Legacy firewall devices have their limitations on networking protection and are often dedicated. The vulnerabilities of contemporary networks ranging from Web surfing, e-mail, FTP, to various instant messaging and P2P softwares, present a heavy burden for network administrators.
 

Conventional firewalls are blind to today's attacks, and also cannot detect inappropriate e-mail and Web content. The most common solution is complex, costly collection of independent systems to deal with each of these threats along with network-level intrusions and attacks.

The VigorPro 5500 employs a unique, hardware-accelerated architecture the provides the ability to perform real-time security without slowing critical network applications, such as Web traffic. Software-based anti-virus systems, which are designed for scanning non-real-time email messages, are too slow to be used to scan Web traffic or other real-time network applications.
 

Conventional way to protection against virus or malicious program, it required each host to install software on the host. To install software on a large number of hosts is a time consuming process. To evaluate for vulnerabilities, both scan engine and virus database needs constant upgrade. It is very costly and annoying for IT personnel with high maintenance. While VigorPro 5500 works as firewall as well as internet gateway, so by nature VigorPro 5500 blocks any attacks at the point of network entry. Through the user interface, the security administrator can monitor and instruct the VigorPro 5500 to look for any vulnerability in network-level. Provide protection of all hosts inside network edge before threats intrude.

Conventional firewalls only inspect packets connection behavior to against any connection-based attack. While the content-based threats today. such as virus, worms, Trojans or banned content, which spread faster and do more damage. Conventional firewalls bypass the widely spread content-based threat and expose internal network to outside world. VigorPro 5500 deploys DrayTek's unique MSSI™ (Multi-stack Stateful Inspection) mechanism. With MSSI™ , VigorPro 5500 inspects packet streams, compares any suspected content or behavior with build-in database in real-time, and provide inline anti-virus and anti-intrusion protection.
