Case Study: Flutter cuts credential-stuffing by up to 90% and saves £2M+ annually with Cloudflare Bot Management

Flutter - Customer Case Study

Flutter Entertainment, the technology-driven holding company behind Paddy Power and Betfair, handles large volumes of customer transactions and sensitive personal data. The company suffered an extensive credential-stuffing attack that caused 70–90% of its traffic to be classified as malicious, creating significant financial and operational risk.

By deploying Cloudflare Bot Management and using its Bot Score, Flutter reduced malicious traffic in some situations by up to 90%, saving an estimated £2 million+ per year and restoring visibility and control over visitors. Cloudflare’s technically skilled team provided hands-on support to debug complex issues, delivering a fast, cost-effective security upgrade.
