What is ISO 27001?
ISO 27001 is an international standard published by the International Organization for Standardization (ISO) that specifies requirements for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS).
Official Definition
From ISO:
"ISO/IEC 27001 is the world's best-known standard for information security management systems (ISMS). It defines requirements an ISMS must meet and provides a systematic approach to managing company and customer information based on periodic risk assessments."
In plain English: ISO 27001 is a framework that shows you've built a comprehensive, systematic approach to protecting information—and an external auditor has verified it.

Why ISO 27001 Matters
1. Global Market Access
Geographic recognition:
- •Europe: De facto standard (80%+ of large companies require ISO 27001)
- •Asia-Pacific: Highly valued (especially Japan, Singapore, Australia)
- •Middle East: Required for government contracts
- •North America: Growing acceptance (competes with SOC 2)
- •Latin America: Increasing adoption
Industry requirements:
- •Finance: Required by many banks and financial institutions
- •Healthcare: Complementary to HIPAA
- •Technology: B2B SaaS companies serving global customers
- •Manufacturing: Supply chain security requirements
- •Government: Public sector contracts
Market positioning:
Without ISO 27001:
- Can't bid on European RFPs
- Excluded from government contracts
- Fails security questionnaires
- Loses to certified competitors
With ISO 27001:
- Global market access ✅
- Competitive advantage
- Premium pricing justified
- Preferred vendor status
2. Comprehensive Security Framework
ISO 27001 is more comprehensive than alternatives:
| Aspect | ISO 27001 | SOC 2 |
|---|---|---|
| Controls | 114 (Annex A) | 90-120 (depends on TSC chosen) |
| Scope | Entire organization + ISMS | Systems and processes only |
| Risk-based | Required risk assessment | Risk-informed |
| Documentation | Extensive ISMS documentation | Auditor report |
| Structure | Prescriptive framework | Principles-based |
| Flexibility | Some controls optional | Choose TSC criteria |
ISMS components (required for ISO 27001):
- •Information security policy
- •Risk assessment and treatment
- •Statement of Applicability (SoA)
- •Objectives and planning
- •Support and resources
- •Operations and performance
- •Management review
- •Continual improvement
Why this matters: ISO 27001 forces you to build a mature, sustainable security program (not just pass an audit).
3. Regulatory Alignment
ISO 27001 helps meet other requirements:
- •GDPR (EU privacy): ISO 27001 Annex A.18 covers privacy, accepted as evidence of compliance
- •HIPAA (US healthcare): Many controls overlap (access, encryption, monitoring)
- •PCI-DSS (payment cards): Supplementary to ISO 27001
- •NIS2 (EU cybersecurity): ISO 27001 demonstrates compliance
- •SOX (financial): Security controls support SOX IT general controls
Multi-framework benefit:
- •Get ISO 27001 → 60-70% of work done for SOC 2, HIPAA, GDPR
- •Evidence reuse across all frameworks
- •Single ISMS for all compliance needs
4. Insurance & Risk Management Benefits
Cyber insurance advantages:
- •Lower premiums (10-30% reduction typical)
- •Better coverage terms
- •Faster approval
- •Reduced questionnaires
Risk management:
- •Systematic risk assessment (mandatory annually)
- •Treatment plan for identified risks

Frequently Asked Questions
General Questions
Q: What's the difference between ISO 27001 and ISO 27002?
A: ISO 27001 = Certification standard (requirements for ISMS)
ISO 27002 = Best practice guide (implementation guidance for controls)
You get certified to ISO 27001. ISO 27002 helps you implement the controls.
Q: Is ISO 27001 required by law?
A: No, it's voluntary. However:
- •Some regulations reference it (NIS2 in EU)
- •Government contracts may require it
- •Industry standards may mandate it (finance, healthcare)
- •Practically required for EU B2B sales
Q: Can small companies get ISO 27001?
A: Yes! 35-40% of ISO 27001 certificates are for companies < 50 employees. With automation, it's accessible to startups.
Q: Do we need a dedicated ISMS team?
A: No. Small companies assign to:
- •CTO/CISO
- •Compliance manager
- •External consultant
- •AI platform (handles execution)
Q: Is ISO 27001:2013 still valid?
A: Technically valid until existing certificates expire, but:
- •New certs must use 2022 version
- •Transition period ended Oct 2025
- •Customers increasingly request 2022 version
- •Recommendation: Certify to 2022 version
Implementation Questions
Q: Can we use cloud services (AWS, GCP, Azure)?
A: Yes! Cloud makes ISO 27001 easier:
- •Cloud providers have ISO 27001 (inherit controls)
- •Better security than self-hosted typically
- •Built-in encryption, logging, monitoring
- •Easier to evidence
Document in SoA:
- •Physical controls: AWS responsibility (inherited)
- •Logical controls: Your responsibility
- •Shared responsibility model
Q: Do we need to implement all 114 controls?
A: No. Some controls may be "not applicable":
- •Physical data center controls (if using cloud)
- •Mainframe controls (if not using mainframes)
- •Paper records controls (if paperless)
Typical: 90-100 controls applicable (80-90%)
Q: Can we get ISO 27001 and SOC 2 simultaneously?
A: Yes! Benefits:
- •60-70% evidence reuse
- •Single gap remediation
- •Parallel audits possible
- •Timeline: 10-14 weeks (only 2-4 weeks more than single framework)
- •Cost: Only 30-40% more than single framework
Audit Questions
Q: Can the audit be done remotely?
A: Yes, especially post-COVID:
- •Stage 1: Always remote (documentation review)
- •Stage 2: Can be remote or on-site
- •Surveillance: Usually remote
- •Physical controls: May require site visit or photos
Q: How do we choose a certification body?
A: Look for:
- •UKAS, ANSI, or other accreditation
- •Experience in your industry
- •Pricing transparency
- •Timeline commitments
- •Positive references
Get quotes from 3 certification bodies.
Q: What happens if we fail?
A: You don't "fail." Instead:
- •Minor non-conformities: Fix within 90 days, cert still issued
- •Major non-conformities: Must fix and re-audit, cert delayed
- •With good preparation: 0-1 major, 3-8 minor (normal and acceptable)
Cost Questions
Q: Why is ISO 27001 audit more expensive than SOC 2?
A: Several factors:
- •2-stage audit (vs. single SOC 2 audit)
- •More comprehensive scope (ISMS vs. systems)
- •114 controls (vs. 90-120 SOC 2)
- •3-year validity (annualized cost lower)
Annualized comparison:
- •ISO 27001: $35K cert + $15K surveillance × 2 = $65K / 3 years = $22K/year
- •SOC 2: $25K × 3 years = $25K/year × 3 = $75K/3 years = $25K/year
Actually slightly cheaper annualized!
Q: Can we get certified for free or very cheap?
A: No legitimate ISO 27001 certification is free:
- •Minimum: $15K-$20K (small company, budget certification body)
- •Beware: "Free" certifications are not accredited/legitimate
- •Red flag: Certification < $10K (not credible)
