What does Splunk do with personal data?
Monitor application reliability, investigate errors and diagnose incidents. That is how Privacyboard describes a typical use of Splunk, as a starting point you can edit.
The data usually involved: error events, request metadata, IP addresses, user identifiers and application logs where configured.
Is Splunk a processor or a controller?
Most customers use Splunk as a processor: it handles personal data on their instructions, for the purposes they set. That is the common reading for monitoring tools and it is what Privacyboard suggests.
As a processor, it needs a written agreement with you under Article 28, and you should know which subprocessors it uses. Confirm the role against your own agreement, because the way you use a tool can change it.
Where does Splunk store personal data?
Splunk does not have one fixed location for every customer. The location depends on the plan, the account and the services you enable.
How to find yours: Look at the address you log in to or your project settings.
Even when the main location is in the EU, ask whether subprocessors or support access involve a transfer outside the EEA, and record it if so.
Does Splunk have a data processing agreement?
Checked on 1 November 2026. Vendors change their pages, so check the date.
Yes. Splunk publishes the text of its data processing agreement as a PDF on its own website. Article 28 of the GDPR requires a written contract with every processor, so this is the document to read and keep.
What we noted when we opened the page: Splunk Data Processing Addendum – US Laws supplements eligible paid customer agreements and excludes trial and similar licenses. No single hosting region is established.
A page that exists does not mean you are covered. Whether the agreement applies to you depends on your plan and on what you accepted, so record the decision yourself in your vendor list.
