well we don't even work onsite. I write my code on my company laptop. Test against a sanitized database on my companies network and whatnot. Then commit to my companies source control. Then I pickup my government issued locked down laptop, vpn in, remote desktop to the server across the US and svn-update.

I am not dealing with TS stuff here. There are files on the government network which are confidential and having access does require a clearance, but I don't actually work with confidential data directly.
