Patchstack instead of Wordfence?

Hi, is Patchstack meant to be an additional security plugin or meant to replace other security plugins like Wordfence? I ask as I am a bit confused on what Patchstack actually does compared to the other plugins. The reason is because I saw on SolidWP (formerly known as Ithemes) website that Patchstack is included in their paid versions. That tells me Patchstack is an add-on to harden already existing secutity features provided by SolidWP. Now, SolidWP is a Wordfence competitor, can I then assume to also use Wordfence and Patchstack together? Or is Patchstack working with SolidWP exclusively because they “fulfil” each other better? (maybe because the latter 2 come from same company/developer?) Thanks 🙂
