Current Version: 1.4.0 (March 9, 2004) / 1.6.4 (June 9, 2008)

The latest in a long line of network monitoring software from Sustainable Softworks, IPNetSentry is a simple and intelligent security application which protects your Macintosh from outside Internet intruders. This is particularly important for Macintosh users who have cable modem, DSL, or another high-speed Internet service where connections can be maintained and left unattended for hours (or days) at a time. Unlike most other Internet security products, IPNetSentry does not erect barriers for the safe use of your Internet connection. There is no need to "punch holes" in a firewall for specific applications you may wish to run. Instead, IPNetSentry silently and intelligently watches for suspicious behavior, and when triggered, invokes a solid filter which completely bans the potential intruder from your Macintosh.

Version 1.4.0 - the latest version for "Classic" Mac OS - makes the following changes:

  • Added payload inspection support for a second version of the SSLammer worm. This worm is a direct attack on TCP Port 443 and can be a problem for Web* and other servers which are running SSL services.

Version 1.6.4 - the latest version for Mac OS X - adds/changes the following:

  • Traffic Discovery: turn off TD explicitly if no previous setting was saved.
  • Preferences: added "Save to log interval" of 10 seconds.
  • Sentry Log: added timer to force periodic update at log interval.
  • Create symbolic link to daily security log named "security log today.txt"
  • Add "invalid" table under Trigger tab to remember source IP address of packets with short transport headers.
  • Rename "IPNetSentryX_startup.app" to "IPNetSentryX_startup" since it no longer contains an application, but rather a shell script.
  • Fixed problems with launching at startup or login time before interfaces have stabilized.
  • Fixed bug in checking code signature of admin only tools when run from non admin account.
  • If code signature is not verified and user chooses quit, re-install all tools on next launch to attempt repair.
  • Cleanup system.log messages when run from non admin account.
  • Lookup: add support for IPv6 and display any IPv6 addresses returned.
  • Lookup: added "Show DNS" button.
  • Tool history: keep 10 entries in addition to any suggested local configuration values.

User Reviews

"Smooth running and does a great job catching, then blocking, those nasty hacker wannabe's. IPNetSentry even lets you add custom filters to other ports of entry."

These are applications that are newer and of potential interest, but which I haven't yet selected for permanent inclusion. Have a look, and let me know if you think they deserve to be part of the permanent collection!
