IT Audit & Control Assurance
Service overview
Your enterprise clients, auditors, and regulators expect IT controls that operate as documented — not just policies that exist on paper. Sitoo Advisory delivers independent IT audit and control assurance reviews with the depth and rigor of a Big 4 engagement, scoped to your environment and priced for a company your size.
Independent Assurance Your Stakeholders Will Accept.
Self-attestation does not satisfy enterprise customers, auditors, or insurers any more. Sitoo Advisory delivers independent, evidence-based IT control reviews — access management, change management, backup and recovery, system operations — with the testing rigor of a Big 4 engagement and a fraction of the timeline.
The Evidence Gap Between “Policy Exists” and “Control Operates.”
Most SMB IT environments have policies but cannot prove the underlying controls actually operate. Sitoo Advisory tests the controls, organizes the evidence, and produces the workpapers and audit narrative your external auditor will accept — closing the gap that historically generates findings.
Is This Right for Your Business?
What We Fix
No documented IT general controls
Access is granted and removed informally. Change control is manual and undocumented. Backup verification has never been tested. Your auditor is about to find all of this.
Audit findings you can’t close
Your prior audit produced IT findings. You don’t have the expertise to assess whether remediation was sufficient or to produce evidence that controls now operate as designed.
No separation of duties
In small IT environments, the same person who makes changes often approves them and reviews the logs. This is a known audit finding and a regulatory concern.
Evidence disorganization
When auditors request 12 months of access reviews, change tickets, and backup logs, you spend two weeks searching email threads for evidence that may not exist in a usable format.
Deliverables & Scope
Every engagement produces defined, tangible deliverables. No open-ended hours.
IT General Controls (ITGC) Review
Structured assessment of access management, change management, backup and recovery, and system availability controls.
Access Management Audit
User provisioning, de-provisioning, privileged access, and separation of duties review with exception reporting.
Change Management Audit
Evaluation of change control procedures, approval workflows, testing requirements, and emergency change documentation.
Audit Evidence Package
Organized evidence artifacts by control domain, formatted for external auditor submission or regulatory review.
Management Response & Remediation Plan
Documented management responses to findings with assigned owners and target remediation dates.
How the Engagement Works
Scope Definition & Evidence Request
We define the audit scope, issue an evidence request list, and conduct opening interviews. Typically completed within the first week.
Fieldwork & Control Testing
Evidence is reviewed, controls are tested, and exceptions documented. We work efficiently to minimize operational disruption.
Findings, Responses & Evidence Delivery
Draft findings reviewed with management, responses documented, and the complete evidence package organized for auditor or regulatory submission.
What You Will Have at Engagement End.
Independent ITGC opinion
A documented, evidence-backed determination of where your IT general controls operate effectively and where they don’t — the same artifact your external auditor would produce.
Organized audit evidence package
Workpaper-quality evidence library by control domain, formatted for external auditor handoff — shortening your next audit fieldwork.
Documented management responses
Owner-assigned, dated remediation plan for every finding — the disclosure auditors and boards expect to see alongside the findings.
Pre-audit readiness signal
Surface the findings your external auditor would otherwise raise — before they're in your audit report and before they require remediation under time pressure.
