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.
FastAPI shipped a built-in DI container in its very first release in December 2018 — but the same swappability that makes DI testable can quietly ship a mock into production.
DOM clobbering lets attackers hijack JavaScript logic using pure HTML — no <script> tag required — and it just bypassed DOMPurify's own sanitizer in 2026.

HTTP/2 Rapid Reset hit Google with 398 million requests per second in 2023 — a single protocol quirk, not a bug in any one server, drove the largest DDoS ever disclosed.
Valgrind's Memcheck catches use-after-free, leaks, and buffer overruns in unmodified C binaries — at the cost of running your program 10-50x slower.
SpotBugs scans compiled .class files for 400+ bug patterns; Semgrep parses source directly. Neither alone would have caught CVE-2015-7501 fast enough.
