ISO/IEC 27001
The global gold standard for information security management
§ Overview
ISO 27001 is an international standard for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS). It provides a systematic approach to managing sensitive company information, ensuring it remains secure through people, processes, and technology controls. Certification is recognized worldwide and demonstrates to clients, partners, and regulators that your organization takes information security seriously.
§ Who needs this
Any organization that handles sensitive data — especially SaaS companies, cloud providers, fintech, healthcare tech, and companies selling to enterprise clients. Increasingly required in vendor assessments and RFPs. If your customers ask 'Are you ISO 27001 certified?' — you need this.
§ Key requirements
Information Security Management System (ISMS)
Establish a formal ISMS that covers your entire organization's approach to information security, including scope definition, risk assessment methodology, and management commitment.
Risk Assessment & Treatment
Conduct a comprehensive risk assessment identifying threats, vulnerabilities, and impacts. Create a risk treatment plan addressing each identified risk with appropriate controls.
Annex A Controls (93 controls)
Implement applicable controls from the 93 controls in Annex A, covering areas like access control, cryptography, physical security, operations security, and supplier relationships.
Documentation & Policies
Maintain a complete set of security policies, procedures, and records. This includes mandatory documents like the Statement of Applicability (SoA), risk assessment reports, and internal audit results.
Internal Audit Program
Conduct regular internal audits to verify ISMS effectiveness. Internal auditors must be independent from the areas they audit.
Management Review
Senior management must review the ISMS at planned intervals to ensure its continuing suitability, adequacy, and effectiveness.
Continual Improvement
Demonstrate ongoing improvement of the ISMS through corrective actions, preventive measures, and regular updates to policies and controls.
§ Steps to compliance
Gap Analysis
Assess your current security posture against ISO 27001 requirements. Identify what you already have and what's missing. This typically takes 2-4 weeks.
Define ISMS Scope
Determine which parts of your organization, processes, and systems will be covered by the ISMS. Start focused — you can expand later.
Risk Assessment
Identify information assets, threats, and vulnerabilities. Assess likelihood and impact. Prioritize risks and define treatment plans.
Implement Controls & Policies
Deploy the technical and organizational controls needed to address identified risks. Write and approve all required security policies.
Training & Awareness
Train all employees on the ISMS, their security responsibilities, and relevant policies. Security awareness is a key audit requirement.
Internal Audit
Conduct a full internal audit of your ISMS. Document findings and create corrective action plans for any non-conformities.
Management Review
Present ISMS performance, audit results, and improvement plans to senior management for review and approval.
Certification Audit (Stage 1 & 2)
Stage 1: Auditor reviews documentation. Stage 2: On-site audit verifying implementation. If successful, you receive certification valid for 3 years with annual surveillance audits.
