In a world where cyber threats are increasingly frequent and sophisticated, the role of the Chief Information Security Officer (CISO) has become essential to protect organizations. Working closely with the Chief Information Officer (CIO), they ensure that security requirements are considered from the design of architectures, infrastructures, and IT projects. But what exactly is a CISO? Also known as the French term Responsable de la Sécurité des Systèmes d'Information (RSSI), this professional guarantees the security, confidentiality, and integrity of data within an organization.
The CISO plays a central role in identifying cybersecurity risks, defining clear objectives, and implementing appropriate measures. The mission of the CISO also includes overseeing the security policy, managing incidents, and raising awareness among teams about information security. This strategic position, sometimes outsourced in certain organizations, helps reduce threats while optimizing available resources.
Whether you are a professional or simply curious, this article explores the challenges of the CISO role and suggests ways to strengthen its impact in cybersecurity.
What is a CISO?
A Chief Information Security Officer (CISO) is a professional specialized in defining, implementing, and managing information systems security within an organization. Their mission is to oversee security governance, reconciling business requirements with the principles of confidentiality, integrity, and availability of digital resources. Understanding the scope — and not just the definition — of this role is now a prerequisite for any organization committed to ensuring its sustainability in an ever-evolving digital ecosystem.
Main Responsibilities
The CISO has a multifaceted role, including:
- Defining the security objectives and needs of the organization.
- Evaluating and managing risks related to information systems.
- Organizing and overseeing security audits to identify vulnerabilities.
- Training and raising awareness among staff about information security.
- Managing cybersecurity incidents and ensuring the resilience of information systems.
Position within the Organizational Chart
Within an organization, the CISO often holds a strategic position. They maintain regular contact with the executive committee, business directors, as well as procurement, legal, and compliance officers to ensure security requirements are integrated across all decision-making processes.
Depending on the size of the organization, the CISO may manage a multidisciplinary team including SOC (Security Operations Center) analysts, Governance, Risk and Compliance (GRC) specialists, security engineers, or IAM (Identity & Access Management) managers. In some organizations, the CISO directly oversees an internal or outsourced SOC, responsible for detecting and responding to security incidents. This transversal and evolving role makes the CISO a central actor in preventing, detecting, and mitigating cyber threats.
Concrete Examples by Organization Size
In SMEs (Small and Medium Enterprises)
In SMEs, the CISO is often a versatile profile managing both information systems security and other IT aspects. In such contexts, an outsourced CISO sometimes becomes a strategic solution. With limited resources, they must act proactively to identify and fix vulnerabilities. They are key in ensuring adequate protection against emerging threats, optimizing costs while enhancing data security.
In Large Enterprises
In large enterprises, the CISO ideally reports to the Executive Committee and is supported by a clear mandate from the Board of Directors. The CISO must have:
- Decision-making power over budgets and technical priorities;
- Independent alert rights;
- Direct access to business units to ensure "security-by-design" and "privacy-by-design" integration.
The CISO typically leads a specialized cybersecurity team. They collaborate with various departments to integrate security into all aspects of operations, including new project development and regular security audits.
They ensure that information systems are secure, reliable, and compliant with applicable standards and regulations.
Daily Challenges of the CISO
The CISO role faces several major challenges that directly impact effectiveness and professional well-being.
Lack of Time and Resources
One of the main challenges CISOs face is lack of time and resources. In such situations, some choose to delegate responsibilities to an outsourced CISO. Studies show that 95% of CISOs exceed their working hours by about 10 hours per week, reflecting an excessive workload. The average CISO salary, while attractive, does not always offset the pressure associated with managing cybersecurity risks and incidents.
Regulatory Complexity
Cybersecurity regulations are increasingly complex and evolving, posing a significant challenge. Compliance with multiple standards and regulations, such as GDPR or sector-specific requirements, requires continuous monitoring and rapid adaptation. This legal complexity can consume a significant portion of the CISO's time and resources, diverting attention from other critical aspects of their role. In addition to technical, managerial, and communication skills, they must master legal areas: DORA, NIS2, CRA, HDS, GDPR… depending on the organization’s activities.
Lack of Visibility on Actual Security Status
CISOs often lack visibility into the actual security status of their organization. The proliferation of security alerts, many of which are false positives, reduces team productivity and complicates the identification of real threats. For example, in France, 45% of alerts triggered by endpoint monitoring and response tools were false, further complicating the challenges faced by CISOs.
Third-Party and Supplier Risk Management
Managing risks associated with suppliers and partners is another major challenge. Suppliers support business operations and economic development. However, they must not jeopardize the IS or strategic data. These two objectives are often difficult to reconcile.
CISOs must deal with third parties reluctant to implement security measures contrary to their business model and business units focused on speed and cost reduction. Additionally, some suppliers’ inability to meet security standards and the lack of a comprehensive third-party registry exacerbate these issues, increasing organizational risk.
Communication with Other Departments
Effective communication with other departments is a major challenge. CISOs must explain cybersecurity risks clearly and convincingly to legal, procurement, HR, finance, sales, or communications departments, often unfamiliar with technical issues. This cross-functional collaboration is essential to make security a collective and strategic lever.
To succeed, CISOs must build a cybersecurity strategy aligned with the organization's objectives.
In summary, CISOs operate in a complex environment. They must simultaneously manage constraints related to time, resources, regulations, visibility, and communication while ensuring the security and resilience of their organization’s information systems.
5 Levers to Facilitate the CISO Role
