For most companies it is less than you would think. We charge by the hour for our services in 15 minute increments and we DO NOT charge while our tools are running in "auto-pilot" or gathering information. A good rule of thumb is that it takes about an hour to audit a workstation and 2-3 hours to audit a server (Windows- for other Operating Systems contact us). We also audit Firewall configurations, Switch/Router configurations, Wireless AP configurations (a favorite of hackers to exploit) and much, much more.
