Splunk SIEM

Splunk Enterprise is a security information and event management (SIEM) platform that can be used with Bitwarden organizations. Organizations can monitor event activity with the Bitwarden Event Logs app on their Splunk dashboard.


Create a Splunk account

Installing the Bitwarden app on Splunk requires a Splunk Enterprise account. Bitwarden event monitoring is available on:

  • Splunk Enterprise


The official Splunk Cloud Classic and Splunk Cloud Victoria apps are in development and not available at this time.

Install Splunk

For on-premise Splunk users, the next step is to install Splunk Enterprise. Follow the Splunk documentation to complete an install of the Splunk Enterprise software. 


Splunk Enterprise versions 8.X are no longer supported. Currently Bitwarden is supported on versions 9.0, 9,1, and 9.2.

Understanding the dashboards

The Dashboard will provide several options for monitoring and visualizing Bitwarden organizational data. The three primary categories of data monitoring include:

  • Bitwarden vault item events

  • Bitwarden organization events

The data displayed on the dashboards will provide information and visualization for a broad variety of searches. More complex queries can be completed by selecting the Search tab at the top of the dashboard.


While searching from the Search page or Dashboards, searches can be designated to a specific timeframe.

Splunk timeframe search
Splunk timeframe search

For on-premises users, the following timeframes are supported for Bitwarden event logs searches:

  • Month to date

  • Year to date

  • Previous week

  • Previous business week

  • Previous month

  • Previous year

  • Last 30 days

  • All time

Query parameters

Set up specific searches by including search queries. Spunk utilizes its search processing language (SPL) method for searching. See Splunk's documentation for additional details on searches.

Search structure:

search | commands1 arguments1 | commands2 arguments2 | ...

An example of a standard search result object:

Splunk search result object
Splunk search result object

The fields shown in the standard search object can be included in any specific search. This includes all of the following values:


Example result


The email of the user performing the action.


Unique id of user performing action.


Name of the user performing an action.


Date of event displayed in YYYY-MM-DD TT:TT:TT format.


Numerical number to identify the device that the action was performed on.


Splunk computed data hash. Learn more about Splunk's data integrity here.


The ip address that performed the event.


Email of the organization member that the action was directed towards.


Unique id of the organization member that the action was directed towards.


Name of organization member that action was directed towards.


The event type code that represents the organization event that occurred. See a complete list of event codes with descriptions here.

Search all:

sourcetype="bitwarden:events" type=*

Filter results by a specific field

In the following example, the search is looking for actingUserName with a * wildcard which will display all results with actingUserName.

sourcetype="bitwarden:events" actingUserName=*

The AND operator is implied in Splunk searches. The following query will search for results containing a specific type AND actingUserName.

sourcetype="bitwarden:events" type=1000 actingUserName="John Doe"

Include multiple commands by separating with |. The following will show results with the top value being ipAddress.

sourcetype="bitwarden:events" type=1115 actingUserName="John Doe" | top ipAddress

  1. Access the Splunk directory and stop Splunk processes.

  2. Clear the bitwarden_events index with -index flag. For example:

    splunk clean eventdata -index bitwaren_events
