View or edit policies in Microsoft Defender for Business
In Defender for Business, security settings are configured through policies that are applied to devices. To help simplify your setup and configuration experience, Defender for Business includes preconfigured policies to help protect your company's devices as soon as they are onboarded. You can use the default policies, edit policies, or create your own policies.
This article describes how to:
- Get an overview of your default policies
- View your existing policies
- Edit an existing policy
- Create a new policy
Note
The procedures in this article describe how to view, edit, and create security policies in the Microsoft 365 Defender portal (https://security.microsoft.com). If you're using Microsoft Intune, see Manage endpoint security in Microsoft Intune.
Default policies in Defender for Business
In Defender for Business, there are two main types of policies to protect your company's devices:
- Next-generation protection policies, which determine how Microsoft Defender Antivirus and other threat protection features are configured
- Firewall policies, which determine what network traffic is permitted to flow to and from your company's devices
View your existing policies
Go to the Microsoft 365 Defender portal (https://security.microsoft.com), and sign in.
In the navigation pane, choose Device configuration. Policies are organized by operating system (such as Windows client) and policy type (such as Next-generation protection and Firewall).
Select an operating system tab (for example, Windows clients), and then review the list of policies under the Next-generation protection and Firewall categories.
To view more details about a policy, select its name. A side pane will open that provides more information about that policy, such as which devices are protected by that policy.
Edit an existing policy
Go to the Microsoft 365 Defender portal (https://security.microsoft.com), and sign in.
In the navigation pane, choose Device configuration. Policies are organized by operating system (such as Windows client) and policy type (such as Next-generation protection and Firewall).
Select an operating system tab (for example, Windows clients), and then review the list of policies under the Next-generation protection and Firewall categories.
To edit a policy, select its name, and then choose Edit.
On the General information tab, review the information. If necessary, you can edit the description. Then choose Next.
On the Device groups tab, determine which device groups should receive this policy.
- To keep the selected device group as it is, choose Next.
- To remove a device group from the policy, select Remove.
- To set up a new device group, select Create new group, and then set up your device group. (To get help with this task, see Device groups in Defender for Business.)
- To apply the policy to another device group, select Use existing group.
After you have specified which device groups should receive the policy, choose Next.
On the Configuration settings tab, review the settings. If necessary, you can edit the settings for your policy. To get help with this task, see the following articles:
After you have specified your next-generation protection settings, choose Next.
On the Review your policy tab, review the general information, targeted devices, and configuration settings.
- Make any needed changes by selecting Edit.

Create a new policy
Go to the Microsoft 365 Defender portal (https://security.microsoft.com), and sign in.
In the navigation pane, choose Device configuration. Policies are organized by operating system (such as Windows client) and policy type (such as Next-generation protection and Firewall).
Select an operating system tab (for example, Windows clients), and then review the list of Next-generation protection policies.
Under Next-generation protection or Firewall, select + Add.
On the General information tab, take the following steps:
- Specify a name and description. This information will help you and your team identify the policy later on.
- Review the policy order, and edit it if necessary. (For more information, see Policy order.)
- Choose Next.
On the Device groups tab, either create a new device group, or use an existing group. Policies are assigned to devices through device groups. Here are some things to keep in mind:
- Initially, you might only have your default device group, which includes the devices people in your company are using to access company data and email. You can keep and use your default device group.
- Create a new device group to apply a policy with specific settings that are different from the default policy.
- When you set up your device group, you specify certain criteria, such as the operating system version. Devices that meet the criteria are included in that device group, unless you exclude them.
- All device groups, including the default and custom device groups that you define, are stored in Azure Active Directory (Azure AD).
To learn more about device groups, see Device groups in Defender for Business.
On the Configuration settings tab, specify the settings for your policy, and then choose Next. For more information about the individual settings, see Configuration settings for Defender for Business.
On the Review your policy tab, review the general information, targeted devices, and configuration settings.
- Make any needed changes by selecting Edit.
- When you're ready to proceed, choose Create policy.
