Flow control expert: Skynet Firewall.

Skynet Flow Control Firewall.

It's Tianxun Skynet (

The latest product based on the industry's famous Skynet hardware firewall. It is divided into three series: carrier-class, enterprise-class and basic type.

The first gigabit firewall in China.

China's first gigabit firewall successfully developed and tested by the Ministry of Public Security, with high performance and high reliability, after a long period of testing, suitable for a variety of complex network environments and support a variety of network protocols and applications.

A large number of concurrent connections and access control policies.

The optimized SNOS core effectively combines the data exchange capabilities of the dedicated security processing chip (ASIC) with the parallel processing capabilities of the system, and supports ultra-large-scale concurrent connections and access control policies of more than 10,000.

Dual-machine redundancy.

As an egress device for a large network, it is necessary to ensure the high availability of the network and eliminate single points of failure. In addition to the active standby mode, the firewall dual-node hot standby also supports the active active mode, which improves the utilization rate of the firewall and realizes the superposition of firewall performance.

Perfect support for dynamic routing protocols.

For large and complex networks, dynamic routing support is the key to networking. The firewall supports the RIP BGP OSPF dynamic routing protocol, simplifying complex networks.

Operational bandwidth management technology.

The firewall strictly controls the uplink and downlink bandwidth, the number of uplink and downlink packets, and the number of concurrent connections of tens of thousands of IP addresses, so as to realize the operation of large-scale networks. Using the unique dynamic bandwidth adjustment technology of the firewall, the bandwidth of each IP address is automatically adjusted according to the number of concurrent connections and the number of hosts, which is greatly convenient for the network management system.

A virtual firewall to personalize the protection of each network.

In large network environments, where personalized protection is required for each network or server farm, the virtual firewall function assigns a virtual firewall system to each network segment and manages them separately, saving additional firewall investment and reducing management problems.

The price is also the cheapest in China, and it can be said that it is the first in the country in terms of performance and defense.

ZoneAlarm Outpost can outpost the response to Trojans and be more sensitive, but in general, it is still recommended to use ZoneAlarm There is no better firewall than him, and there is no need for ordinary families to install this
