LuLu (by Objective-See) is an excellent free outbound firewall — CoreLock complements it with malware scanning, permission audits, and certificate checks LuLu doesn't do
LuLu asks you to allow or deny each connection yourself; CoreLock analyzes behavior and tells you what's suspicious and why
LuLu is open source and donation-supported — if you only need outbound blocking, it's a great choice
Many users run both: LuLu to block, CoreLock to scan, audit, and explain
They do different jobs. LuLu is a free, open-source outbound firewall that asks you to approve each new connection. CoreLock is a broader security scanner: malware detection, privacy permission audits, code signing verification, and network monitoring with plain-English explanations. If you want one tool that scans and explains, use CoreLock; if you specifically want rule-based outbound blocking, LuLu does that and CoreLock doesn't.
Yes. LuLu blocks connections at the firewall level while CoreLock monitors processes, scans files, and audits permissions. They don't conflict, and together they cover both prevention and detection.
You don't have to — CoreLock's free tier (3 scans per day) is permanent. LuLu is and will remain free, but it only handles outbound connections. CoreLock Pro ($4.99/month) adds unlimited scans, AI analysis, and one-click auto-fix — capabilities LuLu doesn't aim to provide.
