Orchestration
Exogram + LangGraph
“State machines are not security boundaries.”
What LangGraph Does
- •LangGraph allows developers to build stateful, multi-actor applications with LLMs.
- •It excels at cyclical workflows, treating agents as nodes in an execution graph.
- •Manages internal application state well, but does not explicitly govern external execution safety.
- •If a LangGraph node proposes a destructive payload, the graph executes it.
What Exogram Does
- ▸Exogram governs the execution output of any LangGraph node.
- ▸While LangGraph manages the state machine, Exogram validates the external actions (tool calls) generated during that state cycle.
- ▸Integration is immediate: wrap the tool execution node with the Exogram evaluator. 0.07ms latency per node execution.
Key Differences
| Dimension | LangGraph | Exogram |
|---|---|---|
| Primary Role | State orchestration routing | Admissibility validation |
| Cyclical Risk | Executes whatever the node proposes | Mathematically blocks invalid mutations |
The Verdict
Use LangGraph to coordinate your agent's state machine. Use Exogram to ensure those state transitions do not result in destructive database mutations.
Interception Latency Benchmark
Unlike standard LLM-based guardrails that invoke external APIs on every single tool execution, Exogram compiles policies to execute in-memory inside the client runtime.

Frequently Asked Questions
Does Exogram replace LangGraph?
No. LangGraph decides *when* an agent should take an action based on graph topology. Exogram decides *if* that action is allowed to execute based on deterministic policy.
