Use cases | Fraud and ATO prevention for merchants

Security without friction for merchant account opening and online access.

e-Commerce merchants today are under increasing pressure from persistent, often AI-powered fraud attacks and scams.

Some of the key challenges include:

Surges in fraud during
high-volume periods

Fraudulent actors look to exploit spikes in transactions to open fraudulent accounts or take over existing ones. Sign-up attacks are reported to have spiked ~309% during a recent holiday season.

Chargebacks and
“friendly fraud”

Chargebacks are a costly consequence, not only from unauthorized transactions but also from buyer’s remorse or post-holiday budget strain. Many customers bypass the merchant entirely and go straight to their bank.

The AI
arms race

While merchants are starting to use AI for fraud detection, fraudsters are rapidly advancing their use of AI (deepfakes, cloned identities, bot-attacks) to attempt to bypass defenses. Legacy tools are no longer sufficient.

Need for customer-friendly security

Too many security steps during account opening or login often lead to poor user experience. This causes potential customers to abandon shopping carts, drop out of registration flows, or churn. During peak shopping, even a small amount of friction can have a big impact on cost. One of the biggest risks to online revenue is losing customers because of friction.

Operational and reputational costs

Fraud doesn’t just cost in terms of lost goods or payments; there’s administrative burden, fraud investigation, dispute resolution, customer service time, potential bans by payment processors if chargeback thresholds are exceeded, card network compliance issues and most importantly, loss of customer trust.

It’s a tight rope for merchants to walk: prevent fraud, account takeover (ATO), and chargebacks, while also delivering fast, easy customer experiences. Luckily, help is at hand.

The solution: Secure account opening and online access,
without friction.

A layered, adaptive approach to risk intelligence, authentication, and fraud prevention enables merchants to significantly reduce online fraud and ATO risk while enriching the customer experience — regardless of if someone is new to an account or an existing accountholder.

Using our solution, merchants can:

Reduce account takeovers:

Prevent unauthorized access attempts, stop credential stuffing or bot attacks, protect existing customer accounts from being hijacked.

Lower chargebacks and friendly fraud:

By verifying true identity effectively and early, there is less unauthorized or disputed activity; also more defensible in dispute resolution with transaction signing providing proof of intent.

Improve authentication and authorization rates to fuel revenue growth:

Less friction means better conversion during account opening; allowing you to easily recognize legitimate customers, streamline their buying experience, improve checkout rates, and reduce abandonment and false declines.

Operational savings and reputation protection:

Fewer losses, reduced customer service overhead needed for fraud investigation, fewer issues with payment processor and card brand thresholds, higher customer trust.

Key capabilities and benefits.

Adaptive / risk-based authentication

Assess risk signals such as device, behavior, location, time, historical patterns at account opening and login. Escalate for challenge only if it exceeds risk parameters.

Users with low risk pass smoothly; high-risk events are caught with minimal customer impact. Reduces both false positives and fraud.

Behavioral analytics & device data

Determines behavioral anomalies, such as a customer's typical spending activity, as well as device and location inconsistencies that may be indicative of fraud.

Advice is given on the associated risk and allows for a step-up challenge to prevent fraud but allow legitimate transactions.

Strong MFA / progressive factor escalation

Based on context, such as first-time login, new device, elevated transaction, progressively requires stronger authentication like push notifications, biometrics, etc.

Enhances security only when needed; avoids burdening all users with heavy verification.

Real-time fraud signals and velocity indicators

Real-time indication of abnormal volumes associated with a device or location to flag potential fraud when creating an account.

Captures suspicious behaviors; enables early detection and prevention before chargebacks or account losses.

Seamless UX / invisible challenges where possible

Hides most checks “under the hood”; requires a visible challenge only where risk is high. Silent authenticators include browser and device ID, or smart caching of trusted devices.

Maintains fast account opening and login flows, reduces cart abandonment or drop-off in registration.

Sample customer journey flows.

User begins to create an account. Entersekt’s system monitors for risk signals (IP reputation, time, device anomaly, velocity signals).
If low risk: allow account creation with standard validation (email, password).
If medium/high risk: challenge with MFA (OTP or push or biometric)

Why merchants choose Entersekt.
