Security (IPS) and Dreamhost


I’m looking at signing up with DreamHost and would like to know if you’re using any kind of intrusion prevention system (IPS). If I’m going to host a merchant account, shopping cart, etc. with the way the laws are going where I’m at, it’s almost (if not) required to have some sort of “checking” and better yet a “preventative” system in place for monitoring and stopping intrusions (hacks, etc). What does DreamHost do to protect their customer’s data?

I understand some of this information could be considered sensitive, but I must know that my data will be secure where it will be hosted (would’ve asked in person but there’s no phone number to contact DreamHost at).

Thanks in advance.
