In that case, you probably have files and documents related to various programs and platforms: Word, Excel, PowerPoint, Publisher, Access, Teams, Exchange, OneDrive, SharePoint, and most importantly, Outlook. Suppose you're using Office 365 as a primary service. You, as a user, are responsible for keeping data going into the platform secure and in a readable (not corrupted) state. To summarize, Microsoft is responsible for processing your data and allowing continuous access to it. Internal Security refers to countering accidental file deletion, unauthorized access to malicious third parties, employee error, etc.Įxternal Security refers to countering malware attacks (specifically, ransomware), viruses, rogue apps, and similar threats.

On the other hand, the user is responsible for internal and external data security. Office 365 covers infrastructure-level security – physical, logical, and application-level security. The service isn't concerned with the readability of the data. See, Microsoft simply ensures that your data is available. And if data gets corrupted accidentally due to a disaster or a cyberattack, things can get nasty. Nonetheless, Office 365 enables data access in whatever form the user has provided. This way, if a data center fails, the user will be switched to another one and won't notice any downtime regarding data access. They ensure constant data access to users via data replication and datacenter-to-datacenter geo-redundancy. Microsoft's primary purpose for Office 365 is to maintain uptime of the service at all costs. Now, many users perceive that Microsoft 365 takes care of everything, from data storage to cybersecurity enhancement. If left unprotected, M365 can pose data control issues, security vulnerabilities, and regulatory exposure. While online access is convenient, users must mitigate the risk of data loss and avoid losing access to their email. Microsoft 365 is a cloud service allowing individual users to access their data from anywhere, at any time. Microsoft 365 is a virtual version of the offline Microsoft Office software, with several extra options to access – Outlook, SharePoint, Exchange, OneDrive, and Teams. We will follow this practice throughout the article. Nonetheless, Office 365 and Microsoft 365 are often used interchangeably to describe the complete service. Disclaimer: Microsoft Office 365 is embedded within Microsoft 365.
