The fraud prevention industry has a dirty secret: most of the big-name platforms were architected in the mid-2010s, when bots used AWS and DigitalOcean IPs. That world no longer exists.
IPQualityScore (IPQS)
IPQS is the most widely deployed IP reputation API in the world, and also one of the most outdated when it comes to residential proxy detection. Their core database is built on static ASN and abuse history records. The moment a fraudster rotates to a fresh residential exit node, IPQS returns a clean score.
SEON
SEON's strength is social enrichment. This works for KYC verification but is largely useless for real-time bot detection. SEON does not perform client-side hardware fingerprinting, meaning it has no visibility into whether the browser connecting to your platform is headless.
The Sentinel Difference
Sentinel operates at the protocol and hardware layer, not the reputation layer. We look at how your user's device communicates, not just where it's connecting from. That distinction is the difference between catching 60% of fraud and catching 99.9% of it.
