AI product read

Enterprise endpoint security browser extension that integrates with SkyGuard's locally installed endpoint agent to filter dangerous websites, inspect web content, monitor downloads, and display DLP watermarks

Provides organizations with browser-level security controls by monitoring and filtering web traffic, downloads, and page content through integration with the SkyGuard endpoint security platform

Extension auto-authenticates to local SkyGuard endpoint agent on startup → monitors all tab navigation and reports URLs → agent evaluates URLs for dangerous content → extension sends page source code on request for content inspection → monitors downloads and reports to agent (can block downloads) → displays watermarks on pages as directed by agent for DLP policies

Target users: Enterprise employees whose organizations deploy SkyGuard endpoint security / IT administrators managing endpoint security policies

Cannot verify the actual SkyGuard endpoint agent behavior since it's a separate local application
The extension's full functionality depends on the locally installed SkyGuard DSE agent being present and running

Monetization

No paid features detected

No evidence of paid features, payment APIs, subscription flows, upgrade prompts, or billing UI in the extension source code. The keyword matches for 'pro' are false positives (profile_update, processId, properties). This is an enterprise endpoint security agent helper; licensing would be handled at the organizational deployment level, not through the extension itself.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: No
Reason: The 'login' in this extension is automated machine-to-machine authentication between the browser extension and a locally installed SkyGuard endpoint agent (DSE) on 127.0.0.1:8852. The function cloud_app_login('chrome') is called automatically on startup (line 905) using a hardcoded key 'skyguard' with timestamp-based auth tokens (line 457). There is no user-facing login UI, no credential entry, and no account creation. The session_id and session_token are obtained programmatically from the local agent. The user does not need to authenticate to use the extension.
