4Shadow provides real time analysis of potential malicious network activity, host-based anomalies, and system configuration checks, with alerting using the Notification Center. 4Shadow is a must have for individuals who often use public insecure networks such as at coffee shops, hotels, airports, universities, or simply for those looking to increase the security posture of their system. Because 4Shadow runs in the OS X Application Sandbox, users can rest assured that 4Shadow itself will not give an attacker an opportunity to compromise their systems.
Open 4Shadow, perform minor initial configurations, minimize, and then continue with your daily activities with more confidence that your system is being protected!
What's New in Version 2.2
New "clear all" button to delete all alerts.
New icon for network safety button.
Dark-mode compatible system menu icon.
Shows process name for open port alerts.
Fixes issue where 4Shadow would sometimes identify itself when looking for open ports.
Claims Firewall is disabled but it’s not!
My biggest gripe is the annoying alerts that cannot be dismissed saying my Ffirewall is Disabled, which it isn’t and they cannot be removed or cleared until I went to 4Shadow’s Preferences and changed it from “Default Apple Firewall” to “Apple Firewall”. I‘m not sure what the differences are but after I removed the incorrcet warnings I set it back to “Default Apple Firewall” which did not remove the warning after a reboot. Switched to “Apple Firewall” in 4Shadow’s preferences pane and again, on reboot the warning cannot be cleared unless I continue to annoyingly open 4Shadow’s preferences.
Update: I changed it to “Apple Firewall” went into 4Shadow’s Preferences>Network Safety>Advanced and white listed some ports which I should’ve done sooner and I changed my rating to 3 stars since that seemed to dismiss the firewall is disabled error. Well, several days later that same irritating firewall is disabled issue is back again! So. it’s back to one star till they update & fix the issue. Looks like I might just uninstall it for a while, possibly forever.
I had asked a security expert what his thoughts were on 4Shadow: “...the MIM protection is great defending against a 2000 era Arp attack…but in no way protects your traffic from WIFI eavesdroppers.” If this is true then I’m sure near future updates to 4Shadow will not only improve protection for the user but performance and squash nitpicky bugs.
Can not white list process
Like app. Nice to see processes that are reaching out to internet, or escalating their privileges. Need more whitelist control.
Background: I wanted to keep my eye on a few processes before I decided if I wanted to whitelist them, or not (e.g., offfice365service). Now that I have decided I am not too worried, I can’t get the app to give me the whitelist option again.
Sorta expected that functionality to be there.
