ISO/IEC 27001 Information Security Consulting

ISO/IEC 27001 sets requirements for an Information Security Management System, or ISMS. It helps organisations manage information-security risks through defined governance, risk assessment, proportionate controls, performance review and continual improvement.

Certivanta helps organisations build an ISMS that reflects their operations, technology, contractual commitments and risk profile. We prepare your management system for an independent certification audit; the certification body remains responsible for the audit and certification decision.

ISO 27001 is particularly relevant to software providers, cloud services, fintech businesses, financial institutions, professional services and organisations that process sensitive customer or supplier information. It can support security due diligence, enterprise procurement and customer-assurance requirements.

• ISMS scope, context and information-security governance
• Asset, threat, vulnerability and information-security risk assessment
• Risk treatment and the Statement of Applicability
• Security policies, responsibilities and operational controls
• Internal audits, management review, corrective action and certification readiness

A well-run ISMS can improve accountability for information security, create a consistent approach to risk and provide clearer evidence for customers and other stakeholders. It also helps leadership monitor whether security controls remain appropriate and effective.

Organisations can coordinate ISO 27001 with ISO 22301 business continuity, ISO 20000-1 IT service management and ISO 42001 AI governance to strengthen security, resilience and technology oversight.

No. Any organisation that depends on information can use ISO 27001. The scope and controls should be proportionate to the organisation’s information, services, risks and obligations.

No management system can guarantee that incidents will never happen. ISO 27001 provides a structured approach to identifying, treating, monitoring and improving the management of information-security risk.

No. Certivanta supports ISMS implementation and certification readiness. An independent certification body conducts the certification audit and makes the certification decision.

A South African software or fintech provider may receive security questionnaires from enterprise customers while relying on cloud platforms, remote staff and specialist suppliers. An ISMS can bring those obligations into one risk-based system: define the service scope, identify information and dependencies, assess threats and vulnerabilities, approve treatment decisions and retain evidence that controls operate. ISO 27001 can support assurance and privacy governance, but certification does not by itself prove compliance with POPIA or any contract.

Cost drivers include ISMS scope, cloud and on-premise architecture, supplier reliance, the number of locations, existing security evidence and the maturity of risk, incident and access-management processes. Technical remediation, penetration testing, security tools, legal advice, the ISO standard and certification-body fees are excluded unless agreed in writing. A focused scope and reliable asset, risk and supplier information reduce avoidable effort. See the consultation package and define the boundary before comparing proposals.

• Which services, information, teams and technologies must the ISMS cover?
• What security or privacy commitments have customers already imposed?
• Who can approve risk acceptance and treatment resources?
• Which controls need technical specialists outside the consulting engagement?
• What operating evidence must exist before the independent audit?
