For the last time. The issue I'm speaking is not a Mutex problem but a problem with the technology the use. Go to and run Outbound on your ZA firewall. It fails miserably.

By all means continue running ZA but don't come back and complain if you get it in the end. Know what I mean? The only way to approach security is to be paranoid. And don't ever settle on what the vendor or some individual who happens to write for magazine has to say.
They are usually the ones without backups or virus scanning, etc. etc. etc.
