Internal Audit Services & ISO Auditor Training

Expert-led internal audits, auditor training, and gap analysis services to strengthen your management system and prepare for certification.

Internal Audit Services

Internal Audit Services

ISO standards require that internal audits are conducted by auditors who are independent from the processes being audited — you shouldn't audit your own work. Kaizen provides outsourced internal audit services that give your organization the independence and expertise needed to meet this requirement while delivering genuinely useful findings. We audit against ISO 9001, ISO 14001, ISO 45001, ISO 27001, and integrated management systems.
  • Fully independent audits meeting ISO impartiality requirements
  • Standards covered: ISO 9001, ISO 14001, ISO 45001, ISO 27001, and integrated management systems
  • Structured process: scope agreement → on-site or remote audit → findings report with Nonconformities, Observations, and Opportunities for Improvement
  • Corrective action follow-up to ensure findings are properly closed
  • Powered by the Kaizen Audit tool — a custom-built platform for audits and gap analyses that delivers clearer, more actionable outputs
  • Experienced auditors who understand the standards AND your industry — not just checkbox auditors

Internal Auditor Training

Internal Auditor Training

Build in-house audit competency so your team can conduct effective internal audits year-round. Kaizen's internal auditor training is designed for your staff — not to be confused with lead auditor training (PECB, Exemplar Global, IRCA pathways), which trains certification body auditors. Internal auditor training focuses on the practical skills your team needs to audit your own management system.
  • How to plan and prepare for internal audits
  • Conducting effective audit interviews and gathering objective evidence
  • Writing clear, actionable audit findings
  • Following up on corrective actions and verifying effectiveness
  • Standards-specific training available: ISO 9001, ISO 14001, ISO 45001, ISO 27001
  • Delivered on-site at your facility or remotely — flexible scheduling

Gap Analysis Services

Gap Analysis Services

A gap analysis is often the first step on the path to certification — it answers the question: where are we today vs. where do we need to be? Kaizen offers both self-service and consultant-led options.
  • Self-service: Use our free interactive gap analysis tools to get an instant high-level compliance snapshot
  • Consultant-led: Kaizen performs an in-depth evaluation of your processes, identifies specific gaps, and creates a detailed action plan
  • Covers all major ISO standards and integrated management systems
  • Clear deliverables: prioritized gap report with recommended corrective actions and implementation timeline

We very much recommend Trenton's consultation expertise in compliance! Trenton helped us, not only completely build out our company Quality Management System, but also understand the practices for ISO 9001 compliance standard. We decided to pursue CMMI SVC Level 3, as well as ISO 27001 concurrently with ISO 9001. Trenton was our lead consultant for ISO 9001; however, he stepped in and helped us.
