Hi everyone! I've been diving into LangGraph for a side project, and I'm really impressed by how it helps structure agent workflows. It feels like it could be a game-changer for automating some of our internal processes.
My team is now exploring a more serious application: a patient intake and follow-up coordinator. This would involve handling sensitive patient data. I know the big question is always HIPAA compliance.
I've seen that some LLM providers (like OpenAI and Anthropic) offer BAA agreements for their enterprise tiers. My main concern is LangGraph itself. Since it's a framework for building the workflows, does it store or transmit data in a way that could be a problem? If we're using compliant LLM APIs and hosting everything in our own secure cloud (like AWS), is LangGraph "invisible" from a compliance perspective, or are there specific things in its architecture we need to lock down?
I'm also curious if anyone has actually gone through a security review for a healthcare app built with it. Were there any red flags or specific configurations you had to implement?
Basically, I love the tool, but I don't want to steer us into a compliance nightmare. Any guidance from those who've looked into this would be so appreciated!
That's a critical distinction to make. LangGraph is a framework, so it doesn't inherently store or transmit data to a third-party service. The data flow is dictated by your own infrastructure and the integrations you build.
Your approach of using BAA-covered LLM APIs and your own secure hosting is the right path. The compliance burden then falls on your application's architecture. You'll need to be meticulous about how you manage state, logs, and any persistence within your workflow. For instance, if you're using LangGraph's persistence features, you must ensure that storage backend (like your own database) is configured for encryption and access controls that meet HIPAA standards.
I haven't been through a review for a healthcare app with it myself, but I'd be looking very closely at any telemetry or logging the framework might do by default. Even if it's just error reporting, you'd need to disable or redact any PHI. Has anyone on your team done a full code audit to see where data actually touches the framework?

The code audit point is critical, but I think you're giving the framework too much of a free pass. The "just a framework" defense is how teams end up with invisible data pipelines they never accounted for.
You need to check more than just telemetry. How does it handle retries when your BAA-covered API call fails? Does it dump the entire patient record into an error object that gets logged to a local file? What about the memory of the agents within a graph - is that state being serialized somewhere temporarily, maybe to disk, before it's shipped to your "compliant" database? The persistence abstraction is a leaky one.
I've seen this movie before with other "orchestration" tools. The default configurations are built for developer convenience, not for locking down PHI. Your team will be on the hook for every single default setting and what it does with a string containing a patient name. Good luck.
