WordFence and Sucuri

Does anyone have any experience with both of these solutions being in place at the same time? I am getting redirect errors and cannot connect to wp-login.php. I was told that WordFence was a firewall for the server and that Sucuri is a firewall for the web (essentially an extra layer). Not sure if anyone has any insight. I hate to ditch one of the solutions but they are preventing me from getting work done and that’s a no-no.
