The Three Reasons Companies Come to Us for ISO 27001

Specific, urgent, business-critical situations where ISO 27001 is the only path forward.

European Enterprise Deals Require It

Your prospect in Europe, the Middle East, or Asia-Pacific will not sign without ISO 27001 certification. Their procurement team has made it a non-negotiable requirement. The deal is stalled and every week it sits there, the risk of losing it grows.

Entering Regulated or Government Markets

You are expanding into markets where ISO 27001 is a baseline requirement - financial services, healthcare, government contracts, or critical infrastructure under NIS 2. No certificate, no contract.

Customers Demand International Credibility

Your global customers need proof that you manage information security systematically. SOC 2 alone is not enough for international markets. ISO 27001 is the globally recognized standard that opens doors SOC 2 cannot.

ISO 27001 framework overview showing Annex A controls and ISMS requirements

What Is ISO 27001?

ISO 27001 is the international standard for information security management systems (ISMS), published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It provides a systematic framework for managing sensitive company and customer information through risk assessment, control implementation, and continuous improvement.

Unlike SOC 2, which produces an attestation report, ISO 27001 results in a formal certification - you either pass or you do not. A certified organization has demonstrated to an accredited, independent auditor that it has implemented and maintains a comprehensive set of information security controls. The certificate is valid for 3 years, with annual surveillance audits to verify ongoing compliance.

The 2022 revision (ISO 27001:2022) restructured the Annex A controls from 14 domains with 114 controls into 4 streamlined categories with 93 controls. It introduced 11 new controls covering modern security challenges: threat intelligence, information security for cloud services, ICT readiness for business continuity, physical security monitoring, configuration management, information deletion, data masking, data leakage prevention, monitoring activities, web filtering, and secure coding.

ISO 27001 is not a checklist exercise - it requires a functioning management system. Many companies fail because they create documentation that does not reflect actual operations. Our approach builds an ISMS around how your organization actually works, not a set of templates that sit on a shelf.

The Four Annex A Control Categories

ISO 27001:2022 organizes 93 controls into four categories. All applicable controls must be addressed in your Statement of Applicability - the central document auditors review.

Organizational Controls (A.5)

37 Controls

Policies, roles, responsibilities, threat intelligence, asset management, access control, supplier relationships, information security in project management, and incident management. This is the largest category and covers how your organization governs information security at the management level.

People Controls (A.6)

8 Controls

Screening, terms and conditions of employment, information security awareness and training, disciplinary process, responsibilities after termination, confidentiality agreements, and remote working security. These controls ensure your people are your strongest link, not your weakest.

Physical Controls (A.7)

14 Controls

Physical security perimeters, entry controls, securing offices and facilities, physical security monitoring, protection against environmental threats, working in secure areas, clear desk and screen policies, equipment siting and protection, and secure disposal of storage media.

Technological Controls (A.8)

34 Controls

User endpoint devices, privileged access, information access restriction, secure authentication, capacity management, malware protection, vulnerability management, configuration management, data masking, data leakage prevention, monitoring, web filtering, secure coding, and network security.

Not every control applies to every organization. We help you determine applicability during the gap assessment and document justifications for any exclusions in your Statement of Applicability.

ISO 27001 vs SOC 2 comparison for companies pursuing international security certification

ISO 27001 vs SOC 2 - Which Do You Need?

Many companies need both. If you already have SOC 2, ISO 27001 builds on 70-80% of the same controls. We help you decide during the free strategy call.

ISO 27001 Readiness FAQ

How long does ISO 27001 certification take?

Typical certification takes 6-12 months from initial gap assessment to Stage 2 audit completion. Organizations with existing security frameworks (SOC 2, NIST) can often accelerate to 4-6 months by leveraging overlapping controls. The timeline depends on your starting maturity, scope complexity, and internal resource availability.

How much does ISO 27001 certification cost?

Total cost varies by organization size and complexity. Readiness consulting typically ranges from $20,000-$80,000, certification body audit fees range from $10,000-$30,000, and tooling/platform costs range from $5,000-$20,000 annually. We provide fixed-price proposals after a free scoping call.

What is the difference between ISO 27001 and SOC 2?

ISO 27001 is an international certification standard requiring an Information Security Management System (ISMS) with 93 controls. SOC 2 is a US-based attestation report evaluating controls against Trust Service Criteria. ISO 27001 is recognized globally and is prescriptive about management system requirements. SOC 2 is more common in the US SaaS market. Many organizations pursue both.

Do we need ISO 27001 if we already have SOC 2?

It depends on your market. If you sell to European, Middle Eastern, or Asia-Pacific customers, ISO 27001 is often expected or required. The good news is that roughly 70% of controls overlap with SOC 2, so the incremental effort is significantly less than starting from scratch.

What are the mandatory documents for ISO 27001?

The standard requires: ISMS scope document, information security policy, risk assessment methodology, risk assessment results, risk treatment plan, Statement of Applicability, information security objectives, evidence of competence, operational planning documents, results of internal audits, and results of management reviews. In practice, auditors expect about 15-20 core documents.

What is the Statement of Applicability?

The Statement of Applicability (SoA) is a mandatory document that lists all 93 Annex A controls, states whether each is applicable or not applicable to your organization, provides justification for exclusions, and references the implementation status. It is one of the first documents auditors review.

Can small companies get ISO 27001 certified?

Yes. ISO 27001 is designed to be scalable. A 20-person company can achieve certification with a proportionally smaller ISMS. The key is scoping appropriately — you certify the parts of your organization that handle information security, not necessarily everything. We have certified companies as small as 15 employees.

What happens after certification?

ISO 27001 certificates are valid for 3 years. During that period, you undergo annual surveillance audits (shorter than the initial audit) to verify continued compliance. At the end of 3 years, a full recertification audit is required. We provide ongoing support for surveillance audit preparation.
