Account takeover (ATO) prevention & protection

ATO occurs when malicious actors use stolen or leaked credentials to access user accounts. These attacks can lead to fraud, reputational damage, and lost customer trust. ATO is a common entry point for broader fraud activity. Once an attacker controls an account, they can steal personal data, drain loyalty points, place fraudulent orders, or move money across accounts. Blocking ATO attempts early helps prevent downstream fraud and financial losses.

DataDome uses advanced bot protection and behavioral analysis to detect and block automated login abuse in real time. We monitor signals like login velocity, behavioral anomalies, device fingerprinting, and IP reputation to stop ATOs before accounts are compromised. DataDome also detects suspicious post-login behavior such as rapid profile updates, changes to saved payment methods, and account linkages across shared IPs or devices. These signals provide additional context for security and fraud teams investigating coordinated attacks.  Learn more.

Yes. DataDome automatically detects and mitigates credential stuffing by analyzing login patterns, failed authentication rates, and infrastructure signals. Our Cyberfraud Protection Platform prevents large-scale ATO attempts without disrupting legitimate users.
