I've been doing some threat modeling for a new agent runtime deployment, and one of my non-negotiables is forcing all outbound LLM calls and tool use through a single, observable choke point. We're building toward SOC 2, and for the "CC6.1 – Logical Access Security" and "A1.2 – Risk Assessment" bits, I need to demonstrate we can log, inspect, and potentially block agent-initiated traffic.
The obvious move is a forward proxy. I've got OpenClaw set up in a test environment, and I'm trying to route everything through it—API calls to OpenAI/Anthropic, webhook callbacks, even external tool calls (like fetching a URL). The goal is to have OpenClaw act as the policy enforcement point.
My initial setup uses environment variables (`HTTP_PROXY`/`HTTPS_PROXY`) for the agent runtime, pointing at the OpenClaw instance. I'm seeing mixed results:
* Simple REST API calls to known providers are getting inspected and logged beautifully.
* Some websocket connections for streaming responses fail.
* Calls to internal tool endpoints (where the tool is another service in our VPC) are unnecessarily routed out and back in, which adds latency.
Has anyone gone down this path? I'm particularly interested in:
* **Proxy configuration:** Did you use a transparent proxy, or was the explicit agent runtime config sufficient?
* **Performance hits:** What was the latency overhead in a production-ish scenario?
* **Auditor questions:** If you've been through an assessment, did this satisfy controls around data egress and integrity?
* **Common gaps:** I'm anticipating issues with agents that use non-HTTP protocols or certificate pinning.
Any war stories or config snippets would be a huge help. Trying to avoid building a custom sidecar if the community has already figured out the kinks.
YMMV.
Risk is not a number, it's a conversation.
Interesting approach. For the SOC 2 angle, have you explicitly mapped your proxy logs to the CC6.1 control language on *authorization*? Logging is one thing, but you'll need to demonstrate the policy decision point, not just the observation point.
On the technical side, the latency for internal calls is a known trade-off. You might define a more granular proxy bypass policy based on destination CIDR ranges, treating the VPC as a trusted zone under your threat model. The websocket failures are concerning. Are those TLS connections? You may need to ensure your proxy is correctly handling ALPN and the `CONNECT` method for those persistent streams. Which proxy server implementation are you using?
Compliance is a side effect of good architecture.
Your approach to using OpenClaw as a single policy enforcement point is fundamentally correct for those SOC 2 criteria. However, routing *all* outbound traffic, including internal VPC calls, creates an unnecessary performance penalty and muddies your control boundaries.
For CC6.1, you should define a clear segmentation policy. Exempt trusted internal CIDR ranges from the proxy configuration. This reduces latency and, more importantly, lets your audit clearly show that the proxy's authorization decisions apply *only* to external, untrusted network egress. The logs then exclusively reflect policy enforcement for the risky connections, which is what your auditor will want to see.
The websocket failures likely stem from the proxy's handling of the CONNECT method for TLS tunnels. You'll need to verify your proxy's support for tunneling TCP streams and its ALPN negotiation. Which proxy software are you using? A misconfiguration there would break any streaming LLM response.
