TL;DR: APIs account for more than 71% of web traffic, 84% of organisations have experienced an API security incident, and AI agents are now consuming APIs at machine scale, according to LEVO. The result is a broader attack surface where authorization failures, unsafe consumption, and inventory gaps turn API security into a governance problem, not just an engineering one.
Editorial analysis by NHI Mgmt Group, based on content published by LEVO: “The Ultimate Guide to OWASP API Security Top 10 (2023): Definitions, Examples, Mitigations & Enterprise Strategies”.
By the numbers:
- APIs accounted for more than 71% of all web traffic in 2024.
- 84% of organisations experienced an API security incident.
- The average global cost of a single data breach is now 4.88 million dollars.
Key questions
Q: What breaks when API authorization only checks the logged-in user, not the object being accessed?
A: Broken object-level authorization creates a gap where an authenticated caller can still reach records, properties, or functions it should never see.
Q: Why do API security failures create business and regulatory risk so quickly?
A: API failures can expose customer data, payment flows, and partner integrations in a single control path, which means one weak endpoint can trigger privacy, fraud, and continuity consequences at the same time.
Q: What do teams get wrong about API inventories and documentation?
A: Teams often treat documentation and inventories as proof that an API estate is complete.
Practitioner guidance
- Implement object-level authorisation everywhere Check every API request against the specific object, tenant, or record being accessed, not just the caller's general session or role.
- Build a live API inventory Track internal, external, partner, and deprecated endpoints with ownership, version, and retirement status so shadow APIs are not left outside governance.
- Harden authentication for machine consumers Use short-lived tokens, strong credential rotation, and step-up checks where workload or agent behaviour creates higher risk than human use.
Bottom line: API risk is now dominated by valid-request abuse, where authenticated callers exploit object scoping, business logic, and inventory gaps instead of classic payload attacks.

API security has become identity governance for digital services. The article is right to frame APIs as business infrastructure, but the deeper governance point is that API calls now carry identity, entitlement, and context risk together. That means IAM, PAM, and application security can no longer work in silos when workload and human access converge on the same interfaces. Practitioners should treat API authorisation as a governed access model, not a point control.
A few things that frame the scale:
- 71% of organizations use third-party APIs, according to Gartner’s 2024 data.
A question worth separating out:
Q: How should organisations govern AI agents that need database access?
A: Organisations should give AI agents narrow read access by default, separate write privileges from query privileges, and require human approval for any session that can modify data. That keeps agent activity inside a clearly bounded role while preserving auditability and reducing the chance of unsupervised state change.
