A CISO, or Chief Information Security Officer, is a senior-level executive responsible for establishing and maintaining an organization’s information security program, ensuring the protection of data and systems from cyber threats and compliance with relevant regulations. These people can be internal and increasingly external. They can be full-time or fractional, like we offer at TEKRiSQ through various CISO services. Also See Senior Agency Information Security Officer.

A Chief Information Security Officer (CISO) is typically someone who performs this role full-time, but many can for a limited period of time, or on an ongoing basis as a service to the company. This can reduce costs, and serve a strong purpose for companies who do not need a full-time resource.
