Sustainable Softworks is now shipping IPNetSentryX for OS X. IPNetSentryX is a utility designed for firewall protection. The newly ported OS X version features support for content based rules and custom trigger definitions for intrusion alerting. According to Sustainable Softworks:
Sustainable Softworks today released v1.0 of IPNetSentryX, an Internet firewall application for Macintosh computers running Mac OS X. What makes IPNetSentryX so unique is the ability to easily define hierarchial firewall rules.
Like most conventional firewall products, including Appleis own built-in Personal Firewall, IPNetSentryX rules can be based on IP addresses, ports and protocols (services). But unlike conventional firewalls, IPNetSentryX also lets users base rules on the content of incoming datagrams (e.g. to detect worms).
More importantly, IPNetSentryX easily lets users define which actions to take when rules are met. Such actions can be as simple as blocking an intruder (trigger), alerting you of the intrusion, sending off an email message pertaining to the intrusion, running a designated AppleScript, or any combination of the above.
