Top Cybersecurity Companies (October 2026)
Cybersecurity ranked by growth.
Two of the top cybersecurity companies on our list share the lead at an MGI of 70, and they could hardly be more different underneath. CrowdStrike, at $113B, keeps 29% per-share growth from a 32% headline rate. Rubrik's revenue per share fell 35% a year even as revenue rose 34%, growth financed by an expanding share count.
That contrast is the lesson of the whole 13-name group. The median MGI of 50 splits platform leaders like Fortinet at 69 and Cloudflare at 67 from the specialists below, and dilution is the quiet variable running through security software. The per-share column is where it shows first. Click any company for the full citation-backed analysis.
