Trussed vs. Noma Security
AI Posture Management vs. Inline MCP Governance. Noma Security is a comprehensive AI security platform centered on AI Security Posture Management (AI-SPM), continuous asset discovery, agentic risk mapping, AI red teaming, and runtime protection. Trussed is a production AI control plane focused on inline governance of individual AI interactions, prompt security, data protection, code artifact inspection, and audit evidence generation.
Visibility alone does not govern interactions
Production AI security has two distinct requirements that are often confused: knowing what AI is running and controlling what it does when it runs. Posture management and asset discovery are essential, but posture visibility does not enforce controls on individual interactions. Knowing that an AI agent has access to a sensitive data source does not govern what happens when it retrieves content, assembles a prompt, or receives a tool response containing an injection. That enforcement happens inline, at the moment of each interaction.
Capability comparison
| Capability | Trussed | Noma | Notes |
|---|---|---|---|
| AI asset discovery | — | ✓ | Noma leads on enterprise AI inventory including shadow AI and MCP servers |
| AI-SPM / posture mgmt | — | ✓ | Noma provides risk scoring, compliance assessment, and policy at estate level |
| Agentic risk mapping | — | ✓ | Noma ARM visualizes blast radius and cascading agent-to-agent risk |
| Runtime enforcement | ✓ | ◐ | Trussed proxy-based inline enforcement; Noma blocking vs. alerting requires verification |
| Prompt injection | ✓ | ✓ | Both confirmed; Noma via runtime protection; Trussed via inline proxy |
| Data leakage protection | ✓ | ✓ | Both address data leakage; Trussed more granular for PHI and code secrets |
| PII detection | ✓ | ✓ | Both confirmed; protection at each MCP hop required |
| PHI detection | ✓ | ◐ | Trussed confirmed; Noma PHI specifics require verification |
| Code secret detection | ✓ | ◐ | Trussed runtime detection; Noma supply chain scanning confirmed; runtime overlap unclear |
| Source code provenance | ✓ | — | Trussed-unique runtime capability; Noma not confirmed |
| Unicode manipulation | ✓ | ◐ | Trussed confirmed; Noma runtime scope requires verification |
| Language authenticity | ✓ | — | Trussed-unique adversarial evasion capability |
| System prompt leakage | ✓ | ◐ | Trussed confirmed; Noma coverage in runtime protection requires verification |
| AI red teaming | — | ✓ | Noma automated adversarial testing; not a Trussed primary focus |
| Supply chain security | — | ✓ | Noma scans MCP servers, open-source components, model integrity |
| Compliance management | ✓ | ✓ | Noma framework alignment and reporting; Trussed per-interaction audit evidence |
Assessment
For enterprises requiring per-interaction enforcement across MCP tool chains, Trussed provides the inline governance layer that Noma's posture management does not. Noma addresses the discovery and visibility problem; Trussed addresses the enforcement problem. Complete MCP security requires both layers.
Where Trussed goes further
- Inline per-interaction enforcement. Trussed operates as a proxy in the active request path, enforcing policies on each individual interaction, blocking, modifying, masking, rerouting, or escalating violations in real time.
- Advanced adversarial controls. Source code provenance, language authenticity analysis, unicode manipulation detection, and code secret detection in runtime outputs.
- PHI and regulated-industry data controls. Confirmed PHI detection and SOC 2 Type II and ISO 27001 certifications at the per-interaction enforcement layer.
- Governance-grade audit evidence generation. Structured audit records for every governed interaction, providing the per-interaction evidence trail required by regulated-industry auditors.
Where Noma Security has specific strengths
- Enterprise-wide AI discovery and shadow AI detection. Continuous discovery of all AI models, agents, pipelines, and MCP servers, including those deployed without security team knowledge.
- Agentic Risk Map and blast radius visualization. Mapping agent-to-agent connections, MCP server access, cross-system dependencies, and permission chains.
- Supply chain security for AI. Scanning MCP servers, open-source components, and AI pipeline inputs for vulnerabilities and poisoned data.
- Automated AI red teaming. Automated adversarial testing that identifies vulnerabilities before they are exploited.
When to choose each platform
Choose Noma Security when
- Comprehensive visibility into deployed AI is the priority
- Agent-to-agent blast radius mapping is a CISO-level requirement
- Pre-deployment supply chain security is needed
- Framework alignment with EU AI Act, NIST AI RMF, or OWASP LLM Top 10 is required
Choose Trussed when
- Per-interaction enforcement controls governing every MCP tool call are required
- Advanced adversarial controls are needed
- PHI detection and regulated-industry certifications are mandatory
- Governance-grade per-interaction audit trails are required
