Performing thorough input checks is essential primarily to minimize security vulnerabilities. Input checks, often referred to as input validation, are mechanisms that help ensure that the data entering a system is both accurate and secure. When user inputs are not properly validated, it opens the door for various security threats such as SQL injection, cross-site scripting (XSS), and buffer overflow attacks. These vulnerabilities can lead to unauthorized access, data breaches, and other malicious activities that compromise the integrity and confidentiality of the system.

By validating inputs, systems can reject or sanitize potentially harmful data, thereby reducing the risk of exploitation and maintaining a secure environment. Proper input validation acts as a first line of defense against various types of attacks, thus protecting both the users and the infrastructure.

While compliance with international regulations, enhancing user experience, and simplifying debugging processes are also important, they do not capture the primary criticality of thorough input checks as effectively as the focus on security vulnerabilities does.
