Galileo is an AI observability and eval engineering platform built to help organizations measure, protect, and improve AI applications and agents across the full development lifecycle. Now part of Cisco, Galileo is positioned around the idea that teams should not only monitor AI failures, but prevent them with production-ready guardrails. The platform helps teams capture ground truth from synthetic data, development workflows, live production traffic, and subject matter expert annotations. Galileo provides more than 20 out-of-the-box evaluations for RAG systems, agents, safety, security, and custom use cases. Its eval engineering workflow helps teams create accurate evaluators that reflect their own domain expertise instead of relying only on generic metrics. Galileo can auto-tune metrics from live feedback so evaluations become better aligned with real environments. The platform’s Luna models distill expensive LLM-as-judge evaluators into compact models that can run across production traffic at lower cost and lower latency. Galileo’s insights engine analyzes millions of signals across models, prompts, functions, context, datasets, traces, and MCP server activity to identify failure modes and recommend fixes. Teams can use these insights to debug agent behavior, improve prompts, adjust tools, detect hallucinations, and strengthen AI reliability. Galileo supports the eval-to-guardrail lifecycle, where pre-production tests become production policies that can block harmful responses, control tool access, and guide escalation paths. By combining AI observability, evals, ground-truth datasets, Luna guardrail models, agent reliability workflows, safety controls, deployment flexibility, and production monitoring, Galileo helps enterprises ship AI systems with more confidence.

Silmaril represents a groundbreaking defense strategy against prompt injection, designed to autonomously repair itself in order to protect AI systems from complex, layered threats that traditional defenses often fail to address. Unlike standard techniques that simply filter out harmful inputs, it envelops inference requests, rigorously analyzing whether the series of actions could lead to adverse outcomes. Utilizing a multihead classifier, Silmaril assesses user motivations, application contexts, and execution states in parallel, enabling it to detect indirect injections, prolonged attack patterns, context alterations, and tool misuse before they can inflict damage. To bolster its protective features, Silmaril employs autonomous threat-hunting agents that navigate through systems, uncover vulnerabilities, and generate synthetic training data from real attack scenarios. This intelligence not only aids in automatic model retraining, allowing for the implementation of upgraded defenses in under an hour, but also ensures the distribution of anonymized protective strategies across all operational instances. Furthermore, this forward-thinking methodology guarantees that the system can maintain its resilience against new threats, continuously adapting to the shifting challenges in the cybersecurity landscape. By consistently evolving, Silmaril ultimately fortifies the security framework surrounding AI technology.
