API Key Masking & Phishing Detection — All in One Extension.
From real-time credential leak prevention to enterprise email DLP — SecureLint stops API keys, passwords, and secrets from leaking across every web editor, email client, and tool you use.
1 / 6
The full toolkit
Six ways SecureLint protects you — one install. Always on.
Instant Detection
100+ regex patterns scan every keystroke for AWS keys, Stripe secrets, JWT tokens, and more — entirely inside your browser, zero latency.
- STRIPE_KEY=sk_live_a1b2c3AWS_SECRET=wJalrXUtnFEMDB_PASSWORD=hunter2!xyz99
Real-time Masking
Detected secrets are replaced with ████ blocks the moment they appear. Original stays in memory — masked on-screen. Nothing leaves the tab.
- ⚠security-alert@g00gle.supportPhishing Detected
Phishing Detection
500+ tracked brands, domain-age checks, and lookalike analysis flag fake sites in milliseconds — before the page finishes loading.
- Inbox (47)ComposeAWS AlertsSlack DMs🛡️Send Blocked · Secrets Detected
Email DLP
Intercepts outbound Gmail sends containing API keys or PII — masking content and blocking accidental sends before they reach the wrong inbox.
- CriticalHighMediumLow
Severity Triage
Every finding is tagged Critical, High, Medium, or Low. A live counter per session shows exactly what was caught and when.
- PhishingXSS GuardSecrets
14-Layer Engine
Real-time phishing mail detection with trust scores, brand impersonation alerts, crypto drain guards, HIBP breach checks, SSL validation — every layer runs silently in parallel.
SecureLint · Email Security
Catches phishing emails before you click.
Every inbound email is silently scanned — SPF, DKIM and DMARC signals checked, every link scored for threat probability, and attachments fingerprinted. You see a clear 0–100 trust score before you ever open anything.
- SPF · DKIM · DMARC signal analysis
- Malicious link & attachment scoring
- Real-time threat score (0 – 100)
- 100% local — no email data leaves your browser
SPF –DMARC ×
Phishing(Critical)100/100
SPF softfail — sender weakly authorised
DKIM not signed
DMARC policy failed — domain alignment broken
Malicious URL (threat score 40/100): prismatic-elf-f0328c.netlify.app
Reply-To redirects to free mail (gmail.com) — credential harvest likely

SecureLint · Meeting Mode
Masks secrets the second a call starts.
Meeting Mode detects active Zoom, Meet, or Teams sessions. The moment a call begins, SecureLint instantly blurs API keys, credentials and secrets across every open tab — so sensitive data never appears on screen during a demo, interview, or live review.
- Auto-detects Google Meet, Zoom & Teams
- Masks Jira, Stripe, Razorpay, OpenAI & more
- Protects every open tab simultaneously
- Lifts instantly when the call ends
SecureLint · Link Guard
Stops phishing links before you click.
The moment you open a suspicious email and hover over a link, SecureLint silently checks its domain, reputation score, SSL status, and brand impersonation signals — then blocks your click if the link is unsafe.
- Scans every link before you click
- Flags phishing, impersonation & brand spoofing
- Shows trust score with a live visual gauge
- Works silently inside Gmail, Outlook & Webmail
