AVGO vs CSCO: Which Enterprise Security Software Stock Has an Edge?

Broadcom (AVGO) and Cisco (CSCO) are positioned to benefit from the projected 14% growth in enterprise cybersecurity spending, driven by AI and cloud adoption, with both stocks up roughly 10% YTD. Broadcom's infrastructure software revenue, boosted by VMware Cloud Foundation, rose 25% YoY, and the company anticipates a 16% increase in Q3, fueled by AI-powered security, while Cisco's security revenue jumped 54% YoY, aided by Splunk and demand for Secure Access and XDR. While both companies are expanding their AI capabilities, Broadcom is currently leading due to strong demand for custom AI accelerators, though Cisco's valuation is more attractive based on forward Price/Sales.

Analysis

The enterprise cybersecurity market is poised for robust expansion, with Gartner forecasting a 14% increase in spending to $118.5 billion in 2025, and IDC projecting 12.2% growth in global cybersecurity spending for the same year, primarily driven by Generative AI adoption and cloud migration. Both Broadcom (AVGO) and Cisco Systems (CSCO) are well-positioned to capitalize on these trends, evidenced by their recent performance and strategic initiatives. Broadcom's infrastructure software revenue surged 25% year-over-year in its second quarter of fiscal 2025 to $6.6 billion, fueled by VMware Cloud Foundation adoption, and it anticipates a 16% YoY increase to $6.7 billion for the third quarter of fiscal 2025. A significant driver for Broadcom is its AI segment, with projected AI revenues of $5.1 billion in Q3 fiscal 2025, a 60% YoY jump, largely from its custom AI accelerators (XPUs). Cisco also demonstrated strong growth, with its security revenue climbing 54% YoY in Q3 fiscal 2025, boosted by the Splunk acquisition and robust demand for its Secure Access and XDR solutions, which added over 370 customers in the quarter. Both companies have seen positive revisions to their fiscal 2025 earnings estimates: AVGO's is projected at $6.63 per share (a 36.14% increase YoY) and CSCO's at $3.79 per share (a 1.61% increase YoY). While both firms have consistently beaten earnings estimates, Broadcom currently exhibits a stronger AI-centric growth narrative. Conversely, Cisco presents a more attractive valuation with a forward 12-month Price/Sales ratio of 4.38X versus Broadcom's 17.48X, although the article assigns both a "Value Score of D," indicating potential overvaluation. Year-to-date, AVGO shares are up 10.3% and CSCO shares are up 9.8%.

Key Decisions for Investors

• Investors should evaluate the compelling growth prospects in cybersecurity and AI, weighing Broadcom's significant AI revenue acceleration and infrastructure software strength against Cisco's robust security segment growth, enhanced by Splunk, and its considerably lower forward Price/Sales valuation.
• It is prudent to monitor the sustained execution of Broadcom's AI strategy, particularly the demand for its XPUs from hyperscalers, and Cisco's progress in integrating Splunk to further scale its security and observability platforms, as these are key performance indicators for each company.
• Despite positive operational momentum and stock appreciation, investors should exercise caution due to the "Value Score of D" assigned to both AVGO and CSCO, suggesting current valuations may be stretched, and note that both stocks carry a Zacks Rank #3 (Hold), implying a neutral near-term outlook from this specific rating agency.
