In recent years, there has been an increased dependence on mobile workers. This has prompted a need for providing secure remote access to network resources as well as remote PC control. SonicWall® provides a solution that meets the needs of organizations with demanding remote workforce requirements. SonicWall Secure Remote Access (SRA) Series solutions, flexibly deployable as a hardware or a virtual appliance, are simple to implement and even easier to use for a fraction of the price of most other products.

Remote access has never been so simple to deploy and use. Mobile employees only require a standard browser to log into a customizable portal that provides access to email, files, Web applications and internal Web sites. For even more powerful capabilities such as secure access to any resource on the corporate network including servers and local applications, the appliances transparently push a downloadable thin client (NetExtender) to the user's desktop or laptop.

SonicWall Virtual Assist/Virtual Access can be easily configured and licensed via the administrative interface as a cost-effective alternative to either traditional remote support tools or remote PC access productivity tools. Browser-based Virtual Assist thin clients can be pushed to technicians and customers to establish an interactive support session using SonicWall SRA. Alternatively, Virtual Access can increase productivity by enabling IT administrators or authorised end users to gain secure remote access to their unattended Windows-based computers from anywhere via SonicWall SRA.

Deployment with a SonicWall Network Security appliance running Gateway Anti-Virus, Anti-Spyware and Intrusion Prevention Service along with Application Intelligence and Control further enhances security benefits. Deploying NetExtender in conjunction with Enforced Client Anti-Virus and Anti-Spyware on managed PCs enforces endpoint security. Virtual Assist also offers seamless integration by leveraging the appliance’s local and external authentication facilities. Furthermore, Web Application Firewall Service blocks attacks on the SSL VPN appliance and other Web applications.

SonicWall SRA Series Deployment - Remote Access Solution

  1. Incoming HTTPS traffic is seamlessly forwarded by the SonicWall NSA or TZ Series firewall network security appliance to the SonicWall SRA appliance, which decrypts and authenticates network traffic.
  2. Users are authenticated using the onboard database or through third-party authentication methods such as RSA, VASCO, RADIUS, LDAP, Microsoft Active Directory or Windows NT Domain.
  3. A personalized Web portal provides access to only those resources that the user is authorised to view based on company policies.
  4. To create a Clean VPN environment, traffic is passed through to the NSA or TZ Series firewall (running Gateway Anti-Virus, Anti-Spyware and Intrusion Prevention Services where it is fully inspected for viruses, worms, Trojans, spyware and other sophisticated threats.

Remote Support Solution:

SonicWall Remote Support Solution

With more employees working remotely and customers dispersed globally, it is becoming increasingly important for organizations to provide remote support for off-site business devices such as laptops or home PCs. Ineffective support using expensive and cumbersome tools can undermine IT service level agreements and inhibit remote worker productivity. Using a SonicWall Virtual Assist on an SSL-VPN 4000 or SRA 4200 appliance, a Technician can instantly access a remote device over the Web, transfer files, and chat with the end user, enabling rapid diagnosis and problem resolution, without the need for pre-installed “fat” client.

Web Application Firewall and PCI Compliance

Available as a licensed service, SonicWall's Web Application Firewall (WAF) Service allows customers to protect their Web applications against Web-based attacks. WAF provides automatic signature updates for continuous malware protection and intrusion prevention. It can be used in conjunction with strong two-factor authentication which SSL VPN technology provides to control Web site access. By protecting against common protocol and Web-based vulnerabilities, WAF can significantly help financial, healthcare, e-commerce, e-billing and other related businesses attain PCI compliance. It also provides acceleration features such as content caching which can significantly improve the performance of protected Web sites.

Clean VPN Remote Access Solution:

SonicWall Clean Wireless Solution

More corporations, universities, hospitals and governmental organizations are implementing wireless networks and using SSL VPN as a secure and centralized access control solution. SonicWall SSL VPNs integrate seamlessly with SonicWall wireless access solutions. When deployed alongside a SonicWall firewall (running Gateway Anti-Virus, Anti-Spyware and Intrusion Prevention Services and several SonicPoints, a SonicWall SSL VPN solution ensures that users get access from anywhere on campus and the wireless connections are encrypted via the SSL protocol. As an added bonus, remote workers away from campus can connect into the corporate network via an SSL VPN connection. IT maintains centralized, granular access control over who can access what resources using a single gateway.
