Illumio vs Splunk
Side-by-side comparison of AI visibility scores, market position, and capabilities
Illumio is a zero trust segmentation platform that maps application dependencies and enforces workload-level policy to contain breaches across cloud, data center, and endpoints.
About
Illumio is a cybersecurity company headquartered in Sunnyvale, California that pioneered the zero trust segmentation category — providing visibility into application communication flows and enforcing workload-level micro-segmentation policies across hybrid cloud, data center, and endpoint environments to limit the lateral movement that makes ransomware and supply chain attacks so damaging. Founded in 2013, Illumio raised $225 million in a 2021 Series F that valued the company at $2.75 billion, reflecting enterprise demand for segmentation technology as a breach containment control independent of network perimeter tools. The company's core thesis is that breaches are inevitable and that security programs must invest in preventing attackers who have entered the environment from moving freely to reach high-value targets.
Data platform for security and observability acquired by Cisco for $28B in March 2024. Used by 90 of Fortune 100; 7,500+ enterprise customers globally; flagship SIEM and Splunk SOAR power enterprise security operations centers.
About
Splunk is a data platform for security and observability founded in 2003 in San Francisco, built on the idea that machine-generated data — logs, events, metrics, traces — contains the intelligence organizations need to detect threats, investigate incidents, and ensure digital systems stay available. The company's core technology indexes and searches massive volumes of machine data in real time, enabling security and IT operations teams to answer complex questions across their entire data estate without predefined schemas.\n\nSplunk's flagship product is its SIEM (Security Information and Event Management) platform, used by 90 of the Fortune 100 to detect and respond to security threats. Its broader portfolio includes Splunk Observability Cloud for infrastructure monitoring, Splunk SOAR for security orchestration and automated response, and Splunk IT Service Intelligence for IT operations. The platform's schema-on-read approach and SPL query language give analysts flexibility to investigate novel threats and operational issues that structured databases cannot accommodate.\n\nSplunk was acquired by Cisco for $28B in March 2024, one of the largest cybersecurity acquisitions in history, and has been integrated into Cisco's AI-driven security portfolio. The combination of Cisco's network telemetry and global customer relationships with Splunk's data analytics depth creates a powerful full-stack security and observability offering. Under Cisco, Splunk is adding AI-native features — including AI Assistant for SPL and automated threat detection — to maintain its leadership position as the SIEM market evolves toward AI-augmented security operations.
