The PhishArm Chrome Extension for G Suite provides employees to report any kind-of suspicious emails.

The PhishArm extension can help empower employees across an organization to serve as an extension of their IT and InfoSec teams by reporting potential phishing, spam, simulated, or malicious emails.

This will enable an IT or InfoSec team to take immediate action to mitigate the effects of a data breach or security compromise.
