[ AGENT_SPRAWL_RISK_CALCULATOR / 2026 ]

What is your agentic sprawl exposure?

Enter four numbers about your AI agent footprint. The calculator estimates annualized sprawl exposure across breach risk, compliance penalty risk, x402 stablecoin leakage, drift overrun, and the multi-vendor seam tax, then compares to running it through Centurian.

[ INPUTS ]

EU AI Act penalty exposure (1% × 7% × $175,000,000 revenue)$122,500
x402 stablecoin leakage (no autonomous payments)$0
Drift / regression overrun (50 × $2,400 × 4%)$4,800
Multi-vendor seam tax ($270K base + $1,200 × 50 agents + $45K × 3 platforms beyond the first)$465,000
[ THROUGH_CENTURIAN ]

How the math works

[ SHADOW-AGENT_BREACH_EXPOSURE ]

52% of corporate AI agents are actively monitored (Gravitee 2026). The other 48% are shadow agents. Average shadow-AI breach: $5.39M (IBM Cost of a Data Breach Report 2026). Probability of a given shadow agent breaching in one year: ~0.35% based on observed incident frequency.

[ EU_AI_ACT_PENALTY_EXPOSURE ]

EU AI Act Annex III high-risk obligations take effect December 2, 2027 (moved from August 2, 2026 by the 2026-05-07 Digital Omnibus deferral). Penalties reach 7% of global annual revenue or €35M, whichever is higher, once the obligations bind. We use a 1% annualized probability for a documented violation in a high-risk context. Revenue assumed at $350K per employee (mid-market median).

[ X402_STABLECOIN_LEAKAGE ]

Agents that pay autonomously through Coinbase CDP, Cloudflare, or Stripe x402 facilitators leak ~$1,400/yr/agent in unattributed spend (drift, retried failed transactions, agents using their own funded wallets without registry mapping). Card- rail FinOps tools cannot ingest these firehoses with per-agent attribution.

[ DRIFT_/_REGRESSION_OVERRUN ]

Trajectory drift inflates per-agent run cost ~4% before detection. Average per-agent run cost: $2,400/yr (model + tool + observability). Without continuous trajectory eval, drift compounds quietly.

[ MULTI-VENDOR_SEAM_TAX ]

Stitching multi-vendor agent governance + cost attribution + compliance reporting without a unified spine: $270K base (Salesforce Agent Fabric or Credo AI license + custom x402 reconciliation script + Big-4 audit consultant) + ~$1,200 per agent for ongoing integration upkeep. Sourced from observed mid-market deployments and the v4.1.2 marketing plan TCO comparison.

[ CENTURIAN_RESIDUAL ]

Centurian Professional tier reference: $30K/yr. Residual breach + compliance exposure ~5% of the DIY equivalent (after registration, governance, and continuous audit are in place). Multi-rail Cost product zeros x402 leakage. Trajectory eval zeros drift overrun. Cross-vendor unified audit eliminates seam tax.

This calculator is a directional estimate, not an audit. Numbers shift with industry, agent shape, framework mix, and operator mode. For an audit-grade exposure assessment, request a Compliance-Anchor engagement once you have early access.
