AI Security Pivot Places Cisco Systems Stock (CSCO) in Pole Position

In This Article:

Cisco Systems (CSCO) shares remained relatively flat despite the company surpassing expectations in its latest quarterly results published last week. The technology leader delivered both revenue and earnings beats, driven by strong performance in its security and observability segments.

These results underscore Cisco’s continued transition from legacy networking hardware to a more diversified, higher-margin software and services portfolio. A strategic pivot toward AI-powered security solutions seems to be paying off, although the market has yet to realize it. With an expanding product mix, upwardly revised guidance, and multiple analyst upgrades, I maintain a long-term bullish outlook on Cisco.

Splunk Powers Security Transformation

Cisco’s Security segment has emerged as a key growth driver following its strategic shift toward AI-powered cybersecurity solutions. Revenue in the segment surged 54% year-over-year to $2 billion last quarter.

Historically challenged by competition from pure-play cybersecurity firms like CrowdStrike (CRWD), Cisco has significantly strengthened its position through its $28 billion acquisition of Splunk. This acquisition has accelerated growth and enabled the launch of new products such as Hypershield and AI Defense—AI-driven solutions designed to secure data centers and cloud environments. Notably, both products have already been adopted by Fortune 100 companies.

Splunk has also revitalized Cisco’s Observability segment, which saw a 24% revenue increase last quarter. Before the acquisition, Cisco’s organic observability business grew by 3–4% annually. Integrating Splunk’s capabilities has created a more compelling offering for enterprises deploying AI workloads, delivering enhanced visibility and intelligence.

Together, the Security and Observability segments are now central to Cisco’s broader AI transformation strategy. For organizations seeking comprehensive visibility, protection, and data insight, Cisco is positioning itself as a full-spectrum solution provider. Reflecting this momentum, the company expects to generate ~$56.6 billion next quarter.

Execution Risks and Competitive Challenges

That said, Cisco’s $28 billion acquisition of Splunk was a significant investment, and while initial results are encouraging, the real test lies ahead as integration efforts deepen. Ideally, long-term growth is driven by organic innovation rather than large-scale acquisitions. Cisco’s track record in this area has been mixed—prior acquisitions such as AppDynamics and WebEx have delivered uneven outcomes over time.
