CUSpider

CUSpider can scan a computer for social security numbers, credit card numbers, or other PII, and produce a list of resulting files with remediation options that you can immediately take. Its graphical interface is very user friendly, and the settings can be modified to send results to a central server for collection.

Crawler Perl script

Download a copy of the Crawler Perl script that Columbia's ISO uses to scan central servers for personally identifying information (PII). It seems to do a better job keeping track of changes, and as such is better suited to regularly scanning large servers. Unless you're familiar with command prompts and piping output, you may want to try Spider's GUI. Not to be distributed.
