Is Slack AI ISO 27001 certified?

Yes

Salesforce · Productivity

Yes. Salesforce is ISO/IEC 27001 certified for Slack AI, the international information-security management standard.

What we checked

This assessment separates the consumer product from any business plan. It uses the vendor documents linked below; an unverified item is not a pass.

ISO/IEC 27001: Confirmed; Salesforce reports ISO/IEC 27001 certification. Ask for scope and current certificate dates before treating it as supplier assurance.
SOC 2: Confirmed; Salesforce also reports a SOC 2 attestation, which can complement but does not replace ISO scope evidence.
Default data training: No by default; Slack states Customer Data is never used to train third-party LLMs, and generative AI models are not developed using Customer Data; this applies across tiers (Slack AI is not offered on free/consumer tiers).
Business-tier training: No by default; For paid/enterprise use, Slack AI uses off-the-shelf LLMs hosted within Slack's own AWS trust boundary that do not retain or train on Customer Data, using RAG to send only inference-time data.

Practical risk: The 'no training' guarantee covers generative LLMs, but Slack's non-generative machine-learning features have historically processed customer messages on an opt-out (not opt-in) basis, so admins must proactively review AI/ML data settings rather than assume default protection.

How to make a decision

Check the precise account tier, written contract and intended data before approving Slack AI. A security certification, DPA or setting can apply to only part of a vendor's service. Keep the source links with your supplier review and revisit them when the vendor changes its terms.
