Freeware software on product environment

Answer: ISO 27001:2013 does not define what can or cannot be allowed/accessed in an organization, but requires that any decision made is based on the results of a risk assessment, applicable legal requirements and top management decision. So, you should consult these sources to verify if you can allow/access freeware on production environment.

What I can tell you is that some freeware have licenses that forbids them to use in commercial environments (you have to use the paid version), so you should consult the terms of the software you are considering.
