IT Audit Services That Test the Whole Population, Not a Sample

Sampling is the standard method because it was designed for paper. Our IT audit services test every record where the evidence already sits in a database, rather than twenty-five of them, which is the difference between finding the exceptions and finding some of them.

How an Audit Engagement Runs, and Where the Evidence Comes From

An audit is only as good as the population it reads. Most of the method is about getting a complete one before any testing starts.

We take a control, establish what it is supposed to prevent, extract the full set of records it applies to, and test every one of them. Exceptions are then validated with the people who own the process, because a technically failed control is sometimes a documented business decision and sometimes a real gap.

What comes out is a report with a finding, an owner, a cost of remediation and a date against each item. Findings without those four attributes get filed and not fixed, which is how organisations end up auditing the same weakness three years running.

A customer questionnaire nobody can answer confidently. An external auditor asking about access controls. A near miss that revealed a process working differently from its documentation. Aipxperts is engaged on all three, and the first question in every case is the same: which records would prove it either way.

If the question is defensive posture rather than control evidence, that is security work; if it is a decision rather than an assessment, it is IT consulting.

The Firm Whose Name Goes on the Report

An audit is worth what the organisation behind it is worth, because the findings get shown to customers and insurers. This is the scale of the business signing it.

Audit Types, Across the Life of a Control

Each of these it audit services is one sentence, because an audit scope should be readable in a minute. The detail belongs in the scoping document, not the sales page.

IT Process and Controls Audit

Our auditors test whether the controls described in your documentation are the controls actually operating in your systems.

Application and ERP Audit

Configuration, approval workflows and master data controls inside the system your operations run on, examined by our engineers record by record.

Segregation of Duties Audit

We build a conflict matrix across every role and every user to find who can both initiate and approve the same transaction.

Access and Identity Audit

Who has access to what, who granted it, who reviewed it, and how many accounts belong to people who have left, all counted by us rather than sampled.

IT Compliance Audit

Testing by our team against the specific obligation you are measured on, whichever standard or customer contract names it.

IT Security Controls Audit

Patching, logging, encryption and privileged access, assessed by our engineers as controls with evidence rather than as a tooling inventory.

Pre-Implementation Review

We check whether the controls in a system about to go live will produce the evidence you will later be asked for.

Post-Implementation Review

Whether a system that went live is operating the controls designed into it, which we usually test a year after anybody last looked.

Backup and Restore Audit

Our engineers check whether the restores have been tested, how recently, and whether the recorded result matches what was actually recovered.

Audits We Have Run, and What the Full Population Turned Up

The number worth looking for is how many exceptions were found against how many records tested. That ratio is the argument for commissioning it audit services at all.

We have contracted a developer from Aipxperts now for several months, based on a referral. We have been very pleased with the quality of the work, the knowledge and skill level of our developer, and the value we're receiving for our fee. We also very much appreciate that the development team works at night (effectively), so we are sometimes able to turn client requests around in a day.There have been a couple of situations where we needed urgent help outside of our developer's normal business hours, and we've received that help (for which I am very grateful). While we have some challenges with communication sometimes, our overall satisfaction level is very high.

The Obligation Your Sector Is Actually Tested On

Sector determines which control gets examined hardest and by whom, which is what shapes it audit services more than the tooling does. That is the part worth agreeing before the scope is written.

Fintech and financial services

Transaction authorisation and the ability to demonstrate that no single person could complete a payment alone. Segregation of duties is the finding that carries the most weight here, and it is the first matrix we build. More on fintech and financial services.

Healthcare administration

Access to records, and evidence that the access was appropriate rather than merely granted. Our engineers test the access log rather than the user list, because the log is the population that matters. More on healthcare administration.

Retail

Point of sale, refunds and price overrides, where the control question is who can authorise an exception at a till without a second person involved. We test every override rather than a day’s worth. More on retail.

Automotive and dealer networks

Warranty claims and dealer settlement, where an approval granted inside a partner organisation still has to be evidenced inside yours. Cross-boundary authorisation is the finding nobody expects, and our testing goes looking for it. More on automotive and dealer networks.

Logistics and warehousing

Inventory adjustments and proof of delivery records, where the exception that matters is a write-off nobody countersigned. Our team counts those against the full adjustment population. More on logistics and warehousing.

Energy and utilities

Operational technology adjacent to office systems, where the significant finding is usually a connection between the two that nobody designed. We map that boundary before testing anything else. More on energy and utilities.

eCommerce

Discount codes, refunds and manual order edits, where the exception that matters is a transaction adjusted by somebody with no approval attached. Every adjustment gets tested by us, not a sample of them. More on eCommerce.

Aipxperts Commits to This Before an Audit Starts

Commitments Aipxperts makes on audit work, plus the limitation that decides whether we are the right firm for you at all.

01Complete populations rather than a sampleWhere the evidence is in a system, every record is tested. Sampling remains appropriate for paper-based evidence and we will say when we are using it, but it is never the default.

02Engineers run the testingThe people extracting and analysing the data are engineers rather than auditors following a script. It changes what gets noticed, particularly around how a system was configured rather than how it was documented.

03Every finding is priced, owned and datedA finding with no cost estimate, no named owner and no target date is an observation. Reports full of observations are why the same weaknesses appear in consecutive audits.

04Independence here is structuralWe do not implement the systems we audit for the same client, and we will withdraw from an audit rather than review our own work. That is a constraint on our revenue, which is what makes it worth stating.

05What this team cannot issueAipxperts is not a certification body. We cannot issue a SOC 2 report or an ISO 27001 certificate, and no work here should be represented as either. What we can do is test your controls against the obligation and tell you what a certifying auditor would find, before they find it.

Why Sampling Misses the Rare Event

This is a methodology argument rather than a quality claim, which means you can test it on any firm you are considering with a single question: how many items do you test.

How the Testing Is Actually Run

The analysis, extraction and reporting tooling our engineers use on audit work. Everything is read-only against your systems, and where your environment already provides an extract mechanism we use yours rather than introducing ours.

Cloud services

Configuration, IAM policy and audit-trail review across the major providers, including tenant settings rarely revisited after the migration closed.

Evidence Handling and Independent Opinion on This Work

An audit reads more of your data than almost any other engagement and changes none of it. Both halves of that sentence need controls behind them: the NDA is signed before any access is granted, and the scope document names the systems that access covers.

What the audit reads, and what it never changesRead-only access throughout, with any request for write access treated as a scoping error rather than a convenience. Nothing in your systems is modified by the testing.Access, time-boxed and revoked on issueNamed individuals, scoped to the systems in the agreed scope, time-boxed to the engagement and revoked on the day the report is issued. The access register is part of the deliverable.Where the report can and cannot goThe report is yours. Share it with your regulator, your external auditor, your board or a customer as you choose. We do not publish findings, name clients in marketing without written consent, or retain the extracted populations after the engagement closes unless you ask us to.On certification and independent opinionAipxperts holds neither ISO 27001 nor SOC 2, and does not present itself as a certification body. The independent evidence available is the client review record alongside the report itself, which is written to be read by somebody who did not commission it.

Running an Audit, and What Your Team Has to Provide

Evidence provisioning is the real schedule risk on an audit and almost nobody states it upfront. It is named at every stage.

01Scope and obligation agreementWhich systems, which controls, and which obligation the testing is measured against, agreed with our team before anything is extracted. You supply the obligation itself, whether that is a regulation, a customer contract or an internal policy.02System and population inventoryWhat systems hold the relevant records, and what a complete set of those records looks like. We need somebody who knows where the data actually lives, for about half a day.03Read-only access provisioningAccounts created, scoped and tested before our extraction begins. You supply the access, and this is the stage that most often delays an audit.04Population extraction and validationRecords extracted and reconciled against a control total, because an incomplete population invalidates everything after it. You supply a control total we can reconcile against, from a source other than the extract.05Control testing across the full populationEvery record tested against the control by our engineers, with exceptions isolated and counted rather than estimated. Nothing is needed from you here; this stage runs on our side.06Exception validation with your ownersEach exception put to the person who owns the process, because some are gaps and some are documented decisions. We need an hour each from the process owners, and their genuine answers rather than defended ones.07Report, remediation ownership and a retest dateFindings with cost, owner and date, and a retest we book before the engagement closes. You supply the names: a finding without an owner will not be fixed, and we would rather leave it blank than pretend.

What Comes Up on an Audit Scoping Call

Scope, cost, evidence and access on it audit services, including when commissioning one is the wrong move.

My idea is confidential – happy to sign an NDA.

Systems in scope first, then controls per system, then how hard the data is to extract. A modern system with a reporting interface is contained work. A system where the population has to be reconstructed from several sources is not, and that is usually apparent within an hour of scoping.

Scoping and extraction dominate the timeline. Testing itself is fast once the population is clean. The variable that moves the date is almost always how quickly read-only access is provisioned on your side.

No. Aipxperts is not a certification body and nothing here should be represented as certification. What we do is test your controls before the certifying auditor does, so what they find is not a surprise.

Where the evidence sits in a system, yes. Where it is paper or requires physical observation, sampling still applies and we say which parts of the scope fall into each category. The commitment is to be explicit rather than to be exhaustive about things that cannot be.

Concentrated at the start and at exception validation. Expect somebody who knows the data for roughly half a day, whatever your access provisioning takes, and an hour each from process owners later. Very little in between.

Not on the same systems in the same period. Auditing our own remediation would make the audit worthless. We will tell you what fixing each finding involves and roughly what it costs, and you can use your own team or another supplier.

Each finding with the control it relates to, the exceptions found against the population tested, the business consequence, a named owner, an estimated remediation cost and a target date. Written to be read by somebody who did not commission it.

Yes. It is your report and it is written expecting that audience. We do not attach conditions to its circulation.

Yes, and the retest date is set when the report is issued rather than negotiated later. Findings without a booked retest have a way of remaining findings.

When you already know the answer and have not acted on it. An audit that confirms a known gap gives you evidence, not information, and if the budget is limited it is better spent on the fix. We will say so on the call rather than after the invoice.

Where an Audit Finding Goes Next

An audit produces work. These are the engagements that most often absorb it, run by a different team from the one that audited.
