Over time, as the cyber threat landscape continued to evolve, the CISO’s responsibilities expanded, with increasing involvement in policy development, risk management, and collaborating with other C-level executives to align cybersecurity strategies with broader business objectives.

The Changing Role of the CISO | Establishing Cybersecurity at the Executive Level and Beyond

Although the role of the CISO now can vary widely across organizations depending on their size and nature, it tends to lean much further into executive leadership and risk management, with a prime responsibility to keep C-suites in touch with security risks relating to organizational objectives, strategy and business outcomes.

Depending on the organization, the modern CISO will be involved in most of the following key areas of responsibility to some degree or another.

  • Cyber risk management
  • Compliance and regulatory adoption
  • Strategic business integration
  • Crisis management & Incident Response
  • Establishing & cultivating a ‘Security First’ business culture

Let’s take a look at each of these in turn.

Cyber Risk Management

Central to the role of many CISOs is the responsibility for adopting a proactive and strategic approach to identify, assess, and mitigate cyber risks. This often includes developing comprehensive risk management frameworks that align with organizational goals.

Engaging actively with executive leadership, CISOs work to articulate the potential impact of cyber threats on business operations, financial stability, and company branding, collaborating where needed with department leads across the organization to foster a culture of cybersecurity awareness and compliance.

Compliance and Regulatory Adoption

CISOs play a central role in ensuring regulatory compliance, which involves both ensuring adherence and understanding the implications of regulations on day-to-day processes and overarching strategies.

Staying knowledgeable of regulatory changes and translating them into actionable policies is a shared responsibility that CISOs undertake to safeguard data privacy and integrity.

In collaboration with legal and compliance experts, CISOs navigate the intricate frameworks of requirements and controls set by GDPR, HIPAA, or PCI DSS, for example, and then tailor security measures to meet these standards. In addition, CISOs are counted on to cultivate a culture of continuous compliance through measures such as conducting regular audits and mechanisms to address and identify gaps.

In doing so, they help to not only mitigate legal and financial risks but also fortify the organization’s reputation and stakeholder trust.

Strategic Business Integration

The evolving nature of the role can be seen in the way that many CISOs are now increasingly viewed as critical enablers in the business ecosystem. In some organizations, their insights and expertise have become invaluable in shaping product development and influencing business strategies by driving technical innovation.

In this regard, they can be key to enhancing relationships with vendors and partners, fostering a security-centric approach in all business interactions and collaborations.

Crisis Management and Incident Response

With cyber threats becoming more sophisticated and pervasive, the modern CISO is not only tasked with preventing security breaches but also with orchestrating a robust incident response (IR) strategy.

They will play a central role in the development and implementation of incident response plans (IRPs), ensuring leaders from all functions are well-prepared in the event of a cyber incident. In many organizations, CISOs collaborate with cross-functional teams, including legal, communications, and IT, to streamline response efforts during a crisis.

In some cases, the role may extend to leading post-incident analyses to understand the root causes and improve response protocols. This typically involves actively engaging with external stakeholders, regulatory bodies, and law enforcement agencies to navigate the legal and reputational ramifications of a security incident.

As crisis managers, CISOs may be expected to steer the organization away from negative fallout after cybersecurity incidents with a strategic and agile approach, minimizing the impact of breaches and maintaining business continuity.

Establishing & Cultivating a ‘Security First’ Business Culture

The modern CISO recognizes the significance of cultivating a robust security culture within the organization. They champion awareness programs, training initiatives, and communication strategies to instill a collective responsibility for cybersecurity among employees.

At the same time, CISOs may be at the forefront of advocating for advanced technologies and innovative solutions to counter evolving cyber threats, leading the evaluation and implementation of cutting-edge tools, artificial intelligence (AI), and machine learning (ML) to fortify their organization’s defenses.
