Microsoft 365 is already dominant in the marketplace and is poised to surpass 75% market share this year. The cloud-based productivity suite interacts with a vast amount of corporate data including email (Outlook Online), individual file storage (OneDrive), and even financials (Excel Online). Its built-in security tools are helpful but inadequate, and organizations would do well to ask a few questions before they deploy Microsoft 365:
Is Microsoft 365 able to block malware, spam and phishing emails?
Are the people accessing Microsoft 365 my employees and are they using devices that are compliant with our security policies?
Does my Microsoft 365 deployment include sensative data, and who is accessing it?
