The 4 Pillars of API Security
A practical strategy for securing APIs in 2025. As APIs become the core of every digital business, and the leading criminal attack vector, the "AI will save you" promise of real-time, block-and-stop runtime defense has fallen short. This white paper, written by Mark Boyd and published by apidays with a foreword by Corey J. Ball (author of Hacking APIs), lays out a four-pillar approach (Discovery, Posture Management & ASPM, Testing with Context, and Observability & Runtime) that any organization can maintain in about 30 minutes a week. Download it for the full strategy, checklist, and a realistic look at where AI actually fits in API security.

- The four pillars of a modern API security strategy and how each maps to a specific business driver, from record API growth and ecosystem complexity to GenAI-enabled attacks.
- The 30-minutes-a-week approach to discovering shadow and zombie APIs, hardening posture, testing with context (SAST, DAST, BOLA, IDOR, SSRF), and monitoring at runtime.
- Where AI truly fits, and why signature-and-AI-only runtime defenses fall short, plus a real Data Theorem case of shadow APIs found on an unapproved cloud via app reverse engineering.
- OWASP API Top 10 (BOLA cited as the top API risk)
- Threat intelligence feeds / watchlists (used to verify bad actors and SDK/IP risk)
