Cyber crime is on the rise with cyber attacks and data breaches costing companies millions around the world. According to IBM’s Cost of a Data Breach Report 2026, conducted by the Ponemon Institute, the global average cost of a data breach has reached USD 4.99 million, a 12% increase on the previous year and the highest figure the report has recorded.
The evolution of the digital landscape in the business world has created an avenue for criminals to target organizations and their sensitive data from anywhere in the world. Security breaches are becoming a common occurrence with only the biggest being reported in the news. Due to this organizations and governments around the world have added cybersecurity as a critical function in their day to day operations. In line with this phenomenon, organizations have started hiring security professionals whose focus is on information security and cybersecurity at large.
Chief information security officers are guardians of an organization’s information and data security, they are responsible for the entirety of an organization’s information security profile, looking to defend it against any potential threats.
To perform their role effectively Chief Information Security Officers (CISO) require a multitude of technical and soft skills, such as the ability to make quick decisions, to lead, to communicate effectively and build relationships. Additionally, CISOs must adapt in order to maintain pace with the cyber threat landscape and new technologies, constantly learning on the job and picking up new skills. In this ever-shifting cyber world great CISOs require innovation and imagination in creating and delivering cyber security strategies for their organisations.
There is a common misconception that chief security officers and chief information security officers are interchangeable terms. Although the title of chief security officer can mean different things for different organizations. The title encompasses the role of an organization’s information security as well as its corporate security i.e. the physical security of employees and assets. On the other hand CISO is a term used to describe an individual in an organization whose only focus is on information security rather than corporate security.
Larger organizations can usually afford to have a dedicated CISO role in their hierarchy, however small to medium organizations may delegate the roles and responsibilities of a CISO to a chief information officer or chief technology officer.
Below are a list of common responsibilities associated with a chief information security officer:
These are just a few examples of the many tasks that chief information security officers are responsible for. Given the impact a cyber attack or data breach can have on an organization’s wellbeing, the importance of an individual overseeing the cybersecurity of an organization cannot be overstated. Organizations need to prioritise a strong cybersecurity strategy and hire an individual responsible for implementing it.
