ShieldedStack vs Dependabot
Dependabot is GitHub's built-in dependency update tool—widely used, free, and convenient. But it operates after vulnerable packages are already in your repository. ShieldedStack stops them at the gate.
Reactive vs Proactive: Where Each Tool Intervenes
Dependabot
GitHub Dependency Update Alerts
Dependabot monitors your repository's dependency manifest files and opens automated pull requests when a dependency has a known vulnerability or a newer version is available. It is deeply integrated with GitHub's ecosystem and requires no infrastructure setup.
- Only scans what is committed to GitHub—misses local developer installs
- Vulnerable packages exist in your environment while you wait to merge the fix PR
- No enforcement—developers can ignore or dismiss alerts
- GitHub-only—does not cover GitLab, Bitbucket, or non-hosted environments
- Cannot block new installs of flagged packages
ShieldedStack
Network-Level Package Proxy
ShieldedStack intercepts package downloads across ten ecosystems, applying workspace-level CVSS thresholds with severity fallback and expression-aware SPDX identifier deny/block rules.
npm · NuGet · PyPI · Maven · Go · Cargo · RubyGems · Dart · Composer · Hex
- Blocks packages before they reach developer machines or CI
- No remediation delay—blocked packages never need a fix PR
- Hard enforcement—policy violations are blocked, not just flagged
- Works across any git host, CI system, or on-prem environment
- Covers npm, NuGet, PyPI, Maven, Go, Cargo, RubyGems, Dart, Composer, and Hex in a single policy console
- SBOM export in CycloneDX and SPDX 2.3 JSON; vulnerability data is CycloneDX-only.
- Built by an EU-based company for global software teams

The Dependabot Alert Backlog Problem
Teams running Dependabot at scale routinely accumulate hundreds of open security PRs. Each one requires a developer to review, test, and merge—a process that can take days or weeks, during which your environment remains exposed.
ShieldedStack flips this dynamic: vulnerable packages are blocked at install time, before they land in your repository.
Used together, Dependabot handles automated version bumps for non-security upgrades while ShieldedStack blocks CVEs that meet the workspace-level CVSS threshold (severity fallback). Risk reports cover security, license, maintenance, and outdatedness, alongside first patched versions, upgrade guidance, and license checks.
