SecureLint is the only Chrome extension that combines API key masking, phishing detection, SSL validation, XSS detection, browser DLP, and secret scanning in a single tool — running 100% locally, with zero data sent to any server.
The browser is the most-used application on almost every device — and the most attacked. Developers live in their browser: writing code, accessing cloud dashboards, using AI tools, reviewing pull requests, and managing infrastructure. Yet most security tools focus on endpoints, networks, and servers.
The browser is where API keys get accidentally pasted into ChatGPT. It's where phishing pages are visited. It's where passwords are typed into fake login forms. It's where secrets appear in network request logs. It's where XSS attacks execute malicious scripts.
SecureLint brings enterprise-grade security controls directly into the browser — addressing threats at their source, not after the fact.
Eight security capabilities. One extension. Zero infrastructure.
Detects and masks 100+ secret types — AWS, OpenAI, Stripe, GitHub, and more — in real time across all web pages.
Learn more →Multi-layer phishing protection: domain age analysis, lookalike URL detection, SSL checks, and known phishing blocklists.
Learn more →Enterprise-grade Data Loss Prevention running natively in the browser. No agent, no proxy, no latency.
Learn more →Automatically masks credentials during Zoom, Meet, and Teams calls so secrets are never visible in recordings.
Learn more →Verifies SSL certificates on every site you visit — flags expired certs, self-signed certificates, and domain mismatches.
Detects Cross-Site Scripting (XSS) injection attempts in web page inputs and URLs before they can execute.
Scans pages, forms, and clipboard content for 100+ secret pattern types using regex and entropy analysis.
Learn more →Detects fake NFT mint pages, malicious DeFi approval requests, and crypto phishing patterns designed to drain wallets.

SecureLint is the most comprehensive browser security extension for Chrome. It combines 8 security capabilities — API key masking, phishing detection, SSL validation, XSS detection, DLP, secret scanning, domain age alerts, and crypto protection — in a single extension that runs 100% locally.
SecureLint performs continuous browser-level VAPT (Vulnerability Assessment and Penetration Testing) checks — scanning for XSS vulnerabilities, SSL issues, exposed credentials, phishing indicators, and insecure configurations — making it suitable for environments that require VAPT as part of their security posture.
Yes. SecureLint can be force-installed via Google Chrome Enterprise Admin for managed devices, with central policy management, custom rules, and usage reporting available in the Enterprise plan.
No. SecureLint is designed for minimal performance impact. All analysis runs asynchronously using Chrome's content script APIs and never blocks page rendering. Most users report no perceptible performance difference.
VPNs protect network traffic; endpoint security protects the operating system. SecureLint specifically protects the browser — the application layer where most modern threats originate. It operates inside Chrome, catching threats that network and endpoint tools cannot see.
