Expanding Client-Side Execution Gaps Accelerate Modern Fraud Tactics
Fraudsters are increasingly exploiting client-side workflows, using bots to manipulate logic, bypass validation, and alter execution directly in the browser before backend systems can detect it. As traditional defenses rely on behavioral signals after the fact, this creates a critical gap at the point of execution, allowing attacks to scale undetected.
Many fraud defenses stop at the backend, leaving a blind spot where attacks occur: the browser. Jscrambler adds a layer of fraud detection at runtime, monitoring the integrity of authentication, user sessions, and client-side interactions, giving the security teams visibility into threats that would otherwise go unnoticed.
Account takeovers, payment fraud, pricing manipulation, and loyalty program abuse can happen in seconds, especially via bot-driven or AI-powered attacks. Jscrambler actively prevents these threats by monitoring user behavior, enforcing real-time workflow controls and data fencing, and complementing backend systems to block abuse before it reaches accounts or transactions.
Jscrambler integrates with your existing fraud and risk systems, such as Fraud Management Platforms, SIEMs, and risk engines, via APIs and connectors to monitor and protect booking flows, checkout, pricing, and transaction processes from abuse and manipulation.
Granular Third-Party Script Control
Jscrambler provides fine-grained control over how third-party tags are allowed to behave and what data they can access. The solution can scan and assess risk level for every third-party script on a website, allowing security teams to approve or block them accordingly.
Data Fencing
Jscrambler provides data fencing capabilities, which allow security teams to define exactly which data elements different third-party scripts are authorized to access or manipulate. This prevents data leakage and ensures compliance with data privacy regulations.
Polymorphic Obfuscation and Self-Healing Protection
Jscrambler employs advanced obfuscation techniques that transform the original JavaScript code into a functionally equivalent but unintelligible version. This prevents attackers from reverse engineering or tampering with the code. Additionally, Jscrambler supports self-healing, which automatically restores the code’s original functionality, even if parts of it have been modified by malicious actors.
Runtime Protection
Jscrambler provides dynamic runtime protection and code locks for first-party JavaScript code, ensuring that the code only runs in its intended environment and under specified conditions. Jscrambler can detect and prevent unauthorized code execution, debugging, emulation, and tampering attempts.
Code Locks
Jscrambler can lock code to specific domains, browsers, dates, or devices, and trigger custom actions or messages in response to security threats.
Real-Time Threat Monitoring and Alerting
Jscrambler monitors first-party and third-party tag behavior in real time, collecting and analyzing security telemetry from each browser session. Its advanced technology identifies and alerts security teams of any suspicious or malicious activity, such as code injection, data exfiltration, phishing, or skimming attacks. The solution also provides detailed reports and dashboards that enable security teams to visualize and investigate detected threats.
