Security concerns of using the Node.js VM module as a sandbox
Node's vm module and vm2 were never a security boundary. Four critical CVEs and a 2023 deprecation prove why untrusted-code sandboxes need real isolation.
Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.

A maximum-severity vulnerability in Erlang/OTP's SSH server allowed unauthenticated remote code execution. Any system running Erlang's built-in SSH daemon was at risk, including telecom infrastructure.
OWASP's Top 10 for LLM Applications reframes AI risk around prompt injection, data poisoning, and supply chain gaps that container-only tools like Aqua can't reach.

SAST and DAST test different layers of an application at different stages of the pipeline — the real question isn't which to pick, it's how to run both without duplicating effort.
Five layers cover most of the risk in cloud apps: identity, secrets, artifact scanning, pipeline gates, and runtime guardrails. Here is how to build each one without slowing delivery.
Recent macOS versions ship without Python at all, so opening Python on a Mac now means installing it yourself — and doing that safely matters more than most guides admit.
