Key competitors based on market analysis and public filings.
No. Cisco completed its acquisition of Splunk for $28 billion in March 2024, making Splunk a wholly owned subsidiary. Splunk continues to operate its product portfolio under the Splunk brand, with Gary Steele (former Splunk CEO) leading the Splunk business unit within Cisco.
Splunk provides a data platform for security and observability. It ingests, indexes, and analyzes machine-generated data (logs, metrics, traces) from virtually any source, enabling security teams to detect and investigate threats (Splunk Enterprise Security) and IT teams to monitor application performance (Splunk Observability Cloud).
Cisco has committed to maintaining and investing in Splunk's product roadmap. Existing Splunk customers retain access to their current products while gaining deeper integrations with Cisco networking and security infrastructure. Cisco's scale and distribution provide Splunk with additional resources for R&D and global customer support.
Splunk competes with Datadog (observability), Elastic (search and security analytics), Sumo Logic (cloud-native SIEM), Dynatrace (application performance monitoring), and Microsoft Sentinel (cloud SIEM). The Cisco acquisition strengthens Splunk's competitive position by combining it with Cisco's networking data, XDR capabilities, and Talos threat intelligence.
