KYC, or Know Your Customer, is a process used by financial institutions and other regulated companies to verify the identity of their clients. This process helps prevent fraud, money laundering, and terrorist financing by ensuring that customers are who they claim to be. KYC procedures typically involve collecting and verifying personal information such as name, address, date of birth, and identification documents. In cybersecurity, KYC is crucial for establishing trust and maintaining regulatory compliance, especially in sectors like banking, cryptocurrency, and online financial services. Effective KYC practices help protect both businesses and customers from illegal activities and security threats.
