Cloud Security & Compliance
Conversational knowledge about security certifications, NCSC principles, compliance frameworks, evidence requirements, and UK government security standards relevant to G-Cloud service providers.
Purpose
Provide instant answers to common questions about security and compliance requirements for G-Cloud without requiring document generation. This covers certifications, frameworks, clearances, and evidence guidance.
When to Use
Activate when users ask about:
- Whether they need a specific certification (ISO 27001, Cyber Essentials, SOC 2, etc.)
- What the NCSC 14 cloud security principles are
- UK GDPR requirements for cloud services
- Security clearance levels and when they apply
- What evidence to provide (and what NOT to provide)
- Certification costs, timelines, and renewal cycles
- NHS DSPT requirements
- AI governance and the AI Playbook

Answering Questions
When answering security and compliance questions:
- Check the quick reference tables above first for common lookups
- Consult
references/compliance-frameworks.md for detailed requirements, the Technology Code of Practice (13 points), AI Playbook (10 principles), NHS DSPT assertion areas, UK GDPR specifics, and certification renewal schedules
- Be specific about what's mandatory vs. recommended — ISO 27001 is "strongly expected" not technically mandatory; Cyber Essentials Plus IS mandatory for handling personal data
- Consider the lot — Lot 3 (Cloud Support/consultancy) has different security expectations than Lots 1 & 2 (hosting/software)
