Zone Alarm Pro 5.1 has an exposed port ?

Well, even if there was an 'exposed' port then it wouldn't be visible behind the router unless you've forwarded any ports. Ask you friend to explain exactly what he means by an 'exposed port' in a bit more detail than his vague comments and post his explanation here.

Taking a moment's reflection, steve h. mused: | | I recently purchased ZA Pro to use with my router. I'm happy with | it. However, a friend of mine who repairs PC's told me that the software | firewalls are vulnerable to hacking because of a port they use. This | doesn't make sense to me, because I'm sure all the firewall companies are | aware of hacker tactics. How difficult is ZA to hack ? Thanks for your | time.

Unless your friend can provide a substantive answer to the that of "phoenix," I would cease taking computer advice from this friend. Because, unless he knows something the rest of the world doesn't, he's full of it.
