Why payment teams choose the Security plan

The Security plan's fraud score (0–99) mirrors Stripe Radar's risk scale, letting you set threshold-based rules without additional mapping. Datacenter, AI-crawler and residential proxy flags surface the full risk context in a single API call — no secondary database join needed at checkout latency.

From prototype to production

Start on the free plan, upgrade when you hit limits. Security plan includes a 7-day trial — no credit card for free tier.
