Kerio Control 9.3.0 Build 3273 (Firewall)

Kerio Control (Kerio WinRoute Firewall) is an award-winning UTM firewall designed to protect businesses from a comprehensive range of invasive and crippling corporate network threats.

Kerio Control’s auto-updating security layer detects and prevents emerging threats automatically while providing network administrators with flexible user policy tools. The software also provides the complete bandwidth management and QoS control, detailed network monitoring, and IPsec VPN connectivity for desktops, mobile devices and multiple sites.

Designed for corporate networks, it defends against external attacks and viruses and can restrict access to websites based on their content.

Kerio Control provides superior network protection and intelligence that is stable, secure, and above all, simple to manage. That sets new standards in versatility, security and user access control.

Kerio Control is equipped with VPN server, optional embedded Sophos Anti-Virus, integrated customizable ISS Orange Web Filter, and user-specific Internet access management. Also provides a multi-layer architecture for protecting networks, servers and users.

Kerio has added a new IDS/IPS system. It plays an instrumental role in detecting and preventing application exploits and malicious traffic. Just like built-in Sophos gateway antivirus, the IDS/IPS gets frequent automatic updates to ensure that networks are continuously shielded from emerging threats.
