xAI launches secure vault for Grok Enterprise customers

A dedicated space for secrets

Elon Musk recently confirmed that Grok now includes a secure vault designed for sensitive information. This feature is intended for business and enterprise users who need to interact with an AI assistant while maintaining strict data privacy. It creates a distinct environment for confidential files and queries.

The Enterprise Vault functions as an isolated data environment within the xAI platform. It is separated from the standard consumer infrastructure that powers the general version of Grok. This separation ensures that private corporate data does not mingle with public interactions.

As BASENOR reported, the vault provides both physical and logical isolation for its users. This means the data does not just sit in a different software folder but actually runs on a dedicated data plane. This architecture is built to satisfy the high security requirements of large organizations.

How the encryption works

Security in the vault is managed through application-level encryption. One of the most important features for large companies is the support for customer-managed encryption keys, or CMEK. This allows the organization to hold the keys that lock and unlock the data rather than letting xAI manage them.

Because the customer controls the keys, xAI cannot access the information within the vault without permission. This level of control is a standard requirement for many regulated industries. It provides a layer of trust for companies handling sensitive legal, financial, or medical records.

The system also ensures that data is encrypted both while it is moving and while it is sitting on a server. These protections are isolated from other organizations using the platform. This ensures that one company's data remains completely invisible to another company using the same service.

Who can access the vault

The Enterprise Vault is not a feature available to everyone who uses Grok. It is strictly exclusive to Grok Enterprise customers. Users on the free tier or the standard X Premium subscription do not have access to this isolated environment.

The Grok Business tier, which costs $30 per seat per month, also does not include the vault. To access the Enterprise tier and its vault features, companies must engage directly with xAI for pricing. This suggests a high-touch sales model for the most secure features.

While the vault is for large companies, the broader Grok Business and Enterprise tiers launched via a self-serve portal in late 2025. These tiers were made generally available around January 2, 2026, providing a path for various sizes of businesses to adopt the tool.

Compliance and model access

xAI has designed the platform to meet several major regulatory requirements. The vault and the enterprise plans comply with SOC 2, GDPR, and CCPA. These are standard frameworks that govern how data is handled, protected, and deleted across different regions.

Enterprise customers also receive advanced administrative tools to manage their accounts. These include custom role-based access control and flexible organizational structures. They also get advanced audit and security capabilities that are necessary for regulated workflows.

Users on the Enterprise tier get access to scalable versions of the most advanced models. This includes Grok 3, Grok 4, and Grok 4 Heavy. While Grok 5 was launched in late 2026, it has not been officially confirmed if it is fully integrated into the vault-protected workflows yet.

The training policy

A major concern for many businesses is whether their private data will be used to improve the AI. xAI has taken a firm stance on this issue for its paid tiers. The company's official position is: "Your data stays yours: no training on it, ever."

This policy applies to both the Grok Business and Enterprise tiers. It means that any information stored in the vault or processed through these plans is excluded from the model's learning process. This is a critical distinction from many free AI services that use user input to refine their algorithms.

For everyday users on X Premium, the vault remains unavailable for now. However, the push toward enterprise-grade security suggests a shift in how xAI views its platform. It is moving from a consumer chatbot toward a credible tool for professional and industrial use cases.
