Nope, unless you Jailbreak your phone you don't require anything. In iPhone you are practically using the phone as a standard user and not as an administrator so apple doesn't let you touch anything related to the OS.
These companies may provide additional services (ie. Prevent Data loss or Theft) included for free or require a fee, but they will require you to register an account with them. Note, Apple can provide this for free as it's built-in to iOS/iCloud.
