extuno
Stop malicious extensions and packages.
Extuno scans every version of an extension or package - and the browsers running them - then shows you exactly what an update changed, why it is dangerous, and the action to take. Every version runs through five tests - vulnerability, secret-leak, static, dynamic, and AI code analysis - so nothing reaches your users unchecked.
The update-channel attack, made visible.
A clean extension or package turns malicious one version later. Extuno compares the update against the version before it and flags the escalation before it reaches your users.
New exfiltration
A new outbound channel carrying cookies, tokens, or wallet keys that was absent in the prior version.
Permission creep
Added host permissions, a weakened content policy, or new remote-code paths introduced on update.
Covert beaconing
Hidden loaders and command traffic captured running live in a network-segmented sandbox.
Five tests on every submission.
Each extension or package is checked five ways - vulnerability and secret-leak testing, static and dynamic analysis, and AI code analysis - then diffed against its last version, scored, and reported with evidence.
Watch every dependency, around the clock.
Add extensions and packages to a watchlist. Extuno re-scans on every release and routes alerts to the channels your team already lives in.
- + Scheduled re-scans on each new version

Protect every browser in minutes.
The companion scans installed extensions, runs a server-side deep scan, and blocks malicious sites, trackers, miners, phishing, and dangerous downloads.
