The 10 most powerful companies in enterprise networking 2023

It’s been the year of AI, and expectations are high as enterprise network vendors begin to deliver on the promise of AI networking. Industry players have long been touting the benefits of AI-based operations (AIOps) to help resource-constrained network teams troubleshoot and remediate performance issues, and modern network services such as SD-WAN, 5G and SASE rely on AI to automate some network provisioning and security tasks. Now the release of Microsoft-funded ChatGPT has elevated AI to a C-level imperative, and AI innovation is heating up.

Everyone is jumping on the bandwagon. Nvidia is cranking out GPUs for AI workloads at a record pace, and the hyperscalers are gobbling them up to enhance their AI offerings. Enterprises are racing to embed AI functionality throughout their on-prem and cloud infrastructures. For enterprise network vendors, there’s an opportunity to deliver products and services with an extra helping of generative AI smarts.

On a more fundamental level, those GPUs need to move incredible amounts of data, which creates demand for high-performance interconnects. InfiniBand is commonly used for high-performance computing, but Cisco, Arista, Broadcom, HPE and others have created the Ultra Ethernet Consortium with the goal of making Ethernet the industry standard for AI networking.

The 10 power players on this list are able to deliver highly mature offerings in areas of LAN and WAN infrastructure and services, have a strong security play, and are positioning themselves to take full advantage of the AI boom.

Editor’s note: Our list is ordered, with input from industry watchers, to reflect the companies that are making the biggest power moves and the broadest impact on the network industry. We’ve evaluated these companies not by size but by their influence in the market and their forward momentum. In other words, there is some subjectivity associated with this list.

1. Cisco: Plunks down cash for Splunk

Why they’re here: When you’re the dominant vendor in your market seemingly forever, there might be a tendency to get complacent. Not Cisco under CEO Chuck Robbins. Cisco shook up the networking world with the announcement in September that it plans to buy SIEM stalwart Splunk. Robbins explained that integrating Splunk’s sophisticated data analytics capabilities will bolster Cisco’s AI push. The company reported that it has already taken $500 million in orders for AI Ethernet fabrics, mostly from hyperscalers, and sees the potential for much more. Overall, Cisco continues to run on all cylinders – Ethernet switch revenues increased 55.3% year over year in 2Q23, giving the company a market share of 47.2%. Most recently, Cisco said its backlog is down, and in its fiscal Q1 2024 report, Robbins said the company achieved the strongest Q1 results in its history in both revenue ($14.7 billion) and profitability ($4.5 billion). “After customers implement large amounts of recently shipped product, we expect to see product order growth rates accelerate in the second half of the year,” Robbins stated.

Power moves: Aside from the Splunk splash, Cisco has acquired four other companies focused on security: Armorblox, a threat detection platform; Oort, which does identity management; and Valtix and Lightspin, both in cloud security.

By the numbers: $28 billion. The purchase price for Splunk.

Outlook: Cisco recently released a new security service edge (SSE) offering, a new service designed to protect multicloud workloads and a new high-end firewall. But the focus is on AI. Robbins said: “The acceleration of AI will fundamentally change our world and create new growth drivers for us. Cisco’s ASIC design and scalable fabric for AI position us very well to build out the infrastructure that hyperscalers and others need to build AI ML clusters. We expect Ethernet will lead in connecting AI workloads over the next five years.”

2. Broadcom: Seals the deal for VMware

The company has cobbled together an impressive lineup of products and services, including semiconductors, storage infrastructure, networking (Brocade), network management (CA) and security (Symantec.) The goal of the VMware deal is to provide enterprises with a way to extend on-prem virtualized workloads to multi-cloud environments.

Power moves: Broadcom bought ConnectALL to expand its value stream management (VSM) capabilities. Research firm IDC reports that VSM has become a high priority investment area for enterprises because it helps companies assess the value generated by software development initiatives.

By the numbers: $2 billion. Seeking to reassure VMware customers anxious about what will happen after the acquisition, Broadcom CEO Hock Tan pledged that the company will spend $2 billion a year to accelerate research and development for VMware products and services.

Outlook: Tan has outlined a clear strategy for Broadcom going forward. He said: “We will invest in extending VMware’s software stack to run and manage workloads across private and public clouds, which means any enterprise can run application workloads easily, securely and seamlessly on-prem, or in any cloud platform they prefer.” The increased investment will also be focused on building VMware’s professional services. Gaining acquisition approval from regulators in China was a significant hurdle for Broadcom to clear; now it needs to absorb VMware without losing customers to competitors that are eagerly offering VMware migration assistance.

3. Arista: Hitting on Ullal cylinders
