Legacy System Modernization for Banks Market Momentum: Key Driver Expected To Boost Growth Through 2030
An escalating emphasis on cybersecurity and adherence to regulatory standards is projected to fuel expansion within the legacy system modernization for the banks market. These terms, cybersecurity and regulatory compliance, involve protecting systems or data and fulfilling the compulsory controls, reporting, and audit stipulations imposed by financial regulatory bodies. This heightened attention to cybersecurity and regulatory compliance stems from a surge in cybercrime reports and increasing financial damages documented by authorities. Updating outdated core systems and channels facilitates more robust controls (such as encryption, identity verification, and logging), quicker vulnerability patching, and automated proof of compliance, thereby assisting banks in satisfying their security and audit responsibilities. For example, in March 2023, the Federal Bureau of Investigation (FBI), a US-based primary federal law enforcement agency, reported that in 2023, 880,418 complaints were filed, representing nearly a 10% rise vs. 2022, and associated losses surpassed $12.5 billion (an increase of 22% year over year). This data highlights the growing threat landscape that compels investments in security and compliance. Consequently, the growing concentration on cybersecurity and regulatory compliance is a key driver for the legacy system modernization for the banks market.
