Kemp Virtual GEO LoadMaster is a virtualized appliance that provides multi-site resilience with seamless failover and failback in the event of a critical resource failure as well as offering optimised redirection of traffic to the closest physical service location. In the event of a service disruption, traffic is automatically redirected based on predefined policies to minimize impact and the need for manual intervention. IP Reputation rules subscription and the ability to scale near linearly with allocated memory allows GEO LoadMaster to help protect your applications from DDoS attacks and ensure optimal user experience.
