Splunk Agent Observability (formerly Galileo)
AnalyticsEnterpriseVisit Site
An enterprise platform for evaluating, monitoring, and guarding AI agents and LLM applications, including real-time protection against unsafe outputs.
Overview
Galileo is an enterprise-grade evaluation and observability platform with a notable angle: alongside offline evals and production monitoring, it offers runtime guardrails that can detect and block problematic outputs — hallucinations, policy violations — as they happen. It also invests in metrics that work without ground-truth labels, which suits the messy reality of enterprise AI. For large or regulated organizations that need both measured quality and a real-time safety net, it is a serious option. It is squarely an enterprise platform, with the pricing and onboarding that implies. Cisco completed its acquisition of Galileo in May 2026, and Splunk's acquisition page says the product is now Splunk Agent Observability; galileo.ai still serves the standalone site.
