New CISO vs CTO Who Owns Cybersecurity in 2025?

New CISO vs CTO

INTRODUCTION

With increasing cyber threats and regulatory demands, cybersecurity has become the core of business strategy. Companies in various sectors are raising a very important question: “New CISO vs CTO—who owns cybersecurity in 2025?”

This debate is a manifestation of a larger shift in leadership positions. Although the Chief Technology Officer (CTO) has traditionally borne responsibility for technological innovation, the Chief Information Security Officer (CISO) now occupies an equally pivotal position for protecting digital ecosystems. The intersection point of this power dynamic is where innovation and security converge.

In this post, we discuss how the roles of the New CISO vs CTO have changed, their roles in a post-pandemic, AI world, and the way visionary organizations are organizing cybersecurity leadership.

1. The Roles Have Evolved: CTO and New CISO in 2025

CTO in 2025: Leading With Innovation

Historically, CTOs have spearheaded innovation—creating products, managing IT infrastructure, and coordinating tech strategy with business objectives. CTOs need now:

To ensure compliance for all technologies.

To work with security teams throughout product creation.

To design robust architectures that accommodate Zero Trust concepts.

The Rise of the New CISO

Today’s CISO is no longer a specialist technical expert. The New CISO in 2025 is an executive with cross-functional impact. Roles involve:

Establishing cybersecurity policies and frameworks.

Directing threat detection and response.

Overseeing regulatory compliance (e.g., GDPR, HIPAA, ISO 27001).

Reporting cyber risks up to the board or CEO.

The line between innovation (CTO) and protection (CISO) is getting confused, leading to the New CISO vs CTO conundrum in most organizations.

2. Joint Cybersecurity Responsibilities: Overlap and Complexity

Both have distinct areas of authority, but there is a common pool of cybersecurity responsibilities where there is tension or synergy based on the structure of the organization.

CISO: Assesses security implications of new technologies prior to deployment.

Incident Response

CTO: Ensures availability of the system and recovery.

CISO: Oversees breach response, forensic analysis, and disclosure requirements.

DevSecOps

CTO: Advocates for quicker development cycles.

CISO: Incorporates security early in the pipeline.

This overlap tends to create ambiguity: Who gets the final word? The response defines the overall cybersecurity posture.

3. Regulatory and Business Pressures

Businesses in 2025 are now governed by more privacy regulations, such as GDPR updates, the U.S. Cybersecurity Maturity Model Certification (CMMC), and area-specific AI laws.

New Implications for the New CISO vs CTO Discussion

Regulatory Compliance: The New CISO will have to make sure controls are implemented.

Technical Execution: The CTO would execute tools to satisfy those controls.

Strategic Communication: Both positions need to communicate cyber risk to the board in terms familiar to non-technical leaders.

Those pressures create an urgent need to specifically define cybersecurity leadership early on.

4. Case Studies: Who Leads Cybersecurity in Practice?

Case Study 1: Financial Services Enterprise

In a global bank, the CTO was driving all digital transformation initiatives. But following a breach due to a compliance issue, the CISO was given board-level access, and there was enhanced risk management and quicker detection.

Key Insight: Cybersecurity leadership should be autonomous and in a position to veto technical decisions if necessary.

Case Study 2: SaaS Startup

Misconfiguration of a cloud bucket caused a breach, leading to investor distrust. After the breach, a CISO was brought onboard to audit and reorganize policies.

Key Insight: Innovation and protection need to be separated by startups as they grow.

Case Study 3: Healthcare Platform

In this instance, the CISO and CTO shared leading a cybersecurity governance team. With aligned KPIs and reporting lines, incidents dropped 40% year on year.

Key Insight: Coordination wins out over confrontation when roles are clarified and respected.

5. Critical Competencies of the New CISO in 2025

In order to succeed alongside the CTO, the New CISO needs to have:

Business Fluency: Knowledge of financial risk, ROI on security investment, and regulatory exposure.

Communication Skills: Capacity to report risk metrics to non-technical leaders.

Adaptability: Navigating emerging threats such as AI manipulation or deepfake social engineering.

Governance Expertise: Ensuring compliance across jurisdictions and industry verticals.

Technical Know-How: Though not a coder, the New CISO is aware of encryption, cloud security, and identity governance.

6. CTO Viewpoint: Innovation vs. Risk

Using AI/ML to enhance product.

Embracing microservices and serverless architectures.

Experimenting with blockchain for trust and transparency.

But these are risks. Left to themselves, vulnerabilities in these tools would go undetected.

7. Boardroom View: Clarity is Required for Accountability

In 2025, boards inquire:

Who is responsible for data protection?

Who is in charge of incident response?

Who is responsible for compliance in all markets?

More and more, boards insist on clarity of accountability, which drives the New CISO vs CTO debates. The direction is to make cybersecurity a collective accountability with identified control domains and escalation routes.

8. Best Practice: Collective Cybersecurity Governance

The best-performing organizations adopt co-leadership, in which:

The CTO leads innovation with a security-by-design approach.

The New CISO analyzes and optimizes the security impact of every project.

Both roles have a Chief Risk Officer, CIO, or CEO report.

Common KPIs are employed to track risk mitigation, uptime, compliance, and response time for incidents.

This allows New CISO vs CTO not to be a fight—it’s a collaboration.

9. The Role of AI and Automation in Redefining Responsibilities

AI is transforming both positions:

For the CISO: AI identifies anomalies, automates response to incidents, and assists in threat hunting.

Introduction of AI governance policies also erases role distinctions. Who sets rules on AI ethics and risk—New CISO or CTO?

In most companies, this has resulted in the formation of a Cybersecurity Governance Committee, co-chaired by both positions.

10. Organizational Designs to Close the Conflict

Model A: CISO Reports to CTO

Works in small teams

Security may be second to development

Model B: CTO and CISO Report to CIO Separately

Ensures equal influence

Needs strong CIO management

Model C: CISO Reports to CEO or Board

Creates security executive visibility and autonomy

Occurs in highly regulated industries

conclusion

Every structure has implications for speed, accountability, and resilience.

As we continue into an increasingly hyper-connected, AI-centric digital future, the line between security and innovation is increasingly indistinct. New CISO vs CTO is more than a matter of nomenclature—it’s an indicator of shifting priorities for leadership and organizational requirements.

The CTO remains the innovation beacon, who is charged with driving growth through technology. The New CISO, however, has emerged as the custodian of trust, whose responsibility is to safeguard information, people, and systems against increasingly technical cyber attacks.

In 2025 and beyond, the most secure and resilient companies will be the ones that foster cooperation between these two important roles. Instead of remaining in silos or fighting it out for power, the New CISO and CTO must collaborate as strategic partners. Shared accountability, well-defined roles, and respect for each other will drive stronger cybersecurity positions, faster innovation, and improved compliance.
