How Coro processes user reports
Coro processes a user report based on whether or not a ticket was already raised against that email. In other words, Coro might have identified the email as containing malicious content and already raised a ticket in the console before the user report is received.
Equally, in some cases, Coro might receive a user report for an email that does not meet the threshold for suspicious content, and thus no ticket has been raised.
If Coro has already raised a ticket, the outcome of the user report also depends on whether that ticket has been automatically remediated and closed, or remains open for admin user review.
The following table summarizes each scenario and the action Coro takes:
Ticket raised and open | Ticket closed after review | No ticket raised | |
---|---|---|---|
Reported as Safe | The ticket is marked with feedback from the user report. | The ticket is marked with feedback from the user report and re-opened for operator review. | No action. |
Reported as Phishing | The ticket is marked with feedback from the user report. | The ticket is marked with feedback from the user report. | Coro creates a new ticket of type Reported by user. For more information, see Email Security ticket types. |
In the Ticket Log, Coro marks tickets affected by a user report with phishing or safe:
