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.

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.

Each arrival is an execution, and none of it was reviewed by anyone on your team.
Five entry points. One unchecked component is enough.
One policy, enforced everywhere the component travels, so it is inspected before it runs, merges, builds or spreads across the org.
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.
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.
SafeDep MCP checks each package an agent wants before it installs. The advisory trail shows which agent asked for what, so a malicious pull is attributed rather than anonymous.
vet inventories what each machine actually has loaded: coding agents, MCP servers and CLI tools, with scope and version. None of it appears in a lockfile, so none of it shows up in a repo scan.
The GitHub App posts a summary on each pull request: malware, vulnerability and license checks, with a verdict per package. It runs as a required check, so nothing reaches main unreviewed.
SafeDep runs as a proxy in the pipeline and intercepts every package install. A malicious package is stopped before it reaches the runner, and the job exits non-zero on the policy violation.
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.
The command-line tools that do the actual blocking. Free forever, and yours to read.

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.
Malware
Version 13.3.0 of @ethersphere/bee-js, the JavaScript client for Swarm, added a postinstall hook that steals the Swarm node wallet key and installs a remote-access backdoor. Swarm Desktop 0.56.2 shipped the same loader.
Malware
19 npm packages carry a Miasma-family worm that steals credentials, spreads to other packages and installs a wiper. The latest wave plants instructions in GitHub repositories that tell AI coding agents to run the worm.
Security
A fake take-home assignment replaced a Homebrew binary on a Binance work laptop. SafeDep rebuilt that setup step as a benign lab and ran it with and without the pmg sandbox. The post gives the commands, the real output and the limits of the sandbox.
