The Information Technology Audit and Assurance unit of Nexia SAB&T provides services that address organisations exposure to new and emerging risks stemming from changes in the environment in which businesses operates as they become more dependent on technology to support business processes.

- Full dependence or reliance on services provided by application system vendors
- Inadequate level of information security for the environment, which could lead to system vulnerabilities
- Inadequate level of user management within the IT applications which could lead to data leakage, loss or manipulation
- Limitation of normal operations due to unreliable systems availability

Computer Assisted Audit Techniques (CAATs)
Businesses may process thousands or even many millions of transactions every year. To properly test that controls are operating effectively and consistently is virtually impossible using traditional audit methods. CAATs allow auditors to determine whether a control has operated effectively for every transaction as easily as testing a single one using traditional methods.
Continuous auditing is an automated method used to perform auditing activities, such as control and risk assessments, on a more frequent basis. Technology plays a key role in continuous audit activities by helping to automate the identification of exceptions or anomalies, analyse patterns within the digits of key numeric fields, review trends, and test controls, among other activities. Not only does it enable the integrity of information to be evaluated at any given point in time, it also means that the information is able to be verified constantly for errors, fraud, and inefficiencies. The activity is continuous in that it allows for testing throughout the year as opposed to an end of year snapshot.
