Prevent Account Takeover (ATO)

An effective ATO prevention strategy decreases costs and increases revenue by stopping fraud without user friction.

Why Account Takeover (ATO) Prevention Matters

Billions of stolen credentials are available on the dark web. And, often, those credentials are weaponized prior to public disclosure. To compound the problem, continuous advances in attacker tools, techniques, and AI has resulted in increased ATO and fraud.

These attacks lead to the theft of financial information—draining bank accounts and loyalty points, enabling fraudulent purchases, or using your customers’ accounts to facilitate scams.

It’s crucial that you have an effective prevention strategy to mitigate the ripple effects of ATO across your business, from increased fraud costs to brand damage and even missed revenue opportunities.

How F5 Can Help

Attackers use automated credential stuffing attacks and manual impersonation to validate compromised data and account takeover to commit fraud.

Mitigation tools like CAPTCHA and multi-factor authentication (MFA) often fail to stop fraudsters and also frustrate real customers, leading to lost revenue and brand abandonment.

F5 monitors login attempts to digital accounts in real time and distinguishes between real users, bots and automation, and manual (human-driven) fraud attempts.

F5 can help you protect strategic business outcomes by providing an effective strategy for balancing fraud prevention and customer friction.
