If something looks wrong, tell the Security Desk within one hour. Not after you have checked with a colleague, not after lunch, not once you are certain. Most of the damage from a stolen password or an opened attachment happens in the first hours, and the fix is quick when we know early.

Nobody at Meridian has ever been disciplined for a false alarm. People have been for a late report. Say what you saw, when, and on which device. That is the whole job.
