Everything you need to protect sensitive data

From real-time secret detection to enterprise-grade DLP — SecureLint keeps your credentials safe across every tool you use.

Universal Editor Support

Works in all web editors: CodeMirror, Monaco, Ace, TinyMCE, CKEditor, Google Docs, Notion, Jira, Confluence — and any contenteditable field.

4-Level Risk Classification

Every detected secret is scored: Critical, High, Medium, or Low — so you know exactly what to fix first.

Context-Aware Masking

Dev mode shows partial masks (sk-1234****5678). Writing mode uses full masking (***API_KEY***). Adapts to your workflow automatically.

100+ Detection Patterns

AWS, GCP, Azure credentials, JWT tokens, DB connection strings, private keys, Stripe/Twilio/SendGrid keys, SSNs, credit cards, and more.

Phishing Mail Detection

New

Detects phishing emails in Gmail, Outlook, and Yahoo Mail. Blocks the reply button and alerts you in real-time before you engage.

Enterprise Email DLP

Enterprise

When an employee tries to send company data to a personal domain, SecureLint blocks the send button and notifies the IT admin.

Enterprise Incident Reporting

Enterprise

IT admins get centralized dashboards showing masked secret detection events across the entire workforce.

Smart Floating Widget

A subtle floating icon shows detected secrets count, color-coded by severity. Move it anywhere — smart positioning opens up or down based on location.

AI Brand Detection

New

Identifies any company worldwide in 100+ languages and verifies the domain matches. Banks, airlines, telecom, government — any brand, any country.

Clickjacking Shield

Detects invisible overlays that hijack your clicks. Automatically disables them so your clicks always land exactly where you intend.

Clipboard Guard

Blocks pastejacking. If a page silently replaces what you copied, SecureLint detects it and restores your original clipboard content instantly.

Multi-Layer AI Engine

Advanced AI detection with automatic failover across multiple models. Always on, always analysing every page in real time — even with encrypted or obfuscated code.

Password Breach Monitor

Checks passwords against HaveIBeenPwned in real-time. Warns you immediately if your password appeared in any known data breach. Privacy-safe — no plain-text is sent.

Link Hover Scanner

Hover any link to see its trust score before clicking. Works on emails, social media, forums, and anywhere links appear.

Real-time Desktop Alerts

Instant desktop notifications when a dangerous site is detected. A full-page warning overlay blocks scam content before you can interact with it.

Wallet Drainer Detection

Scans every page for wallet-draining code. Detects 15+ known drainer kits and malicious transaction requests before they can access your crypto.

JS Code Analysis

AI reads the actual JavaScript on suspicious pages to understand what it does. Catches hidden drainers that disguise themselves behind encrypted or obfuscated code.

Manual URL Checker

Paste any URL to get an instant AI-powered trust score with detailed risk breakdown — before you ever visit the site.

SSL & DNS Verification

Verifies SSL certificates are valid and not expired, and confirms the domain actually resolves to a real server. Expired SSL or phantom DNS = flagged immediately.

100+ Language Scam Detection

Detects scam patterns written in over 100 languages. No attacker can evade detection just by switching to a non-English script.

Crowd-Powered Protection

Shared threat cache across all users. The moment one person encounters a scam, every other user is instantly protected. Faster scans, smarter detection.

Scan History & Weekly Stats

A personal weekly stats dashboard: threats blocked, warnings given, safe sites verified, and secrets masked — all in one view.

Draggable Widget

Move the SecureLint indicator anywhere on screen. Smart positioning automatically opens the panel up or down based on where it sits.

Zero Data Transmission

All detection, masking, and phishing checks happen 100% locally inside your browser. No page content or typed text is ever sent to any server.
