Stop Takeovers at Login, Not After the Damage.

The problem

Breach dumps hand fraudsters millions of valid logins. Credential stuffing turns them into drained accounts at machine speed.

1. 01Stuffing at Scale. Automated login bursts test stolen credentials across thousands of accounts — too fast and distributed for rate limits alone.
2. 02Trusted-Session Abuse. Once inside, takeover artists look exactly like the customer: same account, same history, new intent.
3. 03Payout Diversion. Changed emails, new devices and fresh payees precede the cash-out — each harmless-looking on its own.
4. 04Support Social Engineering. Locked-out fraudsters pressure help desks into resets. Without device context, agents guess.

The solution

Ambriel scores every login against device, behavior and breach context — genuine users pass untouched, takeovers stop cold.

1. 01Device Fingerprinting. Unknown devices, emulators and network mismatches flag logins the password alone would approve.
2. 02Behavioral Baselines. Login rhythm, navigation and session patterns build a per-user normal — deviations raise the score instantly.
3. 03Breach-Aware Screening. Emails and credentials appearing in breach dumps trigger stricter checks before access is granted.
4. 04Step-Up on Risk. High-risk logins route to review or extra verification instead of a binary allow-or-block.
