Your Mac's Silent Guardian
Four layers of malware detection — hash matching, YARA rules, behavioral analysis, and code signing verification — all running offline with zero data collection.

Four Layers of Defense
Every file is analyzed through multiple detection engines, catching threats that single-method scanners miss.
Hash Matching
Compares file hashes against known malware databases for instant identification of recognized threats.
YARA Rules
Pattern-based scanning using industry-standard YARA rules to detect malware families and variants.
Behavioral Analysis
Examines file behavior patterns and suspicious characteristics without executing the file.
Code Signing
Verifies Apple code signatures and notarization status to detect tampered or unsigned binaries.
