How do we contact LangChain sales and start an Enterprise security review (hybrid/self-hosted in our VPC, security questionnaire)?

When you’re ready to evaluate LangChain for a hybrid or self-hosted deployment in your own VPC, the fastest path is to connect with the sales team directly and kick off an Enterprise security review in the same motion. That usually means three things: getting to the right contact form, signaling that you’re interested in hybrid or self-hosted, and sharing your security questionnaire and requirements so we can scope deployment options.

Quick Answer: Use the LangChain contact form to reach sales, explicitly note that you need an Enterprise security review for hybrid or self-hosted in your VPC, and attach or link your security questionnaire. From there, the team will coordinate security, legal, and technical review in a structured evaluation process.

The Quick Overview

• What It Is: A guided process to engage LangChain sales, evaluate Enterprise security and deployment options (cloud, hybrid, or self-hosted), and complete your security questionnaire for LangSmith and Fleet/Agent Builder.
• Who It Is For: Security-conscious teams—often in regulated or large enterprises—planning to run LangSmith and related services in a dedicated environment, hybrid architecture, or their own VPC.
• Core Problem Solved: You need clarity on where data lives, how it’s secured, and how LangChain fits your compliance posture before you can move from a proof-of-concept to production agents.

How It Works

The Enterprise sales and security review process is designed to match your architecture and compliance bar without slowing your build–observe–evaluate–deploy loop for agents.

There are three main phases:

1. Initiate contact with sales:

   • Go to the LangChain contact page: https://www.langchain.com/contact-sales.
   • Share basic company details and clearly state that you want an Enterprise security review for hybrid or self-hosted in your VPC.
   • Include context about your use case, expected scale, and any hard compliance constraints (e.g., data residency, VPC-only, no external SaaS).

2. Align on deployment model and scope:

   • A sales or solutions person will confirm whether you’re looking at:
     • Cloud: LangChain-managed in LangChain’s Cloud (US or EU).
     • Hybrid: LangChain SaaS control plane + self-hosted data plane.
     • Self-Hosted: LangSmith and related services deployed into your VPC (AWS, GCP, or Azure).
   • You’ll walk through data flows, model choices, and where different components run.
   • This is where you share your security questionnaire, standard addenda (DPA, BAA if applicable), and any specific requirements (SSO/SAML, SCIM, RBAC/ABAC, audit logs, logging standards, etc.).

3. Security, legal, and technical review:

   • LangChain’s team reviews your questionnaire and maps answers to concrete controls:
     • Data storage locations (e.g., GCP us-central-1 or europe-west4 vs your own VPC).
     • Auth and access controls (SSO/SAML, RBAC, org roles).
     • Logging, auditing, and encryption standards.
   • In parallel, you refine architecture for your hybrid or self-hosted deployment:
     • For Enterprise, LangSmith can run directly in your Kubernetes cluster in AWS, GCP, or Azure so data never leaves your environment.
   • Once both sides are comfortable with security and deployment, you move into a plan selection and implementation phase.

Features & Benefits Breakdown

Core Feature	What It Does	Primary Benefit
Contact Sales & Enterprise Scoping	Central intake through the LangChain sales form with clear flags for hybrid/self-hosted and security review needs.	Ensures you’re routed to the right sales and technical contacts quickly, with context about your VPC and compliance requirements.
Hybrid & Self-Hosted Deployment Options	Offers LangSmith and related components in cloud, hybrid, or self-hosted deployments, including on your Kubernetes cluster.	Lets you keep sensitive data in your environment while still using LangChain’s agent engineering platform.
Structured Security Questionnaire Process	Uses your existing security questionnaire and documentation workflow to capture requirements and map them to LangChain’s controls.	Speeds up security approvals and procurement by aligning on data residency, access control, and encryption up front.

Ideal Use Cases

• Best for enterprises needing VPC isolation: Because hybrid or self-hosted deployment lets you run LangSmith in your own AWS, GCP, or Azure environment, ensuring data never leaves your control while you still get full tracing, evaluation, and deployment capabilities.
• Best for teams with strict compliance and security review processes: Because the Enterprise review workflow is built around your security questionnaire, procurement process, and approvals, including data residency and custom SSO requirements.

Limitations & Considerations

• No direct security review without sales contact: The security and deployment review is tied to the Enterprise sales process. You’ll need to contact sales via https://www.langchain.com/contact-sales to initiate a hybrid or self-hosted evaluation and formal questionnaire review.
• Plan-dependent deployment options: Cloud (LangChain’s Cloud in US or EU) is available broadly. Hybrid and self-hosted deployments—such as running LangSmith in your Kubernetes cluster—are typically Enterprise plan options and require scoping, contract, and implementation planning.

Pricing & Plans

LangChain offers plans for teams at different stages, with deployment options expanding as you move into Enterprise:

• Cloud Plans (Team / Business): Best for teams that can use LangChain’s managed cloud (US or EU) and want to start quickly with tracing, evaluation, and deployment without owning the underlying infra.
• Enterprise / Self-Hosted Plans: Best for organizations that need hybrid or fully self-hosted deployments in their own VPC, stricter data residency controls, extended retention, and deeper security and procurement review.

To get precise pricing and see which plan fits your hybrid/self-hosted needs, use the contact form and note your deployment preference and expected scale.

Frequently Asked Questions

How do we actually contact LangChain sales to start an Enterprise security review?

Short Answer: Fill out the LangChain sales form at https://www.langchain.com/contact-sales and clearly specify that you’re requesting an Enterprise security review for hybrid or self-hosted deployment in your VPC.

Details:
On the contact form, you’ll provide:

• Name, company, work email, job title.
• Company size and global HQ region.
• A short message describing:
  • That you’re interested in Enterprise / hybrid or self-hosted.
  • That you want to run LangSmith (and optionally Fleet/Agent Builder) in your own VPC.
  • That you need to share a security questionnaire and/or complete a vendor security review.

That message is your trigger to be routed to the right combination of sales, security, and solutions engineering. From there, they’ll schedule an intro call, provide any baseline security documentation, and align on next steps for reviewing your questionnaire and requirements.

Can LangSmith run fully in our VPC, and where is data stored?

Short Answer: Yes. By default, LangSmith Cloud runs in LangChain’s GCP infrastructure (us-central-1 or europe-west4), but Enterprise customers can deploy LangSmith into their own Kubernetes cluster in AWS, GCP, or Azure so data never leaves their environment.

Details:
If you use LangSmith hosted at smith.langchain.com, data is stored in secure GCP regions (commonly us-central-1, with EU options like europe-west4). For organizations with stricter requirements:

• Self-hosted / BYOC (Bring Your Own Cloud):
  • LangSmith can be deployed into your Kubernetes cluster (AWS, GCP, or Azure).
  • This keeps traces, datasets, eval results, and agent state entirely within your VPC.
• Hybrid:
  • A SaaS control plane operated by LangChain with a self-hosted data plane for sensitive artifacts.
  • Useful when you want managed upgrades and observability but strict control of data at rest.

During the Enterprise security review, you’ll work through exactly where each component runs, how data flows, what is stored, and how retention, encryption, and access control are configured to match your policies.

Summary

To contact LangChain sales and start an Enterprise security review for hybrid or self-hosted deployment in your VPC, you go through a single front door: the sales contact form at https://www.langchain.com/contact-sales. In that form, you flag your need for an Enterprise review, specify hybrid/self-hosted and VPC requirements, and provide or request a security questionnaire. From there, LangChain’s team scopes your deployment model (cloud, hybrid, or self-hosted), aligns on data residency and controls, and works through your security and procurement process so you can ship agents into production with the right governance, not just a demo environment.
