Pros

  • SOC 2 Type 2 certified; ISO 27001 datacenters; BAAs available¹
  • Containers run as isolated VMs — tenants never share kernels¹

  • Third-party pentests by Atredis Partners, Doyensec, and Tetrel¹
  • Zero-config private networking: no Terraform, VPC setup, or IAM¹

Cons

  • No independent user reviews found; all evidence is vendor marketing¹
  • Requires engineering skill; not a no-code or hands-off host¹
  • Key managed services are third-party brands: Supabase Postgres, Upstash¹

Gotchas

  • mediumOnly evidence located is vendor marketing; zero independent reviews found¹

  • lowSOC 2 reports, BAAs, and pentest intros require a sales conversation¹

Not for
