Knox Systems

Managed federal cloud for FedRAMP authorization

Overview

Knox Systems runs a managed federal cloud that helps SaaS and AI developers obtain FedRAMP authorization and sell to U.S. government agencies by hosting apps inside a pre-authorized boundary. Each application operates in an isolated, single-tenant environment on AWS, Azure, or Google Cloud, and the platform supports FedRAMP Moderate and High, GovRAMP, and DoD IL4 (IL5 in progress). Knox AI automates evidence collection, vulnerability monitoring, and reporting, while security and risk operations centers perform continuous monitoring, and the service provides hardened container images and connections to agency sponsors. The goal is to simplify government cloud compliance and speed the path to federal markets for commercial software providers.

Simplify's take

What believers are saying

  • Harvey won FedRAMP Class D through Knox on October 28, 2026, validating premium demand.
  • Arch Systems, Wraithwatch, and AidFinder all landed Knox-based authorizations in November 2026.
  • Belisar integration on October 13, 2026 helps customers convert compliance wins into government revenue.

What critics are saying

  • FedRAMP becomes commoditized if agencies accept native cloud controls from AWS, Azure, Google.
  • Knox's model depends on a few hundred vendors; one failed authorization damages trust fast.
  • A major breach inside Knox's boundary would cripple every customer and likely end the company.

What makes Knox Systems unique

  • Knox raised $25M on March 17, 2026 to sell 90-day FedRAMP paths.
  • Its managed federal cloud spans FedRAMP High, DoD IL4, and September 2026 IL5.
  • Knox bundles authorization, continuous monitoring, and agency sponsorship into one onboarding motion.

Arch Systems brings factory AI to defence manufacturers via Knox FedRAMP Class D partnership

Arch Systems, a maker of manufacturing data and analytics software, can now deploy its Data Foundation and AI applications in Federal Risk and Authorization Management Program (FedRAMP) Class D environments. It did so through a partnership with Knox Systems, a federal managed cloud provider, announced on November 9, 2026. Defense manufacturers can run a single-tenant Arch instance in the Knox environment, which they own and control. Those who prefer can use their existing private cloud instead. Arch has served defense customers only at the edge until now. The full hybrid architecture, including its Connector Platform, is now open to them, and it can handle Controlled Unclassified Information. "They no longer have to choose between security and progress," said Andrew Scheuermann, chief executive officer of Arch Systems. The offering is available now to qualified federal, defense, and regulated manufacturers.

Wraithwatch gains FedRAMP Class D certification via Knox for AI-native cyber defence

Wraithwatch, an AI cyber defence company founded by veterans of SpaceX, Anduril, Palantir, and Joint Special Operations Command, has achieved Federal Risk and Authorization Management Program (FedRAMP) Class D (High) Certification. It earned the certification on November 3, 2026, in partnership with Knox Systems, which runs the largest managed federal cloud. Federal agencies can now deploy Wraithwatch's platform, which uses swarms of AI workers to build a continuously updated digital twin of their networks. Analysts can query it in natural language to hunt threats, assess compliance, and predict attacker moves. The company says three-day threat hunts now take under 15 minutes, and six-week authority to operate (ATO) assessments take under 30 minutes. "Cyber defence is moving away from human-led actions at human speed to machine-led actions at machine speed," said chief executive officer Nik Seetharaman.

Harvey achieves FedRAMP Class D Certification through partnership with Knox Systems.

Harvey achieves FedRAMP Class D Certification through partnership with Knox Systems. Certification brings leading legal AI to federal agencies and partners, giving government legal teams more capacity to serve the public SAN FRANCISCO and WASHINGTON, Oct. 28, 2026 /PRNewswire/ - Harvey, the operating system for legal and professional services, today announced it has achieved Federal Risk and Authorization Management Program (FedRAMP) Class D Certification in partnership with Knox Systems (Knox), the largest, longest-running federal managed cloud. Trusted to serve 80% of the AmLaw 100 law firms and five of the Fortune 10, this FedRAMP Certification extends Harvey's reach to U.S. federal agencies, federal contractors and partners, international governments, and commercial organizations with the highest security requirements. Federal legal teams carry an enormous share of the government's workload. Agency counsel review solicitations and contractor agreements, process Freedom of Information Act (FOIA) and public records requests, run investigations and litigation, and advise leadership on regulatory and policy questions, and much of the work is done manually. Harvey's platform alleviates the groundwork burden and enables federal attorneys to spend more time on the analysis, advice, and decisions that require their judgment. With this FedRAMP Class D Certification, federal legal teams and their contracting agencies can now use Harvey for: * Procurement and contracting: Review solicitations, contractor agreements, and contract modifications against agency requirements and playbooks. Flag deviations and prepare suggested edits in Harvey or Word. * First-pass document review: Review correspondence, reports, and supporting records to identify material potentially responsive to FOIA and other public records requests. Citations help attorneys verify findings before making disclosure decisions. * Investigations and litigation: Build chronologies from correspondence, witness statements, and case files. Identify gaps and conflicting accounts, and surface evidence relevant to allegations, claims, and defenses. * Regulatory and advisory work: Research statutes, regulations, and prior legal opinions to assess policy proposals, interpret statutory duties, and prepare advice for agency leadership and program offices. * Cross-agency collaboration: Bring together counsel from different agencies and components for joint investigations, policy reviews, and shared legal questions. Work from common documents and conversation history, with controlled access. "Trust has to be earned and verified, which is why Harvey treats security as something we prove, not something we claim," said Brooks Evans, Chief Information Security Officer of Harvey. "FedRAMP Class D Certification isn't a one-time assessment. It's one of the most demanding security standards there is, and we meet it every day through continuous monitoring and accountability. That's what allows agencies and their partners to bring their most consequential legal work to Harvey with confidence."

AidFinder wins FedRAMP Class C certification in 37 days with Knox Systems

AidFinder, an AI-powered disaster recovery platform for emergency management agencies, has achieved Federal Risk and Authorization Management Program (FedRAMP) Class C Certification in 37 days. It is the fastest timeline its partner, Knox Systems, has led to date. The certification clears the way for government agencies to deploy the platform for their residents. Survivors tell their story once, and an AI agent prepares applications on each aid program's own website. Survivors approve every submission before it is sent. Knox cuts a process that often takes years to a 90-day commitment by hosting customers inside its already-certified boundary, where they inherit most required controls. Chief executive Jonathon Nostrant founded AidFinder after the Palisades Fire damaged his home. Former FEMA Administrator Craig Fugate advises the company.
