The reasons the company gives

The company's own explanation, not something inferred from the numbers.

The number of companies using AI and attacks exploiting AI is increasing, while vulnerabilities also arise as systems are updated and specifications change. At the same time, penetration testing is generally limited to about once a year, and there is a shortage of cybersecurity professionals.
