In one sentence: IPQualityScore (IPQS) is a broad fraud-detection platform; Veqen focuses on signup screening using email, IP, phone and domain signals. Neither a score nor a verdict proves a person's identity.
How they differ
| IPQualityScore | Veqen | |
|---|---|---|
| Scope | Wide fraud suite: IP, email, phone, device fingerprinting, transactions and more | Signup checks: email, IP, phone, domain |
| Device fingerprinting | Yes | No (server-side checks only) |
| Explanations | Scores, flags and reason fields, depending on endpoint and plan | Score, verdict, and a plain-English sentence per reason |
| Buying | See their site | Self-serve prepaid credits, 1,000 free per month |
When to choose IPQualityScore
If you need device fingerprinting, payment-fraud scoring or one vendor across many fraud surfaces, a broad suite makes sense.
When to choose Veqen
If you want to stop fake and throwaway signups with one server-side call, understand exactly why each one was flagged, and pay only for what you use, Veqen is simpler to adopt. It's also built to be called by AI agents through MCP.
Frequently asked questions
Does Veqen detect residential proxies?
Not reliably. Residential proxies route through real home connections. Email and phone signals can add context, but a combined signup check does not guarantee residential-proxy detection.
