I'd guess the EU's cyber agency is relevant, if only because it does some of the EU-wide coordinating. And because the smaller and poorer EU nations can't afford much on their own.
Might anyone here be familiar?
After that - in a giant bureaucracy, head count is a very poor measure of effectiveness. Would upping the agency's head count do much good. Or are there structural problems which will make that (by itself) mostly a waste of funds?
