are bidirectional. In other words, the remote client can initiate communications with a host on the internal network, and the reverse is also true - hosts on the internal network can also initiate communications with the remote PC. This functionality is particularly useful for management and administration of remote PCs.

Flexible support for multiple platforms

Available as a standalone application for all SRA Series appliances, the NetExtender client can be launched through the Virtual Office web portal, or as a native application on Windows, Mac OS and Linux PCs and laptops, to access any authorised resource on the corporate network.

NetExtender utilizes a standard interface across all SSL VPN clients, creating a unified look and feel. Support for multiple platforms provides users with greater flexibility to access remote resources from various endpoints. Initial distribution of NetExtender is either through the Virtual Office portal or via a standalone installer. After initial distribution, users can launch NetExtender independently as a standard application. The NetExtender client supports domain login scripts, and implements a custom dialer that allows launch from the Windows Network Connections menu.

For mobile devices and operating systems, SonicWall Mobile Connect™, a single unified client app for Apple iOS, OS X, Google Android™, Kindle Fire and Windows 8.1 or newer, provides smartphone, tablet, laptop and desktop users network-level access to corporate and academic resources over encrypted SSL VPN connections.
