Device fingerprint vs account risk API — pick the right job
Device IDs answer identity. Account risk APIs answer allow/deny. Here is how to choose — and when you need both.
By AbuseGraph Team
Two different questions
| Question | Typical product |
|---|---|
| Have we seen this browser before? | Device fingerprint / visitor ID |
| Should we allow this signup or login? | Account risk / abuse API |
Buyers often get a sticky ID and still have to invent verdicts. Or they buy a fraud suite when they only needed account decisions.
When a device ID is enough
- You already have a mature rules engine
- You only need clustering for analytics
- Payment fraud is out of scope and account policy lives elsewhere
When you need a risk API
- You want score + verdict + reasons at signup/signin
- You need lists, rules, and linked accounts in-product
- You want check-based pricing with a live free tier
AbuseGraph’s stance
We are an account-protection API. Device and TLS signals feed the score; the product you ship is the decision. Compare shapes on /comparison — not brand laundry lists.
