Multi-region. Included in the price.

Unlike traditional cloud storage, Cubbit automatically encrypts, fragments, and replicates data across multiple locations — safe from ransomware and disasters.

Traditional cloud storage

  • 1 bucket = 1 location (single-region)
  • DC/connection failure? You lose data access
  • 2–3× cost for multi-region

Cubbit

  • 1 bucket = spread across multiple locations
  • DC/connection failure? Data stays accessible
  • Geo-distribution by design
