Comprehensive fraud prevention

Account takeover (ATO) continues to be a growing problem for web & mobile app businesses

ATO fraud is getting more sophisticated, with fraudsters rapidly evolving their tactics. ATO attacks increased 307% between 2019 and 2021, with losses totaling $11.4B in 2021.

ATO is fueled by the increase in daily massive data breaches, social engineering, phishing, and brute force attacks. Hackers gain access to personally identifiable information (PII), which leaves consumer accounts vulnerable to takeover.

The threat of ATO is more prevalent than ever, and will result in loss of business if not kept top of mind when building out your fraud prevention technology stack.

ATO attacks can result in:

  • Identity theft
  • Revenue loss and costly chargebacks
  • Reduced customer engagement
  • Brand damage and clean-up costs
  • User abandonment
