Top 10 Questions to Ask Before Hiring an ISO 27001 Consultant

Hiring an ISO 27001 consultant is a critical step for any organisation aiming to achieve ISO 27001 certification, improve information security, and demonstrate compliance. The right consultant can guide you through risk assessment, documentation, implementation, internal audits, and liaise with certification bodies. However, not all consultants are equal. To ensure you're making a wise investment, here are the top 10 questions you should ask before hiring an ISO 27001 consultant.


1. What Is Your Experience with ISO 27001:2022?

ISO 27001 was updated in 2022 to include a revised Annex A aligned with the latest risk landscape. Ask whether the consultant is well-versed in the current version. Look for experience with the new control structure, as well as recent projects where the 2022 version was implemented.

Why it matters: You need a consultant familiar with the latest standard to avoid gaps in compliance.

2. Do You Have Industry-Specific Experience?

Information security risks vary by sector—what applies in healthcare might differ in finance or tech. Ensure your consultant has experience in your industry, understands its specific threats, and knows regulatory overlaps (e.g., APRA CPS 234, GDPR, HIPAA).

Why it matters: A tailored approach ensures faster compliance and stronger security alignment.

3. Can You Support Both Implementation and Certification Readiness?

Some consultants specialise only in documentation or audits. Ideally, your ISO 27001 consultant should assist throughout the entire journey—from initial gap analysis and ISMS development to internal audits and external audit support.

Why it matters: End-to-end support saves time, ensures continuity, and avoids fragmented efforts.

4. How Do You Approach Risk Assessment and Risk Treatment?

The heart of ISO 27001 lies in effective risk management. Ask how they conduct risk assessments and design treatment plans. Do they use qualitative, quantitative, or hybrid methods? Are the results tailored to your organisation’s size and complexity?

Why it matters: Effective risk assessment ensures relevant controls are chosen and implemented appropriately.

5. What Tools or Frameworks Do You Use?

Does the consultant use any ISO 27001 compliance software or risk management platforms? Are they aligned with NIST CSF, COBIT, or other relevant frameworks if needed? The right tools can streamline your journey and improve control monitoring.

Why it matters: Efficiency and integration with your existing systems can save resources and improve results.

6. Can You Provide Case Studies or References?

Ask for examples of similar organisations they’ve helped achieve ISO 27001 certification. Testimonials, metrics, or client success stories help validate their claims and approach.

Why it matters: Proven success reduces your risk of choosing an inexperienced or ineffective consultant.

7. What Is Your Approach to Training and Awareness?

ISO 27001 requires ongoing staff awareness and training. A good consultant will support you in building a security culture through workshops, LMS integration, or awareness sessions.

Why it matters: Certification isn’t just about documents—it’s about embedding security across your team.

8. How Do You Ensure Ongoing Compliance After Certification?

ISO 27001 certification isn’t a one-time task. Maintenance, surveillance audits, and continuous improvement are critical. Ask whether the consultant offers post-certification support or ongoing managed services.

Why it matters: Staying compliant means staying proactive, not reactive.

9. Are You Independent or Tied to a Specific Certification Body?

While consultants can work closely with certification bodies, they must remain independent. Avoid consultants that pressure you to certify with one body over another without clear justification.

Why it matters: Independence ensures unbiased advice and better alignment with your goals.

10. What Are Your Fees and Engagement Structure?

Transparency is key. Understand how the consultant charges—fixed fee, hourly, or milestone-based. Clarify deliverables, timelines, and whether follow-up support is included.

Why it matters: Avoiding hidden costs and misaligned expectations leads to a smoother engagement.
