Secure connectivity
Given the prevalence and importance of information technology (IT) systems today and the nature and scale of both the opportunities and risks associated with significant deployments of new networking technologies, organizations are forced to evaluate solutions to build up a safer infrastructure to secure online transactions, in which involve exchange of valuable information. The infrastructure should be tailored to meet operation requirements for expanding remote sites as well as mobile teleworkers.

Proactive protection
Malicious virus, worm, exploits could cripple corporate networks and halt business transactions. In addition to severe financial loss, you also risk leakage of confidential information.
As mass-mailing software companies mushroom on the Internet, your network is bombarded with massive amounts of junk mails (spam). Without intelligent detection and proactive blocking, users have to go through the tedious and time-consuming task of sieving through the overflowing mailbox, and such scenario leads to serious productivity loss.

Policy compliance
With numerous file-sharing (P2P) and Instant Messaging (IM) applications, it is easier for company employees to share files and chat online during work hours. Rapid file sharing not only compromises network safety with the sharing of questionable files containing malicious viruses, but may also violate copyright issues and create legal hassles.

Network resilience
ISP links broken, hardware and software failure on the gateway, dead VPN tunnels—these are severe challenges IT staff face when designing the network infrastructure. In short, we need to take fault tolerance on the network path into consideration when build up a highly available network infrastructure for non-stop operations.

With Vantage CNM (Centralized Network Management), users can achieve the follow objects:
- Easy VPN management and diagnostic capability
