A Data-Driven Approach to ATO Prevention

The challenge of account takeover (ATO) and related fraud continues to impact many of the world’s most popular web applications. Session hijacking in particular has become the “path of least resistance” for attackers because it allows them to bypass authentication entirely, including multi-factor authentication (MFA).
Flare’s Account and Session Takeover Prevention tackles these challenges by collecting and maintaining a world-class dataset of leaked credentials and active session cookies. The following ROI calculator will provide you insights into the estimated number of end-user accounts exposed to session hijacking, broken down by industry.

Flare Account and Session Takeover Prevention (ASTP) ROI

Organizations can easily access and operationalize Flare Account and Session Takeover Prevention data via API, enabling them to create workflows to quickly, detect risky active sessions, proactively combat fraud, and strengthen the security of their users.

How much does a single account takeover cost your company?

If you don’t know the answer to this question, we recommend setting the default to $100 per account. For more information on how to estimate the cost of an account takeover to your business, see the appendix.

How many end users does your web application have?

Monthly active users (MAU) will yield the most precise results.

ATO FAQs

The cost of an ATO depends on your industry, fraud risk exposure, and the resources spent on investigations. On average, ATO incidents range from $50 to $200 per compromised account. For estimation purposes, we recommend using $100 per account as a baseline in the calculator.

This figure is based on new infected devices identified through Flare’s collection efforts—devices where infostealer malware successfully executed and extracted browser data in the previous month. Recently infected devices pose the highest risk, as they are more likely to contain active sessions vulnerable to hijacking.

Flare tracks over 100 widely used web applications, categorizing data by industry and sub-industry while anonymizing company names. To simplify calculations, we assume one exposed device equals one exposed account. While some devices contain multiple accounts, and some accounts appear across multiple infected devices, these variations tend to balance out, making this a reasonable estimate of ATO and session hijacking exposure.

“Estimated ROI” compares the annual ATO exposure cost with the cost of Flare’s Account and Session Takeover Prevention (ASTP) solution. The annual exposure cost is calculated by multiplying monthly exposure cost by 12, while ASTP costs are based on the number of end users in your web application.

This model assumes customers proactively mitigate risks by enforcing password resets and revoking active sessions for exposed accounts flagged by Flare, reducing the likelihood of exploitation.

Effective ATO prevention requires the ability to verify and invalidate session cookies. These capabilities are typically available in Customer Identity and Access Management (CIAM) systems.

Flare provides API documentation, SDKs, and engineering support to help ASTP customers integrate these controls seamlessly.
