YMC Secure Browser Check, developed by YMC Yazılım Teknolojileri Anonim Şirketi, is a Chrome extension that inspects a browser's exposure to common web threats. The tool runs client-side diagnostics to reveal IP leaks, fingerprinting vectors, insecure cookies, and missing security headers without sending data externally. It groups network- and application-level checks into a single diagnostic view. Privacy-conscious users, web developers, and security auditors who need a quick browser audit on desktop will find it useful.

It functions as a local diagnostic dashboard for browser security

The extension performs targeted audits of the current page and presents results in a compact dashboard. Checks include WebRTC leak detection, browser fingerprinting analysis, cookie security inspection, and HTTP security header audits. Results appear without external network calls because the extension executes tests locally, which preserves test data within the browser. The dashboard is designed for quick verification rather than continuous protection.

It maintains privacy by running tests entirely in the browser

The tool's local execution model means no diagnostic data is transmitted to outside servers, a behavior the developer documents. To inspect a site accurately the extension requires the browser permissions 'scripting' and 'activeTab', which enable page-specific analysis. Those permissions are necessary for the extension to read headers and cookies from the active tab, and they explain why the tool can audit live pages on demand.

It is lightweight on resources but limited to desktop Chromium browsers

The developer describes a minimal footprint and Manifest V3 compliance, which reduces background execution compared with older extension architectures. That design keeps runtime overhead low during checks, making it suitable for routine audits on a typical desktop environment. The extension cannot run on mobile Chrome because browser extensions are not supported there, so audits require a desktop Chromium browser.

It targets technical users rather than general consumers

The tool is positioned for privacy-minded individuals, web developers, and security auditors who need precise, technical findings rather than an ongoing endpoint protection product. It is compatible with other Chromium-based browsers, which broadens its applicability for developers testing sites across engines. The extension has a focused audience and a niche user base, so it suits users who can interpret fingerprinting and header results themselves.

Practical choice for technical audits, not a continuous protection layer

The extension is a practical diagnostic utility for users who perform occasional security checks or validate site configurations, because it delivers concise, client-side findings and operates within Chrome's extension model. Expect a focused audit workflow rather than background blocking or centralized reporting. For regular use, run the tool after installing new extensions or after changing VPN/proxy settings to confirm that browser behavior matches your privacy expectations.
