Cisco designs and sells networking and communications technology and services. It creates networking equipment such as switches and routers used primarily by businesses and Internet service providers to route data such as emails, videos, files, and other digital communication. For example, an email that you send to a distant friend travels through various switches and routers made by companies like Cisco, Juniper, Huawei, and Alcatel-Lucent along the path to its destination.
Below are key drivers of Cisco's value that present opportunities for upside or downside to the current Trefis price estimate:
Over the past decade, Cisco Systems has remained the clear leader in core networking infrastructure markets, although its market share has moderated from the peak levels seen several years ago. In Ethernet switching, Cisco currently holds roughly 30% to 35% of the global market, down from levels that exceeded 50% historically. In routing, the company maintains an estimated mid-30% to around 40% share globally, still the largest position in the industry, but below the 50% plus levels it once commanded. Similarly, in enterprise wireless LAN, Cisco remains the market leader with approximately 25% to 30% share worldwide.
In addition to networking hardware, Cisco provides maintenance and support services to its customers to help them fix problems that occur with networking equipment. Cisco's network service revenues and profits are dependent on the installed base of Cisco switch and router equipment.
Management continues to emphasize subscription-based software, security analytics, and platform integration, which supports revenue stability and margin resilience over the long term.
