Looking to accelerate your IT career but not sure where to start? This guide highlights the fastest-growing skill areas, the roles driving demand, and how you can begin your journey through NILC’s expert-led training options.
According to research by CompTIA, the organisation behind globally recognised IT certifications, three key technical domains are driving employer demand today: cybersecurity, data, and artificial intelligence (AI).
For professionals based in Wales and across the UK, this is good news. Targeted training and certification in these areas can open doors to roles that are expanding rapidly, offer clear progression, and align with funding schemes such as PLA, ReAct+ and the Flexible Skills Programme. This article summarises the most in-demand roles, explains why they matter, and shows how you can access the right training via NILC.
Why Cybersecurity, Data and AI Are Top Priorities
CompTIA’s State of the Tech Workforce 2025 report shows that even amid a challenging economic backdrop, the tech workforce grew by about 1.2% in 2024. Growth has been concentrated in core pillars: data, cybersecurity, infrastructure and tech-enablement roles.
In its State of Cybersecurity 2025 report, CompTIA highlights that cybersecurity has become a business imperative, not just a technical function. Demand for skilled professionals remains difficult to meet: “Even in a tight labour market, demand for cybersecurity skills is difficult to solve.”
On the AI front, CompTIA’s job-posting data shows that roles requiring AI skills are rising sharply. Employer job postings mentioning AI grew significantly year-on-year.
The message is clear: organisations are investing in security, data and AI capabilities, and they need skilled professionals to deliver them. That means strong opportunities for those who prepare now.
Before exploring specific career paths, it helps to see how these trends translate into practical opportunities for learners and professionals.
In-Demand Roles You Should Know About
Cyber-Security Analyst / Engineer
As cyber-threats evolve – from ransomware to AI-generated attacks – organisations need professionals who can assess risk, manage incidents and protect hybrid environments. According to CompTIA’s Cyberseek tool, there were over 514,000 cybersecurity-related job postings between May 2024 and April 2025. The urgency is underscored by recent events such as the August 2025 cyberattack on Jaguar Land Rover, which halted production for weeks and is estimated to have cost the UK economy £1.9 billion – making it the most financially damaging cyber incident in British history.
Typical responsibilities:
- Monitoring networks, endpoints and cloud services for threats
- Analysing vulnerabilities and implementing controls
- Responding to incidents and conducting investigations
- Ensuring compliance with governance frameworks (e.g. GDPR, ISO 27001)
Why it matters: This role sits at the intersection of technology and business risk. Professionals who combine technical ability with governance and compliance awareness are especially valuable.
Recommended training at NILC:
- CompTIA Security+ certification – vendor-neutral and focused on governance, hybrid environments and threat management.
- Progression to CySA+, PenTest+ and cloud-security courses (Microsoft Azure Security, AWS Security) once the basics are mastered.
Data Professional (Data Analyst / Engineer)
Data is now the backbone of decision-making in most organisations. From analytics dashboards to machine-learning models, businesses need people who can turn raw data into insight. CompTIA reports that 46% of firms place “far more emphasis on data today compared to two years ago.”
Key responsibilities:
- Collecting, cleaning and transforming data for analysis
- Building dashboards (Power BI, Tableau) to inform business decisions

- CompTIA DataX – a new certification reflecting the surge in data roles.
Cloud/AI Engineer
Cloud and AI are now deeply connected. Organisations are moving workloads to the cloud and embedding AI within business processes. CompTIA data shows job adverts mentioning AI skills rose by roughly 94% between August 2024 and August 2025.
Typical responsibilities:
- Designing and implementing cloud architectures (Azure, AWS, Google Cloud)
- Developing or integrating AI-driven applications
- Ensuring AI systems are secure, reliable and business-aligned
Why it matters: This role combines innovation with infrastructure. It’s ideal for learners seeking forward-looking, high-impact roles.
Recommended training at NILC:
