Learn more by watching this video.

Tip

For a quick list of policies to define, see Protect against threats.

Defender for Office 365 Policies

The policies that are defined for your organization determine the behavior and protection level for predefined threats. Policy options are extremely flexible. For example, your organization's security team can set fine-grained threat protection at the user, organization, recipient, and domain level. It is important to review your policies regularly because new threats and challenges emerge daily.

• Safe Attachments: Provides zero-day protection to safeguard your messaging system, by checking email attachments for malicious content. It routes all messages and attachments that do not have a virus/malware signature to a special environment, and then uses machine learning and analysis techniques to detect malicious intent. If no suspicious activity is found, the message is forwarded to the mailbox. To learn more, see Set up Safe Attachments policies.

• Safe Links: Provides time-of-click verification of URLs, for example, in emails messages and Office files. Protection is ongoing and applies across your messaging and Office environment. Links are scanned for each click: safe links remain accessible and malicious links are dynamically blocked. To learn more, see Set up Safe Links policies.

• Safe Attachments for SharePoint, OneDrive, and Microsoft Teams: Protects your organization when users collaborate and share files, by identifying and blocking malicious files in team sites and document libraries. To learn more, see Turn on Defender for Office 365 for SharePoint, OneDrive, and Microsoft Teams.

• Anti-phishing protection in Defender for Office 365: Detects attempts to impersonate your users and internal or custom domains.
