Plain English:
What Is a Chief Information Security Officer (CISO)?
A Chief Information Security Officer, or CISO, is the person responsible for protecting a company’s data and technology systems from threats like hackers, viruses, and data breaches.
Think of the CISO as the head of cybersecurity. They make sure the company has the right tools, policies, and training in place to keep sensitive information safe — whether it’s customer data, employee records, or financial details.
The CISO also helps the business stay compliant with laws and regulations, prepares for possible cyberattacks, and leads the response if something does go wrong.
In simple terms, the CISO’s job is to keep the digital side of the business secure and trustworthy.
