Defender Plugin with iThemes Security Pro

Hi

A general question for you.

In issue 534 of the Whip you have a link to an article that promotes the iThemes Security Pro plugin. I am an iThemes member and so have access to this plugin.

My question is "can I use the Defender plugin and the iThemes plugin both on the same site? The plugins cross over in terms of what they do and so I wonder if it has been tested at all?"

Thanks

Allan
