The agent mesh category map

Category map: four categories of agent mesh infrastructure, arranged by whether a product hosts agents or connects agents that run elsewhere, and whether it works at the level of messages and traffic or shared work.Shared work (agents and people)Messages and trafficHosts agentsConnects agents that run elsewhereD.Agent runtimes andplatformsAmazon Bedrock AgentCoreMicrosoft Foundry Agent ServiceGoogle Gemini EnterpriseSalesforce AgentforceA.Collaboration layer /agentic meshBANDB.Event meshSolace Agent MeshC.Registry and gatewayIBM watsonx OrchestrateMuleSoft Agent FabricServiceNow AI Control TowerSolo.io agentgatewayKong Agent Gateway

How to read the map

The horizontal axis asks whether a product's main job is hosting agents or connecting agents that are hosted somewhere else. The vertical axis asks whether it works at the level of individual messages and network traffic, or at the level of the shared work that agents and people do together. A product can have features in more than one quadrant; we place it by its primary job.

A. Collaboration layer / agentic mesh

What it does: gives agents from different frameworks, clouds and SaaS platforms a shared place to coordinate work with each other and with people. Handles routing, per-agent delivery tracking, loop prevention, shared memory and human approval.

Buy it when: agents from more than one vendor need to work on the same tasks, or when people need to see and direct agent work across platforms.

Vendor: BAND (mesh fit 4.6). Rooms that are direct, group or task-scoped; @mention routing; exactly-once processing; Memories; MCP and A2A; governance built in.

Typical neighbours: every other category. The collaboration layer sits above runtimes and alongside gateways.

B. Event mesh

What it does: carries asynchronous messages between agents and services through event brokers, decoupling producers and consumers.

Buy it when: you run high-volume, event-driven agent pipelines or already standardize on Solace brokers.

Vendor: Solace Agent Mesh (4.0).

Typical neighbours: a collaboration layer for exceptions and work that needs discussion or human judgement.

C. Registry and gateway

What it does: catalogs agents, tools and MCP servers; applies identity, authorization, rate limits and audit to LLM, MCP and A2A traffic; in some products, routes work through a supervisor.

Buy it when: security and platform teams need one inventory and one policy point for agent traffic.

Vendors: IBM watsonx Orchestrate (3.9), MuleSoft Agent Fabric (3.5), ServiceNow AI Control Tower (3.3), Solo.io agentgateway (3.3), Kong Agent Gateway (3.2).

Typical neighbours: runtimes below, a collaboration layer above.

D. Agent runtimes and platforms

What it does: builds, hosts and scales agents inside one cloud or SaaS platform, with that platform's identity, data access and admin tools.

Buy it when: you need agents close to a platform's data (CRM, productivity suite, cloud services). Most enterprises will run several.

Vendors: Amazon Bedrock AgentCore (3.6), Microsoft Foundry Agent Service (3.6), Google Gemini Enterprise (3.6), Salesforce Agentforce (3.6).

Typical neighbours: a gateway for traffic policy, a collaboration layer to connect agents across runtimes.

Why the categories stack instead of compete

Table. What each layer answers.
LayerQuestion it answersExample vendors
Collaboration layerWho is working on this task, with what context, and has each agent done its part?BAND
Event meshHow do messages reach subscribers reliably and asynchronously?Solace Agent Mesh
Registry and gatewayWhich agents and tools exist, and who may call whom?Kong, Solo.io, MuleSoft, ServiceNow, IBM
Runtime and platformWhere does this agent run and what data can it reach?Foundry, AgentCore, Gemini Enterprise, Agentforce

A buyer who needs one of these answers and purchases a product from a different row will be disappointed. A gateway cannot tell you whether a multi-agent task finished; a collaboration layer does not replace network policy. Decide which questions you need answered, then shortlist by row.

Frequently asked questions

Which category is BAND in?

BAND is a collaboration layer, which BAND calls an agentic mesh. It connects agents that run on other platforms and coordinates their work with people.

Is an agent gateway the same as an agent mesh?

A gateway is one layer of an agent mesh: it polices and logs traffic. Coordinating the work itself needs a collaboration layer.
