Nearly $13 billion — that’s how much account takeover (ATO) fraud cost businesses in 2023 alone. This isn’t just another alarming stat — it’s a wake-up call for any organization managing user accounts. Industries like e-commerce and financial services are feeling the heat, with ATO attack rates spiking 36% and 10% year-over-year, respectively.
The methods behind these attacks aren’t new: stolen credentials from data breaches, phishing attacks, and malware are still the go-to tools for fraudsters. What is new? The scale, sophistication, and speed of these attacks. And traditional defenses—CAPTCHA, static rules, even MFA—aren’t enough on their own.
