What is an ethical hacker? Roles, skills and career paths

Cyber criminals are always looking for new opportunities to target information, data and systems. As hacking tactics evolve, organisations must keep up to date with the latest threats, understand where they’re at risk and put provisions in place to defend their businesses, making penetration testing a crucial part of any security team’s capabilities.

Ethical hackers play a major role in this. These are cyber security experts who identify risks and vulnerabilities within system configurations by employing similar techniques to criminals. However, they operate in a more regulated environment and within strict legal guidelines. The overall purpose of employing an ethical hacker is to improve the resilience of an organisation’s defence against cyber crime.

What is an ethical hacker?

Ethical hackers are professionals who use their expertise to perform proactive security assessments. Organisations are increasingly facing the risk of data breaches, where unauthorised third parties gain access to sensitive company information. 

Conducting an ethical hack involves copying the same strategies of these malicious attackers. Ethical hackers are given wide latitude by hiring companies in terms of what they’re allowed to do, but instead of exploiting vulnerabilities, they use their expertise to document weaknesses and areas for improvement, also known as threat intelligence.

Ethical hacking means wearing the ‘white hat’ and contributing to cyber security frameworks in a proactive manner before a criminal, ‘black hat’ hacker has the chance to exploit vulnerabilities. These frameworks are a set of documents made up of guidelines, standards and best practices that are used to inform cyber security risk management.

Ethical hacking vs black hat hacking

The term hacking evokes ideas of illegal activity, but white hats have no malicious intent. Ethical hackers are employed by organisations with the express purpose of revealing security vulnerabilities before any black hat hacking can take place. The best way to effectively carry out security testing is to use the same techniques as those looking to breach defences for their own criminal gains, and this is where white hat hackers are invaluable.

While many ethical hackers are employed directly by businesses, some hackers may operate on their own, looking to claim bug bounties or identify weaknesses without authorisation. These individuals can fall into a legal and ethical grey area, so it’s important to be aware of the differences.

The following table summarises how the different types of hacker operate:

	White hat hacking	Grey hat hacking	Black hat hacking
Intent	Legitimate, authorised security testing	Mixed, may operate without explicit consent but without malicious intent	Malicious, aims to exploit or damage systems
Authorisation	Always authorised by system owners	Often unauthorised or unclear	Never authorised
Legal status	Legal and ethical	Legally ambiguous or potentially unlawful	Illegal
Objective	Identify and fix vulnerabilities	Discover vulnerabilities, may disclose to owners or publicly	Steal, disrupt or damage data and systems
Outcome for organisations	Improves overall security posture	Can prompt fixes but carries legal and reputational risk	Causes financial loss, disruption or data breaches
Common roles	Ethical hacker, penetration tester, security consultant	Independent researchers, some bug bounty participants	Cybercriminals, threat actors

What does an ethical hacker do?

An ethical hacker helps organisations strengthen their cyber security by proactively identifying weaknesses before malicious attackers can exploit them. Their role combines hands-on technical testing with analysis and reporting, allowing businesses to understand where their defences are most vulnerable and how to improve them.

A skilled ethical hacker will employ most of the same tactics as any unauthorised third party. This means organisations can see exactly how attackers could try to enter their systems, leading to a clearer understanding of how to prevent it from happening.

Common day-to-day tasks include:

• Planning and executing authorised security tests: Defining test scope and carrying out controlled attacks to evaluate how resilient systems, applications and networks are to real threats.
• Replicating attacker behaviour: Using current attacker techniques to show how threats could bypass controls, helping organisations understand realistic attack paths.
• Assessing and prioritising security weaknesses: Analysing identified vulnerabilities to determine their severity, likelihood of exploitation and potential business impact.
• Communicating findings to stakeholders: Presenting results clearly to technical teams and decision makers so risks are understood at the appropriate level.
• Supporting remediation priorities: Helping organisations determine which vulnerabilities to address first based on risk, effort and potential impact.
• Maintaining current technical expertise: Continuously updating knowledge of tools, exploits and threat trends to keep testing relevant and effective.

How do you become an ethical hacker?

Unlike many other cyber security career paths, there isn’t a standard route into ethical hacking. While some professionals have an academic background in cyber security, many are self-taught due to an interest in the field.

However, companies generally set bespoke requirements for positions depending on the specific needs, threats or vulnerabilities they might be looking to work on, so ticking off the following steps can set a good foundation for an ethical hacking career.

Step one: Education

Formal training is not mandatory, but it can help demonstrate foundational knowledge and commitment. Potential qualifications and educational backgrounds include:

• Cyber security or computing degrees: Provide grounding in networks, operating systems and security principles.
• Certifications: Options such as CEH, Security+ or Network+ help validate baseline knowledge.
• Self-directed learning: Online courses and labs support practical understanding alongside theory.
  

Step two: Skills

Ethical hacking requires hands-on technical capability as well as analytical thinking. Being able to demonstrate the below skills can be useful when applying for jobs.

• Networking fundamentals
• Linux and Windows operating systems
• Scripting and basic programming
• Web application security
• Vulnerability identification and exploitation
• Penetration testing tools and frameworks
• Cloud and infrastructure security basics
• Analytical and problem-solving skills
  

Step three: Experience

Practical experience is often the deciding factor for employers, but this does not necessarily have to be formal work within organisations. Potential experience to highlight may include:

• Labs and platforms: Using environments such as Hack The Box or TryHackMe to build real skills.
• Bug bounty participation: Gaining exposure to real-world vulnerabilities within legal frameworks.
• Junior security roles: Building experience in adjacent cyber security positions.
  

Common entry-level roles for ethical hackers include:

• Junior penetration tester
• Security analyst
• SOC analyst
• Cyber security technician
• Vulnerability management analyst

How do you become a certified ethical hacker?

As ethical hacking becomes more mainstream, there are now a number of certifications that prove a penetration tester’s credentials in the field. Among the most relevant ethical hacking courses are:

• EC Council: Certified Ethical Hacking Certification
• Offensive Security Certified Professional (OSCP) Certification
• CompTIA Cybersecurity Analyst (CySA+)
• Cisco’s CCNA Security
• WEB-300: Advanced Web Attacks and Exploitation (OSWE)
• SANS GIAC

Passing one of these industry certifications for ethical hackers will validate how much a professional knows about specific areas of the field. For example, a Certified Ethical Hacker (CEH) certification shows that a professional has a mastery of network security and attack technologies. Conversely, a certification such as the CompTIA Cybersecurity Analyst (CySA+) demonstrates proficiency in using behavioural analytics to solidify network security.

Key sectors where ethical hackers are in demand

Demand for ethical hackers remains strong and will only continue to grow in the digital age. Most organisations now rely on technology and store a lot of data, making them potential targets for a cyber attack, but specific industries can be particularly susceptible.

• Finance: Banks, insurance companies and other financial institutions are increasingly in need of ethical hackers to secure their databases and systems from cybercriminals, because of the large amounts of personal and financial customer data they have on record.
• Technology: Software development companies, cloud computing/SaaS providers and IT consulting firms hold highly confidential data and are often early adopters of new technologies, which can make them vulnerable to attacks, so ethical hackers are crucial to preventing breaches.
• Healthcare: Assessing and strengthening the cyber security infrastructure in healthcare legacy systems is important to protect patient information and prevent unauthorised access to medical databases, which can be easily monetised or used for identity theft.
• Government: Public sector organisations manage large volumes of sensitive citizen data and operate systems essential to national security. This makes them attractive targets for cyber attacks, particularly from hostile actors seeking disruption, espionage or data theft.
• Critical infrastructure: Energy, transport and utilities sectors rely on operational technology and legacy systems that are increasingly connected to digital networks. These environments can be especially vulnerable to cyber attacks that risk service disruption, safety issues and economic damage.
