Information Rights Management in Reflexion

Hi,

I am a new Reflexion customer that has not switched over our MX records to Reflexion yet but plan on doing so in the next week or so.

One question I have about Reflexion is whether or not it has Information Rights Management functionality built-in or if I need to rely on our internal Active Directory/Domain policies to handle this? It's a function we're currently not using at the moment but upper management has asked for it and don't want to do double work if not needed. Also, we're Office 365 for our email but use on premise AD for syncing usernames/passwords (ADFS).

Just for reference, this is the functionality I'm wanting to use: https://technet.microsoft.com/en-us/library/cc178985.aspx

Thanks!
