Throughout the board, the study also confirmed that businesses using at least a person more security instrument to complement the simple email protections supplied in Microsoft 365. On the other hand, their implementation efficacy may differ, the survey discovered.
“Additive equipment contain Microsoft 365 Defender, security awareness coaching technology, a 3rd-party protected email gateway or a third-party specialized anti-phishing insert-on,” the report explained. “There is a vast vary of deployment designs with the use of these tools.”
