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. 41 Ratings Visit Website Passwork Passwork is a password manager built for security-conscious organizations, available as both a self-hosted (on-premise) solution and a secure cloud service.

About Blazor lets you build interactive web UIs using C# instead of JavaScript. Blazor apps are composed of reusable web UI components implemented using C#, HTML, and CSS. Both client and server code is written in C#, allowing you to share code and libraries. Blazor is a feature of ASP.NET, the popular web development framework that extends the .NET developer platform with tools and libraries for building web apps. Blazor can run your client-side C# code directly in the browser, using WebAssembly. Because it's real .NET running on WebAssembly, you can re-use code and libraries from server-side parts of your application. Alternatively, Blazor can run your client logic on the server. Client UI events are sent back to the server using SignalR - a real-time messaging framework. Once execution completes, the required UI changes are sent to the client and merged into the DOM.	About WebAssembly (abbreviated Wasm) is a binary instruction format for a stack-based virtual machine. Wasm is designed as a portable compilation target for programming languages, enabling deployment on the web for client and server applications. The Wasm stack machine is designed to be encoded in a size- and load-time-efficient binary format. WebAssembly aims to execute at native speed by taking advantage of common hardware capabilities available on a wide range of platforms. WebAssembly describes a memory-safe, sandboxed execution environment that may even be implemented inside existing JavaScript virtual machines. When embedded in the web, WebAssembly will enforce the same-origin and permissions security policies of the browser. WebAssembly is designed to be pretty-printed in a textual format for debugging, testing, experimenting, optimizing, learning, teaching, and writing programs by hand. The textual format will be used when viewing the source of Wasm modules on the web.
