Orbix AI-SPM: Implementing Enterprise-Grade Runtime Security for AI Systems

Orbix AI-SPM — Runtime Security for AI Systems

Orbix AI-SPM is an open-source implementation of enterprise-grade runtime security designed for distributed AI systems. It shifts the paradigm from trusting model outputs to controlling system-wide execution through an event-driven architecture.

Why This Matters

Modern AI deployments are no longer isolated models but complex systems involving agents, RAG pipelines, and external tools. Relying solely on prompt engineering and static guardrails creates massive attack surfaces, including prompt injection and privilege escalation, which require a dedicated runtime enforcement layer to mitigate real-world risks effectively.

Key Insights

• Orbix security validation using the Garak red-teaming toolkit (2026) showed successful prevention of policy bypass and data exfiltration.
• Policy Enforcement via Open Policy Agent (OPA) allows for dynamic allow, block, or escalate decisions based on user identity and prompt semantics.
• Kafka is utilized as an event backbone within the architecture to provide full auditability and replayability of agent-tool interactions.
• The Guarded Ingress Layer implements early rejection of unsafe inputs through JWT authentication and regex-based prompt inspection.
• Memory governance ensures session-scoped access and integrity checks to prevent data exfiltration via ‘print everything’ injection attacks.

Practical Applications

• Use case: RAG-based systems using Orbix to sanitize context and validate trust to prevent indirect prompt injection from poisoned external data. Pitfall: Implicitly trusting retrieved data allows attackers to execute system-level commands via document poisoning.
• Use case: Agent-based tool orchestration where Orbix enforces schema validation and policy-gated execution for API calls. Pitfall: Unscoped tool access can lead to unauthorized data exposure or API abuse through instruction hijacking.
