The challenge

Fraud patterns that cost Fintech businesses the most

Account takeover attacks

Credential-stuffing bots cycle through millions of leaked passwords, silently compromising accounts and initiating fraudulent transfers.

Synthetic identity fraud

Fabricated identities pass KYC with real-looking data, then abuse credit lines, initiate chargebacks, or launder funds before disappearing.

Money mule onboarding

Mule accounts are created using VPNs, disposable emails, and residential proxies — designed to blend in with legitimate customers during onboarding.

Regulatory & compliance exposure

Undetected fraud events create AML exposure, trigger regulatory audits, and generate mandatory incident reports — all with real cost.

How it works

One API call. One decision. No extra vendor.

1

Send the context you have

Pass the IP, email, and user-agent from the login request — no extra data collection needed.

2

Get allow, challenge, or block

RequestGuard combines IP reputation, email signals, proxy detection, and device fingerprints into one structured decision.

3

Act in your app

Let low-risk sessions through, show a CAPTCHA on challenge, or block high-risk requests — with full audit trail in your dashboard.

Capabilities

Purpose-built signals for Fintech

01.

High-risk IP signals

Detect Tor exit nodes, datacenter IPs, residential proxies, and known fraud-associated ASNs at login and onboarding.

02.

Velocity & pattern detection

Identify credential-stuffing by correlating request velocity, ASN clustering, and user-agent diversity across login attempts.

03.

Onboarding risk scoring

Score new account applications with email risk, IP reputation, and domain signals to flag synthetic identities before they're activated.

04.

Explainable decisions

Every decision comes with structured risk factors your compliance team can read — ready for audit trails and regulatory reporting.

Integration

Two lines of code. Full fraud coverage.

Send the context you already collect. Get back a structured decision with risk factors — ready to act on without a separate lookup per signal.
