I wonder if he is including CyberGuard's entry level hardware firewall in that.....

Seems a bit self serving for an officer at a company which produces an entry level firewall, suggesting that consumers should not trust them.... except for our own of course.

Also, this makes me a bit suspicious

CyberGuard firewalls have zero vulnerabilities.

Sounds a bit unrealistic to me, although I have not really investigated their firewalls too much.
