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 proxy the workload can decline to use is a log, not a control. Why environment-variable proxies and host firewall rules both fail for untrusted code, and the internal-network plus gateway-container shape that does not.
Kubernetes operators run with broad cluster access. This checklist covers the controls that matter most in 2025, from RBAC scoping to image provenance.
In April 2019, Docker Hub exposed 190,000 accounts' credentials and GitHub/Bitbucket tokens. Here's what happened, what leaked, and why it still matters for supply chain security.
Researchers estimate roughly 3% of public Docker Hub images carry malicious payloads. Here's what's inside them, how they spread, and how to defend your pipeline.
A look at why Docker Hub's most-pulled base images still ship hundreds of known CVEs, and how reachability analysis cuts the noise down to what's actually exploitable.
Cryptomining malware keeps resurfacing in public Docker images. Here's how attackers hide miners in plain sight — and how to catch them before they run.
Attackers are cloning popular Docker Official Images under lookalike names, tricking `docker pull` into fetching malware instead of trusted base images.
Container images have become the software supply chain's most contested attack surface. A look at the xz-utils backdoor, registry-borne malware campaigns, and the detection gaps behind them.
A 2026 look at Alpine vs. Debian base image CVEs shows raw vulnerability counts mislead — patch cadence and reachability matter more than distro choice.
