How to Become a Penetration Tester
Attacks on businesses happen every day. However, penetration testers prevent them. They use their hacking skills to find weak spots before criminals do. Right now, there aren’t enough of them, even though demand for penetration testers in the UK is super high.
If you enjoy working with computers and are good at spotting problems others miss, consider becoming a penetration tester. You don’t need to have it all figured out right now, because in this guide we cover the skills, qualifications, experience you need to get started, what the job entails and why businesses value this role so highly.
What Qualifications Do You Need to Become a Penetration Tester?
Professional certification route
If you want to work in pen testing but don’t have a computer-related degree, you’ll need a mix of work experience and industry certifications. This path typically begins with an entry-level role in systems administration, IT development, or IT support, and you work your way up as you build practical, hands-on knowledge of IT infrastructure and networks.

Do I need a degree to become a penetration tester?
No, a degree is not essential, but it can help you get started faster. Many successful penetration testers move into the role from IT support, systems administration or software development, building technical expertise through practical hands-on experience. Employers mostly care about demonstratable, tested skills against real systems, so a strong certification and a portfolio of practical work can carry as much weight as a formal degree.
Penetration testers are also known as ethical hackers or white hat hackers because they use their hacking skills for good.
What are the skills required of a penetration tester?
Having certifications is a good thing but employers look for a certain skill set that’s the perfect blend of technical expertise and soft skills. It’s important that you have a combination of both skills.
Hard skills
Understanding of network security and IT infrastructure
You can’t test what you don’t understand
Practical experience with tools
Understanding tools like Kali Linux, along with automated tools for scanning and manual techniques for the more nuanced testing automated tools can miss
Knowledge of relevant programming languages
Python, Bash and Scripting are common
Understanding of software development
Knowing how applications are built can also help in taking them apart
Reverse engineering skills
Soft skills
Communication skills (spoken and written)
You’ll need to explain complex information to non-technical stakeholders and produce and present detailed reports.
Analytical skills
Spotting patterns and weaknesses across complex systems
Attention to detail
A misconfiguration can allow attackers easy access
Problem solving skills
The ability to think strategically
Being able to anticipate how hackers might turn a smaller weakness into a serious breach
What Does a Penetration Tester Do?
Using their knowledge of hacking methodologies, computer systems, web applications and software, penetration testers test the cyber defences of businesses to check they can withstand real-world threats. With a mix of automated tools and manual techniques, these security experts simulate attacks, identify vulnerabilities and recommend remediation before attackers can exploit them.
A big part of the job is risk: testers assess an organisation’s exposure to potential threats, feed findings into wider risk management processes and help businesses prioritise which weaknesses to fix first. This might mean testing everything from antivirus software configuration to how staff respond to social engineering attempts, since human error remains one of the most common ways attackers gain access.

Typical Duties for a Penetration Tester
Popular Career Pathways for Penetration Testers
Once you’ve gained 3-5 years of experience as a professional penetration tester, you’ll be able to progress to the role of senior penetration tester. From there, you could move into a lead cyber security specialist, security consultant, or security architect role. Alternatively, you might prefer self-employment or consultancy work, offering services directly to businesses that need support assessing their security posture.
Is penetration testing a good career?
Yes, penetration testing offers strong long-term career prospects due to growing demand across almost every sector. As businesses handle more sensitive data, from financial data to customer records, there’s greater pressure to demonstrate compliance so people can have peace of mind about their security. Penetration testers who build a track record of clear reporting and up-to-date technical skills usually progress into senior testing, security architecture or consultancy roles.
IT security is big news, and UK businesses are increasingly investing in penetration testing to protect valuable data from new threats. So if you’re tech-savvy with a desire to learn, why not join the fight against cyber criminals by signing up to one of our cyber security courses?
