AWS API Gateway Security Testing

AWS API Gateway security testing evaluates whether the APIs exposed through your gateway can be abused to access data, invoke backend services, bypass authorization, or exhaust resources. Vynox Security manually tests authentication, authorization, token handling, request validation, rate limits, error responses, data exposure, and relevant AWS configuration paths. The result is a verified, prioritized view of exploitable risk rather than a scan-only output.

A penetration test is particularly valuable when AWS API Gateway exposes customer data, business functions, partner integrations, or services used by AI applications. Configuration controls alone cannot prove that object-level authorization, tokens, request transformations, and backend integrations resist attacker behavior. Manual testing helps identify exploitable gaps before a public launch, customer security review, or audit evidence request.

Testing covers the OWASP API Top 10, with emphasis on broken object-level authorization, broken authentication, excessive data exposure, mass assignment, injection, unsafe consumption of downstream APIs, rate-limit evasion, and resource exhaustion. Vynox also examines how API routes interact with AWS IAM permissions, backend integrations, secrets, logging, public exposure, and cloud storage to identify realistic attack chains.

API Security Testing typically takes 3–5 business days for a scope of up to 20 endpoints. The timeline can expand when an API has complex role models, many tenant boundaries, GraphQL operations, numerous integrations, or high-risk workflows. Before testing begins, Vynox scopes endpoints, environments, accounts, and guardrails so the assessment targets the most meaningful risks without disrupting production operations.

Testing is designed to validate security safely and is performed within agreed rules of engagement. Vynox coordinates target environments, approved testing windows, rate limits, test accounts, and any sensitive actions before work starts. Destructive or high-impact scenarios are restricted to staging or sandbox environments where appropriate. Confirmed production risks are documented with sufficient evidence while avoiding unnecessary service disruption.

You receive a technical report with confirmed findings, affected endpoints or components, HTTP-level evidence, reproduction steps, CVSS severity scoring, and developer-ready remediation guidance. Vynox also provides an executive summary for leadership. Findings can be mapped to SOC 2 and ISO 27001 evidence requirements, helping teams use the assessment in customer questionnaires and compliance preparation.

Yes. APIs that feed LLMs, RAG pipelines, or autonomous agents deserve particular scrutiny because compromised inputs can expose data, poison model context, or become indirect prompt-injection channels. Vynox tests the API layer alongside relevant AI security risks, including access-control failures, sensitive data exposure, unsafe tool access, and pathways that could influence downstream model or agent behavior.
