network appliance...

[jt () COVERTSYSTEMS COM (JT)]

has anyone heard of vulnerabilities in the Network Appliance base operating systems? they're the company that makes 
large filer head systems and my company is considering buying one. the operating system is unix or unix based but an 
nmap scan on known open ports in demonstration showed absolutely nothing - no operating systems id either. i was 
curious as to whether this is really as safe as it seems...

thanks,
