SecureLint is a Chrome extension that brings enterprise-grade security directly into your browser — masking API keys, detecting phishing attacks, validating SSL certificates, and preventing data leaks — all running 100% locally, with zero data sent anywhere.
SecureLint is a browser security Chrome extension built by VAPTLabs. It provides eight security capabilities that run continuously in your browser — detecting threats, masking sensitive data, and alerting you to security risks in real time.
The core insight behind SecureLint is simple: the browser is the most-used — and most-attacked — application on any device, yet it's the least protected. Firewalls protect the network. Antivirus protects the OS. But the browser — where developers paste API keys, click phishing links, and share screens full of credentials — has historically had no dedicated security layer.
SecureLint is that security layer. It runs entirely inside Chrome, requiring no agent installation, no network proxy, no server-side component, and no configuration. Install it and it immediately starts protecting you.
Developers accidentally paste API keys into ChatGPT, share screens with credentials visible, or expose secrets in browser DevTools. SecureLint detects and masks them the moment they appear — across AI tools, web apps, dashboards, and developer tools.
API Key Masking →Attackers create convincing lookalike websites and send malicious links via email. Traditional blocklists are always a step behind. SecureLint analyzes domain age, URL structure, SSL anomalies, and known patterns to detect phishing sites before you enter any credentials.
Phishing Protection →During code reviews, demos, and team calls, sensitive data on screen gets recorded and shared without anyone realizing it. SecureLint masks credentials in real time during Zoom, Meet, Teams, and Loom sessions.
Screen Share Privacy →Without a browser-level DLP control, sensitive data can easily be transmitted — pasted into AI prompts, submitted via web forms, or copied to clipboard. SecureLint provides the browser DLP layer that traditional network DLP misses.
Browser DLP →Invalid, expired, or self-signed SSL certificates are a major indicator of phishing and man-in-the-middle attacks. SecureLint validates SSL certificates on every site you visit and alerts you to any anomalies.
SecureLint operates entirely within your Chrome browser. Here's the flow:
Add SecureLint from the Chrome Web Store in one click. No configuration required.
Content scripts run on every page, scanning for secrets, phishing patterns, and SSL issues in real time.
Regex patterns and entropy analysis identify 100+ secret types. Domain analysis flags suspicious sites.
Detected secrets are visually replaced with ••••••• characters. The underlying data is unchanged.
You receive an in-browser notification with the threat type, location, and recommended action.
80+ provider patterns. Masks AWS, GCP, OpenAI, Stripe, GitHub, and more in real time.
Learn more →Domain age, lookalike URLs, SSL validation, blocklist matching. Multi-layer protection.
Learn more →Enterprise data loss prevention without agents, proxies, or infrastructure.
Learn more →Auto-masks credentials during Zoom, Meet, Teams, and Loom sessions.
Learn more →Identifies Cross-Site Scripting injection attempts in real time.
Checks every SSL certificate for validity, expiry, and domain match.
Detects wallet drainers, fake mint pages, and DeFi phishing attacks.
Developers are the most frequent unintentional secret leakers — copying keys into AI tools, sharing screens, and working with cloud dashboards all day. SecureLint provides a safety net that runs silently in the background.
Security teams use SecureLint as an additional detection layer during assessments and in production environments — catching browser-level threats that network and endpoint tools miss.
Teams managing cloud infrastructure and CI/CD pipelines use SecureLint to prevent credentials from being exposed in browser-accessible configuration panels and dashboards.
Fast-moving teams often sacrifice security hygiene for speed. SecureLint provides automatic protection without requiring developers to change their workflow.
Enterprise deployments use SecureLint via Google Admin force-install to enforce browser security policies across the entire organization with centralized management.
Anyone concerned about phishing, credential theft, and online security can use SecureLint's free tier to get immediate browser protection.
SecureLint has a generous free tier. Upgrade for advanced features.
SecureLint is a Chrome browser extension that provides real-time browser security: API key masking, phishing detection, SSL validation, XSS detection, browser DLP, secret scanning, and crypto drainer protection — all running 100% locally inside Chrome.
Yes. SecureLint is built by VAPTLabs, a security research company. All processing happens locally inside your browser. No page content, credentials, URLs, or user data is ever transmitted to external servers. The extension's permissions are minimal and documented in our privacy policy.
Yes. SecureLint supports force-installation via Google Chrome Enterprise Admin, enabling IT teams to deploy it across an entire organization, configure policies centrally, and receive aggregated security reports.
The free tier includes basic API key detection, phishing protection, and SSL checking. SecureLint Pro adds advanced detection (100+ patterns + custom regex), detailed threat reports, screen share privacy mode, priority support, and advanced DLP controls.
Yes. SecureLint scans all web pages you visit in Chrome, including web apps, cloud dashboards, AI tools, developer tools, email clients, and internal tools. It requires no per-site configuration.
