Company

As applications became more composed, powered by third-party scripts and AI agents, the browser evolved from a display layer to an execution environment. But enterprise security architectures didn't evolve with it.

Jscrambler is the client-side security platform that extends enterprise security governance into browser execution, protecting applications and data where they're actually created, in real-time, with enforcement-based governance, not just detection.

Jscrambler: Pioneer and Leader in Client-Side Security

We started in 2010 to solve a crucial yet overlooked security problem. Client-side applications were (and still are) mostly exposed, leaving them vulnerable to compromise. Finding no winning and comprehensive solution, we created one and built a company around it.

Client-Side Security Leadership

Our Story

Jscrambler has been obsessed with browser runtime security for 15 years. We started as experts in protecting code. We evolved into experts in protecting data. Today, we're leading the industry in a new category: client-side security.

The market moved. Applications became composable, filled with third-party scripts, AI agents, and uncontrolled logic. Data stopped being created in backend systems and started being created in the browser. Security architectures didn't evolve with these shifts.

We did. Jscrambler extends enterprise security governance from infrastructure into browser runtime where applications execute, where data is created, and where AI agents operate. We provide visibility, enforcement, and compliance proof for the execution environment that traditional security architectures missed.

Our Vision

A world where enterprise security governance extends seamlessly from infrastructure to browser runtime—where applications execute with the same visibility, control, and compliance proof that organizations have achieved behind the edge. Where CISOs have unified governance across build, backend, perimeter, and now runtime. Where data is protected not just in transit and at rest, but at the point of creation. Where AI-powered scripts and threats are governed with the same rigor as traditional infrastructure risks.

Our Mission

To extend enterprise security governance into browser runtime, enabling organizations to protect their applications, data, and code at the point of creation—where they're assembled, accessed, and at risk. We do this by providing visibility into every script and AI agent, enforcement of policy at runtime, and proof of compliance for regulators.

One Solution For Every Team

CISO / ARCHITECT

Unify your security governance layer to fill priority risk gaps. Extend control from infrastructure through browser execution with integrated visibility and enforcement.

APPSEC / INFOSEC

Secure runtime beyond build. Defend against AI-powered threats while controlling third-party script behavior. Detect and block execution-time threats.

SECURITY ENGINEER

Stop sensitive data from being leaked and into GenAI. Enforce data access policies at the point of creation in browser execution.

TPRM

Govern vendor behavior and measure risk. Track third-party script activity, enforce boundaries, prevent unauthorized access.

DATA PRIVACY

Enforce consent and AI data governance at runtime. Prevent unauthorized data collection. Prove compliance with GDPR and privacy regulations.

SECOPS

Reduce alert fatigue while preventing new client-side threats. Runtime behavioral enforcement stops attacks before they happen, not after alerts.

DIGITAL / PRODUCT

Speed and security aren't opposites. Add third-party tools and AI with governance. Visibility into access, enforcement of boundaries, continuous compliance.

The browser is where modern applications execute. It's where sensitive data is created. It's where AI agents operate. And it's where your traditional security architecture ends.

Jscrambler extends enterprise security governance into browser execution—giving you visibility, enforcement, and compliance proof where it matters most.

Whether you're solving for compliance (PCI DSS v4, GDPR, EU AI Act), protecting customer trust (preventing unauthorized data collection), safeguarding competitive advantage (protecting pricing and strategy), or defending against threats (AI-powered script behavior, runtime exploits)—Jscrambler bridges the gap between your infrastructure security and your application execution environment.

Jscrambler serves enterprises across regulated industries—fintech, healthcare, retail, media—and high-growth companies that can't compromise on security. From Fortune 500 payment processors to innovative digital-first organizations, our customers trust us to extend their security governance where traditional edge controls end and browser execution begins.
