Intercept and block malicious package versions before they execute, closing the hours-long gap between compromise and detection.
Added Apr 12, 2026

Software supply chain attacks on package registries like npm are accelerating, with compromised packages deploying malware within seconds of publish while existing security tooling takes hours to detect threats. Developers currently have no interception layer — running npm install blindly executes postinstall scripts, downloads payloads, and calls home before anyone notices. High-profile incidents like the Axios compromise (100M+ weekly downloads) demonstrate that static analysis and manual review are far too slow.
A runtime package installation guard that sits between the developer and the package registry, intercepting installs in real-time. It combines manifest diffing, sandboxed install execution with network monitoring, behavioral pattern matching, and kernel-level observability (e.g., eBPF) to flag suspicious packages before they touch the host system. Packages are scored and blocked or quarantined automatically, closing the detection window from hours to seconds.
Major supply chain attacks (Axios, xz-utils, ua-parser-js) are hitting mainstream packages with increasing frequency, and recent high-profile incidents have created urgent demand for proactive defenses. Regulatory pressure (EU Cyber Resilience Act, US executive orders on software supply chain security) is pushing organizations to adopt automated safeguards.
