Foundation Launches ISAE 3402 Register to Boost Transparency

• The ISAE 3402 register makes it easier to find reliable service organizations by listing publicly available assurance information

• Any organization with an ISAE 3402 Type I or Type II statement can register for free to increase transparency

• ISAE 3402 helps outsourcing parties manage risk by showing that service organizations have controls in place

Next, picture signing a contract with a payroll processor, cloud host, or claims administrator using only polished marketing pages and a sales deck. The service might work fine, but if a control fails, you still own the operational risk, the customer impact, and the clean-up work.

That said, outsourcing changes what stakeholders expect you to prove. As vendor chains get longer and more critical, many industries now treat ISAE 3402 as a baseline requirement because it gives a structured way to see what controls exist, what period they cover, and what was tested.

By the end of this section, you should be clear on what an ISAE 3402 register is, who should use it day to day, and how it helps you compare providers with evidence instead of claims.

Next, the ISAE 3402 register is a public-style reference point that shows whether a service organization has an ISAE 3402 report, what type it is, and whether it is currently available. The practical purpose is simple: give stakeholders visibility into the existence and availability of assurance information that is qualitative (describes controls, not just numbers) and transparent (clear scope, period covered, and who the report is meant for).

This matters most when you are doing due diligence under time pressure. Instead of asking five different vendors for “some audit evidence” and getting back inconsistent PDFs, you can start with one question: is there an ISAE 3402 report you can request and review, and is it up to date.

Also, the broader goal goes beyond convenience. A shared register makes it easier to map the reliability of service organizations across a supply chain, because buyers can quickly identify which providers have independent assurance and which do not.

That said, the register does not replace reading the report or testing your own vendor requirements. What it changes is the starting point for risk conversations, from “do you have anything” to “here’s the assurance you say exists, now let’s confirm scope and fit,” which also nudges more service organizations to adopt ISAE 3402 when customers begin to expect it as the baseline.

Next, it helps to separate two questions people mix up: who is allowed to register, and what others can learn from the register.

Eligibility is simple. Organizations that already hold an ISAE 3402 statement, Type I or Type II, can register free of charge. If you are still preparing for your first statement, registration usually comes after you have the final statement in hand, so the entry can be tied to an actual assurance report rather than a plan or a promise

The practical value is mostly on the buyer side, where time is lost comparing vendors and chasing evidence.

• Quicker due diligence: procurement teams can confirm whether a vendor has an ISAE 3402 statement early, before weeks of email back and forth

• Easier vendor comparisons: a shortlist of 3 to 5 suppliers becomes easier to screen when assurance info is consistent across entries

• Clearer assurance trails for customers: risk, compliance, and audit teams can point to a single reference during onboarding, renewals, or an annual review cycle

Here’s the catch: the register speeds up the first pass and the documentation trail, but it does not replace reading the statement itself. If you do one thing, use the register to narrow the field, then ask finalists for the full Type I or Type II report to confirm scope, period covered, and any exceptions

Also, outsourcing does not outsource accountability. Even when a payroll provider, fund administrator, or IT host runs the process day to day, the organization that outsourced the work still owns the risk in the eyes of its board, investors, and auditors. If a key control fails at the service provider, the impact usually lands back on management.

A practical signal of being “in control” is being able to show what controls exist, who performs them, and how they are checked over a defined period, often 6 to 12 months. That is where ISAE 3402 helps: it provides third-party reporting on controls at a service organization that supports outsourced activities. Instead of relying on a sales deck or a one-time questionnaire, stakeholders can review an independent report describing the control objectives, the control design, and whether those controls operated as described during the period.

If you do one thing, ask which outsourced processes are most tied to financial reporting or investor reporting, then map each one to the relevant ISAE 3402 report. ISAE 3402 works best when the provider’s scope matches the exact service you rely on, and fails when the report is broad but misses your specific handoffs.

Common mistake: treating any assurance report as “good enough.” Fix it by checking a few specifics before you file it away:

• Confirm the report period lines up with your year-end or reporting cycle

• Verify the services in scope match what you actually outsourced, such as NAV support, payment runs, or access administration

• Look for complementary user entity controls, meaning controls you must perform on your side for the provider’s controls to hold

• Review exceptions and how they were remediated, not just the overall opinion

Next, hold on to this line as you review vendors and renew contracts: “Transparency turns trust from a promise into proof.” When a supplier can show what controls they run, who owns them, and how they test them, the conversation shifts from reassurance to evidence.

So ask yourself one practical question as you shortlist, renew, or expand a critical vendor relationship: what would change in your vendor decisions if every critical supplier could demonstrate they are truly in control? For a procurement lead, it might mean fewer exceptions and faster renewals; for a security manager, clearer follow-ups and fewer blind spots; for a finance owner, less time chasing answers during audits. If you do one thing, make “show me how you stay in control” a standard checkpoint before the next renewal cycle.
