My father runs a small business and has had a growing concern about some of the web activity for a couple employees. He's asked that we have a way to report the activity, but its a bit over my head. Probably the most important part of this is that it is for a "small business" (less than 15 employees) and whatever the solution is would need to be cheap, but effective.
Any recommendations for this?
EDIT
The budget needs to be in the $250 to $500 ball park. If the only options out there are all $1500, that would require some value proposition questions by the owner/father. So cheap is always better, but effective.
The office basically consists of a single server with 10 laptops/pcs. The server acts as the domain controller, application host (IIS stuff), SQL Server, exchange, etc. We do have a CISCO "PIC" device that is used as a firewall.
