Trust centre: attestations and recognitions

SD Worx HR Tech Awards 2022

Our marketing and communication department can only do so much to show you that SD Worx is a reliable payroll and HR partner. Even more, independent attestations and recognitions often speak louder than any customer testimonial. That’s why we’ve created this Trust Centre with our most telling credentials.

SD Worx … a story of trust

SD Worx HR Tech Awards 2022


Payroll isn’t just an essential business function, it plays a vital role in your culture as well. On top of that, payroll-related data have become one of the most important assets in a company. Payroll processing, however, doesn’t have to be time consuming and complicated. Not with an experienced payroll partner like SD Worx. Our leading payroll services and powerful payroll technology are subjected to regular independent reviews to demonstrate how we succeed at sparking success in the heart of your business.


    ISAE 3402 attestation

    The widely recognised ISAE 3402 standard issued by the International Auditing and Assurance Standards Board (IAASB) is an assurance standard developed specifically for outsourcing activities that are related to processes with a financial impact, such as payroll. SD Worx doesn’t stop there. We also cover a set of key IT supporting processes to provide you with an end-to-end view over the services we deliver. On an annual base, an independent auditor assesses the quality of our (payroll) outsourcing services. The subsequent ISAE 3402 report discloses all control activities and processes, including the auditor’s opinion.

    SD Worx issues annual ISAE 3402, type 2 reports over selected payroll products and services. The report not only includes the service description of the controls, but also confirms we have executed the controls correctly over a certain period of time.
