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!

Customer Reviews

I like it

1) This application runs alongside my antivirus.

2) They should tag this app in the antivirus search results.

3) A yellow button that says Close Warning would be better.

Great security app

This is the only app out there that tells you if someone is hacking your laptopn while your sitting in Starbucks. Very useful!

Doesn’t detect much

I was really excited to find this product. Unfortunately it doesn’t work as advertised.

1. It says it detects remote logins. I’m not sure what it means by this, but I logged in remotely to my iMac through SSH, VNC, and AFP and it didn’t detect any of these remote logins.

2. It detects port scans, but not in a useful way. It only allows monitoring of scans to ports 1024-5000. I want to know if someone’s scanning for my port 5900 for VNC or my port 22, or 445. No luck there.

3. It did detect when I used sudo in my terminal, but when I logged in remotely with ssh and used sudo it didn’t detect this.

4. When it does detect something, it gives you a brief notification. However, there is no option to notify you by email or imessage or anything useful like that.

5. When it does detect a port scan in the range 1024-5000, it doesn’t give you any helpful details about the event.

The app is definitely pretty and there is promise here, but I wouldn’t say it’s ready to be charging $5 for it.
