About Jscrambler
Jscrambler is the leader in Client-Side Security for the modern, composable web.
As organizations increasingly build digital experiences through third-party software supply chains and AI-powered agents, sensitive data is now created directly in the browser — the point of creation for digital interactions — making it one of the enterprise’s most privileged yet least governed attack surfaces.
Jscrambler’s Client-Side Security Platform is powered by a Behavioral Enforcement Core that governs how application code, third-party scripts, and sensitive data behave at runtime. By enforcing software integrity and data governance directly in the browser, the platform ensures sensitive data and AI inputs are controlled according to enterprise policy at the point of creation — before they leave the client environment.
Trusted by leading global retailers, airlines, financial services providers, and healthcare organizations, Jscrambler provides the visibility and enforcement organizations need to stop client-side attacks, prevent data leakage, and maintain compliance with regulations including PCI DSS, GDPR, HIPAA, CIPA, CCPA, and the EU AI Act.

Jscrambler Product Features
Application Security
Application security doesn’t end when code passes the pipeline. Modern applications execute in the browser, where proprietary logic is exposed, third-party components can change after deployment, and AI can accelerate reverse engineering, exploitation, and data abuse. Jscrambler extends your AppSec stack beyond build-time scanning and testing into the browser runtime—providing continuous protection and enforcement where applications actually execute. LLM-Resilient Code Protection hardens first-party application logic, including AI-generated and vibe-coded code, against reverse engineering, tampering, and AI-assisted attacks. Software Supply Chain Security discovers and controls first-, third-, and fourth-party components, detecting behavioral drift and blocking unauthorized data access or transmission at runtime. For AppSec, Dev, and Third-Party Risk teams, Jscrambler closes the client-side control gap with a runtime security layer that complements your existing app security stack.
Application Shielding
Applications are increasingly exposed to attackers who can inspect, reverse-engineer, and manipulate code directly in the browser. AI makes that process faster, automating code analysis and helping attackers identify vulnerabilities, extract proprietary logic, and bypass defenses. Jscrambler shields applications by transforming and hardening client-side code so it is significantly more difficult to understand, modify, or weaponize. Runtime protections detect and respond to tampering, debugging, code poisoning, and unauthorized manipulation, while uniquely protected builds prevent attackers from relying on one successful analysis across deployments. Protect proprietary logic, sensitive application functionality, and AI-generated code from the moment it reaches the browser—extending application security beyond the build pipeline to where your code is actually exposed.
Client-Side Protection
The browser is where modern applications execute—and where attackers can see, manipulate, and exploit the code, data, and third-party components behind digital experiences. Jscrambler provides a client-side protection layer that secures applications at runtime, protecting proprietary code, sensitive data, and critical functionality from reverse engineering, tampering, supply chain attacks, and unauthorized data collection. AI-generated code and AI-powered tools make exposed client-side logic easier to analyze and weaponize, while third-party scripts can introduce risk long after deployment. Jscrambler continuously protects and enforces application behavior in the browser, complementing AppSec, DevSecOps, and data security controls that stop at the server or build pipeline. Extend security to the browser—and protect your application where it is actually exposed.
Data Privacy Management
Jscrambler closes the critical gap between what users consent to and what actually happens to their data in the browser. Consent Management Platforms (CMPs) record user choices, but consent alone does not prevent third-party scripts, pixels, session replay tools, or AI-powered agents from accessing and transmitting sensitive information at runtime. Jscrambler provides a fine-grained enforcement layer in the browser, controlling which scripts can access specific data and where that data can go. This helps organizations address CIPA and wiretapping risk, CCPA/CPRA requirements, HIPAA protections for PHI, and broader privacy obligations through continuous visibility and enforcement. Jscrambler detects behavioral drift, blocks unauthorized data access and exfiltration, and governs AI-powered data collection. Go beyond consent management with technical enforcement where data is created.
PCI Compliance
Jscrambler provides a cost-effective, comprehensive approach to PCI DSS v4.0.1 compliance for modern web applications, with fine-grained control over the scripts, data, and behavior running in the browser. Rather than relying solely on Content Security Policy or broad script allowlisting, Jscrambler provides runtime visibility, behavioral enforcement, script authorization, integrity protection, sensitive-data controls, and continuous monitoring to help organizations meet requirements for managing payment-page scripts and preventing unauthorized access or e-skimming. Jscrambler’s deep client-side security expertise helps organizations address complex PCI requirements while reducing operational overhead and avoiding unnecessary controls that can disrupt digital experiences. Critically, Jscrambler is not limited to PCI compliance: the same platform extends protection to software supply-chain risk, first-party code, AI-generated code, AI agents, data governance, privacy, fraud, and runtime
Runtime Application Self-Protection (RASP)
Modern applications execute in environments attackers can inspect, manipulate, and automate. AI has accelerated that risk, giving attackers and free AI-powered tools the ability to analyze, reverse-engineer, and weaponize exposed application logic at scale. Jscrambler makes client-side applications self-defending by combining resilient code protection with active runtime defenses. Proprietary business logic, authentication flows, algorithms, and AI-generated code are hardened against AI-assisted analysis, while runtime protections detect and respond to tampering, debugging, code poisoning, and unauthorized manipulation. Each build is uniquely protected, raising the cost of automated reverse engineering and preventing exposed code from becoming an attacker’s roadmap. Extend application protection into the code itself—so applications can resist and respond to attacks where they execute.
Security Compliance
Compliance shouldn’t be a checkbox exercise. Its purpose is to reduce business risk—and that requires enforcing controls, not simply documenting policies or capturing consent. Jscrambler brings compliance into the browser runtime, where sensitive data is created, accessed, and transmitted, providing continuous visibility and technical enforcement across PCI DSS v4, GDPR, CCPA, HIPAA, the EU AI Act, and more. Unlike CMPs and consent platforms that record what users allow, Jscrambler enforces what scripts can actually access and transmit. This is critical as third-party code, AI-powered applications, and client-side data collection create risks that traditional controls can’t see—and as CIPA wiretapping litigation scrutinizes unauthorized data collection. Jscrambler detects behavioral drift, controls data access, blocks unauthorized transmission, and provides evidence of enforcement. Turn compliance requirements into controls that actively reduce risk.

JavaScript Obfuscators
JavaScript obfuscation can make code harder to read—but basic and free obfuscators are increasingly inadequate against modern reverse engineering and AI-assisted analysis. Attackers can use LLMs and automated tools to deobfuscate code, identify application logic, and uncover vulnerabilities at scale. Jscrambler goes beyond traditional obfuscation with resilient code protection designed to withstand AI-assisted analysis, combining multiple transformation techniques with runtime defenses against tampering, debugging, and manipulation. Each build is uniquely protected, making automated analysis harder and preventing attackers from easily applying reverse-engineering insights across deployments. Protect proprietary JavaScript, business logic, and AI-generated code against the next generation of reverse engineering—not just casual code inspection.
Reverse Engineering
Reverse engineering has become faster and more scalable with AI. Attackers can use LLMs and free AI-powered tools to analyze exposed application code, uncover proprietary logic, identify vulnerabilities, and turn client-side code into an attacker’s roadmap. Jscrambler makes applications resilient to this new reality by transforming and hardening code so it is significantly harder for humans and AI systems to understand, analyze, and manipulate. Each build is uniquely protected, disrupting automated analysis and preventing attackers from easily applying insights across deployments. Runtime defenses add another layer of protection by detecting tampering, debugging, and unauthorized manipulation as attacks occur. Protect the logic that makes your application valuable—before AI-assisted reverse engineering turns exposed code into an exploitable advantage.
