Cisco has announced its intent to acquire Galileo Technologies, a fast‑growing AI‑observability startup founded in 2021 by alumni from Google, Uber AI, and Apple. The deal is expected to close in Q4 of Cisco’s FY2026 (ending July).
Why are Cisco acquiring Galileo?
This will help Cisco to further strengthen Splunk’s position as the enterprise standard for monitoring, evaluating, and securing AI agents across the full agent development lifecycle.
This is all about trust – specifically, trust in the upcoming multi‑agent AI systems enrovoenment that is fast emerging for enterprises. Left unmanaged, this multi agent workforce could behave unpredictably, evolve rapidly, and introduce new categories of risk for enterprise organisations.
Who are Galileo?
Galileo was founded in 2021 by alumni from Google, Uber AI, and Apple. The deal is expected to close in Q4 of Cisco’s FY2026 (ending July).
The has quickly become a leader in AI agent observability space, offering:
- Real‑time monitoring of multi‑agent systems and environments.
- Guardrails to detect hallucinations, bias, and unexpected behaviour.
- Evaluation tools for model quality, prompt optimisation, and failure detection .
- A single platform to instrument every stage of the Agent Development Lifecycle (ADLC).
- Wide adoption across startups and Fortune 50 companies, including Comcast, HP, and NTT.
Cisco already has a relationship with Galileo through AGNTCY, an open‑source consortium focused on trustworthy AI agents.
How Cisco will integrate Galileo
Kamal Hathi (SVP & GM, Splunk) has emphasised that Galileo was “purpose‑built to solve one of the hardest problems in AI: trust.” this acquisition will bring strengths to their Splunk portfolio that helps drive AI trust as a first‑class requirement.
Splunk already provides AI‑powered insights, ML features, and a Model Context Protocol (MCP) server. The integration and acquisition of Galileo will bring the following value:
- Improved Real‑time agent visibility
- Behavioural guardrails
- Security‑centric monitoring
- Evaluation tools from development to production
This shifts Splunk from “observability for systems” to observability for AI agents.
Cisco’s Jeetu Patel describes AI agents as “supremely intelligent teenagers with no fear of consequences” – capable of brilliant output and catastrophic mistakes. No imagine them in the wrong hands!
Of course risk with AI includes:
- Hallucinations
- Bias
- Security vulnerabilities
- Unexpected behaviours
- Cost overruns
- Poor end‑user experiences
- Unmanaged agents (those with no human owner).
Cisco will use this aquisition to become the security and trust layer for this new AI workforce for their enterprise clients across both their Splunk and AI defense platforms.
Unification and Expansion
Galileo will gives Splunk a tighter unified platform to instrument every stage of the agent lifecycle:
- Prompt optimisation
- Model selection
- Evaluation
- Production monitoring
- Guardrail enforcement
This is a major differentiator in a market where most tools focus on only one stage.
Why this acquisition matters for the industry
This move signals a broader shift in AI Security.
- AI agents are becoming mainstream in enterprise workflows
- Observability must evolve beyond latency and error rates
- Trust, safety, and behavioural monitoring are now core requirements
- Vendors are racing to build the “AI control plane”
Cisco is positioning Splunk as the platform of record for AI‑agent trust, security, and reliability.
Their acquisition of Galileo is more than a portfolio expansion. It’s a strategic bet on the future of agentic AI – a future where enterprises need deep visibility, strong guardrails, and continuous evaluation to keep AI systems safe, reliable, and cost‑effective.
If we pick apart where Cisco are heading with regards their AI‑trust strategy, then this currently seems to be three main layers:
- Splunk – the visibility layer
Splunk is all about letting IT know what’s happening across systems, apps, and now AI agents. It’s the telemetry engine: logs, metrics, traces. The Galileo aquisition will bring agent behaviour signals. - Galileo – the intelligence layer
Galileo interprets that telemetry.
It evaluates AI agents, detects hallucinations, flags drift, and scores behaviour. It turns raw data into trust insights. These layers will find themselves ingested into both Splunk and AI Defense. - Cisco AI Defense – the control layer
AI Defense uses those insights to enforce identity, policy, and guardrails.
It ensures AI agents behave safely, ethically, and within enterprise rules. The aim is to govern and control all agents through a single pane.
Initial thoughts and reflection
With this aquisition, Cisco are positioning Splunk to become one of the first major platforms to offer a full‑stack AI‑observability solution, and Galileo’s technology clearly fills a gap that traditional monitoring tools simply weren’t designed for. I suspect this will move their AI trust strategy to be simplified into two streams.
- Splunk will be about “What is my AI doing?”
- AI Defense will be the control pane “Is my AI allowed to do that?”
In discussions I have with IT leaders, these are an area of concern that comes up time and and time again. Securing AI agents is a growing need as we move from chat bots to digital assistants to digitial employees. Solution like this will become critical in how enterprises build, deploy, and govern AI agents over the next decade.
