Cisco acquires Galileo to strengthen Splunk's AI observability capabilities

Cisco is acquiring Galileo, an AI observability specialist, to strengthen Splunk's position in the AI monitoring market. The deal is expected to close in July 2026. Galileo provides tools to evaluate AI output quality, detect errors before they reach users, and improve AI agent behaviour in production. The platform monitors hallucinations, bias, security risks and cost metrics across the entire agent development lifecycle, offering real-time observability for multi-agent systems. The acquisition will integrate Galileo into Splunk Observability Cloud, expanding existing AI agent monitoring capabilities. Galileo offers over 20 evaluation metrics including hallucination detection and supports major AI platforms like OpenAI, Anthropic, Azure OpenAI and AWS Bedrock. Cisco and Galileo previously collaborated on Cisco's AGNTCY initiative. Both companies will operate independently until the deal closes.
