Three RISC Structure of the processor:
Three lays of the nets are adopts the Embedded RISC processor, sets up the foundation that real physics isolates, form the three storeys safe system too.

independent operating system for the layers of three nets:
The embedded operating system of internal and external network are operation independence , has keep the systems independence, have perfect safe protection system.

Resist attack the kernel to design:
To prevent example for SYN Flooding , denial of service attack , source route attacked , half a switch type of scans attacks etc. have guaranteed effectively physics isolates the security of the network floodgate oneself.

Pair of ASIC physics isolates gate:
ASIC physics isolates gate of the independent property, sets up the ferry mechanism of information, can dispose to exchange in real time , such modes as one-way connection , the interrupt switch ,etc.

The six of 100M Ethernet:
It put information to be mutual and in and out for highest bandwidth, smooth of ethernet, the redundancy of the interface,satisfy the broadband access customer.

Intranet user Freedom maill:
Under the situation that realy physics isolates, realize mail receive and dispatch function ,Can verify mail users' true identity; Check , verify and control to the address from the mail ; POP3 way and WEB way collect Extranet's mail safely; SMTP way and WEB way send Extranet's mail safely.

Intranet user Freedom look around www:
Under the situation that realy physics isolates, realize the function of the browse webpages,can prove WEB browses of the users' true identity,Browse Extranet WEB safely.

Intranet user Freedom are Use FTP:
Under the situation that realy physics isolates, realize FTP is connected , under valid authentication, make connection FTP server of the intranet user.

System management and monitoring of invading:

The safe mechanism of management, manage users, browse of around controlling, the function of controlling etc., webpage browsed and relevant information of different data transmission that the record receives and dispatches, the real Times document is kept; One grade of safe protection kernel invades the mechanism of monitoring in real time.

2U framework type of height:
Install the case body for 2U framework type of 94mm , allocate the attachment rail , is suitable for according with 19 inches of wide cabinets of EIA-310-D industrywide standard in height; Very suitable for installing it in the environment in the network computer lab of the high integrated level.

Ferry mechanism of high safe information:
We adopt the latest information ferry mechanism in the world, control strictly the data passing in and out, integrate safe operating system , is it monitor kernel , identity authentication , visit control and person who audit many kinds of safe practices safely to invade, check and filter to type , content of transmitting data ,etc.

Step the platform to support:
Intranet can be Unix, Linux, Mac and Windows 95 / NT/XP/2000/98, various kinds of data types in database system; The security is mutual that it is got that between Intranet and Extranet.

Customize function:

We can follow user's environment , order and make the type of appointing with one degree of bodies for users, the designated agreement is supported, appoint the pattern of exchanging of the data.
