Chief Information Security Officer (CISO)

Image of a CISO considers security optionsA chief information security officer (CISO) is one of the latest additions to enterprise C-suite roles, offering executive oversight, strategic vision, and management of an organization’s IT security operations. As global organizations adopt more IT infrastructure, the cybersecurity of client and proprietary data is progressively critical, prompting the need for CISOs.

This article looks at the role of CISO, how it compares to other executive positions, the necessary skills and responsibilities, and the prospective road to becoming a CISO.

What is a Chief Information Security Officer (CISO)?

Chief Information Security Officers (CISOs) are the executive leaders responsible for an organization’s IT environment’s cybersecurity and digital risk management posture. First adopted in the mid-1990s, CISO positions often lead security-specific IT personnel and report to the company’s Chief Information Officer (CIO) or directly to the Chief Executive Officer (CEO).

CISO vs Similar C-Suite Roles

The CISO often gets compared to other executive roles for enterprise organizations in the digital era, including Chief Risk Officer (CRO), Chief Technology Officer (CTO), and Chief Data Officer (CDO).

Role Manages … Reports to …
CIO Internal IT infrastructure and resource development CEO
CRO Risk posture, regulatory compliance, and mitigation strategy CEO
CISO Detection, prevention, and response and cybersecurity systems CIO or CEO
CTO Emerging IT solutions and product technology CIO or CEO
CDO Leveraging analysis of organization-wide data and systems CIO or CEO


Chief information officers have long been the overarching IT leaders for organizations. Of the executive-level positions listed, CIO and CRO are typically the two most senior roles, with CISO, CTO, and CDO reporting to the CIO. Still, a wave of newer positions has led to CTO and CDO roles taking on many of the same responsibilities.

While CISOs increasingly interact with risk management through data protection, CROs usually hold a background in accounting, law, underwriting, or economics and manage the entirety of an organization’s risk management strategy and enforcement.

CISO Skills and Responsibilities

  • Hire, lead, and delegate responsibilities to an information security team
  • Execute vision and long-term cybersecurity strategy for an organization
  • Knowledge of regulatory compliance standards for organization data security

How To Become a CISO

Because information technology – and cybersecurity, by extension – are maturing and vital parts of SMB to enterprise organizations, veteran CISOs are a rare commodity. Traditional academia only recently started offering advanced IT and cybersecurity-specific degrees, meaning most of today’s CISOs trained and learned the game through self-learning and experience.

Besides spending years in a SOC, routes to gaining the needed expertise include:

  • Academic degrees (BS, MS, PhD) in computer science, IT, or cybersecurity
  • Boot camps offering cybersecurity-specific training and accreditation
  • Vendor-neutral industry certifications for cybersecurity professionals

Computer Science and Cybersecurity Degrees

Computer science and cybersecurity degrees from traditional universities and colleges are a maturing academic discipline with many undergraduate and graduate degree options to choose from. Professionals with degrees in engineering, business, and law are also suitable when considering the rarity of cybersecurity doctorates.

The length of terms and tuition rates for undergraduate, graduate, and doctoral studies varies by school and program. Several universities offer a bachelor’s (BS) or master’s (MS) of science in computer science or information technology with a concentration in cybersecurity, if not a full-fledged major. Courses and concentrations include information security leadership, digital forensics, data compliance, and ethical hacking.

Cybersecurity Boot Camps

After the success of coding boot camps offering in-person and remote training programs to develop a generation of software developers, cybersecurity boot camps have been the natural extension for building expertise and accreditation in IT security. 

Boot camps can offer classroom education and training like this group with Fullstack Academy.

Many programs – some attached to traditional universities – offer intensive boot camps of varying length, tuition, and concentrations. Typical cybersecurity boot camps can last from 6 to 24 weeks and cost anywhere from $5,000 to $20,000, depending on the service provider.

History of the CISO Role

In 1995, Citigroup hired the first-known instance of a CISO by appointing budding IT security leader Steve Katz. CISOs are increasingly a part of enterprise executive teams in the past decade and traditionally report to the CIO. With growing attention on cybersecurity, some CISOs report directly to CEOs and sit on par with CIO leaders.
