AI Summary

6.0
Neutral

FTNT's AI-enabled security-and-networking platform is driving a credible demand inflection, but at ~53x earnings and 15x sales, investors should only add exposure if billings, service revenue, and margins remain resilient as the exceptional 52% product-growth cycle normalizes.
