Threat and Risk Landscape

  • Broken object-level authorization and function-level authorization issues.
  • Weak authentication flows and insecure token handling patterns.
  • Excessive data exposure and insufficient input validation controls.
  • Abuse risk from missing rate limiting, anomaly controls, and API monitoring.

What The Service Includes

  • API threat modeling and trust-boundary mapping.
  • Authentication and authorization review across OAuth2, OIDC, and key-based flows.
  • Rate limiting, abuse prevention, and API gateway hardening recommendations.
  • Audit logging design and observability improvements for API events.

Who This Is For

  • Teams operating high-volume API ecosystems.
  • SaaS products exposing customer and partner APIs.
  • Enterprises modernizing API security posture and governance.

Delivery Process

  1. 1API inventory, classification, and risk-scoping workshop.
  2. 2Auth and authorization control testing and review.
  3. 3Abuse and resilience control evaluation including throttling and alerting.
  4. 4Remediation blueprint and verification strategy.

Real Business Use Cases

Public API hardening

Strengthen auth, authorization, and abuse controls for internet-facing API surfaces.

Internal service-to-service API security

Improve identity and policy controls for internal API communication paths.

Partner integration security review

Validate third-party integration controls and data exposure boundaries.

Security and Reliability

  • Controls aligned to both direct exploitation and API abuse patterns.
  • Design recommendations for scalable and maintainable API governance.
  • Evidence-backed findings with implementation-ready priorities.

Secure SDLC and Delivery Controls

  • API security requirements embedded in design and endpoint definition workflows.
  • Contract and security tests integrated into build and deployment pipelines.
  • Secrets and token handling controls enforced across environments.
  • Release checks for auth flows, rate limits, and logging completeness.

Reporting and Remediation Approach

  • Endpoint-level findings with risk context and exploitability notes.
  • Control-by-control remediation recommendations across auth, validation, and observability.
  • Developer-ready implementation actions mapped to API ownership.
  • Follow-up validation support to confirm control effectiveness.

Frequently Asked Questions

Do you review both REST and GraphQL APIs?

Yes. We evaluate API security risks across REST, GraphQL, and mixed integration models.

Can you help with OAuth and token security design?

Yes. We review and harden token lifecycles, scopes, claims, and authorization checks.

Do API security engagements include abuse and DDoS controls?

Yes. We include rate limiting, abuse prevention, and resilience design in scope where applicable.
