As the end of another busy tax season approaches, it is important for accounting firms to remember their obligations related to data security. Accounting firms maintain a significant amount of data on behalf of their own employees and clients. These firms house financial records, tax information, corporate intellectual property, legal documents, healthcare records, and/or other privacy information, all of which is valuable to cybercriminals. This data can be used for ransom, filing fraudulent tax returns, or sold on the dark web. Should this occur, firms could face a loss of reputation, clients, and money. In the months leading up to April, the number of client engagements (and data) increases significantly, in turn, increasing risk.
