Is Isabel Security Components add-on safe?

Clean risk

Isabel Security Components add-on relays messages from supported banking sites to the local bisc native messaging host.

On Isabel, BNP Paribas Fortis, KBC, and related banking domains, the content script listens for page-script-request events and forwards the page's message to the extension background service. The background script adds the browser tab ID and sends the request to Chrome's bisc native messaging host, then returns the native host's response to the page.
