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.

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.

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.

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

• Complete security policies and UTM management

• Low TCO of massive deployment and device maintenance
