Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Security teams training ICS defenders on a budget should use GRFICS because it's free and lets operators practice real attack chains in a visual 3D environment instead of reading documentation or staring at command lines. The framework runs on Unity and requires no licensing, making it practical for manufacturing facilities and utilities that can't justify expensive simulators for tabletop exercises. Skip this if your team needs NIST Govern function support or compliance reporting; GRFICS is pure hands-on practice, not an audit tool.
Security teams building a cybersecurity workforce from scratch should choose SudoCyber for its hands-on lab environment that actually forces people to break things and fix them, not just click through modules. The platform covers CompTIA Security+, Network+, and CEH certifications while offering Capture the Flag competitions that make training stick better than passive content; it directly strengthens NIST CSF 2.0's Awareness and Training function. Skip this if your org needs enterprise-scale role-based learning paths or integration with your existing LMS; SudoCyber's strength is depth in technical skills for smaller teams, not breadth across hundreds of users with different compliance requirements.
GRFICS is a Unity 3D-based framework that provides a virtual industrial control system environment for practicing ICS security attacks and defenses with visual feedback.
