Stateful Execution Guardrail
for autonomous agents.

Complements your LLM proxy and data catalog—formal verify, then shadow-execute against live-synced state before production side effects.

Designed for regulated environments*

SOC 2* ISO 27001*

* Compliance programs in progress — not certified claims.

Progressive enforcement beside your proxy and catalog

A complementary guardrail webhook—not a replacement choke-point. Formal verification and shadow execution decide allow, intervene, or degrade. No hard circuit breaker that turns prompt injection into a fleet DoS.

01

Complement, don’t replace

Plug into the LLM proxy and data catalog you already run. SemoxLabs is the execution policy nexus—not another routing middlebox or semantic SoT.

02

Formal, then shadow

Check capability containment against authorized bounds, then shadow-execute against live-synced clones or mocks before any production side effect.

03

Intervene or degrade

On policy violation: return deterministic feedback for self-correction, or simulate success with HITL alert. Keep benign work moving—never hard-kill the agent loop.

Core Capabilities

Stateful Execution Guardrail—formal verify, shadow-execute, and progressively enforce tool calls on your existing proxy and catalog.

Formal Verification

Translate proposed tool sequences into a formal specification. Reject plans that exceed authorized capability, information-flow, or state-change bounds—before shadow runtime.

Shadow Execution

After formal pass: run the plan against transient live-synced clones or sandbox mocks. Catch state-dependent violations syntax alone would miss—before production mutation.

Catalog-Native Policy

Construct shadow environments and policies from your incumbent data catalog—definitions, tags, glossary, column-level security. SemoxLabs does not become the semantic SoT.

Progressive Enforcement

Return allow, intervene, or degrade—never a hard circuit breaker. Simulated success plus HITL stops retry storms without crashing the agent fleet.

Proxy Webhook Integration

Stateless guardrail webhook on existing open-source or proprietary LLM proxies. Intercept tool calls, return clearance—routing, keys, and failover stay where they are.

Kernel Defense-in-Depth

For cleared live runs: optional sandbox boundary and kernel-level observability as a last line of defense if novel paths evade formal and shadow layers.

Webhook Co-Processor

Sits beside your existing proxy—not a choke-point gateway. Formal verify → shadow execute → progressive decision.
