The impact of cybercrimes is expected to increase exponentially by 2025 to reach approximately $10.5 billion. In CY 2022, cybersecurity breaches had an estimated global economic impact of $6 billion and the average reported cost per cybersecurity breach was $4.35 million. Investors have recognized the need and potential for this mega-industry which equals a country’s GDP and is greater than the GDPs of most countries. We have seen an increase in venture capital, private equity and global mergers and acquisitions, as well as a vibrant startup ecosystem offering a complex range of cyber defense solutions.

Zero Trust cybersecurity is a security model that assumes that any network, device or user can be compromised and therefore requires authentication and authorization to access resources. As highlighted by the World Economic Forum (WEF), there is an urgent need for governments and business leaders to embrace zero-trust cybersecurity in the current global economic and socio-political environment.

The zero-trust approach that encourages us to “never trust and always verify” can help restore digital trust by limiting access to sensitive information and systems to those who have been verified and authorized, thereby reducing the risk of unauthorized access or data breach. Additionally, it can also help organizations comply with regulatory requirements and industry standards for data security.

The principles that define a zero-trust architecture are:

  • All data and services are resources

  • All communications are secure regardless of location

  • Access to corporate resources is session-based

  • Access to resources is determined dynamically

  • Continuous security posture monitoring

  • Strict authorization and access control

  • Continuous improvement of data collection and application

  • Integration with enterprise detection and response

Investing in Zero Trust cybersecurity can include a variety of different technology solutions and services. Some common investments organizations can make to implement a zero-trust model include:

  • Identity and Access Management (IAM) solutions: These solutions can be used to verify the identity of users and devices and control access to resources based on predefined policies.

  • Multi-factor authentication (MFA) solutions: These solutions can be used to add an extra layer of security by requiring users to provide multiple forms of authentication before accessing resources.

  • Network segmentation solutions: These solutions can be used to segment networks and isolate sensitive data and systems from the rest of the network.

  • Endpoint security solutions: These solutions can be used to protect endpoints such as laptops and mobile devices from malware and other threats.

  • Cloud security solutions: These solutions can be used to secure cloud environments and protect data and systems hosted in the cloud.

  • Security Information and Event Management (SIEM) solutions: These solutions can be used to monitor and analyze security-related data from a variety of sources to detect and respond to threats.

  • Professional Services: Organizations can also invest in professional services such as security assessments, penetration testing, and incident response planning to help identify vulnerabilities and develop a robust security strategy.

The size and type of investment in zero-trust cybersecurity will depend on the organization’s specific needs and requirements, the size of the organization, as well as the organization’s technology maturity, risk tolerance and the results of a solid feasibility analysis.

The impact of zero trust cybersecurity can vary depending on the specific industry sector and the types of data or systems being protected. Here are examples of the implementation of a zero trust model in various industries:

Zero-trust cybersecurity architecture, as described by the National Institute of Standards and Technology NIST, can have a profound impact on data governance, as it can help secure sensitive data and systems across various industries by verifying user and device identities, and limit access to resources based on predefined policies tied to specific regulatory guidelines or business rules.

However, many challenges are encountered when deploying zero trust cybersecurity, such as cost, interoperability, alignment with other strategic business priorities, alignment with ethics and risk programs , etc.

What can C-suite leaders do to be better prepared for success when planning a zero-trust strategy? They can focus on building a culture of cyber resilience, which results in increased cyber literacy and cyber fluency for the company’s general workforce, and optimize ( through development and requalification) the cyber-specific skills of their technical team. Workforce management efforts should be complemented by proactive deployment of a digital ethics program and honest SWAT assessment in the face of the growing sophistication of cyberattacks globally. Performing a robust FMEA analysis is a must for companies that want to maintain or gain a competitive advantage. Assessing and reviewing the company’s existing internal cyber capabilities, versus the option of forging strategic partnerships or perhaps pursuing a potential cyber acquisition, should also be on the agenda. . Designing and deploying cyber metrics is a critical step that requires alignment with other financial, operational, and ethical metrics in the business dashboard. Last, but not least, forward-thinking leaders must embrace innovation and continuously improve their cyber defense program to dynamically adapt to the rapidly changing cyber landscape.

Futurists envision cyber-resilient programs that will most likely include satellite internet, human-machine interfaces, cyber-digital twins, quantum technology, federated learning, and more.

ESG-conscious globalists and leaders hope that our transition to future iterations of the World Wide Web, such as Web 3.0 and Web 4.0, will have state-of-the-art cyber defense programs and align with the times on the United Nations SDG 2030. as with the UN 2050 net zero agendas.
