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.

Application security spans SAST, SCA, secrets and container scanning. See how AppSec differs from DevSecOps, why it's now board-level, and how Safeguard prioritizes fixes.
SAST scans source code for exploitable flaws before deployment. Learn how it works, how it differs from DAST/SCA, and where it falls short.
A stage-by-stage breakdown of how SAST scanning actually works — parsing, taint analysis, false positives — with real CVEs and benchmark data.
DAST tests running apps like an attacker would. Learn how it works, what it catches and misses, and how PCI DSS 4.0 now mandates it.
A 2026 buyer guide for enterprise SCA platforms covering language coverage, reachability, policy depth, integration surface, and how the consolidator market is shifting.
IAST instruments running apps to catch injection flaws and unsafe data flows in real time. Here's how it works, its limits, and where it fits.
RASP blocks attacks from inside a running app. Learn how it works, how it differs from a WAF, its limits, top vendors, and where it fits with SAST/SCA.
SAST reads code before it runs; DAST attacks it while it's live. Here's what each catches, what each misses, and when to run both.
