The short version
Updated August 2026
- Cloudflare protects the network edge: bot scores, JA4 fingerprints, WAF rules, and managed challenges applied to traffic before it reaches your app.
- It sees requests, not accounts. Email and phone intelligence, account sharing and takeover detection, and OTP challenges are outside its scope, so account fraud still reaches your application.
- 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.
- The two stack. Plenty of teams run Cloudflare in front of everything and Rupt at the application layer, where accounts live.

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.
Using Rupt with Cloudflare.
This one isn't a migration. The common setup is both, each at its own layer.
- 01
Keep Cloudflare doing what it does: proxy, WAF, and bot filtering at the edge. Nothing about Rupt changes that.
- 02
Load the Rupt SDK and call evaluate() on signups, logins, and sensitive actions. Rupt reads real client IPs correctly behind Cloudflare's proxy.
- 03
Turn on policies in observe mode and watch what the edge lets through: shared accounts, fake signups, and takeover attempts from real browsers.
- 04
Enforce. Risky logins get a hosted email or SMS challenge, abusive accounts get blocked, and everything is attributable to a device and an account, not just an IP.
