From Compliance to Collaboration: The CPO’s Expanding Role in Cybersecurity

The Evolving Role of the Chief Privacy Officer in Cybersecurity 

As data privacy concerns grow and cyber threats become increasingly sophisticated, the Chief Privacy Officer (CPO) is playing an essential role alongside the Chief Information Security Officer (CISO) in safeguarding organizational data. Traditionally responsible for managing data privacy and regulatory compliance, today’s CPO now often collaborates closely with the CISO to ensure robust data protection that meets both regulatory and security needs. This convergence highlights the importance of well-defined roles, collaborative efforts, and the adoption of emerging trends to support effective data governance and cyber resilience.

Distinct Roles and Responsibilities: CPO vs. CISO

While the CPO and CISO share the common goal of protecting data, their roles focus on different aspects:

  • Chief Privacy Officer (CPO): Manages data privacy policies, compliance with regulations (e.g., GDPR, CCPA, HIPAA), privacy risk assessments, data subject requests, breach notification, and oversight of vendor privacy practices.
  • Chief Information Security Officer (CISO): Oversees cybersecurity policies, risk assessment, threat detection, incident response, data encryption, access controls, and employee security training, ensuring the technical safeguards around data.

Successful CPO and CISO Collaboration in Practice

  1. Privacy-By-Design at Apple: Apple is well-known for its privacy-by-design approach, embedding privacy protections from the start of product development. This is a prime example of effective CPO-CISO collaboration. Apple’s CPO and CISO work together to implement technical privacy controls and security measures directly into product architecture, ensuring customer data is safeguarded without compromising functionality. By incorporating both security and privacy perspectives early in the design phase, they align on privacy and security goals, a strategy that many organizations have adopted to prevent future risks.
  2. Incident Response at Marriott: After experiencing a significant data breach in 2018 that exposed over 500 million records, Marriott’s privacy and security teams overhauled their approach to incident response. The CPO and CISO collaborated on a new, integrated incident response plan that covers both technical breach response and regulatory obligations, including prompt notification to affected customers and regulatory authorities. This collaboration ensures that future incidents are managed efficiently, with coordinated efforts between privacy and security teams to address all aspects of breach response.
  3. Data Protection in Financial Services: A large financial services firm sought to enhance its data protection measures and incorporated collaboration between its CPO and CISO to ensure compliance and security. By implementing automated data discovery and classification tools, the CPO and CISO were able to locate and secure sensitive data across the organization. The CISO managed encryption and access controls, while the CPO ensured data was handled in line with privacy regulations. This joint approach protected the firm’s data, satisfied regulatory requirements, and improved customer trust.

Key Collaboration Areas and Emerging Trends

As organizations adapt to an environment where privacy and security are increasingly intertwined, the CPO and CISO often work together in several key areas. Emerging trends in technology and regulatory requirements further underscore the importance of this partnership.

  1. Data Protection Strategy and Privacy-By-Design:
    Privacy-by-design has become a central focus for many organizations, integrating privacy protections from the initial stages of development. Both the CPO and CISO collaborate to ensure privacy and security controls are embedded in data-handling processes and product architectures. With privacy-enhancing technologies (PETs) like differential privacy and homomorphic encryption gaining traction, the CPO’s regulatory knowledge and the CISO’s technical expertise are essential for implementing these advanced technologies effectively.
  2. Risk Management with Integrated Risk Management (IRM):
    Many organizations are adopting Integrated Risk Management (IRM) frameworks, where privacy and security risk assessments are handled within a single system to offer a unified view of organizational risk. The CPO and CISO assess privacy and security risks together, with the CPO focusing on data-handling practices and regulatory compliance, and the CISO concentrating on technical security risks. This approach streamlines the process, reducing silos and allowing both roles to take preemptive action to mitigate data-related risks.
  3. Incident Response and Breach Management:
    In the event of a data breach, the CISO leads technical containment and investigation efforts, while the CPO manages communication with affected individuals and regulatory authorities, ensuring compliance with notification requirements. For instance, during the Equifax breach, delays in regulatory communication highlighted the importance of timely and coordinated efforts between privacy and security teams. Today, many organizations have learned from such incidents and are building integrated incident response plans that allow the CPO and CISO to collaborate seamlessly, reducing delays and ensuring a comprehensive approach.
  4. Vendor Management and Privacy-Enhanced Data Sharing:
    With the increased reliance on third-party vendors, CPOs and CISOs collaborate to assess vendor risks comprehensively. Privacy-enhanced data-sharing solutions, like federated learning and anonymization tools, allow organizations to work with vendors without compromising sensitive data. The CPO reviews vendor compliance with privacy laws, while the CISO evaluates the security practices and technical controls the vendor has in place. This combined approach helps organizations address both privacy and security risks, ensuring vendors align with organizational standards.

Collaboration Challenges and Solutions

Despite the benefits, CPO-CISO collaboration can face several challenges:

1. Role Ambiguity and Overlap:

    • Challenge: When responsibilities between the CPO and CISO are not clearly defined, it can lead to duplication of efforts or missed accountability. For example, if both roles assume the other is responsible for vendor risk assessments, this oversight could leave the organization exposed to compliance risks.
    • Solution: Establish clear boundaries and responsibilities in a formalized governance structure, defining which role owns specific tasks. Some organizations set up cross-functional privacy and security committees to ensure transparency and facilitate collaboration on overlapping duties.

    2. Differing Priorities and Communication Gaps:

    • Challenge: Privacy and security teams often prioritize differently. For instance, the CISO may focus on implementing technical controls quickly to address security gaps, while the CPO may emphasize thorough regulatory compliance, potentially causing delays if not aligned.
    • Solution: Regular, structured communication—such as weekly check-ins or shared project management tools—can help synchronize priorities and align goals. Building a shared understanding of each other’s objectives fosters respect and better alignment on data protection strategies.

    3. Resource Constraints:

    • Challenge: As both privacy and security roles grow in scope, limited resources can make it difficult for teams to fulfill all responsibilities. This is particularly challenging in smaller organizations where the CPO and CISO may not have dedicated teams.
    • Solution: Many organizations are turning to automation tools and artificial intelligence (AI) for tasks like data classification, monitoring, and risk assessment. Automating routine tasks allows the CPO and CISO to focus on higher-level strategy and collaboration. Allocating budgets to adopt Integrated Risk Management platforms can also streamline privacy and security efforts, making it easier to manage risks comprehensively.

    4. Balancing Privacy and Security:

    • Challenge: While privacy and security are complementary, they sometimes conflict. For example, the CISO may favor increased data monitoring to detect threats, but this could conflict with the CPO’s privacy obligations to minimize data collection.
    • Solution: Implement privacy-enhancing technologies that allow security without sacrificing privacy, such as differential privacy for data monitoring. The CPO and CISO should work together to evaluate new technologies that support both privacy and security needs, ensuring organizational compliance and resilience.

      The Future of CPO-CISO Collaboration

      As privacy and cybersecurity converge, the collaboration between CPOs and CISOs is expected to deepen. Emerging trends suggest that some organizations may even combine these roles into a Chief Privacy and Security Officer (CPSO), creating a unified approach to data protection. The rise of Integrated Risk Management and privacy-enhancing technologies will likely drive further alignment, allowing privacy and security teams to work seamlessly within a cohesive data governance framework.

      By embracing shared responsibilities, leveraging new technologies, and addressing collaboration challenges, CPOs and CISOs can enhance their organizations’ resilience against data breaches and regulatory risks. As privacy and security become increasingly essential to business success, organizations that prioritize strong CPO-CISO collaboration will be better equipped to protect their data, maintain trust, and adapt to an evolving threat landscape.
