Spear phishing

It’s been about a year since people started publicly talking about spear phishing attacks against ESPs and major emailers. There was a lot of energy put into talking about how to protect against future attacks. I have to wonder, though, how much of that talk translated into action?
What processes do you have in place to protect your company against attacks?
If you’re at an ESP, do you have the ability to scan your outgoing stream for keywords or domains?
If you’re a brand, have you implemented restrictions on which employees have access to your databases?
What have you done since the last set of attacks? Are you vulnerable if new attacks start?
