IPQualityScore (IPQS) is a fraud-prevention platform: risk scoring across IP addresses, devices, phone numbers, email addresses and more. If you need a fraud score that combines many signals in one place, a platform like that is built for it.
isBusinessEmail is narrower on purpose. It classifies the email domain for B2B products: work or personal, disposable, relay, blocked, and whether the company runs Google Workspace or Microsoft 365.
Different scopes

Choose a fraud platform when…
- Fraud is costly enough to justify combined IP, device and payment signals.
- You need one score that blends many inputs.
Choose isBusinessEmail when…
- The question is “is this a company?”, not “is this person a fraudster?”
- You need onboarding and sales routing by Google Workspace or Microsoft 365.
- You want a free, explainable, privacy-conscious check.
Combining them
Many teams use a dedicated work-email check at signup and a fraud platform on payment or high-risk actions. isBusinessEmail’s is_disposable, is_new_domain, is_lookalike and is_blocked flags make good inputs to whatever fraud scoring you already run. See Free trial abuse.
