Cisco’s acquisition of Splunk signals a new era for AI-enabled cybersecurity and observability platforms

Cisco completes a $28bn deal to integrate Splunk’s security and monitoring software into its broader enterprise resilience strategy, heightening the role of AI and data analytics in cybersecurity infrastructure.

Splunk may no longer trade as a standalone listed company, but its software remains a useful case study in how cybersecurity and observability tools are being folded into larger platform strategies. Cisco said the acquisition was designed to combine Splunk’s security and monitoring software with its own network capabilities, creating a more connected way for organisations to protect operations and manage data across complex systems.

Cisco completed the $28bn deal in March 2024 and has since framed Splunk as part of a broader push into AI, data analytics and enterprise resilience. In Cisco’s telling, the combined business is intended to give customers deeper visibility across their digital estate, while also improving security in an environment increasingly shaped by cloud adoption and artificial intelligence.

That logic explains why Splunk continues to attract attention even after its delisting. The platform was built around real-time analysis of machine data, making it useful for threat detection, incident response, application monitoring and infrastructure management. Cisco has also highlighted integrated observability offerings and, more recently, AI-related capabilities showcased at industry events, including agentic AI features aimed at helping enterprises make better use of operational data.

For investors, the name still matters because it sits at the centre of a larger trend: big technology groups buying specialist software to strengthen their security and observability stacks. Cisco’s own marketing suggests it sees Splunk as a building block for a more AI-enabled product portfolio, and the addition of Galileo Technologies in 2026 further underlined that ambition by expanding Cisco’s AI observability reach. The main question now is not whether Splunk can stand alone, but how much strategic value Cisco can extract from it inside the wider business.
