We have a small number of internal web servers that we host on-premises in our data center, along with other services that need to be accessible from the public internet. These include Remote Desktop servers, an SFTP server, Exchange, etc.
All of these servers need extra protection on top of our standard firewall, intrusion detection, and endpoint protection.
The primary use case of Kemp is the reverse proxy for added protection, and load balancing for better performance. We are able to leverage Kemp to protect our web servers by adding content rules and restrictions.
We will continue to add more resources as needed behind Kemp.
