4Shadow

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!
