Real-time email reputation scoring. Stop disposable addresses, breached accounts, and synthetic identities at the front door — before they ever touch your ID verification flow.
Document checks and biometrics are powerful — but expensive to run. And they happen too late. By the time a bot or fraudster reaches the ID upload screen, you've already spent on compute, API calls, and manual review queues.
Most bad actors arrive with a red flag you can see instantly: a disposable address, a breached domain, or an email registered two hours ago. ProntoSignal catches them before they cost you anything.
Every email is analysed across six independent vectors. The composite score drives your onboarding logic — fast-track, friction, or block.
Is the address from a known disposable, temporary, or throwaway provider? We maintain a continuously updated registry of 10,000+ disposable domains.
A live, non-intrusive handshake with the destination mail server confirms the mailbox actually exists — without sending a single email.
Cross-references the address against 12B+ credentials from major public breaches. A total absence of breach history on a "years-old" email is itself a signal.
Does the email resolve to any public professional or social presence? A connected footprint raises confidence; a ghost profile lowers it.
Is the sending domain or its upstream IP on active spam, malware, or scam blacklists? Ongoing abuse patterns surface here in near real-time.
How old is the domain? Does it have healthy MX, SPF, and DMARC records? A 3-hour-old domain without proper mail setup is a near-certain fraud signal.
ProntoSignal is the outer wall. ProntoID's document and biometric checks are the inner sanctum. Use them together to build a risk-based onboarding funnel that's fast for legit users and impenetrable for everyone else.
At the very first touchpoint — signup form, checkout, age gate — the email is submitted. No UI delay, no extra screen.
A single API call returns a 0–100 trust score with itemised signal breakdown. Typical round trip: 312ms. Your UX never feels it.
Score ≥ 80: fast-track. Score 40–79: step up to biometric. Score < 40: block or queue for manual review. Your rules, our signal.
