The pace of digital transformation across the financial services landscape continues to quicken. In a previous article, Accenture: fintech, cybersecurity and how to manage risk, we explored how that change is impacting the range and depth of data and cybersecurity threats faced by banks, insurtechs and fintechs worldwide. 

According to Accenture’s 2019 Ninth Annual Cost of Cybercrime report, financial services incurred the highest cybercrime costs among all industries studied in 2018.
