CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise teams drowning in manual compliance evidence collection will find genuine relief in Root Compliance Proofwork because it generates cryptographically signed artifacts on demand rather than forcing your engineers to hunt down screenshots and logs. The tool covers FedRAMP, CMMC 2.0, SOC 2, PCI DSS, and ISO 27001 with one-click exports, plus continuous monitoring against CISA's Known Exploited Vulnerabilities list, which actually moves the needle on audit cycle time. Skip this if your organization runs primarily on-premises infrastructure or needs the supply chain risk mapping that other vendors bake in; Proofwork optimizes for evidence generation over upstream SBOM analysis.
Mid-market and enterprise teams pursuing FedRAMP authorization without agency sponsorship should build Knox into their compliance path. The platform maps controls to NIST requirements automatically and generates ATOs across AWS, Azure, and GCP; its 15 existing authorizations mean you're following a pattern that regulators already accept. Skip Knox if your concern is continuous monitoring and threat detection; it prioritizes the compliance gate over runtime security posture.
