Moonlock is a Mac protection and antivirus app made for individual Mac owners who care about their online security. It protects Mac users against Mac-specific malware and helps them better understand cybersecurity.
Moonlock was born from a simple belief: everyone deserves to feel safe and confident online without having to be a security expert. The app combines powerful protection with a user-friendly, beautiful, and intuitive design that challenges traditional expectations of what an antivirus tool should look and feel like.
Moonlock’s launch addresses a rapidly growing need for Mac security. A recent Moonlock survey shows that 66% of Mac users have encountered at least one cyber threat within the past year, while Mac malware detections increased by 20% in 2024 compared to 2023. In 2025, malware became one of the most common threats affecting macOS users, second only to personal data breaches. Over 80 countries were impacted by large-scale Mac stealer campaigns last year, alongside a significant rise in macOS backdoor (+67%) and stealer (+17%) variants. The long-standing myth of a malware-free Mac is no longer relevant.
Moonlock protects Mac users with Malware Scanning and Real-Time Protection — two powerful separate layers of Mac defense:
– Real-time protection provides continuous search for malware that runs 24/7 in the background. It responds instantly to malware attempting to enter through scam links, phishing websites, or fake Apple security alerts. Once detected, malware is neutralized and securely locked in Quarantine, preventing any harm until it is removed.
– The Malware Scanner allows users to scan their Mac on demand, detecting dormant malware and malicious files that are not actively running. It is designed to ensure nothing remains hidden across the system, folders, long-forgotten files, or even Mail attachments.
Moonlock’s malware database is built on hands-on research by Moonlock Lab, the company’s in-house team of malware investigators. The team has uncovered new malware samples and AMOS variants, tracked stealer developers, and exposed large-scale malvertising campaigns. Notably, Moonlock Lab experts were the first to report on the backdoor added to Atomic macOS Stealer (AMOS). Based on these findings, the Moonlock team continuously updates the app to protect users from the latest threats.
Independent experts have verified Moonlock’s ability to detect any malware in the world. The app is verified by the independent testing lab AV-TEST and notarized by Apple, ensuring its reliability.
