NET strengths
- →Unique global network with PoPs in 300+ cities creates a low-latency performance advantage over software-only security vendors
- →Workers AI and developer platform represent a new AI inference revenue stream beyond security
- →Broad platform approach across security, performance, and developer tools creates deep enterprise expansion potential
ZS strengths
- →Purpose-built zero-trust architecture is purpose-designed for cloud and remote work security — not retrofitted
- →High net revenue retention as customers expand from ZIA to ZPA to data protection and AI security modules
- →Government and highly regulated enterprise penetration provides sticky, long-cycle revenue
Risks to watch — NET
- →Not yet GAAP profitable and requires continued strong execution to justify a high revenue multiple
- →Competes with well-resourced incumbents across every product category (Zscaler, Palo Alto, Akamai)
- →Developer platform monetisation is early and may take longer than expected to contribute materially
Risks to watch — ZS
- →Valuation remains elevated relative to near-term revenue growth
- →Palo Alto Networks and other platform consolidators are aggressively bundling competitive zero-trust products
- →Sales cycle length makes revenue lumpy and sensitive to macro IT spending slowdowns
