security plugin conflict?

It seems like the both do pretty much the same thing which is scan for vulnerabilities.

I’m not familiar enough with either to give a recommendation but the metrics should be a good guideline. Look at the volume of support questions and if they are being resolved as well as ratings and number of downloads.

They are both rated as 4 out of 5 by

And who is eukhost?

There are several security plugins listed that have been widely adopted.

WP Security Scan is one I use.
