A continuous monitoring service that watches npm package registries for anomalous activity: unexpected new dependencies, mismatched GitHub-to-npm release workflows, suspicious postinstall scripts, and never-before-seen transitive packages. It combines manifest diffing, sandboxed install behavior analysis (network calls, file system changes), and publish-pattern heuristics to flag compromised versions within minutes. Teams receive instant alerts via Slack, webhook, or CI pipeline integration with one-click lockfile rollback recommendations.

The March 2026 Axios attack—affecting a package with 83M+ weekly downloads—proved that even the most trusted packages are vulnerable and that existing detection takes hours. Developer teams are urgently seeking proactive defenses as supply chain attacks grow in frequency and sophistication.
