As of Q1'26 (2025-11-19), Cisco's latest revenue breakdown shows that the Networking segment leads with USD 7.77B, followed by Services at USD 3.81B and Security at USD 1.98B. Other notable segments include Collaboration at USD 1.06B and Observability at USD 274M, while smaller categories such as Other Products contribute minimally. Over the period from Q2'23 to Q1'26, the revenue composition has shifted, with Networking consistently dominating but showing some fluctuations, particularly a dip in early fiscal 2024 before recovering towards Q1'26. The Services segment demonstrates a stable upward trend, and Security revenue has grown notably, nearly doubling from Q1'24 to Q1'26. Collaboration and Observability segments have seen modest but steady increases, while legacy segments like Secure, Agile Networks and Internet for the Future are no longer reported in the latest quarters, indicating a strategic shift in Cisco's segment reporting and business focus.
