Galileo is an AI observability and evaluation engineering platform that helps users build AI apps, and which is based in California. AI observability covers the monitoring, troubleshooting and understanding of AI systems, such as large language models and AI agents.

The acquisition would support Cisco’s AI agent monitoring capabilities, including its agentic AI platform Splunk Observability.

Cisco said that the acquisition is expected to close in in the fourth quarter of its 2026 fiscal year, and is for an undisclosed amount.

In a blog post about the acquisition, Kamal Hathi, senior vice-president and general manager at Splunk, a Cisco company, said: “AI agents are not just productivity solutions but are crucial digital coworkers that play critical roles alongside human teams.  

“To unlock the full potential of AI, it’s essential to help ensure a foundation of transparency and accuracy. That is why we are thrilled to announce Cisco’s intent to acquire Galileo Technologies.”
