Cisco Acquires Galileo Technologies to Embed AI Agent Monitoring in Splunk Observability Platform

Cisco announced its intent to acquire Galileo Technologies, an AI observability startup founded in 2021 by engineers from Google, Uber AI, and Apple, according to a blog post from Kamal Hathi, Cisco’s SVP and GM of Splunk. The deal, expected to close in Q4 of Cisco’s fiscal year 2026 (around July), will embed Galileo’s agent monitoring and guardrail technology directly into Splunk Observability Cloud. Financial terms were not disclosed.

What Galileo Does

Galileo’s platform provides real-time observability for multi-agent AI systems across the full agent development lifecycle. That includes hallucination detection, bias flagging, performance monitoring, and enforceable guardrails in production. The company has raised $68.1 million in total funding, with a $45 million Series B led by Scale Venture Partners in 2024, according to CRN. Customers include Comcast, HP, and NTT.

Hathi framed the acquisition around the trust gap in agentic AI. “These issues can ultimately lead to decreased customer trust, poor end-user experiences, and increased costs,” he wrote. “Teams need visibility across the AI stack beyond signals like latency and errors. Observability must evaluate issues like hallucinations and bias, security metrics to detect and mitigate business risks, and track cost and usage metrics to ensure clear ROI.”

Two Agent Acquisitions in One Week

This is Cisco’s second agent-infrastructure deal in the same week. The company is simultaneously in talks to acquire Astrix Security for an estimated $250 to $350 million to bring agent identity and access governance into its portfolio, as SiliconANGLE reported. Together, the two acquisitions would give Cisco a full enterprise agent governance stack: monitor agent behavior (Galileo via Splunk) and control agent identity and access (Astrix).

The companies have history. Cisco and Galileo were both members of AGNTCY, a consortium established to create open-source specifications for trustworthy AI agents, as SiliconANGLE noted.

Cisco’s Agent Security Push

The Galileo acquisition fits a pattern Cisco has been building since RSAC 2026 in March, where the company unveiled Duo Agentic Identity for discovering and monitoring enterprise AI agents and expanded its AI Defense platform to cover agent workloads. Cisco President Jeetu Patel compared AI agents to teenagers at the conference: “They’re superbly and supremely intelligent, but they have no fear of consequences,” according to SiliconANGLE.

The velocity of Cisco’s moves suggests the company is betting that agent governance, not agent building, will be the dominant enterprise market. While OpenAI, Anthropic, and Google compete to build the smartest agents, Cisco is positioning to be the company that monitors, secures, and governs all of them.
