Splunkd is the core server daemon of the Splunk platform, a data analytics and monitoring solution developed by Splunk Inc. (now part of Cisco). When used for web analytics, Splunk can collect visitor data through JavaScript tracking tags or server-side log ingestion. The Splunk App for Web Analytics analyses weblogs without injecting client-side JavaScript. Splunk sets cookies for session management and may use web beacons for advertising effectiveness tracking. The platform processes data in the US and maintains GDPR compliance through a Data Processing Agreement. Splunk offers both cloud-hosted and self-hosted deployment options.
Splunkd is the core server daemon of the Splunk platform, an enterprise-grade data analytics and monitoring solution now owned by Cisco. In web contexts, Splunk is used to ingest, index, and analyse web server logs and user interaction data to provide real-time visibility into website performance, visitor behaviour, and security events.
Splunk offers two primary approaches to web analytics. The Splunk App for Web Analytics processes web server logs directly, analysing access patterns, referrers, visitor counts, and page performance without injecting JavaScript into web pages. This server-side approach minimises client-side tracking. Alternatively, Splunk can collect data through JavaScript tracking tags and web beacons embedded in web pages, similar to traditional analytics platforms.
The platform also includes AppDynamics (acquired by Cisco), which provides Browser Real User Monitoring with cookie consent management capabilities. This allows website owners to correlate business transactions with end-user monitoring while respecting cookie consent requirements.
Splunk uses browser cookies, web beacons, tags, and other web analytics technologies when visitors interact with Splunk-powered websites. Cookies track the efficiency of advertising campaigns and marketing communications. When using the server-side log analysis approach, no client-side cookies are required for analytics functionality, making it a cookieless option for privacy-conscious deployments.
Splunk operates as a data processor under GDPR when handling personal data on behalf of customers. The company Data Processing Agreement meets GDPR requirements for service providers. Splunk collects IP addresses and online identifiers that constitute personal data under GDPR. The platform is designed to provide analytics functionality without requiring identifying information like names or email addresses.
Splunk Inc. is headquartered in San Francisco, USA, and is now part of Cisco Systems. Data processing occurs primarily in the United States for cloud deployments. The company participates in the EU-US Data Privacy Framework. Self-hosted deployments allow organisations to keep all data within their own infrastructure and jurisdiction.

Splunk offers both cloud-hosted (Splunk Cloud) and self-hosted (Splunk Enterprise) deployment models. For organisations with strict data residency requirements, self-hosted deployments keep all data on premises. Cloud deployments benefit from managed infrastructure but involve data transfer to Splunk data centres.
Websites using Splunkd must obtain user consent under GDPR regulations.
DPIA considerations
Splunk processes potentially large volumes of personal data including IP addresses, browser fingerprints, and user behaviour patterns. A DPIA should evaluate the scope of data ingestion, retention periods, access controls, and whether the deployment is cloud-hosted (data in US) or self-hosted. For cloud deployments, assess cross-border data transfer mechanisms and Splunk DPA terms. Consider the breadth of data correlation capabilities Splunk offers.

Yes. The Splunk App for Web Analytics processes server-side web logs without injecting JavaScript or setting cookies. This approach analyses access patterns, referrers, and visitor counts entirely from server logs.
Splunk can collect IP addresses, browser types, access times, pages viewed, referrer URLs, and user interaction patterns. The exact data scope depends on the deployment configuration and whether client-side or server-side tracking is used.
Splunk processes data on behalf of customers and does not share customer data with third parties for independent use. Data sharing is governed by the customer Data Processing Agreement and Splunk privacy policy.
When Splunk uses client-side cookies or JavaScript tags for web analytics, consent is required under GDPR and the ePrivacy Directive. Server-side log analysis without cookies may be processed under legitimate interest, but this should be evaluated case by case.
