They should demonstrate that and not just make claims you have to take their word on.
This is hilarious to read, they're claimimg to have detected Pegasus spyware via a mobile app 🤣 https://iverify.io/blog/why-i-joined-iverify

It's simply not possible with the way Android and iOS apps work (app sandbox). The author of that article is complaining about the fact that Apple/Google don't give security software special access (so they can't sell their scam as easily). The real attack surface comes from highly privleged EDR software like CrowdStrike (and iVerify if they gkt the access they wanted), not mobile phones.
So what is this iVerify app? Just a promise with progress bar?
On iOS it literally notifies you instantly when there's a system update rather than waiting longer due to staged rollouts. On Android it scans installed apps for known malicious APK hashes. I think you can also send DNS requests through it via VPN service. Not that useful at all and can be achieved for free via other means (Google Play has Play Protect so it does the same thing), definitely not fighting off Pegasus spyware.
