Product Ecosystem

One security layer, three surfaces

Real-time protection for your browser and workspace inboxes, connected to a centralized dashboard.

Chrome Extension

Browser Guard

Monitors web pages locally to protect your credentials before sensitive information is submitted over unencrypted connections.

  • Flags credential fields on insecure (HTTP) pages
  • Fast, on-device checks with zero browsing lag
  • Runs silently without tracking your browsing history
Gmail & Outlook Add-ins

Email Scanning

Scans inbound emails right inside your inbox sidebar to catch phishing links and spoofed senders before you click.

  • Flags links where the text disguises a dangerous destination
  • Checks SPF, DKIM, and DMARC to verify genuine senders
  • Live threat scoring powered by Google Cloud Web Risk intelligence
Web Dashboard

Unified Dashboard

A central console for individuals to track scans, and for teams to manage members, domain whitelists, and daily quotas.

  • Complete history of scanned emails and threat scores
  • Custom domain whitelist to eliminate false alerts
  • Personal Pro plans and multi-seat team management
How It Works

From detection to alert, in real time

Browser checks run locally on your machine, while email scanning securely evaluates message content in real time and discards it immediately—nothing is stored.

1

On-Device & In-Inbox Detection

Browser extension inspects active web pages for unencrypted credential submission, while workspace add-ins securely analyze the sender, subject, and links of the email you open.

2

Link & Sender Analysis

Compares link text to actual destination URLs, checks sender authentication records, and scores domains using Google Cloud Web Risk and domain-reputation intelligence.

3

Instant Verdict

Alerts you immediately before submitting credentials on unsafe web pages, and delivers a clear risk card in your inbox sidebar before you interact.

PRIVACY FIRST

Protection without data compromise

StealthShield is built on data minimization. Browser checks execute locally on your machine, and email scans are strictly temporary—your message content is never stored, sold, or shared.

Local Browser InspectionCredential checks execute directly inside your browser. Webpage content and browsing history are never sent to our servers.
Ephemeral Email AnalysisEmails are inspected in memory to generate safety verdicts and are never saved to permanent storage or databases.
Zero Telemetry MonetizationYour data belongs entirely to you. We do not sell, broker, or monetize user data or threat telemetry.
