About the company

Cisco makes the switches and routers that connect offices, data centers, and cloud services, and it also sells cybersecurity tools and Webex video meetings to businesses and governments. It was one of the first companies to sell routers that let different kinds of computer networks exchange data, and in 2000 it briefly became the world's most valuable company. Customers run its network gear, from Wi-Fi access points to AI data center systems, with Cisco software that sets up and secures the network, while its Splunk unit searches computer logs to catch outages and attacks. Cisco earns money from hardware sales, software subscriptions, and support contracts. It was founded in 1984 and is based in San Jose, California.

Simplify's Take

What believers are saying

  • Cloud giants fuel growth: they ordered $9.3 billion of Cisco's AI gear in the year to July 2026, up 4.5-fold.
  • Stock awards gained value: Cisco shares rose 63% in the year to October 2026, four times the S&P 500's 15%.
  • Signed deals steady the business: Cisco had $46.7 billion of contracted sales still to deliver in July 2026, up 7%.

What critics are saying

  • Record sales didn't stop layoffs: Cisco cut nearly 4,000 jobs, just under 5% of staff, in May 2026.
  • Rivals lead in data center switches: in the June 2026 quarter, Nvidia held 20.4%, Arista 18.7% and Cisco 18.2%.
  • Hardware-heavy AI growth squeezes profit: Cisco's gross margin fell to 66.3% from 68.4% in the July 2026 quarter.

What makes Cisco unique

  • Cisco still sells the most network switches: it took 28.7% of worldwide switch sales in the June 2026 quarter.
  • Cisco designs its own networking chips: Microsoft and Alibaba signed on early for its Silicon One P200, launched October 2025.
  • Cisco trains future network engineers: its Networking Academy has taught over 28 million learners in 195 countries since 1997.

Cisco and NVIDIA back 400G USFP optical standard to quadruple AI data centre bandwidth density

Cisco Systems and NVIDIA have announced a collaboration to bring 400G optical technology to AI data centres. The partners plan to commercialise a new ultra small form factor pluggable (USFP) standard designed to quadruple bandwidth density. The companies aim to build an open hardware ecosystem with other optical and networking vendors, including TE Connectivity and Amphenol, to support large AI workloads. The move targets the wiring bottleneck that could cap AI infrastructure spending. Cisco, which has a market capitalisation of about $453.7b, faces competition from Arista and Juniper in AI networking, and analysts flag hardware mix and memory costs as a margin risk.

Cisco shares fall 3.3% to $114.52 as Webex AI agents keep working after calls end

Cisco Systems (NASDAQ:CSCO) has added AI agents to Webex that keep working on tasks after a conversation ends. Its shares traded at $114.52 on October 12, down about 3.3%. The agents use a tool called Dialog, which links customer history, company data, and backend systems so they can pursue unresolved requests. Claude integration is planned. Splunk tracks agent activity, and Cisco AI Defense provides safeguards. Shares sit 52.15% above the $75.27 GF Value estimate from GuruFocus. Cisco must turn the agents into higher recurring revenue without letting implementation costs and human supervision erode the gains.

NVIDIA and Cisco unveil USFP optics with 400Gb/s lanes and 4x bandwidth density

NVIDIA and Cisco announced Ultra-Dense Small Form Factor Pluggable (USFP), a new optical module for AI data centres, on October 12, 2026. They say it will be the first to support 400Gb/s-per-lane electrical signals, for capacity up to 12.8Tb/s. USFP offers 4x the bandwidth density and about 1.3x the power efficiency of 200Gb/s-per-lane modules. Operators can connect more computing systems without adding network tiers, while cutting networking's share of power use. The first transceivers will pack 16 full-duplex lanes in an octal small form factor-sized footprint, with 32 lanes or more planned. The companies are working with TE Connectivity and Amphenol on cages, connectors and modules. They plan an open industry specification through a community-led multi-source project.

Cisco and NVIDIA plan open 400G optics spec as Microsoft, Alibaba deploy P200 silicon

Cisco unveiled new chips, systems and optics for AI networks at the Open Compute Project Global Summit on October 12, 2026. With NVIDIA, it plans to create an open specification for Ultra-Dense Small Form Factor Pluggable (USFP), a 400Gb/s-per-lane optical module. Cisco says USFP should deliver 4x the bandwidth density and 1.3x the power efficiency of 200Gb/s-per-lane optics. Microsoft and Alibaba have put systems powered by Cisco's 51.2T Silicon One P200 into production. The first systems using the 102.4T G300 chip are shipping to customers. Cisco also introduced the 51.2T G302 chip for top-of-rack switches, which it plans to ship before the end of 2026. Its Live Protect security feature for SONiC customers starts in mid-2027.
