Onyx Security — Agent Audit

ESTIMATED SCORE — NOT VERIFIED

This assessment is based solely on publicly available documentation, marketing materials, and product announcements. Onyx Security has not submitted to AgentGoverning for independent adversarial verification. This score is an estimate only and may not reflect actual platform capabilities. Onyx Security is invited to submit for formal assessment at framework@agentgoverning.com. Estimated scores carry no certification status.

How This Score Is Calculated

This estimated score reflects publicly documented agent deployment governance capabilities assessed across 10 capability categories against the 508 Agent Audit dimensions of AGS v2.2:
• Mandate & autonomy (27 dims)
• Agent orchestration (65 dims)
• Trust & identity (30 dims)
• Detection & containment (35 dims)
• Financial controls (45 dims)
• Human oversight (7 dims)
• Memory & knowledge (18 dims)
• Sector-specific (180 dims)
• Other core governance (93 dims)
• Deployment & lifecycle (8 dims)

Each category scored 0–100% based on public documentation coverage. Overall score = weighted average across all 10 categories.

Based solely on publicly available documentation as of April 2026.

What This Score Means

Onyx Security's Guardian Agent supervisory layer provides genuine runtime intervention capability that scores well on detection and containment dimensions (~40% of those 35 dimensions). However, Onyx is positioned as a security product rather than a governance platform based on its public documentation. It monitors agent behaviour for threats and vulnerabilities rather than governing agent behaviour as an autonomous entity. Financial controls, mandate enforcement, multi-agent orchestration governance, memory/RAG governance, and all sector-specific agent governance dimensions are outside its documented scope. The majority of Agent Audit dimensions are not evidenced in public documentation for this platform..

Key Strengths

AG-039

Deception Detection

Guardian Agent supervisory layer provides genuine runtime deception detection capability, monitoring agent outputs for deceptive or misleading patterns.

Score: 2 / 3

AG-022

Behavioural Monitoring

Strong behavioural boundary monitoring with runtime anomaly detection and intervention capabilities for deployed agents.

Score: 2 / 3

AG-003

Adversarial Coordination Detection

Basic adversarial coordination detection through security-focused monitoring of agent interaction patterns.

Score: 1 / 3

The following gap analysis is based on publicly available documentation only. These are estimated structural gaps, not verified findings. Onyx Security may have implemented controls not visible in public documentation.

Critical Gaps

AG-057

Delegation Chain Governance

No delegation chain governance. Tracking or governance of how authority is delegated between agents in multi-agent systems is not evidenced in public documentation.

Score: 0 / 3 — Structurally Absent

AG-058

Inter-Agent Trust Attestation

No inter-agent trust handshake or attestation framework. Security monitoring does not extend to governance-level trust between agents.

Score: 0 / 3 — Structurally Absent

AG-784

Adaptive Threat Response

No adaptive threat response framework specifically designed for agent-level governance threats as opposed to traditional cybersecurity threats.

Score: 0 / 3 — Structurally Absent
