What our analysis found
Smoothwall Cloud Filter, used by 100,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can read and change data on all websites, can inject scripts into pages and can observe network requests. It comes from a trusted publisher and was last updated in July 2026.
The extension is a legitimate educational web filtering and monitoring tool. All permissions are required for its core functionality (webRequest for filtering, scripting for page modifications, for user identification, nativeMessaging for agent communication). Data collection (PII, location, web history, user activity) is explicitly disclosed in the Chrome Web Store listing. Observed data flows go to the publisher's own domains (), matching the privacy policy. The background worker was not provided for review, but all other source files show no signs of malicious or unauthorized behavior. The 'Critical' risk-engine score is a false positive driven by the necessary broad permissions.
