What to Study to Work in Cybersecurity: A Guide to Training and Career Opportunities

Discover how to find your job in cybersecurity

Cybersecurity has become one of the areas with the highest demand for talent in Spain and the rest of Europe, but those looking to enter this sector often ask themselves the same question: what exactly should I study? The short answer is that there isn't just one path. There's a recommended foundation, technical certifications that the industry particularly values, and, increasingly, postgraduate specialization programs that condense into a few months the skills that were previously acquired through years of scattered experience. In this guide, we review the existing professional profiles, the appropriate training at each stage, and the real career opportunities in the sector.

Why study cybersecurity right now?

The decision to train in cybersecurity is not just a technological trend: labor market data confirms this. According to the measure Hacker Talent, Driven by the Spanish Government within the framework of the Digital Spain 2026 Agenda and managed by INCIBE, the sector already employed more than 150,000 professionals in 2023 and generated a turnover of €2 billion. However, demand remains unmet: in 2024, vacancies exceeded 83,000, and projections indicate that at least 99,600 specialists will be needed by 2025, with annual growth of between 20% and 25%.

The one himself INCIBE, In its cybersecurity talent assessment report, [company name] places the sector's workforce in Spain at around 122,284 professionals, with an estimated gap of more than 24,000 unfilled positions.

Professional profiles in cybersecurity: the map of specializations

Before deciding what to study, it's important to know that “cybersecurity” isn't a single profession, but rather a collection of distinct specializations. The most common reference used by the industry to categorize them is the ENISA's European Cybersecurity Skills Framework (ECSF), The European Union's cybersecurity agency defines twelve key professional profiles with their associated tasks, skills, and knowledge. Understanding this framework helps you determine which specialization to pursue in your training. If you'd like to do an initial self-assessment to see which profile best suits you, you can also read [here/online/etc.]. Cybersecurity: Where do you fit in?

Offensive security: the profile the industry calls “Red Team”

These are the professionals who think like an attacker to find vulnerabilities before an actual cybercriminal does. This is where the pentester The penetration testing expert, the ethical hacking specialist, and the threat researcher are among the profiles with the highest short-term salary potential in the sector.

Defensive security: the “Blue Team” profile”

They are the ones who monitor, detect, and respond to incidents once they have occurred, or prevent them by strengthening systems. The analyst at a Security Operations Center (SOC) and the Cyber Incident Responder These are the most in-demand roles in this group. If you're interested in this profile, in Monitoring and response to incidents We delve into how a SOC works on a day-to-day basis.

Governance, risk and management

As they gain experience, many professionals evolve into management positions: compliance officer, risk manager, or, at the highest level, Chief Information Security Officer (CISO). This is the natural path for those who want to combine technical knowledge with team and business leadership skills, something we develop at The role of the CISO in digital transformation.

What educational background do you need to get started?

There is no single “required” degree to enter the field of cybersecurity. The most common path remains a degree in Computer Engineering, Telecommunications, Mathematics, or related disciplines, which provides the foundation in networks, systems, and programming upon which specialization is built. However, the sector is also one of the most open to career transitions: professionals with experience in auditing, digital law, systems administration, or even without prior technical training are entering the sector through intensive specialization programs, provided they combine theoretical training with real-world practice in simulated environments.

The recommended educational path: from degree to specialization

University or basic technical training

A university degree or advanced vocational training qualification in the ICT field provides the fundamentals of networks, operating systems, and programming that are later applied to security. It is not a strict requirement, but it does facilitate the subsequent learning curve.

Technical certifications recognized by the sector

Beyond academic qualifications, the market particularly values specific technical certifications such as OSCP (offensive security), CEH (ethical hacking) or CISM (information security management). These are credentials that many companies explicitly request in their job offers and that usually complement, not replace, postgraduate training.

A specialized master's degree with a job guarantee

For those who want to accelerate their progress and enter the sector with a solid and accredited foundation, a specialized master's degree is currently the most direct route. Master's Degree in Cybersecurity Management, Ethical Hacking and Offensive Security from EIP It is designed precisely with this dual perspective: it combines an offensive security module (ethical hacking, cryptography, cyber intelligence, advanced security testing in OT/IoT environments) with a defensive security module that includes risk management, security architecture, regulations, and a specific module on managing and responding to cyber incidents (Blue Team), in addition to a final master's project. The program is completed online at your own pace, with practical experience in real-world labs and simulated environments, and features an active job placement service with more than 50 companies in the technology and cybersecurity sector.

Essential technical and soft skills

Regardless of the profile you are aiming for, there is a core set of skills that the sector requires across the board:

Type of skillExamples
TechniquesNetworks and protocols, operating systems (especially Linux), scripting (Python, Bash), cloud environments
AnalyticsCritical thinking, forensic analysis, ability to detect anomalous patterns
RegulationsKnowledge of frameworks such as ENS, NIS2 or GDPR
Cross-cuttingClear communication with non-technical teams, ability to work under pressure, continuous learning

Constant updating is perhaps the most crucial skill: threats evolve every few months and anyone who trains in cybersecurity assumes that they will continue training throughout their career.

Career opportunities and indicative salaries

Salaries vary depending on specialization, experience, and region, but they serve as a general guideline. According to the 2026 Remuneration Study cited on the official website of the EIP Master's in Cybersecurity, these are some salary ranges for junior profiles:

ProfileJunior salary range
SOC Analyst Level 1€22,000 – €30,000
Pentester Junior / Ethical Hacker Junior€25,000 – €35,000
Junior Cloud Security Analyst€30,000 – €40,000

These figures correspond to entry-level positions; progression to managerial or CISO roles typically translates into significant increases as experience is gained and knowledge is certified. Companies such as Deloitte, Accenture, Indra, and Telefónica are among those actively collaborating in the recruitment of cybersecurity talent; you can consult the complete list at EIP partner companies.
