# Guardian Posse Cybersecurity > Guardian Posse Cybersecurity is a mathematics-verified AI cybersecurity and compliance platform with a nuclear and OT vertical. It deploys 12 specialized AI defense agents grounded in the Sovereign 144 Master Equation and 49 deterministic proofs for NIST 800-53, NIST 800-171/172, CMMC Level 2/3, RMF, NRC 10 CFR 73.54, IAEA NSS 17, and IEC 62443 compliance automation. ## About Guardian Posse Cybersecurity was founded by James Collins and Greg Hyatt. Headquartered in Russellville, Arkansas, the platform serves clients worldwide — including nuclear facilities, ICS/OT operators, and DoD subcontractors. The core innovation is the **Sovereign 144 Mathematics Engine V3.2.4**: Master Equation Ω = N · (Φ_W · r · Ψ_B · δ_A) = 1.0. If Ω ≠ 1.0, the input is rejected. Every defense decision is deterministic mathematics, not heuristics.

Hardware data sovereignty. - **CL-I — PCM^rtos MLC Cell-State Physics**: RTOS-governed multi-level cell state. Physical memory boundaries are the security primitive — not software permissions. - **CL-II — AI Governor Four-Gate (TSOV / ISRI / MSOV / TPRF)**: Four sequential gates. Every transaction must pass all four. No gate is advisory. - **CL-III — Asymmetric Dual-Codebook Sovereignty**: Encoder and decoder each hold asymmetric codebook halves. Single-side compromise yields nothing decodable. - **CL-IV — GP Cybersecurity Intelligence Layer (Capstone)**: NIST/CMMC/NRC/IAEA/IEC 62443 compliance automation, 12 defense agents, SHA-256 receipts.
