Let me start off by saying that I love Liferay but I'm not blinded by it. Our website runs it and runs comfortably but I'm not in the financial sector any more. My background is mostly financial sector and DOD. I'm also a CISSP. Because of that, I have a very good idea about what your needs are. Been there, done that, got the T-shirt... the stuff animal... and the beach towel.
For example...
There are issues with the https stuff... either logging people out or not working.
NT authentication will allow the user to put in ANY password and still authenticate them. As long as you have a valid user name, you're in.
I'm having an issue right now because when you activate Staging so that you can turn on Workflows, you have to grant "Manage Pages" to allow people to edit. "Manage Pages" isn't a Community Right... it's a portal right.
Search will give up items that you don't have access to.
There are others... I would strongly advise that you test it thoroughly before you deploy it in production environment with sensitive information on it.
