As vShield Zones is going end of life in August 2013 I am in need of an alternative firewall product on which I don't have to spend a fortune (like upgrading my Enterprise licenses to Enterprise Plus, then buying vCloud Networking and Security).
Does the community have any recommendations for alternative software, vmware friendly firewalls that I can use? The main features I'm looking for are the ability to create many (40+) security zones and firewall rules.
