Problem
Staffing and recruiting agencies rely on long-lived API keys to integrate third‑party vendors with their applicant tracking systems (ATS). These keys are often over‑scoped, lack expiration, and are not tied to contract terms, creating hidden risks of unauthorized data access, regulatory non‑compliance, and difficulty revoking access without disrupting operations.
Solution
Sentinel Layer provides a runtime API governance platform that sits between vendor integrations and the ATS, enforcing contract terms on every API call. It issues short‑lived, scoped tokens with field‑level policies, ensuring vendors can only perform the CRUD operations and access the data explicitly permitted in their statements of work. The platform evaluates policies inline with sub‑20 ms latency, automatically expires access when contracts end, and supports instant, isolated revocation without affecting other integrations. All API actions generate tamper‑evident cryptographic audit logs, giving agencies a built‑in compliance trail. By keeping real ATS credentials within the enterprise boundary, Sentinel Layer eliminates the need to expose long‑lived keys to vendors.
Target Audience
Primary customers are staffing and recruiting agencies that manage multiple third‑party vendor integrations with their applicant tracking systems and need to enforce data‑privacy, security, and regulatory requirements.
