Cisco entered 2025 with a credible turnaround opportunity, but not an easy one. Its traditional networking business was under pressure, the company was absorbing the $28 billion Splunk acquisition, and customers were shifting spending toward artificial intelligence, cybersecurity, cloud operations, and software.
By the end of Cisco’s fiscal 2025, the picture had improved materially. Cisco reported $56.7 billion in revenue, up 5% year over year, and said AI-infrastructure orders from web-scale customers exceeded $2 billion. But those figures do not prove that Cisco’s largest strategic problems are solved. Orders are not the same as recognized revenue, recurring profit, or durable market share.
The better investor conclusion is that Cisco changed the question from “Can it find growth?” to “Can it turn an AI-driven rebound, Splunk integration, and security push into repeatable platform growth?”
Why Cisco needed a reset
Cisco remains one of the most important companies in enterprise networking, but its scale also exposes it to mature-market pressures. Traditional enterprise networking spending has become more budget-constrained, while customers increasingly prioritize AI infrastructure, cybersecurity, cloud management, and software-based services.

The pressure was visible before 2025. The original January 2025 analysis reported that Cisco’s networking revenue fell 23% year over year in its first fiscal quarter of 2025. Cisco’s fiscal year does not match the calendar year, so this figure should not be read as a full-year 2025 result. It did, however, illustrate the strategic problem: Cisco needed to defend its installed base while finding growth in faster-moving markets.
Cisco’s broad portfolio was both an advantage and a liability. Products spanning routing, switching, wireless, collaboration, security, observability, application performance, and cloud management created cross-selling opportunities. They also made the company difficult for customers to understand, buy from, and manage.
The 2025 agenda therefore had several connected parts:
- Revive core networking, including campus, branch, routing, and data-center products.
- Build a credible position in AI infrastructure.
- Integrate Splunk rather than operating it as an expensive standalone acquisition.
- Make networking, security, and observability function more like a platform.
- Simplify product decisions, licensing, management, and the go-to-market structure.
What Cisco actually achieved in fiscal 2025
Cisco’s reported results were stronger than the cautious outlook at the start of the year suggested:

Pick the symptom - the matching free tool is one click away.
| Measure | Fiscal 2025 result | Why it matters |
|---|---|---|
| Revenue | $56.7 billion, up 5% year over year | Shows a return to overall growth, although it does not identify which businesses drove it. |
| Fourth-quarter revenue | $14.7 billion, up 8% | Indicates stronger momentum at the end of the fiscal year. |
| AI-infrastructure orders | More than $2 billion from web-scale customers | More than twice Cisco’s original $1 billion target, according to the company. |
| Fourth-quarter AI orders | More than $800 million | Shows increasing order activity, but orders can be delayed or changed before revenue is recognized. |
| Fourth-quarter product orders | Up 7% year over year | Suggests broader product demand, not merely software or acquisition-related growth. |
| Splunk new logos | Up 14% year over year in the fourth quarter | Provides evidence of cross-selling and commercial progress, based on Cisco management’s report. |
Cisco also said recurring revenue represented more than half of total revenue. That is strategically important, but investors should not automatically equate “recurring revenue” with pure subscription revenue. Cisco’s definition can include different recurring sources, so the quality, duration, margins, and renewal rates of that revenue matter.
The fiscal 2025 scorecard supports a measured conclusion: Cisco generated meaningful momentum, especially in AI infrastructure and product orders. It does not yet demonstrate that every part of the portfolio has returned to durable growth.
Splunk: strategic asset or execution burden?
Cisco completed its $28 billion Splunk acquisition in March 2024. The strategic logic was clear. Splunk brought security analytics, observability, application visibility, and a larger software and recurring-revenue base. Cisco brought network telemetry, security products, infrastructure customers, threat intelligence, and a substantial enterprise sales channel.
If integrated successfully, the combination could help a customer answer a connected set of questions:
Rank #2
- Aggregate Throughput: 100 Mbps to 300 Mbps
- Total onboard WAN or LAN 10/100/1000 ports: 3
- RJ-45-based ports: 2
- SFP-based ports: 2
- Enhanced service-module (SM-X) slot: 1
- What is happening across the network, applications, cloud, and endpoints?
- Is an operational problem actually a security incident?
- Which users, devices, workloads, or services are affected?
- Can the organization automatically contain the threat or remediate the failure?
The commercial opportunity is to sell more Splunk to Cisco customers and more Cisco infrastructure and security to Splunk customers. Cisco reported that Splunk new logos rose 14% year over year in the fourth quarter of fiscal 2025, attributing the increase partly to cross-selling and joint innovation. That is encouraging evidence, but it remains a management-reported indicator rather than independent proof that the acquisition has fully delivered its expected synergies.
The integration risks are substantial:
- Overlapping products: Customers may struggle to understand how Splunk, Cisco XDR, Secure Network Analytics, ThousandEyes, AppDynamics, and other tools fit together.
- Packaging confusion: Bundling can simplify procurement for some customers but make licensing harder for others.
- Technical fragmentation: A common sales message is not the same as a shared data model, identity layer, policy engine, or management console.
- Customer resistance: Splunk users may not want to adopt Cisco infrastructure, while Cisco customers may already use competing security or observability products.
For investors, the key test is not simply whether Cisco cross-sells Splunk. It is whether customers obtain measurable benefits such as faster incident investigation, fewer management tools, lower operating costs, and stronger retention.
Platformization must reduce complexity
Cisco’s Networking Cloud and Security Cloud strategies aim to connect networking, security, observability, identity, policy, and automation. The portfolio includes assets such as Splunk, ThousandEyes, Cisco XDR, Secure Access, Meraki, Intersight, and Nexus Dashboard.
Platformization can create real value when it delivers:

- Shared identity and policy across campus, branch, cloud, and data-center environments.
- Telemetry that security and operations teams can use together.
- Automated detection, remediation, and rollback.
- Simpler purchasing and fewer disconnected management systems.
It becomes mainly a branding exercise when products retain separate data stores, consoles, contracts, workflows, and support models. Cisco’s breadth is a competitive advantage only if it reduces the customer’s operational burden. Otherwise, best-of-breed specialists may remain more attractive even when they require integrations.
Leadership and restructuring
In August 2024, Cisco announced a restructuring involving a planned 7% global workforce reduction. Jeetu Patel became executive vice president and chief product officer, with responsibility for bringing greater coherence to Cisco’s portfolio. Cisco also planned to reorganize networking, security, and collaboration businesses.
The intended benefit was faster decision-making and closer alignment with high-growth markets. The challenge is that “acting like a startup” is difficult for a company of Cisco’s size. Restructuring can improve accountability, but it can also affect engineering continuity, customer support, partner relationships, and employee morale. The workforce reduction was announced in 2024 and should not be treated as evidence that all reductions occurred during 2025.
Patel’s central execution test was to make the portfolio easier to understand without weakening the enterprise relationships and support infrastructure that helped Cisco build its installed base.

AI is three different opportunities, not one
Cisco’s AI strategy spans at least three markets, each with different buyers, competitors, sales cycles, and economics:
- Web-scale AI training infrastructure: High-performance data-center networking, optics, switching, routing, and related infrastructure for hyperscalers and large cloud customers.
- AI cluster networking: Ethernet fabrics designed to move large volumes of data between GPUs and other components with appropriate latency, congestion control, and telemetry.
- Enterprise and private AI: Infrastructure and security for organizations running inference, sovereign-cloud workloads, or private AI systems closer to their own data.
Cisco’s relevant assets include Silicon One, Nexus 9000 switches, Cisco 8000 routers, UCS servers, AI Pods, Nexus Hyperfabric AI, Intersight, Acacia optical products, Isovalent Kubernetes networking, Splunk Observability Cloud, AI Defense, and Hypershield. Cisco also announced AI-ready data-center offerings and expanded work with NVIDIA, including products associated with NVIDIA’s Spectrum-X architecture.
In fiscal 2025, Cisco reported more than $2 billion in AI-infrastructure orders from web-scale customers, including more than $800 million in the fourth quarter. This was a significant commercial achievement. The qualification is essential: these are orders, not recognized revenue, installed-base adoption, or proof of long-term profitability.
The bull case
AI clusters need high-bandwidth Ethernet, congestion management, low-latency fabrics, optical connectivity, telemetry, secure data movement, and operational automation. Cisco can combine those capabilities with an existing enterprise customer base, security products, and observability tools. Its installed relationships may become especially valuable as AI moves beyond a small number of hyperscalers into enterprises, telecommunications providers, and regulated or sovereign environments.
The bear case
Hyperscalers often buy directly from specialized suppliers and may design much of their own infrastructure. Arista, NVIDIA, Broadcom-based switching ecosystems, and other focused vendors compete intensely for the economics of AI data-center networking. Cisco’s AI products could also be sold mainly as components, limiting differentiation and pricing power.
AI networking may ultimately be a narrower opportunity than the marketing suggests if enterprise AI adoption remains slow or if most spending is concentrated among a small number of web-scale customers. A strong order year is valuable, but investors should watch conversion, customer concentration, margins, repeat orders, and demand after major AI infrastructure cycles normalize.
Security may be the more durable growth opportunity
Security could matter more strategically than AI networking because security spending applies across the campus, branch, data center, cloud, and operational environment. It is not immune to budget pressure, but organizations generally cannot defer risk indefinitely.
Cisco’s 2025 security strategy included Hypershield, Secure Access, Universal ZTNA, Cisco XDR, Hybrid Mesh Firewall, AI Defense, Talos threat intelligence, and Splunk Enterprise Security. At Cisco Live in June 2025, the company announced expanded firewall, zero-trust, and Splunk integration capabilities intended to fuse security more closely with the network.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsRank #4
- Enjoy the benefits of Wireless-N in your home--ideal for wireless Internet usage and home office productivity
- Connect your computers, wireless printers, smartphones, and other wireless devices at up to 300 Mbps of transfer speed
- Use four Fast Ethernet (10/100 Mbps) ports to directly connect wired devices
The thesis is that the network can provide context and enforcement at the point where users, devices, workloads, and applications connect. That could improve segmentation, threat detection, and response. Splunk can add broad security analytics, while Talos contributes threat intelligence.
The risk is that network-embedded security can also increase policy complexity and vendor dependence. Cisco must show that its integrated approach produces measurable operational improvements rather than simply adding more controls to an already complicated environment. Palo Alto Networks, Fortinet, CrowdStrike, Microsoft, Broadcom/Symantec, and specialist security providers remain formidable competitors.
Campus, branch, and Meraki still matter
Cisco cannot depend on hyperscale AI customers to repair every weakness in its much larger installed-base businesses. Campus switching, wireless, routing, collaboration, branch security, SD-WAN, and digital experience remain central to the company’s enterprise position.
Meraki offers a simpler cloud-managed model, while Catalyst products address larger and more complex enterprise environments. Cisco’s challenge is to modernize both without forcing customers to choose between simplicity and scale.
HPE Aruba, Juniper Mist, Extreme Networks, Nile, and Meter compete in different parts of campus and branch networking. Juniper Mist in particular illustrates the appeal of cloud management and AI-assisted operations. Cisco must make deployment, policy, monitoring, and troubleshooting easier if it wants to defend its installed base.
A successful campus strategy would connect Wi-Fi, switching, SD-WAN, secure access, branch security, and digital experience monitoring in a way customers can actually operate. Merely adding AI labels to existing tools will not be enough.

Security
Palo Alto Networks and Fortinet are major network-security specialists. CrowdStrike, Microsoft, and Broadcom/Symantec compete across endpoint, identity, cloud, and security operations. Cisco’s advantage is integration with the network and enterprise installed base; specialists may retain advantages in focused detection, response, or ease of adoption.
Observability
Datadog, Dynatrace, Elastic, and other application- and cloud-centric providers compete with Splunk and Cisco’s observability products. Cisco must prove that network-centric context is valuable enough to win budget from tools already embedded in development and operations workflows.
A practical investor scorecard
Investors evaluating Cisco after fiscal 2025 should track the following rather than relying on broad claims about AI or platforms:
- Core networking stabilization: Is growth continuing in campus, branch, routing, and data-center products independently of Splunk?
- AI revenue quality: Are reported orders converting into revenue, repeat deployments, attractive margins, and diversified customer demand?
- Splunk integration: Are combined Cisco-Splunk solutions producing measurable cross-sell, retention, and usage benefits?
- Security differentiation: Does network-embedded security reduce investigation time, improve response, or lower operating costs compared with specialist alternatives?
- Portfolio simplicity: Are customers facing fewer consoles, clearer licensing, and more coherent consumption models?
- Competitive relevance: Can Cisco defend campus and branch share while remaining credible in AI data-center networking?
- Recurring-revenue quality: Is recurring revenue growing with healthy renewals and margins, rather than simply reflecting bundled or support-related contracts?
What could still go wrong
- AI orders could be delayed, resized, concentrated among a few customers, or less profitable than expected.
- Splunk could remain commercially bundled but technically fragmented.
- Security integration could create policy conflicts and troubleshooting challenges.
- AI demand could shift from training toward inference, requiring different products and customer relationships.
- Cisco could lose campus and branch momentum while reporting strong AI growth.
- Restructuring could accelerate decisions but damage engineering continuity or partner confidence.
- Recurring revenue could grow without producing the margin expansion investors expect from a software platform.
Enterprise buyers should also remember that Cisco’s AI infrastructure, security, and Splunk offerings are generally quote-based. Pricing depends on hardware configuration, data volumes, users, features, support, deployment, geography, and channel terms. Smaller organizations without substantial data-center workloads or Cisco expertise may find the broader stack unnecessarily complex.
Verdict
Cisco made meaningful progress during fiscal 2025. Revenue returned to growth, AI-infrastructure orders exceeded expectations, product orders improved, security offerings expanded, and Cisco reported evidence of Splunk cross-selling.
That progress does not invalidate the original warning that Cisco had “lots of hard work ahead.” It confirms that the work had begun. Cisco still needs to prove that AI orders become durable, diversified revenue; that Splunk becomes a deeply integrated platform; that security products can compete with specialists; and that customers experience less complexity rather than simply a larger Cisco umbrella.
For investors, the most balanced view is neither “Cisco is declining” nor “AI will save Cisco.” The company has a stronger growth narrative than it did at the start of 2025, but the next phase will be judged on repeatability, margins, customer outcomes, and execution after the initial AI spending surge.
