Problem

Broken Access Control consistently ranks among the top application risks (OWASP Top 10). Sentinel Flow targets the gap between documented access rules and observed behavior—including IDOR and broader privilege failures, not only “RBAC documentation drift.”

The Problem

Organizations struggle to:

• Detect unauthorized access in real time — Logs and audits often lag, lack context, or need heavy manual triage
• Keep access models accurate — Which roles may call which endpoints is hard to document, version, and keep aligned with production
• Catch IDOR and horizontal abuse — Same-role users accessing each other’s resources routinely bypass coarse RBAC checks
• Spot privilege bugs early — Miswired authorization, missing checks, or inconsistent enforcement surface only after exploitation or expensive reviews

Many tools are costly, invasive, or demand exhaustive upfront policy authoring that teams cannot maintain.

Sentinel Flow's Approach

Sentinel Flow uses behavior-based learning:

• It observes legitimate traffic and infers which roles typically use which endpoints (vertical / role-to-route expectations, reflected as vertical_idor when violated)
• It supports detecting horizontal patterns where access should be scoped to a user or resource and crosses that boundary (horizontal IDOR)
• When a request is inconsistent with learned norms, it is flagged for review with less manual rule curation

That yields continuous BAC signal with lower operational overhead than hand-maintained rule sets alone.
