About Galileo

Galileo is an evaluation, observability and guardrails platform for generative AI applications and AI agents. It has been owned by Cisco since May 2026: Cisco announced its intent to acquire Galileo Technologies, Inc. on April 9, 2026, and said on May 22, 2026 that the acquisition was complete. Terms weren't disclosed. Galileo is now part of Splunk, a Cisco company, and its documentation says that as of August 7, 2026 "Galileo is now Splunk Agent Observability." Customers who onboarded before that date use Galileo's documentation; later customers use Splunk's. galileo.ai's pricing page now redirects to Splunk's pricing page. Galileo was founded in 2021 by Vikram Chatterji (CEO), formerly of Google AI, Atindriyo Sanyal, formerly of Apple and Uber AI, and Yash Sheth, formerly of Google, and was based in San Francisco. Before the acquisition it raised $68 million, most recently a $45 million Series B led by Scale Venture Partners in October 2024; it then said six Fortune 50 companies, including Comcast and Twilio, were customers. The platform logs traces and spans from agent frameworks (LangChain and LangGraph, CrewAI, the OpenAI Agents SDK, Strands Agents, the Vercel AI SDK, and any OpenTelemetry or OpenInference source) and scores them with metrics such as context adherence, correctness, tool selection quality, action completion, toxicity, PII, prompt injection and sexism/bias. Many metrics run on Luna-2, Galileo's small evaluation models, which require an enterprise plan; Galileo says they cut production monitoring costs by up to 97% with latency under 200 ms. Signals (January 2026) detects failure patterns across production traces and can turn them into custom metrics. Agent Control, an open-source (Apache 2.0) control plane released in March 2026, applies central policies to agents (deny, steer, warn, log or allow) using Luna, NVIDIA NeMo, Amazon Bedrock or custom evaluators. It replaced Galileo's older Protect guardrails, which were deprecated in June 2026. Under Splunk, Galileo's technology is being added to the AI Agent Monitoring feature of Splunk Observability. In June 2026 Splunk described Splunk Agent Observability as a new on-premises offering powered by Galileo; in October 2026 it said the product had started rolling out in September 2026 on premises, in Cisco Cloud Control and in Splunk Observability Cloud, and its pricing page lists it for Observability Cloud and self-hosted deployments. **AI compliance coverage** Galileo doesn't document support for the EU AI Act, the NIST AI RMF or ISO 42001. Its trust page says it has a SOC 2 Type II report, provides HIPAA-compliant infrastructure and can sign business associate agreements (BAAs). What it offers a compliance program is evidence of how models and agents behave (evaluation scores, traces and guardrail decisions), not framework controls or an AI inventory. **Who it's for** Engineering teams building LLM applications and agents that want evaluation, production monitoring and runtime guardrails in one tool. New customers now buy through Splunk, so it fits Splunk Observability customers most naturally.

Galileo features

Capabilities Galileo markets publicly. Inclusion means the feature is documented on the vendor's site — not that it's best-in-class. Last checked October 15, 2026.

LLM Evaluation

Systematic testing of LLM outputs for correctness, relevance, safety, and consistency using automated scorers, rubrics, or human review.

LLM Observability

Logging, tracing, and metrics for LLM applications in production — latency, cost, quality, and error rates across traces and users.

Agent Tracing

End-to-end visibility into multi-step LLM agent runs: tool calls, intermediate reasoning, token usage, latency, and errors at each step.

Hallucination Detection

Automated scoring of LLM outputs for factual accuracy and groundedness, typically via retrieval-backed verification or reference comparison.

LLM Guardrails

Runtime input/output filtering for LLMs — PII redaction, toxicity blocking, prompt injection defense, policy enforcement.

Prompt Injection Defense

Detection and mitigation of malicious prompts intended to bypass system instructions or exfiltrate data.

Data Leakage Prevention

Inspection of LLM outputs to block PII, secrets, and regulated data from leaving the boundary.

Policy Enforcement

Mechanism for applying organizational and regulatory policies to AI usage at runtime.

Pros and cons of Galileo

Pros

  • Agent-specific metrics (tool selection quality, action completion, context adherence) alongside safety metrics for PII, prompt injection and toxicity, plus custom metrics.
  • Luna-2 small evaluation models are built to score all production traffic; Galileo says they cut monitoring costs by up to 97% with latency under 200 ms.
  • Agent Control is open source (Apache 2.0) and works with other guardrail providers such as NVIDIA NeMo and Amazon Bedrock.
  • Owned by Cisco and part of Splunk since May 2026; Galileo has a SOC 2 Type II report and can sign BAAs for healthcare customers.

Cons

  • Ownership change: new customers buy Splunk Agent Observability through Splunk, and Cisco and Splunk haven't published what happens to existing Galileo plans and contracts.
  • Pricing moved to Splunk: Galileo's own plans are gone, and Splunk's published entry price is billed annually per 1.2 million spans, so small teams can no longer start on a monthly Pro plan.
  • Luna-2 metrics, which power its low-cost evaluations and guardrails, require an enterprise plan.
  • No documented support for the EU AI Act, NIST AI RMF or ISO 42001, and no AI inventory or governance workflow.
  • Its G2 listing mixes in reviews of unrelated products named Galileo, so there is no reliable third-party rating.
