So my parents have a small company (approx 8 employees) and my mother told me about some security check they got done on their network. That is about the extent of the detail she gave me. She said something about in order to pass it they had to promise to get a network analyzer. The company has a server that holds information on clients etc. Naturally, my parents came to me being the comp sci student to take care of it. I've never even heard of one until now. I'm not sure what I'm looking for and what the purpose is. I did a few searches and it seems like there are hardware and software network analyzers but they seem pretty different. Any help/suggestions would be appreciated. Just kind of lost atm.
