At Horizon3.ai, we believe that security must be proven, not presumed. That’s why our NodeZero Federal™ platform is now FedRAMP High Authorized—a milestone that reflects our operational maturity, technical rigor, and unwavering commitment to protecting the nation’s most sensitive government systems.
This blog outlines what FedRAMP High means, how we achieved it, and why it matters to our government and enterprise partners navigating complex compliance requirements and mission-critical environments.
What is FedRAMP
The Federal Risk and Authorization Management Program (FedRAMP) is a U.S. government-wide framework designed to standardize the security assessment, authorization, and continuous monitoring of cloud services. Any cloud-based provider seeking to serve federal agencies must meet FedRAMP’s security requirements—and the level of authorization depends on the sensitivity and impact of the data involved.
FedRAMP defines three tiers of risk impact:
- Low: Public data with minimal risk if exposed.
- Moderate: Sensitive but unclassified data, such as internal communications or procurement records.
- High: Data where compromise could cause catastrophic harm to operations, assets, or individuals—such as law enforcement records, national security data, health systems, and financial infrastructure.
FedRAMP High is the most stringent level. It requires compliance with 421 NIST SP 800-53 Rev. 5 controls and is mandatory for systems supporting high-impact federal workloads.
What FedRAMP High Authorization Means
Becoming FedRAMP High Authorized isn’t just a stamp—it’s a signal of trust, security excellence, and readiness for mission-critical deployment.
Here’s what it means for our NodeZero Federal platform:
Authorized to operate in civilian environments handling high-impact data.
Approved after a comprehensive security review by a FedRAMP-accredited Third Party Assessment Organization (3PAO).
Cleared as a secure SaaS solution under the FedRAMP High baseline, with enforced single sign-on (SSO) and multi-factor authentication.
Aligned with the latest government cybersecurity mandates, including OMB M-22-09 (Zero Trust), and NIST SP 800-53 Rev. 5.
For agencies and integrators, this authorization accelerates procurement, shortens their ATO timelines, and eliminates the need for redundant security evaluations.
Our Journey to FedRAMP High
Achieving this authorization was a company-wide initiative that required operational discipline, technical transparency, and a relentless focus on security outcomes.
We successfully completed a rigorous audit of our infrastructure, controls, and documentation. Through this process, we demonstrated alignment with federal audit standards, including real-time visibility, continuous monitoring, and effective control implementation.
Our goal wasn’t just to pass an audit—it was to operationalize trust for the agencies and missions that depend on us. The result is a production-safe platform already validated through real-world deployments. For example, the NSA’s Continuous Autonomous Penetration Testing (CAPT) program is powered by the commercial version of our NodeZero® platform.
Security Measures That Set Us Apart
NodeZero Federal is more than compliant; it’s built for high-consequence environments where assumptions are dangerous and delays are costly.
What sets us apart:
- Autonomous, production-safe pentesting that emulates real attack paths without agents or integrations.
- Credential-optional testing that exposes misconfigurations, policy violations, and trust boundary weaknesses.
- One-click retesting to instantly verify remediation with no consultants or wait time
- Alignment with real-world adversary behavior, not theoretical vulnerabilities.
Where most tools simulate risk, NodeZero Federal proves it safely, continuously, and with clarity.
Benefits to Our Government & Enterprise Clients
Whether you’re operating in a federal agency, a defense contractor, or a regulated commercial environment, FedRAMP High matters because it signals that your vendor can meet the highest bar.
With NodeZero Federal, you get:
- Verified trust from the FedRAMP PMO and 3PAO-reviewed architecture.
- Faster time-to-value for compliance-sensitive deployments.
- Reduced friction in audits, risk assessments, and mission-readiness exercises.
- Demonstrable improvement in security posture, validated through live attack chaining and exploitation metrics, plus proof that previous weaknesses have been remediated.
Already, NodeZero is powering thousands of assessments across DIB networks. Now, similar capabilities are cleared for your agency or organization.
Why It Matters to You
If you’re a federal agency, you now have access to a FedRAMP High Authorized autonomous pentesting platform that delivers proof-based security without disruption.
If you’re an integrator, you gain a partner who simplifies your compliance journey.
If you’re a decision-maker, you can finally align cybersecurity with measurable outcomes—not assumptions.
