LangGuard
Deterministic runtime AI governance control plane
LangGuard is a deterministic runtime AI governance control plane. Two engines work across the full agent lifecycle: SCOPE-MCP maps and compliance-classifies an agent's action surface before it ships, and Arbiter deterministically authorizes every agent action before it executes — clearing safe actions with no added latency and routing anything that crosses a Segregation-of-Duties boundary or policy threshold to a named approver. The authorization is the governance; the audit trail is automatic.
Zenity
Agentic AI security (AISPM + agent detection & response)
Zenity secures AI agents across Microsoft Copilot, low-code platforms, Salesforce Agentforce and custom clouds — discovery and posture management (AISPM), least-privilege permission analysis, and runtime detection & response (AIDR). A 2025 Gartner Cool Vendor in Agentic AI TRiSM.
How they compare
Twelve criteria that decide whether an enterprise can prove — not just hope — that its AI agents stay inside policy.
| Criterion | LangGuard | Zenity |
|---|---|---|
| Deterministic, rule-based authorization | ● | ◐ |
| Pre-execution enforcement | ● | ◐ |
| Segregation of Duties enforcement | ● | ○ |
| Excessive-agency prevention / least privilege | ● | ● |
| Design-time action-surface mapping | ● | ◐ |
| Compliance-classified tools catalog | ● | ◐ |
| Full lifecycle coverage (design-time + runtime) | ● | ● |
| Named-approver human-in-the-loop routing | ● | ○ |
| SOX / GDPR / financial-GRC control mapping & evidence | ● | ◐ |
| AI-specific standards (ISO 42001, EU AI Act, NIST AI RMF, OWASP LLM) | ◐ | ◐ |
| Immutable / tamper-evident audit ledger | ● | ◐ |
| GRC / internal-audit / IT-governance buyer fit | ● | ○ |
Where Zenity is strong
- Best-in-class agent discovery and inventory across Copilot, low-code and SaaS sprawl
- Mature AISPM with deep permission analysis and least-privilege enforcement
- Correlates build-time posture with runtime behavior — genuine lifecycle coverage
- Strong offensive research (AgentFlayer) and Gartner analyst validation
Where LangGuard pulls ahead
- The runtime engine is behavioral/anomaly detection (probabilistic), not deterministic authorization
- No Segregation-of-Duties enforcement
- Response is automated playbooks (quarantine/revoke), not named-approver routing
- ISO 42001 and EU AI Act are not mapped; audit-immutability claims are inconsistent
- Sells to the CISO / AppSec org, not GRC or internal audit
The bottom line
Zenity is a capable agent detection & response. But securing how an agent operates is not the same as governing what it is allowed to do. LangGuard makes a deterministic, rule-based authorization decision on every action before it executes — enforcing Segregation of Duties, routing risky actions to named approvers, and emitting audit-grade SOX/GDPR evidence. It is the governance control plane that sits above the layer Zenity operates in.
