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 those at coffee shops, hotels, airports, and universities, or simply for those looking to increase the security posture of their system.

Open 4Shadow, perform minor initial configurations, minimize, and then continue with your daily activities with more confidence that your system is being protected!
