Company profile

researched Aug 2026

Knox Systems, Inc. is an AI-managed cloud provider that offers software vendors a pre-authorized federal cloud environment so their applications can be sold to and run by U.S. government agencies. Rather than each vendor pursuing its own Federal Risk and Authorization Management Program (FedRAMP) package, customers deploy into the Knox boundary and inherit Knox's existing Authorizations to Operate (ATOs). The company states this removes the need for customers to source their own agency sponsor and targets authorization in 90 days at roughly 90% lower first-year cost than the traditional path, which the company describes as costing $2-5 million up front with annual costs above $1 million.

The Knox Cloud is deployed on AWS, Azure, and Google Cloud and supports FedRAMP Moderate, FedRAMP High, and DoD IL4; IL5 is described as on the roadmap with a target of late 2026, while IL6 is not being actively pursued. Knox describes a bring-your-own-architecture model in which each customer receives a dedicated, single-tenant isolated sub-account. Its process runs from an initial architecture, data-flow and netflow review with scanning against NIST 800-53, through a commercial agreement, findings remediation, and go-live. The company positions itself as one of two major operators in this category, naming Palantir as the other.

Knox also markets a proprietary monitoring and remediation layer, KnoxAI, and publishes customer stories covering Adobe, Celonis, OutSystems, BigID, Armis, Resilinc, Spacelift, Sift, Sierra, Procurement Sciences, Sweetspot, Determinate Systems, Kovr.ai and Tovuti.
