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.

Pass an auth dependency to FastAPI(dependencies=[...]) or to an APIRouter so every route inherits it. Why that beats adding it per route, and what to test.
A side by side table of documented defaults for body size, params, trust proxy, timeouts and proto handling in Express and Fastify, and what to set.
Export the repository dependency graph as an SPDX file from the Insights tab or an Actions workflow, then date it, name it and note what it covers.
When a developer says a vulnerable function is never called, turn the claim into a check: find the entry points, trace the calls, and record the result.
Plain words for a security reviewer: CI proves who it is and gets a short lived token, so no long lived cloud key sits in your pipeline secrets.
Use distinct exit codes for clean, findings found and tool error, so a pipeline never mistakes a crash for a pass. A short design guide for CLI authors.
Exclude a path when code never ships, like fixtures and samples. Suppress a finding when code ships but one issue does not apply. How to choose.
Store exception expiry as a UTC timestamp, show local time and define start or end of day. This avoids arguments, surprise build breaks and confusion.
