Reviewer brief

As of 2 Nov 2026, CertReports holds 1 registry-verified row and 1 expired row for Slack, drawn from FedRAMP Marketplace and the Data Privacy Framework list. Slack is listed in the FedRAMP Marketplace for FedRAMP (FedRAMP Authorized), dated 20 May 2020, assessed by Schellman Compliance, LLC. Slack previously appeared with EU-US Data Privacy Framework evidence, but the listing is no longer active and CertReports found no renewal as of 2 Nov 2026. No public evidence was found for SOC 2, ISO/IEC 27001, HIPAA and GDPR as of 2 Nov 2026; that is a gap in the public record, not a finding of non-coverage, and the vendor can supply it under NDA.
