What is ShieldedStack?

ShieldedStack is an intelligent security proxy that sits between your developers and package managers (NuGet, npm, PyPI). It intercepts every package download request, scans for known vulnerabilities in real-time, and blocks threats before they reach your codebase—all without slowing down your developers.

For Development Teams

  • Zero configuration changes to existing workflows
  • Transparent package downloads with automatic protection
  • No slowdown in development speed

For Security Teams

  • Complete visibility into all package usage
  • Centralized policy control and enforcement
  • Audit trails for compliance requirements

How ShieldedStack is Different

Traditional Repository Scanners

(Dependabot, Snyk, etc.)

  • Scan after packages are committed to your repository
  • Miss packages developers test locally before committing
  • Vulnerable code already on developer machines and network
  • Alert you to fix issues after the fact
PROACTIVE

ShieldedStack

(Network-Level Protection)

  • Blocks before packages reach your environment
  • Intercepts every npm install and package download
  • Vulnerable packages never touch your network or machines
  • Prevents problems before they start

ShieldedStack gives you both: Network-level blocking + Package Scanner for existing code.

Why This Matters: The Hidden Threat in Your 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

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 scans for known vulnerabilities and blocks threats in real-time before they reach your codebase.

  • Intercepts Every Request: All package downloads flow through ShieldedStack's proxy
  • Real-Time Vulnerability Scanning: Instantly checks packages against our vulnerability database
  • Age-Based Risk Assessment: Flags outdated packages with accumulated security debt
  • Intelligent Blocking: Automatically denies package versions with known vulnerabilities based on your severity thresholds
  • 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
