What is SecureLint and how does it work?

SecureLint is a Chrome extension that runs entirely in your browser. It scans text you type or paste into any web editor in real time, detects sensitive data (API keys, passwords, tokens, credentials), and masks it before it can leak. It also blocks phishing sites using a 14-layer detection engine before the page fully loads.

Is my data ever sent to a server?

For individual users — no. All detection, masking, and phishing checks happen 100% locally inside your browser. No page content, typed text, or detected secrets are ever transmitted to any server. For Enterprise users, masked incident reports (never raw secrets) can be sent to your organization's admin dashboard only when explicitly enabled by your IT admin.

Does SecureLint work on all websites?

Yes. SecureLint works across all websites — standard inputs, textareas, contenteditable elements, and rich text editors like CodeMirror, Monaco, Ace, TinyMCE, CKEditor, and popular productivity tools like Gmail, Slack, Notion, ChatGPT, and more.

How does phishing detection work?

SecureLint uses a 14-layer engine: bloom filter, URL heuristics, homograph/IDN analysis, typosquat detection, WHOIS domain-age check, SSL certificate validation, Google Safe Browsing, and page-content scanning for credential-harvesting language. If Google Safe Browsing confirms the site is safe, the site is automatically unblocked — no false positives.

What types of secrets does SecureLint detect?

SecureLint detects 100+ secret types including AWS, GCP, and Azure credentials; JWT tokens; OAuth access and refresh tokens; database connection strings (MongoDB, Redis, MySQL, PostgreSQL); private keys and certificates (RSA, EC, PGP); Stripe, Slack, and GitHub API keys; SSNs, Aadhaar numbers, and credit card patterns.

Is SecureLint free to use?

SecureLint is a paid product with Pro and Enterprise plans. The Pro plan is designed for individual developers and security professionals, while Enterprise is built for IT and security teams needing full DLP, admin dashboard, and SLA-backed support. Both plans can be activated instantly from securelint.in.

Can I switch plans or cancel anytime?

Yes. You can upgrade, downgrade, or cancel your subscription at any time from your dashboard. If you cancel, your Pro or Enterprise features remain active until the end of your current billing period.

What payment methods are accepted?

For Indian users we accept all major UPI apps (PhonePe, GPay, Paytm), credit and debit cards, and net banking via Razorpay. For international users we accept PayPal and Google Pay.

Does SecureLint check SSL certificates in real time?

Yes. SecureLint performs a real-time SSL/HTTPS certificate check on every page you visit. If the certificate is expired, self-signed, or the site is running on plain HTTP for a login or payment page, SecureLint raises an immediate alert so you never enter credentials on an insecure connection.

How does the domain age alert work?

Phishing sites are almost always newly registered — often less than 7 days old. SecureLint queries WHOIS data in real time and flags any site where the domain was registered recently, showing you the exact registration date before you interact with the page.

Is SecureLint a VAPT tool?

SecureLint performs a continuous, passive VAPT-style real-time scan directly in your browser. It detects exposed credentials, weak SSL, suspicious domains, phishing indicators, XSS attempts, and clickjacking on every page you visit — without requiring any manual test setup. It is not a replacement for a full penetration test, but gives developers and security teams instant, always-on threat visibility.

What is real-time browser security scanning?

Real-time browser security scanning means SecureLint analyses every page you open, every URL you visit, and every input you type — instantly, before threats can cause damage. It checks for phishing indicators, exposed API keys, SSL validity, domain age, redirect chains, crypto drainers, and XSS payloads — all within milliseconds and entirely inside your browser.

How do I install SecureLint?

Visit the Chrome Web Store, search for 'SecureLint' or click the direct install link on securelint.in. Click 'Add to Chrome', confirm permissions, and SecureLint is active immediately — no account required for the free tier.

Does SecureLint slow down my browser?

No. SecureLint is engineered for sub-millisecond detection using optimised regex engines and a local bloom filter for phishing checks. It runs in a content-script context with minimal CPU and memory footprint — independent benchmark tests show less than 2 ms latency per scan cycle.

What is the Enterprise plan?

Enterprise is designed for IT and security teams. It adds centralized policy management, email DLP and send blocking, WAF and social-domain blocking, incident reporting, admin dashboard, and dedicated support with an SLA. Contact our sales team for pricing.

How does SecureLint detect phishing websites?

SecureLint uses multiple detection layers: domain age analysis, lookalike domain detection, SSL certificate validation, known phishing domain blocklists, and heuristic URL pattern analysis.

Can SecureLint detect phishing links in emails?

Yes. When you open Gmail, Outlook, or any webmail client in Chrome, SecureLint scans all links on the page and flags any that match phishing patterns.

What is phishing and why is it still so effective?

Phishing is the #1 cause of data breaches globally. Attackers create convincing fake websites — often identical copies of real services — and trick users into entering credentials, clicking malicious links, or downloading malware.

Modern phishing attacks are sophisticated: they use recently registered domains (so blocklists haven't caught up), typosquatted URLs (e.g. arnazon.com instead of amazon.com), and valid SSL certificates (so the padlock icon provides false confidence).

Traditional anti-phishing solutions rely on blocklists that are always a step behind. SecureLint uses real-time heuristic analysis to detect new phishing attempts before they appear on any list.

Multi-Layer Phishing Detection

Six independent detection layers — so new threats are caught even before blocklists know about them.

Domain Age Analysis

Newly registered domains (less than 30 days old) are flagged with a prominent warning. Most phishing sites are created hours before attacks launch.

📅

Lookalike Domain Detection

SecureLint uses Levenshtein distance and homoglyph analysis to detect URLs that closely resemble popular legitimate domains — e.g. paypa1.com, g00gle.com.

🔤

SSL Certificate Check

SecureLint verifies SSL certificates for anomalies — self-signed certificates, expired certs, and mismatched domain names are flagged immediately.

🔒

Known Phishing Blocklist

Domains from known phishing databases are blocked automatically. The blocklist is updated continuously with new threat intelligence.

🚫

Malicious Link Scanning

All links on a page — in emails, chat apps, and web pages — are scanned for phishing patterns before you hover or click.

🔗

Crypto Drainer Detection

SecureLint detects known crypto wallet drainer patterns and fake NFT mint pages that attempt to steal cryptocurrency through malicious approvals.

Who Needs Browser Phishing Protection?

Phishing targets everyone — but some roles are hit hardest.

Developers

Developers are prime targets for supply-chain phishing — fake npm registry pages, spoofed GitHub login pages, and credential-harvesting developer tools.

👨‍💻

Finance & Accounting Teams

Attackers specifically target finance staff with convincing bank portal spoofs and invoice fraud campaigns designed to capture login credentials.

💰

Enterprise IT & Security

Security teams use SecureLint to provide an additional detection layer on managed devices — catching phishing attempts that bypass email filters.

🏢

Crypto Users & Traders

Crypto wallet phishing is at an all-time high. SecureLint's drainer detection specifically targets the fake minting and swap pages attackers use to steal funds.
