AI Governance Readiness
Enterprise-Ready
Strong verifiable security and governance posture.
Readiness Breakdown deterministic · evidence-only
- Independent Certification SOC 2 / ISO certifications confirmed via the vendor's trust portal (ISO 27001, SOC3). Audit report available under NDA — standard enterprise practice.
- Vendor-Stated Compliance Vendor states (cited, not independently audited): BAA Available (HIPAA), GDPR, HIPAA, ISO 27001, SOC 2.
- Customer-Data Training Enterprise terms: does NOT train on customer data (consumer/free tiers may differ — see breakdown).
- Data Processing Agreement A Data Processing Agreement is published and tracked.
- Breach History No known breaches in Have I Been Pwned.
- Vulnerability Exposure No product identity match in vulnerability databases — not assessed.
- Email Spoofing Protection (DMARC) DMARC enforced — domain spoofing mitigated.
- Vulnerability Disclosure Policy Publishes a security.txt disclosure policy (RFC 9116).
- Web TLS Certificate Valid TLS certificate in place.
- Legal Transparency 11 legal/policy documents publicly tracked.
Score is normalized over assessed components only — “unknown” items
are shown but never silently counted against the vendor.

Free / Pro:
does not train
Slack does not use Customer Data (messages, files) to train LLMs; generative AI runs on off-the-shelf models hosted in Slack's own VPC with no provider access.

Enterprise:
does not train
Generative AI models are never trained on customer data unless the customer gives affirmative opt-in consent. (Traditional ML like recommendations: opt-out via email.)

Certifications Available Under NDA / Trust Center attested · report gated
| Certification | Status | Trust Center |
|---|---|---|
| ISO 27001 | Available via Trust Center | https://slack.com/security |
| SOC3 | Available via Trust Center | https://slack.com/security |
An independent audit report exists but is gated behind an NDA or trust-center registration. Request it directly via the vendor's trust center. These count as partial assurance — stronger than a vendor claim, but not an open third-party attestation.
Vendor-Claimed, Not Independently Verified treat as unconfirmed
| FEDRAMP LOW | Claimed — not independently verified | https://slack.com/security |
| FEDRAMP MODERATE | Claimed — not independently verified | https://slack.com/security |
| ISO 27017 | Claimed — not independently verified | https://slack.com/security |
| ISO 27018 | Claimed — not independently verified | https://slack.com/security |
| ISO 27701 | Claimed — not independently verified | https://slack.com/security |
These appear on the vendor's site but we could not confirm an independent audit report. Request the underlying attestation before relying on them.

How to Obtain Non-Public Documents
These documents were not found at a public URL — which is normal. Many are provided on request, only on enterprise plans, or via the vendor's trust portal. Here is where each lives and what to do to get it.
| Document | Availability | How to obtain |
|---|---|---|
| Business Associate Agreement (BAA) | On request (HIPAA only) | A BAA is required only when processing PHI under HIPAA and is almost never published publicly. Request one from the vendor's compliance/legal team during enterprise onboarding — it is typically signed under NDA. Trust center → |
| Service Level Agreement (SLA) | Enterprise tier | A formal uptime/support SLA is generally offered only on enterprise/paid plans and attached to the order form. Ask sales for the SLA exhibit or check the enterprise pricing page; the trust center often summarises uptime commitments. Trust center → |
