You do not need to begin your career as a hacker, have a computer science degree or already know every security tool to work in cyber security. People enter the profession from IT support, networking, software development, audit, risk, the armed forces, education and completely different careers.
The most reliable route is to build a strong technical foundation, understand the main cyber security roles, gain practical experience and choose training or certifications that match the type of work you want to do.
Is cyber security a single career?
No. Cyber security covers many different specialisms. Some are highly technical, while others concentrate more on risk, governance, audit, management or communication.
Common career areas include:
- Security Operations Centre (SOC) analysis
- incident response
- threat hunting
- penetration testing and ethical hacking
- security engineering
- identity and access management
- cloud security
- security architecture
- digital forensics
- governance, risk and compliance
- IT audit and assurance
- security management
The UK Cyber Security Council recognises a range of professional specialisms, which is a useful reminder that there is no single cyber security career ladder.
Can you start a cyber security career with no experience?
Yes, but it helps to separate no cyber security experience from no IT knowledge at all.
If you already understand computers, networks, operating systems or cloud services, you may be able to move into security relatively quickly. If technology itself is new to you, spend time building those foundations first.
Cyber security makes much more sense when you understand the systems you are trying to protect.
Step 1: understand how computers and networks work
Before specialising, develop confidence with the fundamentals.
Useful areas include:
- Windows and basic Linux administration
- IP addresses and subnets
- DNS
- TCP and UDP
- common ports and protocols
- routers, switches and firewalls
- user accounts and permissions
- cloud services
- basic scripting
You do not need to be an expert in all of these before starting security training, but gaps in basic networking and operating-system knowledge can make later topics unnecessarily difficult.
Should you learn networking before cyber security?
For most technical security roles, yes.
Many attacks involve network connections, DNS requests, suspicious traffic, exposed services or remote access. Analysts and penetration testers therefore need to recognise what normal network activity looks like before they can reliably identify abnormal behaviour.
If networking is new to you, certifications such as CompTIA Network+ or Cisco CCNA can provide a structured foundation. ExperTrain's existing comparison of CCNA vs CompTIA Network+ explains the difference between these routes.
Step 2: learn the security fundamentals
Once your IT foundation is developing, learn the core security concepts that appear across almost every role.
These include:
- threats and vulnerabilities
- malware and ransomware
- phishing and social engineering
- authentication and multi-factor authentication
- identity and access management
- encryption and public key infrastructure
- network security
- vulnerability management
- incident response
- risk management
- backups and resilience
CompTIA Security+ is a common vendor-neutral foundation for people moving into technical cyber security roles. ExperTrain offers instructor-led CompTIA Security+ training.
Which certification should a beginner take?
There is no universal answer, but two common starting points are ISC2 Certified in Cybersecurity (CC) and CompTIA Security+.
ISC2 CC is explicitly designed as an entry-level certification and does not require previous work experience.
Security+ is particularly useful for people who already have some IT or networking knowledge and want a broad technical security foundation.
Our Cyber Security Certification Guide compares beginner, analyst, penetration-testing, cloud, audit and management pathways.
Step 3: choose a direction
You do not need to decide your entire career on day one, but choosing an initial direction helps you avoid collecting unrelated certifications.
If you like investigation and monitoring
Look at SOC analyst, cyber security analyst and incident-response roles.
Our What Does a SOC Analyst Do? article explains the day-to-day work, including alert triage, SIEM, EDR/XDR and threat hunting.
If you like testing systems
Look at penetration testing, vulnerability assessment and ethical hacking.
Start with our What Is Ethical Hacking? guide. Relevant certification routes include CompTIA PenTest+ and EC-Council CEH after suitable foundations.
If you like cloud technology
Build strong Azure, AWS or other cloud-platform knowledge alongside security. Cloud security is difficult to do well if you understand security but not the platform being protected.
If you prefer risk, governance or audit
Cyber security is not only about technical operations. ISACA pathways such as CISA and CISM are relevant to experienced audit, governance and management professionals, while risk-focused roles may lead towards CRISC.
Step 4: get practical experience
Certifications are useful, but employers also want evidence that you can apply what you know.
Practical experience can come from:
- an existing IT support or networking job
- security responsibilities within your current role
- authorised training labs
- home labs using systems you own
- capture-the-flag exercises designed for learning
- cloud sandboxes
- volunteering for legitimate security-related projects
Only practise security testing on systems you own or environments where testing is explicitly authorised.
Is help desk experience useful for cyber security?
Very much so.
Help-desk and desktop-support roles build skills that transfer directly into security, including troubleshooting, user accounts, permissions, Windows, networking, remote support and communication.
Someone who understands how users and systems normally behave can often investigate security incidents more effectively than somebody who has only studied security theory.
Can you move from networking into cyber security?
Yes. Networking is one of the strongest technical foundations for a security career.
Network professionals already understand traffic flows, firewalls, routing, switching, DNS and connectivity. Adding security analysis, identity, threat detection and incident response can create a natural route into security engineering or SOC work.
Can you move from software development into cyber security?
Yes. Developers can move into application security, DevSecOps, cloud security, security engineering and penetration testing.
Understanding how applications are designed and deployed is particularly valuable when assessing vulnerabilities or integrating security earlier into the software-development lifecycle.
Do you need a degree for cyber security?
No, not for every role.
Some employers prefer or require a degree, particularly for graduate programmes, research roles or certain specialist positions. Others place greater emphasis on experience, certifications, technical skills and evidence of continuous learning.
If you already have professional experience, returning to university is not automatically necessary. Choose the learning route that best fills your actual skills gaps.
Do you need to know programming?
Not to begin every cyber security role.
Programming is more important in areas such as application security, security automation, malware analysis and some penetration-testing roles. For many beginners, basic scripting is enough initially.
PowerShell, Python and shell scripting can become useful because they help automate repetitive tasks and analyse data.
What is the best first cyber security job?
There is no single best role, but common entry points include:
- junior SOC analyst
- junior cyber security analyst
- IT support role with security responsibilities
- network or systems administrator with security duties
- identity and access administrator
- governance, risk or compliance analyst
Direct entry into penetration testing is possible, but it is often easier after building strong networking, operating-system and security foundations.
What certifications can help after Security+?
Your next certification should match your direction.
Defensive security: CompTIA CySA+ or Microsoft SC-200.
Penetration testing: CompTIA PenTest+ or EC-Council CEH.
Experienced broad security professional: ISC2 CISSP.
Cloud security: cloud-platform knowledge followed by qualifications such as ISC2 CCSP when you have appropriate experience.
Security management: ISACA CISM.
How long does it take to start a cyber security career?
It depends heavily on your starting point.
An experienced network engineer or system administrator may be able to transition relatively quickly because much of the underlying knowledge is already in place. Someone completely new to IT may need longer to build a foundation before specialising.
Avoid measuring progress only by certificates. Being able to explain what happened in an incident, interpret evidence and solve real problems matters more than how quickly you collected exam passes.
How do you make your CV stronger?
Connect your experience to security rather than listing certificates without context.
Useful evidence can include:
- accounts and permissions you managed
- incidents you investigated
- patching or vulnerability work
- networking responsibilities
- cloud services you administered
- security improvements you implemented
- training labs or projects you can explain clearly
Do not exaggerate. Being able to discuss a small real project confidently is better than claiming expertise you cannot demonstrate in an interview.

Frequently asked questions
Is cyber security hard to get into?
It can be competitive, particularly for people applying directly to security roles without IT experience. Building networking and systems knowledge and demonstrating practical ability makes the transition easier.
Is Security+ enough to get a job?
It can strengthen an application, but no certification guarantees employment. Combine it with practical knowledge, relevant experience and evidence that you can apply the concepts.
Can I start cyber security in my 30s, 40s or 50s?
Yes. Career changers can bring valuable experience in management, communication, risk, audit, customer service and other industries. The key is identifying the technical knowledge needed for the role you want.
Should I learn ethical hacking first?
Usually not if you are completely new to IT. Networking, operating systems and broad security fundamentals provide a stronger foundation.
What is the best cyber security role for beginners?
SOC analysis is a common entry route for technically minded learners, while governance, risk and compliance can suit people with stronger business, audit or regulatory backgrounds.
