Is Slack HIPAA Compliant? Enterprise Grid Requirements Explained
Slack is widely used for team communication, but HIPAA compliance is only available on Slack Enterprise Grid — the highest tier. Free, Pro, and Business+ plans do not offer a BAA and cannot be used to transmit or discuss protected health information. This guide explains what is required to use Slack in a HIPAA-compliant manner.
Slack is HIPAA compliant ONLY on the Enterprise Grid plan with a signed BAA from Salesforce (Slack's parent company). Free, Pro, and Business+ plans do not qualify. Enterprise Grid provides the encryption, DLP, and admin controls required for HIPAA.
Compliance Assessment
Slack encrypts data in transit (TLS 1.2) and at rest (AES-256) on all plans. Enterprise Grid adds Slack Enterprise Key Management (EKM) for customer-managed keys.
BAA is available only on Enterprise Grid. You must contact Salesforce/Slack sales to execute the BAA.
Enterprise Grid offers SSO (SAML), SCIM provisioning, session management, domain claiming, and granular admin roles. Lower tiers have limited controls.
Enterprise Grid provides an Audit Logs API for tracking user actions, file access, and admin changes. Not available on lower tiers.
Enterprise Grid supports DLP integrations and native message retention policies. Lower tiers lack DLP capabilities.
Enterprise Grid allows custom retention policies per channel and organization-wide. Lower tiers have limited retention controls.
EKM allows you to control encryption keys via AWS KMS, enabling key revocation if needed. Only available on Enterprise Grid.
Enterprise Grid allows restricting who can create channels, invite external guests, and share files to prevent PHI leakage.
Slack apps and integrations are not covered under the BAA. Each integration handling PHI needs its own compliance assessment.
Slack offers data residency for Enterprise Grid customers, allowing you to choose where messages and files are stored.
Business Associate Agreement (BAA)
Slack (owned by Salesforce) offers a BAA exclusively for Enterprise Grid customers. The BAA covers Slack messaging, file sharing, and Slack Huddles within the Enterprise Grid environment. It does not cover third-party Slack apps or integrations. Contact Salesforce sales to negotiate and execute the BAA.
How to Make Slack HIPAA Compliant
Subscribe to Slack Enterprise Grid and execute a BAA with Salesforce/Slack.
Enable SSO (SAML) and enforce two-factor authentication for all users.
Configure Enterprise Key Management (EKM) with AWS KMS for customer-controlled encryption keys.
Set up custom message and file retention policies that meet HIPAA's six-year requirement.
Restrict third-party app installations to IT-approved, HIPAA-compliant integrations only.
Configure DLP policies to detect and prevent sharing of PHI patterns in messages.
Limitations
- Free, Pro, and Business+ plans do not offer BAAs and cannot be used with PHI.
- Enterprise Grid is significantly more expensive than other Slack tiers (custom pricing, typically $12+/user/month).
- Third-party Slack apps and bots are not covered under the Slack BAA.
- Slack Connect (external channel sharing) introduces compliance risks when communicating with outside organizations.
- Slack does not provide native PHI detection — DLP requires third-party integrations.
