AFAIK there hasn't been any serious securityriscs with d.net clients, and
considering the client only connects, and doesn't accept connections I can't
see what security riscs he's talking about.
BUT the d.net policy clearly states that you need the approval of the system
owner/admin/whatever to run the client, so if he says no, he says no...

You could try to persuade him to join d.net instead, or atleast get him to
set up a keyproxy, that way he could control the "permanent connections
to the internet" (which isn't true, the perprox or client only connects when
the buffers are empty/full or you tell it to, which hardly can be regarded as

Talk to your IT Manager and ask him if he can set up a keyproxy where he
can secure it as he pleases, that way he'll have a bit of control, just the
way we paranoid admins like it...
