📋 Decision Context

Question:

Should we add Cloudflare WAF, rate limiting, bot protection, and caching to our backend APIs?

Task: Cloudflare API security analysis for all backend services

🎯 Decision Made

Chosen:

Add WAF + rate limiting + bot protection via Cloudflare dashboard configuration for all 4 backend APIs (backend-api, backend-ai-api, backend-vitto-api, backend-docs-api), plus selective Cache-Control headers for public endpoints

Options Considered:

1. Keep current DNS-only proxy setup
2. Add WAF + rate limiting + bot protection (dashboard config)
3. Move to Cloudflare Workers API gateway
4. Implement Cloudflare Tunnel
5. Full Cloudflare API Shield (Enterprise)

💭 Reasoning

Current setup uses Cloudflare only as DNS proxy with SSL termination. No WAF, no rate limiting, no bot detection. CORS is not a security boundary — any non-browser client bypasses it. APIs are exposed to brute-force, OWASP attacks, and automated abuse. Cloudflare WAF managed rules + rate limiting + bot fight mode provides high security uplift with zero code changes (dashboard config only). Workers gateway rejected as over-engineering — NestJS apps with MongoDB can't decompose to edge functions. Cloudflare Tunnel rejected as premature — adds Dockerfile complexity for marginal gain at current scale. API Shield rejected — Enterprise tier, not justified yet.
