FortiOs Vulnerability assessment feature compared to other tools

[oliverlag]

Hi, 

I'm trying to figure out how good is the vulnerability assessment tool integrated in FortiOs compared to other tools like Nessus, OpenVas etc. 

I'm trying to find any review in internet but I'm not able to.. I just find top N best tools like this one: http://sectools.org/tag/vuln-scanners/ but Fortigate is never listed. 

is it because it's simply very basic and the vulnerabilities db not that complete? 

Thanks
