Become a CISO — Career Roadmap by Dr. Erdal Ozkaya

Career Roadmap — Updated 2026

How to Become a CISO

The honest, unfiltered roadmap from security professional to Chief Information Security Officer — from someone who has done it and coached hundreds of others through the same journey.

A word from Dr. Erdal Ozkaya: “I get asked this question more than any other — at every conference, in every mentoring session, from every aspiring security leader who reaches out on LinkedIn. So let me give you the real answer, not the sanitised version you’ll find on most career advice websites.”

What a CISO Actually Does

Before you plan the journey, understand the destination. The CISO role in 2026 is fundamentally a business leadership role that requires deep technical credibility. You are not running a firewall — you are managing enterprise risk, advising the board, building security culture, and translating threat intelligence into business decisions. The best CISOs I know spend more time in the boardroom than the server room.

The Three-Phase Journey

Phase 1 — Years 1 to 5

Build Unshakeable Technical Foundations

This phase is about earning your right to be in the room. You need to understand how attacks work before you can defend against them. Get your hands dirty in incident response, penetration testing, network security, and cloud security operations.

  • Earn CompTIA Security+, then CEH — understand how attackers think
  • Work in a SOC, on a red team, or in an IR role — real experience beats certifications
  • Develop deep expertise in at least one domain: cloud security, OT/ICS, application security, or identity
  • Start building your professional network — attend local ISACA or (ISC)² chapter meetings
  • Begin writing: a blog, LinkedIn articles, or contributing to open-source security projects
Real talk: Most people rush through this phase. Don’t. The CISOs who struggle in the boardroom are often those who moved into management before they truly understood how attacks work at a technical level. Your technical depth is your credibility.
Phase 2 — Years 5 to 10

Develop Business Acumen and Leadership Skills

This is the phase that separates future CISOs from perpetual engineers. You need to start learning how businesses actually work — how decisions are made, how risk is communicated to non-technical stakeholders, and how budgets are justified.

  • Move into security management: Security Manager, Security Architect, or Deputy CISO roles
  • Earn CISSP, CISM, and CRISC — these signal leadership and risk management maturity
  • Take an MBA module or executive education course in business strategy or finance
  • Learn to present to executives: no technical jargon, pure business risk language
  • Build a track record of managing teams, vendors, and security programmes end-to-end
  • Start mentoring junior security professionals — leadership is practised, not learned in a classroom
From my own experience: The moment I started presenting cyber risk in terms of financial impact, regulatory exposure, and reputational consequence — rather than CVE scores and patch counts — is when boards started genuinely listening. That shift takes deliberate practice.
Phase 3 — Years 10 and beyond

Build Executive Presence and Strategic Vision

By this phase, your technical credibility is established. Now it is about becoming someone a board trusts to protect the organisation’s future. This requires a different kind of development.

  • Pursue CCISO (Certified CISO) — the only certification designed specifically for the CISO role
  • Develop a personal thought leadership platform: speaking, writing, and professional community involvement
  • Seek board-level exposure: present to boards, sit on advisory boards, understand director obligations
  • Build cross-functional relationships: legal, finance, HR, and operations leaders are your allies
  • Stay current on AI security, quantum-safe cryptography, and emerging regulatory frameworks (EU AI Act, NIS2, DORA)
What most guides miss: The CISO seat is rarely filled by the most technically brilliant person in the room. It goes to the person the CEO trusts to be honest about risk — including the risks that are inconvenient to hear. Build that reputation early.

Certifications That Actually Matter

Not all certifications carry equal weight. Here is how I rank them for someone on the CISO path:

Must Have

CISSP

The baseline credential for senior security roles. Without it, you will be filtered out of shortlists for many CISO positions.

Must Have

CISM

Management-focused and highly regarded by boards. Signals that you understand governance, not just technology.

Strongly Recommended

CRISC

Risk management fluency is non-negotiable for CISOs. CRISC demonstrates you can quantify and communicate risk.

Strongly Recommended

CEH

Builds the attacker mindset that makes your defensive strategy credible. Essential in Phases 1 and 2.

Executive Level

CCISO

The only certification designed specifically for CISOs. Covers strategy, governance, finance, and programme management.

Executive Level

CGEIT

Demonstrates IT governance expertise — increasingly expected for CISOs reporting to boards.

Mistakes That Will Derail Your Journey

I have mentored hundreds of aspiring CISOs. These are the patterns I see repeatedly in those who stall:

  • Staying in the technical lane too long. Depth is essential early, but you must deliberately develop business communication and leadership skills from Year 3 onwards — not Year 10.
  • Collecting certifications instead of experience. Ten certifications and no track record of leading a security programme will not get you the CISO seat. Experience in the role matters more.
  • Neglecting your personal brand. In 2026, CISOs are expected to be visible and credible externally. Start speaking, writing, and sharing your thinking now — not when you are ready to apply for CISO roles.
  • Ignoring the business side of security. If you cannot explain a security investment in terms of risk reduction, regulatory exposure reduction, or revenue protection — you will not get the budget, and you will not keep the job.
  • Not building a mentor network. The CISO community is generous. Join the Global CISO Forum, ISACA, or local security leadership groups. The peers you build relationships with will be the ones recommending you for opportunities.
