SOC 1 Reporting

The report your customers\u2019 auditors ask for when your service affects their financial statements. Different question from SOC 2, and frequently needed alongside it.

What is SOC 1?

Controls that touch your customers\u2019 financial reporting

A SOC 1 report is an attestation, performed under SSAE 18 and AT-C 320, on the controls at a service organisation that are relevant to its customers\u2019 internal control over financial reporting. If what you do feeds your customers\u2019 numbers, their external auditors need assurance over your controls in order to sign off their accounts, and SOC 1 is how they get it.

It is often confused with SOC 2, and the distinction is about audience rather than rigour. SOC 2 answers a security question and is asked for by security and procurement teams. SOC 1 answers a financial reporting question and is asked for by finance teams and external auditors. Payroll providers, payment processors, claims administrators, benefits administrators and parts of fintech frequently need both, for different people at the same customer.

Type 1 and Type 2 exist inside SOC 1 just as they do inside SOC 2. A Type 1 reports on control design at a point in time. A Type 2 covers a period, normally six to twelve months, and tests whether the controls actually operated. Auditors almost always want Type 2, because a point-in-time report tells them nothing about the year they are auditing.

Compliance requirements

What a SOC 1 examination covers

Control objectives are defined by you rather than prescribed, which is what makes scoping the hardest part.

Control objectives and system description

You define the control objectives relevant to your customers’ financial reporting and describe the system. Management asserts this is accurate, and the auditor tests it.

Transaction processing integrity

Completeness, accuracy, authorisation and timeliness of the transactions you process on a customer’s behalf.

Logical access

Who can reach the systems and data that affect financial reporting, how that access is granted, reviewed and removed.

Change management

Changes to the relevant applications and infrastructure authorised, tested and approved, evidenced across the whole period.

IT general controls

The ITGC layer beneath everything else: job scheduling, backup, and the operational controls the transaction controls depend on.

Complementary user entity controls

The controls your customers must operate at their end for your objectives to be met. Stating these clearly prevents an argument later.

Audit process

From applicability assessment to regulatory submission

Netru manages the complete CAF compliance journey, from determining applicability through to competent authority submission and ongoing improvement.

01

Scoping and Control Objectives

We work out which of your services actually touch customer financial reporting and draft control objectives that are defensible without being unnecessarily broad.

02

Type 1 or Type 2 Decision

We confirm what your customers’ auditors will accept, and set the observation period backwards from their year end rather than from yours.

03

Readiness Assessment

We assess your current controls against the drafted objectives and produce a remediation plan before the auditor is engaged.

04

System Description

Your compliance manager writes the system description that management will assert to, which is the document the report is built around.

05

Evidence and Operating Effectiveness

We put the evidence generation in place for the observation period, because a Type 2 tests the whole period rather than the week before fieldwork.

06

Audit Management

We manage the CPA firm through fieldwork and handle requests, findings and the path to a clean opinion.
