LuLu is an open source firewall tool for macOS。Can block outgoing network connections for any app，until you give us your permission。While LuLu is designed to detect malware generally by flagging unauthorized network connections，But it can also be used to prevent macOS components or third-party applications from transmitting information to remote servers。 feature 100% Free no ads，no time trial，No missing features。 it doesn't track、Spy or spy on you - because that's just pure evil! The full source code for open source LuLu is available on GitHub。This transparency allows anyone to audit their code，or understand exactly what's going on。 Protection LuLu is designed to alert you when unauthorized network connections are attempted。therefore，It can often detect malware，or to block legitimate applications that may transmit private data to remote servers。 Simple "do one thing"，Get it done! ” LuLu is designed to be as simple as possible。certainly，This means that complex features may not be available，But it also means it's easier to use and has a smaller attack surface! Business Friendly Wondering what network events are detected? Or rules added by your users? LuLu provides a simple mechanism to subscribe to such events，and open、Store data like rules in an easily digestible way。 Network monitoring by design，LuLu only monitors outgoing network connections。Apple's built-in firewall does a great job of blocking unauthorized incoming connections。 Rules Currently，LuLu only supports "process level" rules，This means that the process (or application) is either allowed to connect to the network，or be banned。As is the case with other firewalls，This also means that if malicious code abuses legitimate (allowed) processes to perform network operations，this will be allowed。 single user currently，LuLu can only be installed for a single user。A future version may allow multiple users to install it on the same system。 DEFENSE YOURSELF What Legitimate Attackers/Security Experts Know，Any security tool that is specifically targeted，can be easily bypassed - even if the tool uses advanced self-defense mechanisms。This self-defense mechanism is often complex to implement，It's almost always in vain in the end。therefore，LuLu has (currently) few self-defense mechanisms implemented by design。For example，An attacker can enumerate all running processes to find the LuLu component responsible for displaying alerts and terminate it
