Answer:
The most appropriate response is that your friend should contact the marketing department and let them know that he wants access to the beta release.
If you are not in charge of the marketing department, then, you should not, by all means, distribute the beta software to one your friends. This would be against the firm's policy, would probably cost you your job, and could even lead to legal liabilities.
The information channels and the firm's protocols should be respected by all employees, and they should not be breached because of nepotism, friends, or outside influences, because that would essentially be corruption.
