Hi there! I’m glad you reached out, I can help clarify that for you.
If you are using Solid Security Basic, then you should continue using the Patchstack plugin. Solid Security Basic does all the WordPress hardening and user account security you need, but Patchstack covers the plugin vulnerabilities. They pair really nicely.
But if you have Solid Security Pro then our unique deep integration with Patchstack really makes the MOST out of that vulnerability information automatically for you. So no need for the additional plugin because you get Patchstack and even more with Solid Security.
If you have more questions about this at all, feel free to reach out to us via our contact form. Thank you!
