Manages both inbound and outbound traffic with granular policies based on URL, application, content category, and time of day.
Standardized protocol support allows secure site-to-site tunnels between Kerio Control and third-party routers or cloud environments.
The root cause was identified as , a network optimization technique that, in some configurations, conflicted with Kerio Control's packet processing engine. GRO is designed to improve network performance by aggregating smaller packets into larger ones, reducing CPU overhead. However, on certain hardware (NG1xx, NG3xx, NG5xx series) and hypervisors, this optimization introduced severe instability.
