Collect logs from Microsoft M365 Defender with Elastic Agent.
What is an Elastic integration?
This integration is powered by Elastic Agent. Elastic Agent is a single, unified way to add monitoring for logs, metrics, and other types of data to a host. It can also protect hosts from security threats, query data from operating systems, forward data from remote services or hardware, and more. Refer to our documentation for a detailed comparison between Beats and Elastic Agent.
Prefer to use Beats for this use case? See Filebeat modules for logs or Metricbeat modules for metrics.
See the integrations quick start guides to get started:
The Microsoft 365 Defender integration allows you to monitor Incident (Microsoft Graph Security API) and Event (Streaming API) Logs. Microsoft 365 Defender is a unified pre and post-breach enterprise defense suite that natively coordinates detection, prevention, investigation, and response across endpoints, identities, email, and applications to provide integrated protection against sophisticated attacks.
Use the Microsoft 365 Defender integration to collect and parse data from the Microsoft Azure Event Hub, Microsoft Graph Security v1.0 REST API and Microsoft 365 Defender API. Then visualise that data in Kibana.
For example, you could use the data from this integration to consolidate and correlate security alerts from multiple sources. Also, by looking into the alert and incident, a user can take an appropriate action in the Microsoft 365 Defender Portal.
The Microsoft 365 Defender integration collects logs for three types of events: Event, Incident and Log.
Event (Recommended): This data streams leverages the M365 Defender Streaming API to collect Alert, Device, Email, App and Identity Events. Events are streamed to an Azure Event Hub. For a list of Supported Events exposed by the Streaming API and supported by Elastic's integration, please see Microsoft's documentation here.
Incidents and Alerts (Recommended): This data streams leverages the Microsoft Graph Security API to ingest a collection of correlated alert instances and associated metadata that reflects the story of an attack in M365D. Incidents stemming from Microsoft 365 Defender, Microsoft Defender for Endpoint, Microsoft Defender for Office 365, Microsoft Defender for Identity, Microsoft Defender for Cloud Apps, and Microsoft Purview Data Loss Prevention are supported by this integration.
Log (Deprecated): This data stream is not recommend as it collects incidents from the SIEM API that Microsoft plans to deprecate. The data stream will be removed when Microsoft has deprecated the SIEM API. If you are currently using this data stream, we recommend moving to the Incident data stream which supports Microsoft's Graph Security API. The incidents data stream collects the same data as the log data stream. Please see Microsoft's documentation on migration from SIEM API to Graph Security API for more information.
You need Elasticsearch for storing and searching your data and Kibana for visualizing and managing it. You can use our hosted Elasticsearch Service on Elastic Cloud, which is recommended, or self-manage the Elastic Stack on your own hardware.
This module has used Microsoft Azure Event Hub for Streaming Event, Microsoft Graph Security v1.0 REST API for Incident and Microsoft 365 Defender API for Log data streams.
For Event, in filebeat Azure Event Hub input, state such as leases on partitions and checkpoints in the event stream are shared between receivers using an Azure Storage container. For this reason, as a prerequisite to using this input, users will have to create or use an existing storage account.

Exported fields
| Field | Description | Type |
|---|---|---|
@timestamp | Event timestamp. | date |
cloud.account.id | The cloud account or organization id used to identify different entities in a multi-tenant environment. Examples: AWS account id, Google Cloud ORG Id, or other unique identifier. | keyword |
cloud.availability_zone | Availability zone in which this host is running. | keyword |
cloud.image.id | Image ID for the cloud instance. | keyword |
cloud.instance.id | Instance ID of the host machine. | keyword |
cloud.instance.name | Instance name of the host machine. | keyword |
cloud.machine.type | Machine type of the host machine. | keyword |
cloud.project.id | Name of the project in Google Cloud. | keyword |
cloud.provider | Name of the cloud provider. Example values are aws, azure, gcp, or digitalocean. | keyword |
cloud.region | Region in which this host is running. | keyword |
container.id | Unique container id. | keyword |
container.image.name | Name of the image the container was built on. | keyword |
container.labels | Image labels. | object |
container.name | Container name. | keyword |
data_stream.dataset | Data stream dataset. | constant_keyword |
data_stream.namespace | Data stream namespace. | constant_keyword |
data_stream.type | Data stream type. | constant_keyword |
destination.domain | The domain name of the destination system. This value may be a host name, a fully qualified domain name, or another host naming format. The value may derive from the original event or be added from enrichment. | keyword |
destination.ip | IP address of the destination (IPv4 or IPv6). | ip |
destination.port | Port of the destination. | long |
ecs.version | ECS version this event conforms to. ecs.version is a required field and must exist in all events. When querying across multiple indices -- which may conform to slightly different ECS versions -- this field lets integrations adjust to the schema version of the events. | keyword |
email.direction | The direction of the message based on the sending and receiving domains. | keyword |
email.from.address | The email address of the sender, typically from the RFC 5322 From: header field. | keyword |
email.local_id | Unique identifier given to the email by the source that created the event. Identifier is not persistent across hops. | keyword |
email.subject | A brief summary of the topic of the message. | keyword |
email.subject.text | Multi-field of email.subject. | match_only_text |
email.to.address | The email address of recipient | keyword |
event.created | event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used. | date |
event.dataset | Event dataset. | constant_keyword |
event.id | Unique ID to describe the event. | keyword |
event.module | Event module. | constant_keyword |
event.original | Raw text message of entire event. Used to demonstrate log integrity or where the full log message (before splitting it up in multiple parts) may be required, e.g. for reindex. This field is not indexed and doc_values are disabled. It cannot be searched, but it can be retrieved from _source. If users wish to override this and index this field, please see Field data types in the Elasticsearch Reference. | keyword |
event.outcome | This is one of four ECS Categorization Fields, and indicates the lowest level in the ECS category hierarchy. event.outcome simply denotes whether the event represents a success or a failure from the perspective of the entity that produced the event. Note that when a single transaction is described in multiple events, each event may populate different values of event.outcome, according to their perspective. Also note that in the case of a compound event (a single event that contains multiple logical events), this field should be populated with the value that best captures the overall success or failure from the perspective of the event producer. Further note that not all events will have an associated outcome. For example, this field is generally not populated for metric events, events with event.type:info, or any events for which an outcome does not make logical sense. | keyword |
event.provider | Source of the event. Event transports such as Syslog or the Windows Event Log typically mention the source of an event. It can be the name of the software that generated the event (e.g. Sysmon, httpd), or of a subsystem of the operating system (kernel, Microsoft-Windows-Security-Auditing). | keyword |
event.severity | The numeric severity of the event according to your event source. What the different severity values mean can be different between sources and use cases. It's up to the implementer to make sure severities are consistent across events from the same source. The Syslog severity belongs in log.syslog.severity.code. event.severity is meant to represent the severity according to the event source (e.g. firewall, IDS). If the event source does not publish its own severity, you may optionally copy the log.syslog.severity.code to event.severity. | long |
file.directory | Directory where the file is located. It should include the drive letter, when appropriate. | keyword |
file.extension | File extension, excluding the leading dot. Note that when the file name has multiple extensions (example.tar.gz), only the last one should be captured ("gz", not "tar.gz"). | keyword |
file.hash.md5 | MD5 hash. | keyword |
file.hash.sha1 | SHA1 hash. | keyword |
file.hash.sha256 | SHA256 hash. | keyword |

file.x509.not_after | Time at which the certificate is no longer considered valid. | date |
file.x509.serial_number | Unique serial number issued by the certificate authority. For consistency, if this value is alphanumeric, it should be formatted without colons and uppercase characters. | keyword |
host.architecture | Operating system architecture. | keyword |
host.containerized | If the host is a container. | boolean |
host.domain | Name of the domain of which the host is a member. For example, on Windows this could be the host's Active Directory domain or NetBIOS domain name. For Linux this could be the domain of the host's LDAP provider. | keyword |
host.hostname | Hostname of the host. It normally contains what the hostname command returns on the host machine. | keyword |
host.id | Unique host id. As hostname is not always unique, use values that are meaningful in your environment. Example: The current usage of beat.name. | keyword |
host.ip | Host ip addresses. | ip |
host.mac | Host mac addresses. | keyword |
host.name | Name of the host. It can contain what hostname returns on Unix systems, the fully qualified domain name, or a name specified by the user. The sender decides which value to use. | keyword |

}Exported fields
| Field | Description | Type |
|---|---|---|
@timestamp | Event timestamp. | date |
cloud.account.id | The cloud account or organization id used to identify different entities in a multi-tenant environment. Examples: AWS account id, Google Cloud ORG Id, or other unique identifier. | keyword |
cloud.availability_zone | Availability zone in which this host is running. | keyword |
cloud.image.id | Image ID for the cloud instance. | keyword |
cloud.instance.id | Instance ID of the host machine. | keyword |
cloud.instance.name | Instance name of the host machine. | keyword |
cloud.machine.type | Machine type of the host machine. | keyword |
cloud.project.id | Name of the project in Google Cloud. | keyword |
cloud.provider | Name of the cloud provider. Example values are aws, azure, gcp, or digitalocean. | keyword |
cloud.region | Region in which this host is running. | keyword |
container.id | Unique container id. | keyword |
container.image.name | Name of the image the container was built on. | keyword |
container.labels | Image labels. | object |
container.name | Container name. | keyword |
data_stream.dataset | Data stream dataset. | constant_keyword |
data_stream.namespace | Data stream namespace. | constant_keyword |
data_stream.type | Data stream type. | constant_keyword |
ecs.version | ECS version this event conforms to. ecs.version is a required field and must exist in all events. When querying across multiple indices -- which may conform to slightly different ECS versions -- this field lets integrations adjust to the schema version of the events. | keyword |
email.delivery_timestamp | The date and time when the email message was received by the service or client. | date |
email.direction | The direction of the message based on the sending and receiving domains. | keyword |
email.from.address | The email address of the sender, typically from the RFC 5322 From: header field. | keyword |
email.subject | A brief summary of the topic of the message. | keyword |
email.subject.text | Multi-field of email.subject. | match_only_text |
email.to.address | The email address of recipient | keyword |
event.action | The action captured by the event. This describes the information in the event. It is more specific than event.category. Examples are group-add, process-started, file-created. The value is normally defined by the implementer. | keyword |
event.category | This is one of four ECS Categorization Fields, and indicates the second level in the ECS category hierarchy. event.category represents the "big buckets" of ECS categories. For example, filtering on event.category:process yields all events relating to process activity. This field is closely related to event.type, which is used as a subcategory. This field is an array. This will allow proper categorization of some events that fall in multiple categories. | keyword |
event.created | event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used. | date |
event.dataset | Event dataset. | constant_keyword |
event.id | Unique ID to describe the event. | keyword |
event.kind | This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. event.kind gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data coming in at a regular interval or not. | keyword |
event.module | Event module. | constant_keyword |
event.original | Raw text message of entire event. Used to demonstrate log integrity or where the full log message (before splitting it up in multiple parts) may be required, e.g. for reindex. This field is not indexed and doc_values are disabled. It cannot be searched, but it can be retrieved from _source. If users wish to override this and index this field, please see Field data types in the Elasticsearch Reference. | keyword |
event.provider | Source of the event. Event transports such as Syslog or the Windows Event Log typically mention the source of an event. It can be the name of the software that generated the event (e.g. Sysmon, httpd), or of a subsystem of the operating system (kernel, Microsoft-Windows-Security-Auditing). | keyword |
event.severity | The numeric severity of the event according to your event source. What the different severity values mean can be different between sources and use cases. It's up to the implementer to make sure severities are consistent across events from the same source. The Syslog severity belongs in log.syslog.severity.code. event.severity is meant to represent the severity according to the event source (e.g. firewall, IDS). If the event source does not publish its own severity, you may optionally copy the log.syslog.severity.code to event.severity. | long |
event.type | This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. event.type represents a categorization "sub-bucket" that, when used along with the event.category field values, enables filtering events down to a level appropriate for single visualization. This field is an array. This will allow proper categorization of some events that fall in multiple event types. | keyword |
event.url | URL linking to an external system to continue investigation of this event. This URL links to another system where in-depth investigation of the specific occurrence of this event can take place. Alert events, indicated by event.kind:alert, are a common use case for this field. | keyword |
file.hash.sha1 | SHA1 hash. | keyword |
file.hash.sha256 | SHA256 hash. | keyword |
file.name | Name of the file including the extension, without the directory. | keyword |
file.path | Full path to the file, including the file name. It should include the drive letter, when appropriate. | keyword |
file.path.text | Multi-field of file.path. | match_only_text |
file.size | File size in bytes. Only relevant when file.type is "file". | long |
group.id | Unique identifier for the group on the system/platform. | keyword |
group.name | Name of the group. | keyword |
host.architecture | Operating system architecture. | keyword |
host.containerized | If the host is a container. | boolean |
host.domain | Name of the domain of which the host is a member. For example, on Windows this could be the host's Active Directory domain or NetBIOS domain name. For Linux this could be the domain of the host's LDAP provider. | keyword |
host.hostname | Hostname of the host. It normally contains what the hostname command returns on the host machine. | keyword |
host.id | Unique host id. As hostname is not always unique, use values that are meaningful in your environment. Example: The current usage of beat.name. | keyword |
host.ip | Host ip addresses. | ip |
host.mac | Host mac addresses. | keyword |
host.name | Name of the host. It can contain what hostname returns on Unix systems, the fully qualified domain name, or a name specified by the user. The sender decides which value to use. | keyword |
host.os.build | OS build information. | keyword |
host.os.codename | OS codename, if any. | keyword |
host.os.family | OS family (such as redhat, debian, freebsd, windows). | keyword |
host.os.kernel | Operating system kernel version as a raw string. | keyword |
host.os.name | Operating system name, without the version. | keyword |
host.os.name.text | Multi-field of host.os.name. | text |
host.os.platform | Operating system platform (such centos, ubuntu, windows). | keyword |
host.os.version | Operating system version as a raw string. | keyword |
host.type | Type of host. For Cloud providers this can be the machine type like t2.medium. If vm, this could be the container, for example, or other information meaningful in your environment. | keyword |
input.type | Input type | keyword |
log.offset | Log offset | long |

}Exported fields
| Field | Description | Type |
|---|---|---|
@timestamp | Event timestamp. | date |
cloud.account.id | The cloud account or organization id used to identify different entities in a multi-tenant environment. Examples: AWS account id, Google Cloud ORG Id, or other unique identifier. | keyword |
cloud.availability_zone | Availability zone in which this host is running. | keyword |
cloud.image.id | Image ID for the cloud instance. | keyword |
cloud.instance.id | Instance ID of the host machine. | keyword |
cloud.instance.name | Instance name of the host machine. | keyword |
cloud.machine.type | Machine type of the host machine. | keyword |
cloud.project.id | Name of the project in Google Cloud. | keyword |
cloud.provider | Name of the cloud provider. Example values are aws, azure, gcp, or digitalocean. | keyword |
cloud.region | Region in which this host is running. | keyword |
container.id | Unique container id. | keyword |
container.image.name | Name of the image the container was built on. | keyword |
container.labels | Image labels. | object |
container.name | Container name. | keyword |
data_stream.dataset | Data stream dataset. | constant_keyword |
data_stream.namespace | Data stream namespace. | constant_keyword |
data_stream.type | Data stream type. | constant_keyword |
ecs.version | ECS version this event conforms to. ecs.version is a required field and must exist in all events. When querying across multiple indices -- which may conform to slightly different ECS versions -- this field lets integrations adjust to the schema version of the events. | keyword |
error.message | Error message. | match_only_text |
event.action | The action captured by the event. This describes the information in the event. It is more specific than event.category. Examples are group-add, process-started, file-created. The value is normally defined by the implementer. | keyword |
event.category | This is one of four ECS Categorization Fields, and indicates the second level in the ECS category hierarchy. event.category represents the "big buckets" of ECS categories. For example, filtering on event.category:process yields all events relating to process activity. This field is closely related to event.type, which is used as a subcategory. This field is an array. This will allow proper categorization of some events that fall in multiple categories. | keyword |
event.created | event.created contains the date/time when the event was first read by an agent, or by your pipeline. This field is distinct from @timestamp in that @timestamp typically contain the time extracted from the original event. In most situations, these two timestamps will be slightly different. The difference can be used to calculate the delay between your source generating an event, and the time when your agent first processed it. This can be used to monitor your agent's or pipeline's ability to keep up with your event source. In case the two timestamps are identical, @timestamp should be used. | date |
event.dataset | Event dataset | constant_keyword |
event.end | event.end contains the date when the event ended or when the activity was last observed. | date |
event.id | Unique ID to describe the event. | keyword |
event.kind | This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. event.kind gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data coming in at a regular interval or not. | keyword |
event.module | Event module | constant_keyword |
event.provider | Source of the event. Event transports such as Syslog or the Windows Event Log typically mention the source of an event. It can be the name of the software that generated the event (e.g. Sysmon, httpd), or of a subsystem of the operating system (kernel, Microsoft-Windows-Security-Auditing). | keyword |
event.severity | The numeric severity of the event according to your event source. What the different severity values mean can be different between sources and use cases. It's up to the implementer to make sure severities are consistent across events from the same source. The Syslog severity belongs in log.syslog.severity.code. event.severity is meant to represent the severity according to the event source (e.g. firewall, IDS). If the event source does not publish its own severity, you may optionally copy the log.syslog.severity.code to event.severity. | long |
event.start | event.start contains the date when the event started or when the activity was first observed. | date |
event.timezone | This field should be populated when the event's timestamp does not include timezone information already (e.g. default Syslog timestamps). It's optional otherwise. Acceptable timezone formats are: a canonical ID (e.g. "Europe/Amsterdam"), abbreviated (e.g. "EST") or an HH:mm differential (e.g. "-05:00"). | keyword |
event.type | This is one of four ECS Categorization Fields, and indicates the third level in the ECS category hierarchy. event.type represents a categorization "sub-bucket" that, when used along with the event.category field values, enables filtering events down to a level appropriate for single visualization. This field is an array. This will allow proper categorization of some events that fall in multiple event types. | keyword |
