Why ShieldedStack Matters

The Last Line of Defense for Your Software Supply Chain

Block malicious and outdated packages before they reach your developers—without slowing them down.

  • Real-time CVE scanning & blocking
  • Age-based risk & legacy detection
  • Zero friction for developers
  • Centralized visibility & control

The Hidden Threat in Your Code Dependencies

Every npm install and NuGet package download is a potential backdoor into your enterprise. Between 2019 and 2022 supply chain attacks surged 742% and it’s only getting worse. Attackers increasingly target the open-source packages your developers trust most. The SolarWinds, Codecov, and event-stream attacks exposed a harsh reality: your security is only as strong as your weakest dependency.

The typical enterprise downloads thousands of packages monthly. Without visibility and control, each download could deliver malware, data exfiltration tools, or backdoors directly into your production environment.

This isn’t a theoretical risk. The numbers expose the scale of the threat facing every modern development team:


512,847
Malicious packages discovered since Nov. 2023
156%
YoY growth of malicious packages
4.5
Trillion
JavaScript (npm) requests, 70% YoY growth
530
Billion
Python (PyPI) package requests, 80% YoY increase largely driven by AI & cloud

Repository scanners see your commits, not the packages your teams trial on the network

Dependabot and other repo scanners do great work once code is checked in, but your developers pull countless packages locally long before anything reaches Git. Those ad hoc downloads are invisible to traditional tooling—and they are where weaponized packages love to hide.

ShieldedStack closes that blind spot by sitting on the company network path to npm, PyPI, NuGet, and more, blocking risky artifacts the moment someone tries to install them.

ShieldedStack: Your Intelligent Supply Chain Proxy

ShieldedStack sits invisibly between your developers and package managers (NuGet, npm, PyPI), acting as an intelligent security gateway that blocks malicious packages in real-time before they reach your codebase.

  • Intercepts Every Request: All package downloads flow through ShieldedStack's proxy
  • Real-Time CVE Scanning: Correlates leading vulnerability intelligence to surface emerging threats instantly
  • Age-Based Risk Assessment: Flags outdated packages with accumulated security debt
  • Intelligent Blocking: Automatically denies packages with critical vulnerabilities, suspicious patterns, or dangerous legacy versions
  • Zero Developer Friction: Works transparently with existing workflows—no changes to developer tools required

Complete Visibility & Control

ShieldedStack's hosted security console delivers end-to-end visibility and guided response with:

  • Unified Package Intelligence: Track every package and version in use across your organization
  • Actionable Vulnerability Reports: Map CVEs to affected projects with prioritized remediation guidance
  • Legacy & License Insights: Spot outdated dependencies and high-risk licensing trends before they escalate
  • Policy Workflows: Tune allowlists, denylists, and severity gates without slowing developers
  • Audit-Ready Trails: Preserve every package decision for compliance and post-incident reviews
  • Team-Friendly Exports: Share dashboards and reports with security leadership and engineering owners

The Business Impact

  • Block compromised packages before they enter your environment
  • Eliminate security debt from aging dependencies
  • Reduce incident response costs by stopping attacks at the source
  • Maintain compliance with software supply chain security requirements
  • Accelerate secure development without slowing delivery
