01 / DECISION

When this primitive earns a place

Keep proxied traffic on Cloudflare, hide direct origin paths, and reserve application rate controls for expensive operations.

02 / ARCHITECTURE

Build the smallest defensible path

Inventory exposed IPs and protocols, separate volumetric from application-layer scenarios, define degradation behavior, and rehearse escalation contacts.

  1. 01Name the contract

    Keep proxied traffic on Cloudflare, hide direct origin paths, and reserve application rate controls for expensive operations.

  2. 02Add one primitive

    Inventory exposed IPs and protocols, separate volumetric from application-layer scenarios, define degradation behavior, and rehearse escalation contacts.

  3. 03Capture failure evidence

    Verify no unintended origin exposure, monitor edge and origin traffic separately, and test controlled degradation without generating hostile traffic.

03 / REPRODUCE

Evidence before confidence

Verify no unintended origin exposure, monitor edge and origin traffic separately, and test controlled degradation without generating hostile traffic.

04 / BOUNDARY

The production boundary

DDoS protection cannot repair an origin reachable around the proxy or an endpoint whose normal request is intrinsically too expensive.

05 / FIRST-PARTY SOURCES

Keep first-party sources authoritative

Product behavior, limits, pricing, and availability can change. Re-check these sources before acting.
