SonicWALL has expanded its SSL VPN product line with the launch of SSL VPN 4.0 firmware with new features to small- to mid-sized businesses (SMBs), including web application firewall, virtual assist and simplified unified policy.

The company said that the new offering is designed to enable controlled network access for a distributed workforce and the web application firewall detects and protects web applications, including the SSL VPN appliance itself from the latest web-based attacks.

According to SonicWALL, the SSL VPN 4.0 firmware upgrade is available for the SSL VPN 2000, SSL VPN 4000 and Secure Remote Access (SRA) 4200 appliances. The web application firewall is a new subscription-based service that employs an updated signature database to protect against modern, web-based threats.

The company said that Virtual Assist allows users to access their personal computers located outside the LAN of the SRA appliance. By installing the application on a Windows PC with internet access, that computer becomes available for users access to view the desktop and have mouse/keyboard control.

The Windows NetExtender client has been redesigned with a new look with the underlying technology implementing a custom-dialer that allows it to be launched from the Windows ‘Network Connections’ menu.

SonicWALL SSL VPN devices support Simple Network Management Protocol (SNMP) which will report remote access statistics and all granular bookmarks and policies are now displayed on a single page, providing for a single place to manage all SSL VPN policies.

Matthew Dieckman, product line manager at SonicWALL, said: Over the past four years SonicWALL has provided industry-leading SSL VPN remote access solutions to organisations of all sizes, allowing SMBs to enjoy the same features and capabilities as larger enterprises.

SonicWALL’s new SSL VPN 4.0 is a milestone release that captures the benefits of our latest SSL VPN platforms and sets the stage for innovation in secure remote access for years to come. Our SSL VPN technology now provides SMBs with optimal control, flexibility and functionality at a price point that doesn’t compromise their budgets.
