If it's your own website, you don't need a crawler. You have the full content in a nicely structured set of folders or - more likely - in a well-structured database. Crawlers rely on interpreting html like a browser does. No need for that in that case.
Just use tools for file searching and database querying.
Or am I missing something?
I am looking for a website crawler tool similar to how spider crawls files where you can search for any PII (SSN's, Credit Cards, etc.) being posted.
I want to ensure that no one is posting any PII information on our wiki.
