ISO 27001 lead auditors and ISMS implementation consultants

Digiventi provides hands-on ISMS implementation consultants to establish an information security management system aligned with ISO/IEC 27001:2022. They assess existing practices against clauses 4–10 and define a workable implementation backlog.

Work covers scope boundaries and organizational context, followed by security policies and assigned responsibilities. Consultants establish document control and evidence requirements with the people responsible for operating each process. For an existing ISMS, a gap assessment identifies missing requirements and changes needed before an audit.

ISMS consultants connect documented risks to control decisions that business owners can approve and engineers can implement.

• Risk assessment and treatment: Define assessment criteria, evaluate information security risks, assign risk owners and record treatment decisions with acceptance criteria.
• Statement of Applicability: Document necessary controls and justify Annex A inclusions or exclusions. Work with control owners on implementation evidence, including access reviews and supplier security checks.

The resulting records link identified risks to control ownership and evidence of implementation.

ISO 27001 lead auditors plan and conduct internal audits using ISO 19011 guidance. They sample evidence and interview process owners to assess conformity with the ISMS requirements, documenting nonconformities against specific criteria.

Readiness reviews test whether documented processes match actual practice before Stage 1 or Stage 2 certification audits. Audit assignments must preserve objectivity and impartiality, including independence from activities reviewed. Certification decisions remain with the certification body; Digiventi specialists support preparation and internal assurance.

ISMS consultants support ongoing responsibilities after implementation, including risk reassessments and updates when systems or suppliers change. They help process owners maintain evidence and prepare management review inputs grounded in control performance.

For audit findings, specialists investigate root causes and define corrective actions with accountable owners. Follow-up checks assess whether those actions addressed the cause before closure. Support can also cover surveillance audit preparation and the resolution of overdue findings within an existing ISMS.
