IT Audits and ISAE Reports

Not all IT assurance reports serve the same purpose. The right choice depends on the services you provide, the data you handle, and what your customers need to know.

ISAE 3000 and ISAE 3402 are two different assurance standards. ISAE 3000 can be used to assess a wide range of areas, including GDPR, cybersecurity, and selected NIS2 requirements. These aren’t separate standards. They’re different ways of applying ISAE 3000, each with a specific focus.

The main difference between ISAE 3000 and ISAE 3402 is what they cover. ISAE 3000 can be used for assurance engagements across a range of subject matters, while ISAE 3402 focuses specifically on controls at service organizations that are relevant to their customers’ internal control over financial reporting.

Here are some of the most common options:

The scope of an ISAE 3000 report depends on the requirements and criteria you need to address. In some cases, more than one type of report may be necessary.

If you provide IT operations, outsourcing, or other services that support your customers’ financial processes, an ISAE 3402 report may be the right choice.

It gives customers a clearer picture of the controls you have in place and how those controls operate. These might include managing system access, making changes to IT environments, overseeing daily operations, or handling security incidents, as long as the controls are relevant to your customers’ financial reporting.

An ISAE 3402 report also helps your customers and their auditors obtain the evidence they need for the systems and processes you manage on their behalf.

A Type I report looks at whether your controls are properly documented and designed at a specific point in time. Think of it as a snapshot of your control environment that you can also share with customers.

A Type II report takes things a step further. The auditor also tests whether those controls have actually worked over an agreed period.

If you’re new to IT assurance reports, starting with Type I and moving to Type II later can be a practical approach. It gives you a chance to review your existing controls, identify areas for improvement, and make any necessary changes before demonstrating how the controls perform over time.

Of course, your customers’ requirements matter. Some may expect a Type II report from the start.

Start by understanding why you need an assurance report and what your customers expect.

You don’t need to have every policy, procedure, and control in place before talking to an IT auditor. Many organizations already have good security practices but haven’t documented or organized them in a way that supports an audit.

We help you identify what’s already in place, where there may be gaps, and what you need to do to prepare.

Here’s what a typical process looks like:

1. 01

   Scoping

   Needs and report type

2. 02

   Preparation

   Control description

3. 03

   IT Audit

   Review and testing

4. 04

   Assurance Report

   Completion and reporting

Once you’ve completed your first assurance report and established a good documentation process, future audits become easier to manage. Your control description and supporting evidence can be updated and reused, so you don’t have to start from scratch every year.

Absolutely. You’re free to choose a different auditor from one year to the next.

Maybe your needs have changed. Maybe you’re looking for a different working relationship. Or perhaps you’d simply like to see whether the audit process could be more efficient.

Switching auditors doesn’t mean starting over. Your existing reports, control descriptions, and documentation can help the new auditor plan the engagement. Every auditor must still conduct an independent assessment and obtain the necessary evidence each time an audit is performed.

That’s why it’s a good idea to start the conversation well before your next audit period.

At Loft Insight, we believe IT audits should be thorough without being unnecessarily complicated.

Our approach is simple: experienced IT auditors handle your engagement from start to finish. That means continuity, fewer layers of communication, and direct access to the people who understand your systems and controls.

We see an audit as a collaborative process, not an exam. You should know what we’re reviewing, why we’re asking for certain documents, and where things stand throughout the engagement.

By keeping our organization lean and administrative overhead low, we can also offer competitive pricing without compromising the professional work involved.

Whether you’re preparing for your first ISAE report or already have an established audit process, we’re happy to talk through your needs, with no obligation.

We can help you choose the right report, plan the audit process, and figure out the best way to get started.
