Fraud protection without a fraud team
Sift is a deep, network-trained platform for payment fraud, account takeover and abuse, built for companies with fraud teams. If you're a small team with forms that attract pitches, fake sign-ups and card testers, Doorman gets you most of the way today, without a sales call.
Free for 1,000 checks a month. Paid plans from $12. No card required.
Example: Doorman screening sign-ups and checkout, each judged in under half a second and delivered or kept out with the reason.
Sound familiar?
A demo before anything
No published pricing or self-serve plan; it starts with a sales conversation.
A full event integration
The JavaScript snippet, SDKs and events across the customer journey add up to a project.
Built for payments
Contact and demo forms full of pitches aren't what a payments platform is for.

const r = await doorman.check({
kind: "checkout",
email: order.email,
order: { items: "5× Gift card $100", total_usd: 500 },
signals: { card_country: "US", ip_country: "NG", attempts: 4, account_age_days: 0 },

Every decision comes from Doorman's models reading the submission, in milliseconds, with the reason attached.
Labelled test set: 104 invented but labelled contact-form and checkout submissions, judged live; latency is the median of those checks. Questions were not tuned to the set.
Questions
Is Doorman a replacement for Sift?
For forms and small-store checkout screening, often yes. For large-scale payment fraud and account takeover with a fraud team, Sift is the deeper tool.
Does Doorman see card numbers?
No. You send signals you already have, such as attempts and card and IP country. No card data is sent.
How fast is it?
About 160 ms median to judge a submission, inline, before you capture the order.
How much does it cost?
Free for 1,000 checks a month. Pro is $12 a month for 25,000 and Business is $49 a month for 250,000. Every plan gets the same models. See pricing.
