FinanceGuard
Fintech · Series B
Challenge
$2.3M annual fraud losses from account takeover attacks. Existing WAF rules caught less than 40% of sophisticated ATO attempts, and manual review was not scaling.
Solution
Deployed Device Identification and Bot Detection across login and payment flows. Device Identification flags returning devices even after cookie clearing, while Bot Detection intercepts automated credential testing at the edge.
“We went from reviewing 200 fraud alerts per day to under 40. The false positive rate dropped to zero on legitimate users — our support team noticed before we did.”
— VP of Engineering, FinanceGuard
DataStack
SaaS · Enterprise
Challenge
Credential stuffing attacks averaging 50K+ attempts per day were bypassing their existing WAF. Attack traffic was consuming infrastructure resources and degrading performance for real users.
Solution
Bot Detection deployed at the edge to intercept automated traffic before it hits application servers. Smart Signals added for server-side session analysis to catch sophisticated bots that mimic human behavior.
“We were spending $18K/month on infrastructure just to serve bot traffic. Bot Detection cut that by 40% in the first week.”

CloudMetrics
Analytics Platform · Growth
Challenge
Migrating from FingerprintJS Pro with concerns about accuracy regression during the transition. Needed to validate accuracy parity before committing to the switch.
Solution
Full migration to Device Identification with 30 days of parallel running against FingerprintJS Pro. Side-by-side comparison dashboard tracked accuracy, latency, and identification stability.
“We ran both systems in parallel for a full month. Device Identification matched or beat FingerprintJS Pro on every metric we tracked. The migration was a no-brainer.”
