Is Mettl Proctoring safe?

Clean risk

Mettl Proctoring disables other installed extensions during exams and sends proctoring logs to a configured Mettl API.

When an exam starts, Mettl Proctoring uses Chrome's management API to turn off every installed extension except itself, then restores previously enabled extensions during shutdown. It also batches log, network, and navigation events with stored session metadata and posts them to the configured log API, requesting a token from the configured LTI endpoint when needed.

Shared hosts - 5 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
