    Breathe easy

    Part of why we all love using our computing devices in public spaces is the atmosphere, be it a coffee shop or university lawn. It helps us focus on our work. We shouldn't have to be concerned about the network security implications of working on a public WiFi connection.

Protect your computer and data from network threats

4Shadow notifies you when any of the following threats are detected.


Remote Login Attempts

Attackers may try to guess your computer password and gain remote access to your system and documents.


Network Poisoning

Also known as "Man in the Middle" attacks, the network can be taken over to redirect your connection to an attacker's computer, exposing your passwords and data.


Privilege Escalation

If an attacker manages to gain access to your computer, they will often try to perform actions that require administrator privileges - you will be alerted if this ever happens without your knowledge.


System Misconfigurations

4Shadow will check that security features of macOS are enabled.
