Should I freeze my credit?

I was made aware that my personal information, including SSN, might have been compromised in a data breach. They did not confirm or deny the possibility as of now. That natural worrier that I am....my head has been spinning.

Is there some sort of entity like lawyer, credit bureau, etc that I can go to for advice? I've ran my credit report and found nothing unusual. But I'm wondering if I should proactively freeze my credit just to be safe. Any advice would be very much appreciated as I'm a nervous wreck....
