API gateway security: enforcing authN/authZ and rate limits at the edge
A single unauthenticated API endpoint exposed 37 million T-Mobile accounts in 2023. Edge-enforced authZ and identity-aware rate limits are how you prevent the repeat.
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.

OWASP's 2023 API Security Top 10 lists 10 risk categories — most start with a single curl request. Here's how to test and fix each one.
A 2025 USENIX study found LLMs hallucinate nonexistent packages in up to 21.7% of code samples — and attackers are already registering the names.
Docker's default seccomp profile blocks roughly 44 of the 300-plus Linux syscalls, yet a 2019 runc escape bypassed every default namespace boundary anyway.
.NET 8 gave containers a built-in non-root user and chiseled images that cut one team's CVE count 92% — most Dockerfiles still don't use either.
The official node image ships a built-in non-root user, but COPY still writes files as root by default — most Node.js Dockerfiles never actually drop privileges.
Log4Shell (Dec 2021) and the XZ Utils backdoor (Mar 2024) exposed two different SDLC failure modes. An 8-point framework closes both.
GitLab's 2017 outage revealed 5 backup mechanisms had silently failed for weeks — recovery took 18 hours because no one had ever test-restored one.
DR plans fail when they're never really tested. Here's how tabletop, simulation, parallel, and full interruption tests differ — and when each is worth the risk.
