ServiceNow's Knowledge 2026 bet is to be the enterprise AI control plane — the layer that governs every agent. Why the positioning matters for 2026 buyers.
Key takeaways
At Knowledge 2026, Bill McDermott did not pitch ServiceNow as a model, a skill marketplace, or a workflow builder. He pitched it as the enterprise AI control plane — the layer where every agent in the enterprise is governed, observed, and routed, regardless of who built it or which cloud it runs on. The positioning is deliberate, defensible, and (importantly) consistent with where ServiceNow already wins in non-AI categories. This post unpacks the strategy, the moat, the risks, and what it means for buyers who are building agent portfolios that span multiple vendors.
The phrase control plane comes from networking and Kubernetes. It names the layer that decides what runs where, who is allowed to do what, what to do when things fail, and how to observe the whole system. The data plane does the work; the control plane governs it.
McDermott is borrowing the phrase on purpose. Enterprises already standardize on a single control plane for compute, networking, identity, and CMDB. The argument is that AI agents need the same treatment — and that ServiceNow, by virtue of already being where the workflow system of record lives, is the natural place for that control plane to land.
Four jobs, broadly:

ServiceNow's AI Control Tower is the concrete product. It governs ServiceNow-native agents and, via MCP and A2A, agents that live outside ServiceNow. That last point is the strategic move.
Action Fabric and AI Control Tower fit together like data plane and control plane. Action Fabric exposes workflow context — records, policies, approvals, audit. AI Control Tower decides which agent gets to read or write that context, under what conditions, with what audit. Without Action Fabric, the control plane has nothing to govern. Without the control plane, Action Fabric is a database with extra steps. They are designed as a pair.
Three reasons the control-plane framing is more than marketing:
Worth naming the risks, honestly:
Voice and chat agents have a tighter latency budget than most workflow agents. A customer on a phone call cannot wait for a heavyweight policy check on every utterance. The practical pattern that is emerging:

CallSphere ships complete AI voice agents per industry — 14 tools for healthcare, 10 agents for real estate, 4 specialists for salons. See how it actually handles a call before you book a demo.
That pattern is exactly how CallSphere is designed to live next to a control plane. The voice/chat agent handles 57+ languages, voice/chat/SMS/WhatsApp, and six verticals (healthcare, real estate, sales, salon, IT helpdesk, after-hours) at the latency the call requires, while writing back to ServiceNow records and respecting the control-plane policy. CallSphere is HIPAA-friendly, prices at $149/$499/$1,499 per month, and launches in 3–5 days — see pricing.
A pragmatic order for buyers building an agent portfolio in 2026:
Does the control plane lock me into ServiceNow models? No. The control plane is explicitly model- and cloud-neutral. Lock-in is on the workflow context and audit posture, which is the existing ServiceNow lock-in rather than a new one.
How does this compare to Google's Gemini Enterprise Agent Platform? Google is building a horizontal agent platform with partner agents pre-integrated. ServiceNow is building a control plane anchored on the workflow system of record. Different shapes; many enterprises will buy both.
Is the control plane required for production voice agents? Not for the call itself — voice agents must run at sub-300ms latency. The control plane governs the actions the voice agent commits (writing records, scheduling, charging), and audits the trace afterward.

Working memory, permanent memory, sandboxes, harnesses, governance — the practical blueprint enterprises are using to ship long-horizon AI agents in 2026.
A2A unlocks cross-vendor agent coordination, but most enterprise voice/chat workloads still ship faster on a single-vendor stack. Here is how to choose.
