Secure Your LangChain Agents
LangChain makes it easy to build AI agents. Agent Action Firewall makes them safe for production. Add enterprise-grade security without rewriting your agent code.
The Production Gap
LangChain is incredible for prototyping agents. But when you deploy to production, you need answers to questions LangChain doesn't address:
Without AAF
- • What if the agent tries to delete production data?
- • How do we audit every action for compliance?
- • Can we require approval for high-risk operations?
- • What happens if an agent goes rogue?
With AAF
- • OPA policies block dangerous actions automatically
- • Hash-chained audit trail for every action
- • Human-in-the-loop approval workflows
- • Usage limits prevent runaway agents
Simple Integration
Wrap your LangChain tools with AAF's SDK. No major refactoring required.
from langchain.agents import initialize_agent from langchain.tools import Tool agent = initialize_agent(tools=[my_dangerous_tool], llm=llm)
from langchain.agents import initialize_agent from aaf import AAFClient, wrap_tool aaf = AAFClient(api_key="your-key") protected_tool = wrap_tool(my_dangerous_tool, aaf) agent = initialize_agent(tools=[protected_tool], llm=llm)
What AAF Adds to LangChain
Policy Enforcement
OPA/Rego policies evaluate every tool call. Block dangerous actions before they execute.
Human Approval
Route sensitive actions to Slack, Teams, or email for human approval before execution.
Audit Trails
Cryptographic hash-chaining ensures tamper-evident logs. Export Proof Packs for compliance.
Usage Limits
Set daily/weekly/monthly action limits per agent. Get alerts at 80% and 95% thresholds.
DLP Scanning
Detect PII, API keys, and sensitive data in action payloads before they leave your system.
Dry-Run Mode
Test policies without affecting production. See what would be blocked before deploying.
LangChain + AAF Use Cases
ReAct Agents with Tool Use
Your ReAct agent decides to call external APIs. AAF ensures it can only call approved endpoints and requires human approval for actions above certain thresholds.
SQL Agents
LangChain's SQL agent generates queries. AAF blocks DROP/DELETE statements, requires approval for UPDATE on production tables, and logs every query.
Multi-Agent Systems (LangGraph)
Complex LangGraph workflows with multiple agents. AAF provides a single control plane for policy enforcement across all agents in the graph.
