Data encryption is automatically applied to your files and emails, keeping your information secure, whether stored or in transit. Your sensitive documents remain protected even if devices are lost or stolen.
Advanced threat protection helps safeguard against malware, phishing attempts, and other cyber threats. The system scans attachments and links to prevent harmful content from reaching your inbox.
OneDrive offers additional security updates that make accessing your files safer and more convenient. Files are automatically scanned for threats when uploading or downloading.
You can control access permissions for shared documents, allowing you to specify exactly who can view or edit your content. This granular control ensures your work is only accessible to intended recipients.
Security alerts notify you of suspicious activities, such as unusual sign-in attempts or potential data breaches, allowing you to take action quickly.
9) AI-powered insights in Excel
