A browser extension that detects when other installed extensions are secretly sending your browsing data to third parties
Hundreds of Chrome extensions silently exfiltrate browsing history, form data, and AI chat logs to data brokers after gaining user trust over months or years. Existing tools like Guardio rely on reputation blocklists and can't catch newly-turned-malicious extensions or supply-chain-compromised ones that have clean histories. This tool runs local behavioral runtime analysis on every installed extension, flagging real outbound data exfiltration as it happens rather than matching against a database of known-bad signatures.

Gap Assessment
3 tools exist (Guardio, Extension Guard (chrome-stats.com), Malwarebytes Browser Guard) but gaps remain: Reputation-database approach cannot catch trusted extensions that turn malicious after a supply-chain compromise or a silent update, because those extensions have clean histories at the point they go bad.; Permission-based heuristics only, no runtime behavioral analysis. Does not monitor actual network calls or detect active exfiltration. Small user base with no standalone product..

| Product | Does | Missing |
|---|---|---|
| Guardio | AI-driven threat protection extension that blocks malicious sites and flags risky extensions using reputation databases and known-threat signatures. Millions of users. | Reputation-database approach cannot catch trusted extensions that turn malicious after a supply-chain compromise or a silent update, because those extensions have clean histories at the point they go bad. |
| Extension Guard (chrome-stats.com) | Flags extensions with risky permission combinations using Chrome-Stats database metadata. | Permission-based heuristics only, no runtime behavioral analysis. Does not monitor actual network calls or detect active exfiltration. Small user base with no standalone product. |
| Malwarebytes Browser Guard | Blocks malicious URLs, trackers, and known-bad scripts. General web threat protection. | Not focused on extension-to-extension behavioral monitoring; cannot detect a legitimate-looking extension silently POSTing form data or cookies to a data broker domain. |
