Cyber Essentials vs ISO 27001: Which Does Your UK Business Need?
Quick Summary
| | Cyber Essentials | ISO 27001 | |---|---|---| | Governing body | NCSC / IASME | ISO / BSI | | Scope | 5 technical controls | Full ISMS | | Time to certify | 1–4 weeks | 6–18 months | | Cost (SME) | £300–£5,000 | £8,000–£50,000+ | | Government contracts | Often required | Valued | | International recognition | UK primarily | Global |
What Is Cyber Essentials?
UK government-backed scheme covering 5 controls:
- Firewalls
- Secure configuration
- User access control
- Malware protection
- Patch management
Two tiers: Basic (self-assessment, ~£300–£500) and Plus (independently verified, £1,500–£5,000).
Who should get it: Any UK business bidding for government contracts, SMEs wanting baseline cyber hygiene, businesses seeking cyber insurance discounts.
What Is ISO 27001?
International standard for Information Security Management Systems (ISMS). 93 controls across 4 themes. Requires building a systematic framework for managing information security risk.
Who should get it: Businesses supplying enterprise clients who require it contractually, SaaS companies selling to enterprise, organisations with high data sensitivity.
Can You Have Both?
Yes — many UK businesses pursue CE first, then ISO 27001 as they grow. The five CE controls map directly to several ISO 27001 controls.
How Gridisys Supports Both
- Cyber Essentials: Evidence packs for CE Plus assessments, user access control monitoring
- ISO 27001: Continuous logging (Annex A controls), incident response support
