Not a bad place for that question at all!
iVerify is a security app for iOS and Android focused on protection/detection of mercenary spyware like Pegasus.
It is primarily an enterprise service but they offer a consumer version called iVerify Basic anyone can download. It has a proven track record of detecting spyware infections though it is closed source and proprietary making some people in the privacy space uncomfortable with it.
I use it along side other defensive measures like Lockdown Mode and DNS filtering. Below is a link to iVerify’s website with more info.
