DEFONEOS PER-TIER PRICING DETAIL

1. PRICING PHILOSOPHY

DEFONEOS pricing is per-tier run-rate: T1 for solo operators, T2 for departmental pilots, T3 for UK MOD live deployments. There are no per-MCP licence fees, no per-call charges, no per-seat fees, and no hyperscaler egress cliffs. The DEFONEOS composable substrate is OSS-licensed (Apache-2.0 / MIT / OGL-3.0 / CC-BY-4.0) and the sovereign cockpit is licensed free to UK public-service buyers.

Every pound traces to a cost line. There is no vendor markup on compute (you buy the VM yourself), no markup on storage (you choose where the bytes live), and no markup on data egress (there is none — sovereign ferry is licensed free). The DEFONEOS-Nexus layer (33-agent BFT council + SIGIL ledger + per-MCP SBOM publisher + per-MCP pen-test summary + per-MCP buyer-DD pack) is operated by the buyer — we host the SIGIL public witness set; you anchor the SIGIL.

This open-model arithmetic is auditable. Every line below ties to a specific tool, deployment step, and unit cost. The buyer's TCO calculator (runnable in <60s on a fresh VM) is at the bottom of this page.

2. TIER MATRIX

Comparative US-cloud baselines (Cyera Open Compliance · AWS GovCloud · Azure Gov Cloud · Crowdstrike Falcon · Wiz) per UK Crown Commercial Service benchmarks 2026-Q2 for comparable feature set including: SBOM publishing, BFT audit log, SIGIL signature chain, pen-test summary, evidence-freshness probes, JML lifecycle.

3. 11 COST LINES — T1 SOLO

4. 11 COST LINES — T2 DEPARTMENT

5. 11 COST LINES — T3 MOD

6. 5 COST-RISK BANDS

Risk bands priced against 90-day tail-risk scenarios per UK NCSC CISA-tabulated threat curves. R5 Critical assumes a single-sovereign-ferry compromise triggering substrate rotation — full price recovery follows DEFONEOS-REDLINE-MOTION-27/33 process; see /defoneos-redline-motions-history.html.

8. OPEN-MODEL ARITHMETIC — VERIFICATION

The price points above are open-model arithmetic: every line ties to a real tool, a real deployment step, and a real unit cost. The buyer's TCO can be re-derived on a fresh calculator. No black-box contracts, no per-call charges, no hidden egress cliffs. The DEFONEOS-Nexus layer is OSS-licensed. The sovereign compute substrate (Hetzner / OVHcloud / VPS.NET UK) is buyable from any UK address.

For the canonical cost-benefit model and US-cloud stack comparison see /defoneos-pilot-cost-benefit-model.html (16449b).

# Run on a fresh VM (Linux 4.x, Python 3.11+)
python3 - <<'PY'

Calculator is illustrative only — actual buyer TCO depends on procurement vehicle and confirmable buyer-specific scope. The full stack is bookable via the G-Cloud 14 catalogue entry (in queue).
