## AI overview

SCA tools address malicious packages through different signals and at different stages. Aikido combines a known-threat database with SafeChain, which proxies package-manager downloads and applies a default 48-hour package-age rule; Socket analyzes package behavior and offers install-time Firewall blocking, though its free tier blocks only human-confirmed threats. Sonatype Repository Firewall checks packages at a Nexus proxy, so it requires that infrastructure. Snyk flags packages cataloged by its researchers but does not analyze package behavior, leaving uncataloged threats undetected. SonarQube Advanced Security checks live threat feeds and can fail quality gates, but requires a paid Enterprise offering. Behavioral signals can flag legitimate packages, while threat feeds depend on discovery. The text recommends evaluating tools against real packages and notes that no product provides full coverage.
