Reduces unexpected reboots and fixes memory leaks.
Administrators can define rules based on traffic types, specific users, or time intervals to ensure resource equity:
| Scenario | Throughput | CPU Load | | :--- | :--- | :--- | | No filtering (pure NAT) | 945 Mbps | 12% | | Firewall rules + basic logging | 940 Mbps | 15% | | Firewall + Web filter (no HTTPS inspection) | 900 Mbps | 28% | | Firewall + Web filter + HTTPS inspect | 720 Mbps | 55% | | Full UTM (IPS + AV + Web filter) | 520 Mbps | 78% |
Guarantees minimum bandwidth and low latency for mission-critical services like VoIP, video conferencing, and ERP database connections.
Continually monitors link health. If a primary internet connection drops, traffic is instantly routed through a backup link (e.g., a secondary ISP or a 4G/5G modem) to maintain business continuity. Flexible Deployment Options kerio control 9.4.2
Updated underlying drivers ensure smoother operation on newer network interface cards (NICs) and modern server chipsets. Conclusion

The release also enhanced functionality, allowing remote users to access internal web resources (like intranet portals or NAS management interfaces) through a browser without installing a full VPN client. From an administrative perspective, 9.4.2 introduced more granular controls for the VPN Dashboard , enabling live monitoring of tunnel status, data usage, and connected client operating system versions. This transparency allows an IT manager to quickly detect unauthorized devices or anomalous traffic patterns, such as a single user establishing multiple simultaneous VPN connections.
