Let us learn more about his journey:

Common Cybersecurity Challenges

Thierry recognizes that challenges vary across sectors and specific contexts, but he identifies three common issues that are particularly pervasive.

Firstly, there’s the Asymmetry of Offense. This concept refers to the reality that attackers often find it easier and cheaper to mount attacks than defenders do to prevent them. New technologies, while offering numerous benefits, can exacerbate this problem by introducing new vulnerabilities and attack vectors. The use of AI is a prime example, potentially increasing the asymmetry even further.

Secondly, Thierry highlights the Talent Shortage as a significant challenge. There is a notable gap between the demand for skilled cybersecurity professionals and the available supply in the market. This shortage hampers organizations’ abilities to defend against threats effectively. Despite growing awareness of cybersecurity and the proliferation of educational programs, the number of qualified professionals remains insufficient to meet demand. Furthermore, high stress and burnout rates contribute to retention issues within the field.

Lastly, Thierry’s preferred challenge is Organizational Embedment. This involves embedding cybersecurity within the organizational structure in such a way that costs are balanced between effort and security. It means integrating security into all aspects of the business and ensuring it’s perceived as a shared responsibility across departments. Achieving effective security by design necessitates a shift from reactive to proactive security measures, increased cross-department collaboration, and greater executive involvement. For a CISO, this represents the ultimate challenge.

Essential Skills for Effective CISO Leadership

Thierry emphasizes the importance of a CISO focusing on the entire organization, its crown jewels, and critical processes. He believes that the organizational culture must align with both business goals and the objectives of adequately protecting customer data. To achieve this, security organizations and departments should define key tenets that drive the right team behaviors. This approach necessitates working with and influencing the most senior members of the organization in a highly transversal manner.

Thierry is a strong advocate for establishing key guardrails, platform-level technical controls, and principles for the company to align with. He asserts that this strategy has the advantage of fostering a consistent mindset across the organization over the years, enabling the capture of low- hanging fruit and allowing other issues to be addressed iteratively.

Thierry identifies several skills as most useful for a CISO in a typical large organization: business acumen, leadership, organizational culture, negotiation, and risk management. These competencies are crucial for navigating the complexities of modern cybersecurity and ensuring that security measures support and enhance business objectives.

From Tech Focus to Organizational Leadership

Thierry observes that, across all industries, the role of the CISO is evolving from a primarily tech-focused position to a broader organizational and leadership role. More and more, CISOs are being engaged by boards for strategic advice, a significant shift from the situation ten years ago. He views this as a positive development, as security, even in the digital age, is fundamentally an organizational and cultural matter.

Thierry is cautious about the growing discussion around the liability of the CISO role. He believes this notion stems from a somewhat naive understanding of a CISO’s responsibilities. In most large organizations, security responsibilities are distributed across many lines of business (LOBs) and functions, many of which do not even report to the CISO.

However, Thierry acknowledges a net positive in this trend. It encourages organizations to take the role more seriously, consider its alignment, and recognize the board exposure it requires. This shift can lead to more strategic thinking about security and its integration into the broader organizational framework.

Enhancing Compliance and Resilience Across the EU

Thierry believes that cybersecurity and privacy regulations have become more descriptive, applicable, and useful over the past decade. Despite the EU’s strategy to defragment regulations, the result is still a landscape of fragmented requirements, regulators, and overlapping mandates within industries. The NISD2 and DORA are recent examples of this.

Thierry recommends greater harmonization and coordination among regulators. Creating unified frameworks that apply across multiple sectors can help reduce the complexity and overlap of requirements.

Additionally, providing clear guidance and support for organizations to navigate these regulations can ease the compliance burden. Continuous dialogue between industry and regulators is also essential to ensure that regulations are practical, effective, and adaptable to the evolving threat landscape.

Overall, Thierry sees a net positive in the increasing regulations. They have led to a higher baseline of cybersecurity and privacy standards across the EU, protecting individual organizations and contributing to a more secure and resilient digital ecosystem. Clear regulations help organizations understand their obligations and foster a culture of security and privacy by design.

Navigating the Evolving Intersection of Technology and Compliance

The constantly evolving relationship between technology and compliance presents a complex and multifaceted challenge for organizations. Regulations can be either descriptive, offering flexibility in implementation, or prescriptive, mandating specific actions. Descriptive regulations are generally easier to comply with, as companies can tailor them to their specific needs.

This dynamic has led to the emergence of specialized job roles dedicated to navigating this intersection. These professionals focus on understanding the intent behind regulations and translating them into risk-management measures that support the organization’s mission while considering economic constraints.

Data protection, cybersecurity, and digital operations are prime examples of areas where technology and compliance converge. To navigate this complex landscape effectively, organizations need a proactive and integrated approach.

As technology advances, regulatory frameworks are established or adapted to address emerging risks and ensure secure and ethical operations. However, the lengthy legal and regulatory processes can struggle to keep pace with rapid technological change. A five-year timeframe, like the one seen with the Digital Operational Resilience Act (DORA), can leave regulations outdated upon.

This highlights the need for a balanced approach to cybersecurity frameworks. A mix of prescriptive and descriptive elements, combined with a foundation of principles and frameworks, can be the answer. Mandating key risk-reducing activities for the European market, coupled with independent audits and strong internal controls, can ensure the overall objectives are met.

A proactive and integrated approach translates to establishing unified control frameworks, anticipating future regulatory changes, and embedding compliance into the organization’s core processes and culture. Shifting from viewing compliance as an afterthought to a fundamental aspect of strategic planning and daily operations is crucial for success in this ever-changing landscape.
