Two companies that I do work for had unrelated data breaches. One was a more traditional hack on their database and the other was from a client giving a third party access to a secured database. I have very little information on the data breach is outside of that and I do not know the intentions of those involved. I would however like to monitor the web to see if any of the breached data shows up for sell. What are the best sites to monitor for the breached data? Are there any programs or services that could be utilized to monitor for this information?
