Independent Audit

ISO 27017 and ISO 27018 Internal Audit Services

An independent internal audit of the ISO 27017 and ISO 27018 controls in your ISO 27001 ISMS that meets ISO 27001 Clause 9.2, done by auditors from outside your team. Most audits take two to four weeks and end in a formal report with every finding rated.

  • A Clause 9.2 report with every finding rated major, minor or observation
  • Cloud security and cloud PII controls tested against your Statement of Applicability
  • Led by a senior CISSP in the US or Canada

For most SMBs, a standalone ISO 27017 and ISO 27018 internal audit costs USD $5,000 to $15,000.

What does an ISO 27017 and ISO 27018 internal audit cover?

A risk-based audit of your cloud controls against ISO/IEC 27017:2026, ISO/IEC 27018:2025 and ISO 27001, from planning to the final report.

Frame (8)

Assess: Audit Planning

  • What We Do

    We review your ISMS scope, the cloud services in scope, your Statement of Applicability, the split of duties with customers and prior audit findings. We build an audit plan weighted by risk and schedule interviews with process owners.

  • What You Get

  • Audit Plan:
    Scope, criteria and method, weighted by the cloud services and customer data that carry the most risk.

  • Interview Roster:
    The process owners we interview, with topics and the evidence we ask each one to show.

Frame (9)

Assess: Document Review

  • What We Do

    We review policies, procedures, the risk assessment, customer agreements and sub-processor disclosures against ISO 27001 Clauses 4 to 10 and the ISO 27017 and ISO 27018 controls you include.

  • What You Get

  • Document Review Findings:
    Each document checked for coverage, currency and approval, and for whether it matches how your team works.

Frame (10)

Assess: Cloud Control Testing

  • What We Do

    We test the ISO/IEC 27017:2026 and ISO/IEC 27018:2025 controls in your Statement of Applicability. We sample evidence such as administrator access logs, customer data deletion records, sub-processor notices and PII disclosure request records.

  • What You Get

  • Control Testing Workpapers:
    For each control, the test performed, the evidence reviewed and the conclusion.

Frame (11)

Assess: Interviews and Process Verification

  • What We Do

    We interview engineering, operations and support staff to confirm they know their responsibilities for customer data and can show them, from access to deletion.

  • What You Get

  • Interview Notes:
    What was asked, what was shown, and where practice differs from the documented procedure.

Frame (12)

Report: Audit Report and Nonconformity Register

  • What We Do

    We write a formal internal audit report that meets ISO 27001 Clause 9.2, with nonconformities, observations and recommended corrective actions ordered by certification risk.

  • What You Get

  • Internal Audit Report:
    Every finding classified, tied to a clause or control, and backed by evidence.

  • Nonconformity Register:
    Major and minor nonconformities with clause references, evidence and a recommended corrective action.

Frame (13)

Report: Findings Walkthrough and Management Review Input

  • What We Do

    We walk your team through every finding, help you order the fixes, and format the results for your Clause 9.3 management review. Follow-up verification of corrective actions is optional.

  • What You Get

  • Remediation Plan:
    Fixes ordered by certification risk, each with an owner and a target date.

  • Management Review Input:
    Audit results, risk changes and recommended actions for leadership sign-off.

What do you get from an ISO 27017 and ISO 27018 internal audit?

Four things you hold at the end, ready for the certification auditor.

A Clause 9.2 audit report

A formal report your certification body can review, with scope, criteria, method and every finding tied to a clause or control.

A rated nonconformity register

Every finding rated major, minor or observation, with the evidence behind it and a recommended corrective action.

A dated remediation plan

Fixes ordered by certification risk, each with an owner and a target date, timed to close before the certification audit.

Management review input

Results formatted for your Clause 9.3 management review, so leadership signs off on what was found and what changes.

When is an outside ISO 27017 and ISO 27018 auditor the right call?

For many cloud providers, the trigger is a certification audit on the calendar and no one on staff who can audit the cloud controls without auditing their own work.

Right call when

  • No one on staff is both trained in ISO auditing and independent of the cloud controls

  • Your certification audit is booked and the internal audit is still open

  • The engineers who built the controls are the engineers who operate them

  • You want ISO 27001, ISO 27017 and ISO 27018 audited together in one engagement

Wrong call when

  • You need the lowest possible price. Our pricing is competitive, but every audit is run by experienced auditors, goes through several rounds of QA and ends in a detailed report, so we are rarely the cheapest option

What do cloud providers ask about ISO 27017 and ISO 27018 internal audits?

For most SMBs, a standalone ISO 27017 and ISO 27018 internal audit costs USD $5,000 to $15,000. The price depends on the cloud services in scope, whether you include ISO 27017, ISO 27018 or both, and the number of controls in your Statement of Applicability. Auditing the full ISO 27001 ISMS in the same engagement raises the scope. No prior Truvo engagement is required.

ISO 27017 and ISO 27018 are control sets that extend an ISO 27001 ISMS. ISO 27001 Clause 9.2 requires internal audits at planned intervals, and certification bodies typically expect the audit to cover every control in your Statement of Applicability, including the ISO 27017 and ISO 27018 controls.

Clause 9.2 requires audits at planned intervals. Many organizations audit once a year, and a risk-based plan can add audits after significant changes, such as a new cloud service, a new hosting region or a new sub-processor.

Anyone competent and impartial. ISO 27001 Clause 9.2 asks you to select auditors so the audit stays objective and impartial, so the engineer who designed or operates a cloud control should audit a different area. Many small and mid-sized companies have no one who meets both tests, which is why they bring in an outside auditor.

Yes. The three standards share one ISMS and one Statement of Applicability, so we audit them in one engagement, with one plan, one evidence request and one report that references the clauses and controls of each standard.

You commission the internal audit to find problems early. An accredited certification body performs the certification audit and decides on certification. The certification auditor reviews your internal audit report as evidence that Clause 9.2 is working.

Two to four weeks for most small and mid-sized organizations, from planning to final report. Finish the audit six to eight weeks before the certification audit, so there is time to fix findings and show the fixes work.

Yes, as a separate engagement with a different team, so the auditor stays independent of the program. See our ISO 27017 and ISO 27018 certification consulting page.

Client data, documentation and sensitive materials are stored in secure North American cloud environments. Every engagement is led by a senior CISSP in the US or Canada with 10+ years in security, and every consultant on the engagement is an experienced, vetted professional.

How is a Truvo ISO 27017 and ISO 27018 internal audit different?

Our auditors build and operate management systems, so findings come with fixes your team can carry out.

The Internal DIY Approach

  • Document-Only Audits:
    Many internal audits confirm that cloud security policies exist. The certification auditor tests whether your team follows them.

  • Independence Gap:
    An engineer who built the cloud controls is often the only person who knows them, and Clause 9.2 asks for an impartial auditor.

  • Generic Findings:
    "Consider improving documentation" gives your team no clear fix before Stage 2.

The Truvo Approach

  • Practitioner-Led Audit:
    Our auditors build and operate management systems, and every engagement is led by a senior CISSP in the US or Canada.

  • Cloud Control Testing:
    We test the ISO 27017 and ISO 27018 controls in your Statement of Applicability, and record the evidence and conclusion for each.

  • Certification-Focused Findings:
    Every finding is rated major, minor or observation, with a clause reference and a recommended fix ordered by certification risk.
