SafeDep Threat Intel is liveThreat Intel is liveExplore

Your biggest AppSec blind spot is the code you never wrote.

Attackers don't target your code. They target what you install: packages, MCP servers, IDE and agent extensions. SafeDep blocks malicious packages at every entry point, before they run.

Caught in the wild

This isn't theoretical.
We find it in real time.

SafeDep analyzes every package published to the major registries, around the clock. Our research team publishes the breakdown, often before the ecosystem has an advisory.

The problem

Malicious code doesn't break in.
It gets installed.

Third-party code arrives at every hand-off in your pipeline, from a developer's terminal to an org-wide registry. Each arrival is an execution, and none of it was reviewed by anyone on your team.

  1. Developer machine

    What gets in
    • npm / PyPI installs
    • IDE extensions
    • MCP servers
  2. AI coding agent

    What gets in
    • agent skills
    • plugins
    • tools it invokes
  3. Repository / PR

    What gets in
    • new dependencies
    • transitive deps
  4. CI/CD pipeline

    What gets in
    • build-time pulls
    • base images
  5. Registry / org-wide

    What gets in
    • everything pulled
    • shared caches

Five entry points. One unchecked component is enough.

The answer

SafeDep guards the same five stages.

One policy, enforced everywhere the component travels, so it is inspected before it runs, merges, builds or spreads across the org.

  1. Dev machine

    Blocked on install

    malicious package firewall
  2. AI agent

    Blocked in-agent

    skills, plugins, MCP vetted
  3. Repo / PR

    Blocked at PR

    policy check on new deps
  4. CI/CD

    Blocked at build

    gate before artifacts ship
  5. Org-wide

    Blocked org-wide

    one policy, every team
Why SafeDep

Pick a layer.
See what SafeDep does there.

Credential theft, reverse shells, data exfiltration. These are purpose-built attacks, not bugs a vulnerability scanner can match against a database. Every screen below is the real product.

Block the install, on every machine

SafeDep sits in front of npm, pnpm, pip, uv, bun and other package managers and blocks malicious packages at install time, before any post-install script runs. Every decision lands in one fleet view, alongside a live feed of what was just blocked and where.

  • Refused at install time, not flagged next week
  • Laptops, CI runners and servers in one view
  • Live feed of blocked packages, per endpoint

Every enforcement point is open source and auditable, so there is nothing to take on trust. SafeDep Cloud is what turns those same tools into protection for a whole organization.

For the security team

Everything in the open source tools, plus the org-wide layer: which components exist, who pulled them in, what policy blocked what, and proof for the audit.

  • One policy enforced at every entry point
  • Org-wide inventory and component lineage
  • Exceptions, approvals and audit history
  • SSO, tenants and role-based access control
