ISO 27001 Certification: ISMS & Buyer Sharing
As of the ISO Survey 2023, there were 71,549 valid ISO 27001 certificates across 175 countries — making it the second most adopted ISO management system standard after ISO 9001. In a 2024 Vanta survey, 78% of companies reported that ISO 27001 certification directly helped them close deals faster. The transition from ISO 27001:2013 to ISO 27001:2022 completed in October 2025, and any organization still holding a certificate against the 2013 version must now recertify against the updated standard. The market message is unambiguous: in B2B procurement, ISO 27001 has become less a security posture indicator and more a market access prerequisite.
ISO 27001 is the international standard for Information Security Management Systems (ISMS). For B2B companies — SaaS platforms, IT service providers, cloud infrastructure companies, and any organization handling client data — it is the single most requested compliance credential in vendor assessments. On the Sustalium platform, we see the real bottleneck is rarely the technical controls themselves — it is the inability to produce the certificate, Statement of Applicability, and audit reports in a single verifiable package when procurement asks for them.
