Knox Systems Achieves FedRAMP High Authorization

Knox has achieved 16th federal sponsor, FEMA for Fed High authorization.

The Federal Risk and Authorization Management Program (FedRAMP) Marketplace lists 518 certified cloud services, yet only 48 hold FedRAMP High authorization. For Software-as-a-Service (SaaS) companies targeting Department of Defense (DoD) contracts or agencies handling high-impact data, authorized platforms remain scarce. Federal cloud spending reached $17 billion in 2024, with high-impact systems accounting for roughly 40% of expenditures.

UberEther's IAM Advantage platform holds FedRAMP High authorization, but its boundary is purpose-built around identity, credential, and access management (ICAM) workloads, runs only on Amazon Web Services (AWS) GovCloud, and carries a single reuse. For SaaS companies outside ICAM, or that need multi-cloud flexibility, these constraints narrow its fit.

This article profiles five alternatives, each assessed on authorization level, cloud infrastructure, control inheritance, and deployment model.

Key Takeaways

• FedRAMP High supply is limited. Only 48 fully authorized FedRAMP High offerings are available in the FedRAMP Marketplace.
• Boundary scope determines fit. An ICAM-specific boundary serves identity workloads; general-purpose SaaS applications require a general-purpose FedRAMP boundary.
• Control inheritance affects timelines. Inherited authorization models can compress the amount of infrastructure compliance work a SaaS vendor must own directly.
• Authorization path shapes execution. FedRAMP High, DoD alignment, cloud choice, and deployment model all affect which platform is practical for a given product.

Where UberEther Fits and Where It Falls Short

UberEther is a domestically owned small business founded in 2010, focused on ICAM for federal and defense agencies. Its flagship product, IAM Advantage, is a pre-integrated Zero Trust identity platform.

• FedRAMP High authorized. IAM Advantage achieved FedRAMP High authorization in October 2023.
• Pre-integrated Zero Trust identity platform. Comes pre-loaded with 100+ use cases and integrates with leading ICAM technology stacks.
• Express Advantage shared-authority model. Positioned as a mutual authorization boundary option for software companies.
• AWS GovCloud deployment. Single-cloud architecture with one Marketplace reuse.
• ICAM-specific authorization boundary. Designed around identity workloads rather than general-purpose SaaS.
