Security Product Growth

CISCO SYSTEMS, INC. · 2025-09-03 · Importance 96 · Surprise 100

Security product revenue increased 59% (an incremental $3.0 billion) to $8.1 billion in fiscal 2025, driven largely by Threat Intelligence, Detection, and Response offerings that include Splunk. Growth also reflected expansion in SASE and Network Security offerings to a lesser extent. This category was the single largest contributor to product revenue growth and materially altered product category mix versus networking declines. The Security surge is directly tied to the Splunk acquisition and related observability/threat detection capabilities.
