Breeze,
I am not sure because I do not use any other security plugin at the moment. But I have no doubt that this plugin will work fine with another security plugin that has other additional features you need for protection. Just make sure you don’t have anything overlapping because HideMyWP has a firewall and so do most security plugins so you don’t want overlapping features active at the same time that could cause conflict. HideMyWP is a great plugin and I highly recommend it as it follows best practices and I have had no issues. Support is excellent as well.
