Capability · Framework — observability

Galileo

Galileo positions itself as the reliability layer for enterprise GenAI. Its Evaluate, Observe, and Protect products cover pre-deploy evaluation, production tracing, and runtime guardrails — with an emphasis on hallucination detection, PII, and compliance-ready reporting used at banks and healthcare firms.

Frequently asked questions

Who is Galileo for?

Mid-to-large enterprises deploying LLMs in regulated contexts — finance, healthcare, government — that need auditable guardrails, PII handling, and per-tenant isolation.

Is there a free tier?

Yes, a community plan. Production features such as Protect guardrails and VPC deployment require a paid contract.
