Agent Ecosystems

How do we secure Agent-to-Agent (A2A) communication?

Agent-to-Agent (A2A) communication is secured by requiring explicit authentication and authorization for every agent interaction. Each agent must present a verifiable identity, and every request must be evaluated against policy before execution. Agents must never implicitly trust other agents, even within the same system or tenant.

What is the “Agent Communication Protocol” (ACP)?

The Agent Communication Protocol (ACP) is a structured way for agents to exchange messages, tasks, and intent. It defines standardized formats for requests and responses so interactions can be validated, governed, and audited. ACP replaces informal or ad-hoc agent communication with explicit, policy-enforceable exchanges.

How do we integrate Agentic IAM with API Gateways?

Agentic IAM integrates with API gateways by enforcing identity and access controls at the gateway layer. The gateway validates agent tokens, checks scopes and permissions, applies rate limits, and blocks unauthorized requests before they reach backend services. This ensures agents cannot bypass identity policies when accessing shared APIs.

How do we enforce allowlists for outbound HTTP tools?

Outbound HTTP allowlists restrict agents to a predefined set of approved destinations and APIs. Any attempt to call an endpoint outside the allowlist is denied by default. Allowlisting prevents agents from sending data to unknown services, reduces exfiltration risk, and limits the expansion of agent capabilities.

What are Multi-Agent Systems (MAS)?

Multi-Agent Systems (MAS) are environments where multiple autonomous or semi-autonomous agents operate simultaneously and interact with each other. Agents may collaborate, delegate tasks, or specialize in different functions while working toward shared objectives. MAS increase scalability but also introduce coordination and security complexity.

How does SCIM provisioning apply to agent ecosystems?

SCIM provisioning is used to create, update, and decommission agent identities across systems in a standardized way. In agent ecosystems, SCIM manages non-human identities, ensuring agents are onboarded with correct roles and removed automatically when no longer needed.

What are digital supply chains in agent ecosystems?

Digital supply chains describe how data, decisions, and actions flow across multiple agents and systems. One agent’s output often becomes another agent’s input. Without strong identity and policy controls, errors or misuse can propagate across the chain, increasing systemic risk.
