 Redpanda ADP addresses critical enterprise requirements across all components.
 
-* *Security by design* MCP servers enforce policies at the tool level, programmatically preventing prompt injection, SQL injection, and other agent-based attacks. Policy enforcement is deterministic and controlled. Agents cannot bypass security constraints even through creative prompting.

-* *Unified authorization*:: All components use OIDC-based authentication with an on-behalf-of authorization model. When a user invokes an agent, the agent inherits the intersection of its own permissions and the user's permissions. This ensures proper data access scoping.

-* *Complete observability*:: Redpanda ADP provides two levels of inspection. Execution logs (transcripts) capture every agent action with 100% sampling using OpenTelemetry standards. Real-time debugging tools allow you to inspect individual MCP server calls down to individual tool invocations with full timing data. You can view detailed agent actions in glossterm:Redpanda Console[] and replay data for agent evaluations.

-* *Compliance and audit*:: For industries requiring multi-year audit trails, Redpanda ADP records every agent action and data source used in decision-making. Execution logs are stored in Redpanda topics and can be materialized to Iceberg tables for long-term retention and analysis.
