IOS Certificate legitimacy

Hi,

I have 4 certificates in my “Certificate Trust Settings”.

1). Microsoft Intune Root Certification Authority (2 of these). I believe this is tied to the apps I downloaded to access my employers data via my phone.

2). AriesRoot. I have no idea what this is for.

3). SC_Online_Issuing. I have no idea what this is for.

In General > Profile, I have the Spectrum WiFi which I purposely added, but that is it.

I don’t see a way to delete the Certifications, although they can be disabled. I haven’t yet tried rebooting my phone after disabling them, so I don’t know if they’ll automatically revert back to being enabled.

How can I find out if these Certificates are legit? How can they be permanently removed?
