Part 1: What is Kerio Control?

Before we dissect the offline licensing mechanism, it is crucial to understand the host application. Kerio Control (now developed and supported by GFI Software) is a next-generation firewall (NGFW) and Unified Threat Management (UTM) solution. It is renowned for bridging the gap between enterprise-grade security and small-to-medium business (SMB) affordability.

Kerio Control offers:

• Stateful Packet Inspection (SPI)
• Intrusion Prevention System (IPS)
• Gateway Antivirus (AV)
• VPN (IPsec, OpenVPN, and L2TP)
• Web Content Filtering
