SecureLint is a browser security extension that detects and masks API keys, tokens, secrets, and credentials in real time. It validates SSL certificates, alerts users about suspicious and newly registered domains, and helps prevent phishing attacks and crypto-drainer scams. Built with a privacy-first approach, all analysis runs locally in the browser, ensuring sensitive data never leaves your device. Trusted by developers, security professionals, and organizations to browse and work more secure.

👋 Hi Product Hunt, We're excited to introduce SecureLint. As a cybersecurity team, we've spent years performing security assessments for startups, enterprises, and development teams. One recurring issue we observed was that sensitive information—API keys, access tokens, credentials, and other secrets—often gets exposed unintentionally during everyday browsing and development activities. The browser has become the primary workspace for developers and professionals, yet it remains one of the most overlooked security layers. Existing solutions are often complex, expensive, or require data to be sent to external services for analysis. We built SecureLint to make browser security simple, privacy-first, and accessible. SecureLint helps users identify risky websites, detect exposed secrets, and stay protected from phishing and malicious web threats—all while processing data locally within the browser. Our goal is to help individuals and organizations reduce preventable security risks without disrupting their workflow. We'd love to hear your feedback, suggestions, and ideas. Thank you for supporting our launch and being part of the journey! 🚀 — The SecureLint Team
