# API Security Guides

Protect APIs from abusive traffic, authorization failures, and unsafe integrations at the edge.

- [API Protection at the Edge](/en/guides/api-protection-edge.md): Configure provider-neutral API protection at the edge with an inventory, strong authentication, schema validation, quotas, logging, and safe rollout.

- [Zero Trust Web Apps](/en/guides/zero-trust-web-applications.md): Learn how to apply zero trust to web applications with a practical sequence for identity, resource policy, APIs, service-to-service access, and validation.

- [DDoS Protection Guide](/en/guides/ddos-protection.md): Understand DDoS protection layers, origin security, traffic controls, observability, and the response preparation required before an attack.

- [Rate Limiting Guide](/en/guides/rate-limiting.md): A practical, provider-neutral guide to rate limiting APIs and web flows by identity, route, and risk without punishing legitimate customers.

- [Secure Webhooks](/en/guides/secure-webhooks.md): A practical guide to secure webhooks: webhook signature verification, webhook replay protection, idempotency, secret rotation, schemas, and safe incident handling.

- [Account Takeover Defense](/en/guides/account-takeover-defense-edge.md): Build layered account takeover defenses across the edge, identity, application, and fraud stack without turning legitimate customers into false positives.

- [Preventing BOLA in APIs](/en/guides/preventing-bola-authorization-failures-apis.md): Prevent broken object level authorization and cross-tenant API exposure with object checks, tenant-scoped data access, adversarial tests, logging, and incident response.

- [Reliable API Design](/en/guides/reliable-api-design.md): A practical guide to reliable API design: explicit contracts, deadlines, API idempotency, safe caching, API rate limiting, queues, observability, and protected origins.
