Financial cybersecurity is the set of strategies and technologies designed to protect banking systems, personal data, and transactions against cyberattacks. With the rise of digital banking and electronic payments, online fraud has grown, making it essential to have tools such as biometric authentication, encryption, and real-time transaction monitoring. Financial companies invest in artificial intelligence to detect threats before they occur, protecting both users and institutions. Cybersecurity is not only a necessity but a key factor in maintaining trust in the digital financial system.
