Need a DLP for a mix of Operating systems

hi, 

This is a combination of Sales and Tech question. 

We are exploring a DLP solution to be run on individual laptops at workplace. We use a mix of systems (Roughly around 50 windows, 10 macs, 20 ubuntu). Can you please advise on whether this is feasible and if so how do I go about it? (I have logged a request under "Contact Us" too). 

Secondly our license period for the anti-virus solution is nearing its end. So in light of above, wanted to know if there is just one license that can cover anti-virus/malware as well as DLP or are these to be bought separately. 

Thanks
