Set an expiration date in a PDF

Is there a way to do this in native adobe acrobat DC?  Or do we need to buy another product?

You can do it in Acrobat using a script, but there are ways around it. If you want a secure solution then you need to use DRM technology to achieve it.

Any recommendations for a low cost DRM?
