Frequently Asked Questions
What are the best cybersecurity startups in 2026?
Based on GitHub engineering acceleration data, the top cybersecurity startups in 2026 are gravitational, fleetdm. Rankings are based on commit velocity change — the rate at which engineering output is accelerating.
How are these rankings determined?
Startups are ranked by commit velocity change — the percentage change in 14-day commit counts versus the prior period. This measures engineering acceleration, not absolute size. Read the full methodology.
