The main competitors for Fortinet FortiNAC are Forcepoint and ClearPath. The main diffidence is Fortinet FortiNAC is more expensive but has better stability.

I've also looked at HP and compared the two solutions. HP is less expensive, however, it's not a huge difference. We're talking maybe a 1% to 2% difference in price if you compare them. A customer will pay more for HP if they do a POC. 

Cisco ISE has many tools on the same platform, with many functionality and features. We can troubleshoot and perform searches within Cisco ISE. FortiNAC only has network access control.

We evaluated Palo Alto, it is very good, however, it is difficult to transfer knowledge for the end user. Palo Alto also does not have email protection.

I have evaluated other NAC solutions.

We did not evaluate other solutions other than on a cost basis.

We evaluated so many other products but we found the features of this solution to be the most valuable.
