Side-by-side comparison of AI visibility scores, market position, and capabilities
Unified AI security and governance platform. 500%+ ARR growth. Raised $58M (Jan 2026). Agentic AI governance for shadow AI discovery. Founded 2023, California.
WitnessAI is an AI security and governance platform founded in 2023 and headquartered in California. The company was built to address a critical enterprise blind spot: as employees and business units adopt AI tools at an accelerating pace — often without IT or security approval — organizations lack the visibility, control, and auditability needed to manage how AI is being used with sensitive data. WitnessAI's founding thesis is that AI governance must be built as dedicated infrastructure, not bolted onto existing security tools, to handle the unique risks introduced by generative and agentic AI systems.\n\nThe platform provides unified discovery of shadow AI usage across an organization, policy enforcement for approved AI tools, real-time monitoring of AI interactions for data leakage and compliance violations, and governance controls for agentic AI workflows that operate autonomously on behalf of users. WitnessAI integrates with enterprise identity providers, SaaS platforms, and security information systems to give CISOs and compliance teams a centralized view of AI risk. Its agentic AI governance capabilities address the emerging challenge of AI agents taking consequential actions within enterprise systems without adequate human oversight.\n\nWitnessAI raised $58 million in January 2026 and has achieved over 500% ARR growth, reflecting the urgency enterprises feel around AI governance as regulatory scrutiny and data breach risks from AI misuse intensify. The company competes in the rapidly forming AI security category alongside Nightfall AI, Securiti, and emerging offerings from established security vendors. Its early mover advantage, purpose-built architecture, and focus on agentic AI governance differentiate it as enterprises move beyond basic acceptable-use policies toward enterprise-grade AI governance frameworks.
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.
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.
