Kyde vs Noma Security
Noma set out to be the Wiz of AI security and is executing on that ambition: a platform that now spans discovery and posture management, agentic access control, red teaming and a runtime protection module that monitors every prompt, response and tool call and enforces policies in real time. So this is not a posture scanner versus a gateway. It is a broad AI security lifecycle platform versus a deep, single-purpose governance boundary. Noma protects your AI estate against threats across its lifecycle. Kyde governs what your agents may do at one unavoidable point, deterministically, and produces the tamper-evident record that proves it. Breadth versus depth, threat model versus liability model.
Choose Noma if
- →You want one platform across the AI lifecycle: inventory, misconfigurations, supply chain, red teaming and runtime threat protection
- →Your primary lens is security: attacks, injections, data egress, rogue outputs
- →You have a large internal AI/ML estate (models, pipelines, agents) that needs posture hygiene
Choose Kyde if
- →Your primary lens is liability: what may this agent do, did it stay inside its mandate, and can you prove it to an outside party
- →Enforcement must be deterministic, not detection-based, for actions with legal or financial consequence
- →You need vendor-independent, tamper-evident records in your own perimeter, with EU sovereignty
| Noma Security | Kyde | |
|---|---|---|
| Category | AI security lifecycle platform (posture to runtime) | Agent governance boundary (enforcement plus evidence) |
| Runtime model | Real-time threat protection: detects and blocks injections, sensitive data egress | Deterministic mandate: allowed executes, everything else does not |
| Decision basis | Security detection and policy on observed content | Policy on structural facts: agent, tool, endpoint, history |
| Coverage precondition | Platform integration into your AI estate | Network egress: covers agents that never integrated anything |
| Audit trail | Security telemetry and logs | Hash-chained, vendor-independent ledger (Ed25519 signing on Enterprise) |
| Extras | AISPM, red teaming, agentic access control | Coverage reporting, compliance evidence exports |
| EU sovereignty | US and Israel based company | Edge enforcement in your perimeter, air-gapped available |
| Regulatory anchor | AI security posture and threat defense | NIS-2, DORA, EU AI Act evidence duties |
What Noma does well
Noma earned its reputation quickly: the AI estate of a modern enterprise is a sprawling, misconfigured attack surface, and Noma's lifecycle approach attacks that honestly, from discovering what exists, through posture and supply chain checks, to red teaming and now runtime protection. Blocking prompt injection and sensitive data egress in real time across the estate is real value, and their agentic access control shows they understand that agents change the identity problem too. If your question is "how exposed is our AI estate and who is attacking it," Noma is a strong, comprehensive answer.
Threats versus mandates
Runtime threat protection asks: does this look like an attack or a leak? That is a detection question, answered probabilistically, tuned for coverage. Agent governance asks a narrower question that must not be probabilistic: is this action within this agent's mandate? A wire transfer to a new payee at 2 AM is not an injection and leaks nothing, and no threat engine flags it. It is simply outside what that agent was mandated to do. Kyde blocks it because the mandate says so, and the ledger shows exactly which policy version said so.
Integration versus boundary follows the same logic. A lifecycle platform is as complete as its integration into your estate. The agents that worry auditors most are the ones outside the estate map: the vendor tool, the script on a VM, the experiment in production. Kyde does not need to know your estate to govern them, because they all cross the same egress.
Security telemetry versus legal evidence
Noma's logs serve the SOC. Kyde's ledger serves the general counsel: hash-chained, held in your perimeter, independent of every vendor including us. Under NIS-2 and DORA, the difference between "our security tool logged it" and "here is the tamper-evident record" is the difference between an explanation and a defense.
Can you run both?
Cleanly, yes: Noma for AI estate security across the lifecycle, Kyde as the deterministic governance boundary and evidence layer for agent actions. The stacks meet at the same buyer and answer different questions. If you must sequence, sequence by exposure: liability-heavy agents first means boundary first.
Noma has runtime protection now. Is that not enforcement?
It is threat enforcement: blocking attacks and leaks it detects. Mandate enforcement is a different primitive: bounding what an agent may do even when nothing looks like an attack. Audits ask about the second kind.
Do we need a boundary if our estate is fully mapped in Noma?
Estate maps age fast. A week of recorded traffic shows you what crosses your egress that the map missed. If the answer is nothing, that certainty was free.
Which one satisfies EU AI Act logging duties?
Article 12 wants automatic, tamper-evident logs for high-risk systems. Cryptographic hash chains are the only method that reliably survives regulator scrutiny, and that is what Kyde produces, with Ed25519 signing on the Enterprise tier. High-risk enforcement begins December 2, 2027. NIS-2 and DORA apply today.
