For SMBs scaling into enterprise

ISO 27001 readiness

Honest framing of when an SMB really needs ISO 27001, the rough timeline and cost, and what an Annex A statement looks like.

ISO/IEC 27001 is the international standard for information security management systems (ISMS). Unlike Cyber Essentials, it's not a checklist of technical controls — it's a documented, audited management system you operate continuously.

Most UK SMBs do not need ISO 27001. The exceptions are companies whose customers (typically large enterprises, financial services or the public sector) explicitly require it as part of supplier due diligence.

This pillar collects readiness guidance, gap-analysis templates and decision frameworks so you can decide honestly whether to pursue it.
