You know you have a secure connection when the URL begins with https:// -- the "s" stands for "secure."
On any other connection, your data goes through multiple routers (sometimes over 20) and lots of professional scammers install software to recognize SSNs and other personal data.
Obviously, don't post your personal identifying data at the CreditFactors MEMBER forum - limit your posts to the ACCOUNTS and SCORE FACTORS - nobody needs your personal data. It's not even rated by FICO scores.
Keep your personal data safe!
