Is Osprey: Browser Protection safe?

Clean risk

Osprey: Browser Protection sends checked page URLs to alphaMountain and Seclookup for security filtering.

When you navigate to HTTP or HTTPS pages, the extension checks the URL against remote security services. It POSTs the full URL to api.alphamountain.ai/category/uri and sends the encoded URL to api.seclookup.com/api/v1/scan/api, then uses the responses to decide whether to block or warn.

Shared hosts - 3 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.
