The short version
Updated August 2026
- Fingerprint focuses on the fingerprint layer and includes device and network signals as an API.
- The layers above that must still be built by you: a unified user view, email and phone intelligence, rules, and challenges.
- Rupt is a full fraud engine. It includes fingerprinting, email and phone intelligence, a rules engine, hosted challenges, and an AI agent that investigates accounts and monitors for new patterns.
- Both start at $99 a month for 20,000 calls. The difference is how much of the stack is included in that number.

Why choose Rupt.
A full fraud engine, end to end
Identification, intelligence, decisioning, and enforcement are one product, not four you wire together. One evaluation returns the fingerprint, the signals, the scored risks, and a verdict, and Rupt acts on that verdict. Nothing in the middle is left for you to build and then maintain.
100ms at p99
Not an average that hides a long tail. 99 out of 100 evaluations come back inside 100ms, which is what lets you put Rupt directly in the login and signup path instead of running it after the fact.
Risks you can actually build
Rupt ships with its own risks ready to go, and you can compose your own from individual indicators with your own weights and your own actions. That is real customization, not tuning a threshold on somebody else's score.
Unmatched support
Integration setup help, developer meetings, and direct Slack and email access, with replies in hours, on every plan. Most vendors reserve that for their top tier. Don't take our word for it though, just ask our customers.
State of the art AI
The agent protects and detects. It watches your traffic for new and emerging fraud patterns as they form, then tells you what it found and what to do about it, down to the policy changes and updates it recommends you make.
A challenge engine that's a whole journey
Not a single screen bolted onto a verdict. Challenges are customizable and built around an end goal, whether that's adding friction, converting a sharer into their own account, or stopping a takeover, with cooldowns and velocity controls shaping how and when someone gets challenged.
Single-vendor pricing
Fingerprinting, email and phone intelligence, rules, and challenges usually mean a vendor and an invoice each. Because Rupt ships them together, the bundle costs less than the sum of the point tools.
Migrating from Fingerprint.
- 01
Swap the client snippet. Load the Rupt SDK and call evaluate() on login, signup, and the actions you care about. Data starts flowing the same day.
- 02
Read evaluations server-side. One GET request returns the verdict, risks, fingerprint, and device ID where you used to read the visitor ID.
- 03
Run both vendors for two to four weeks. Visitor IDs don't map one to one to device IDs, so let returning users fill in the mapping before you cut over.
- 04
Turn on policies in observe mode, watch the verdicts against real traffic, then enforce. Challenges and blocks only fire once you say so.
