Answer box
The AI control plane is the category that emerged in 2026 to govern enterprise AI usage end-to-end — discovering AI assets, controlling access, inspecting prompts and responses inline, governing autonomous agents, and producing compliance evidence. It is distinct from CASB (SaaS-traffic-focused), DLP (file and email-focused), and SIEM (log aggregation). The AI control plane complements all three but covers the AI-specific layer none of them was built for. This hub covers definitions, what each capability category does and doesn't cover, the vendor archetypes, and the complete AccuroAI library.
The capability matrix: CASB + DLP + SIEM vs AI Control Plane
The same matrix AccuroAI publishes on the homepage, with context:
| Capability | CASB + DLP + SIEM | AI Control Plane |
|---|---|---|
| Shadow AI discovery | Partial (browser-only at best) | Complete (browser, SaaS, network, endpoint, MCP, agent) |
| Prompt-level DLP | No | Real-time, <38ms p99 |
| Response inspection | No | Redact, warn, block, log |
| Autonomous agent governance | No | Yes — same policy engine |
| OWASP Agentic Top 10 coverage | No | First-class |
| Tool poisoning defense | No | Tool description + response inspection |
| A2A trust / inter-agent | No | Signed envelopes, inspected messages |
| Kill switch (per-agent) | No | Sub-second mean time to kill |
| Compliance evidence (NIST/ISO/EU AI Act) | Manual spreadsheet | Auto-mapped, exportable |
| Deployment time | 3-6 months | <30 minutes |
The structural answer: CASB + DLP + SIEM remain valuable for their original surfaces. The AI control plane adds the AI-specific layer.
What an AI control plane covers
Eight capability areas from our Workforce AI Security Buyer's Guide and AI-SPM Buyer's Guide 2026:
- Shadow AI discovery across browser, SaaS, network, endpoint, MCP, agent surfaces.
- Access control + SSO with major IdPs and major AI platforms.
- Inline prompt inspection at sub-50ms p99.
- Inline response inspection at the same latency.
- Cross-platform unified coverage — same policy engine across ChatGPT Enterprise, Claude Enterprise, Microsoft Copilot, Gemini Workspace, Perplexity, custom GPTs, MCP-based agents.
- Unified audit trail — one searchable record per task across platforms.
- Policy as code — versioned, scoped per user / group / app / data class.
- Compliance evidence + incident response — kill switches with sub-second mean time to kill.
Vendor archetypes (from the AI-SPM Platforms Compared piece)

FAQ
Does the AI control plane replace my CASB or DLP? No. CASB and DLP cover their original surfaces (SaaS, files, email) and remain valuable. The AI control plane complements them by covering the AI-specific layer — prompts, responses, agent actions, MCP — that legacy tools were not built for.
Is "AI control plane" the same as AI-SPM? Overlapping. AI-SPM (AI Security Posture Management) is the analyst-named category. "AI control plane" is the architecture term that emphasizes the active-control function alongside posture. Most vendors in 2026 ship both.
How does an AI control plane relate to Guardian Agents? Guardian Agents (Gartner-named) are an active-governance subcategory within the broader AI control plane category. They emphasize the agentic dimension specifically.
Can Microsoft Purview AI Hub serve as our AI control plane? For Microsoft-only environments where Copilot is the dominant AI footprint, Purview AI Hub covers a meaningful share of the capability matrix. For multi-AI environments, most enterprises layer a dedicated AI control plane above Purview.
What's the typical deployment timeline? <30 minutes for the AI control plane initial stand-up (AccuroAI benchmark). 30-90 days for full integration across IdP, SIEM, ticketing, GRC. 6-12 months for organizational change management to mature.
