The AI-powered platform that generates assessment-grade System Security Plans in days, not months. Purpose-built for DoD and federal systems undergoing RMF Assessment & Authorization.
Every control narrative requires understanding the specific system, its boundaries, data flows, and technical implementation. Multiply that by 421 controls, and you're looking at hundreds of hours of expert time.
From system intake to complete SSP package in four steps.
Tell us about your system: type (cloud, on-prem, air-gapped, cross-domain, tactical), environment, data classification, and architecture.
Our engine generates control-specific questions based on your system type. Answer them in plain language — no NIST expertise required.
AI produces SCA-verifiable control narratives tailored to your specific infrastructure, using your responses and system context.
Download your complete SSP package as DOCX, PDF, or OSCAL JSON. Includes gap analysis and auto-generated POA&M items.
Not another checklist tool. ATOExpress understands the nuance of different system types, environments, and assessment requirements.
NIST 800-53 Rev 5 (Low/Moderate/High), FedRAMP, CMMC 2.0, and NIST 800-171 — all from a single platform.
Questions adapt based on system type: cloud, on-prem, air-gapped, cross-domain, or tactical. No irrelevant questions.
Generated narratives are structured for Security Control Assessor review — specific, measurable, and traceable to implementation.
Export complete SSP packages as DOCX (for editing), PDF (for submission), and OSCAL JSON (for machine validation).
Identifies unmet controls and auto-generates POA&M items with risk ratings and suggested remediation actions.
Rate limiting, CSRF protection, CSP headers, RBAC, encrypted data at rest. Available as SaaS or self-hosted for classified environments.
The adaptive intake engine tailors questions and narratives based on your specific deployment model.
