Modern organizations have increased the complexity of their IT infrastructures. And malicious actors continuously attempt to take advantage of this complexity to find vulnerabilities in systems, networks, and applications.

In this ever-evolving field of information security, a penetration testing career is something that remains in demand. 

Penetration testing (also known as pentesting) is an offensive cybersecurity approach that identifies weaknesses and vulnerabilities before malicious actors do. The goal of a pentest is to emulate all possible ways an attacker could penetrate a given computer system, find security gaps and vulnerabilities, and produce findings that will steer further actions for remediation. This ultimately helps organizations improve their security posture and proactively protect against cyber attacks and data breaches. 

It is important to understand what a penetration testing career entails before you begin your training and learning journey so you can take the right steps towards this rewarding career.

Why should you pursue a career in penetration testing

Penetration testing is a growing field that offers promising career opportunities for ambitious cybersecurity practitioners. 

The average base salary of a penetration tester in 2022 is reported to be $88,206 per year. 

A penetration testing career is rewarding in the monetary sense but also in terms of job satisfaction and career progression. It’s a fast-paced and challenging career path, making it appealing to many trying to break into the industry. Pentesters need to be creative, innovate in their techniques, and constantly stay up-to-date on recent developments and the threat landscape, making it an engaging career path. 


Penetration tester tasks and responsibilities

The day-to-day tasks and responsibilities for pentesters depend on the project, organization, and scope but the usual workflow includes planning and launching assessments, writing reports, debriefing clients, and providing recommendations for security improvements. You may work at a customer site or work from your own home.

Some of the specific tasks penetration testers do as part of their assessments are:

  • Testing applications, cloud infrastructures, and network devices
  • Researching and executing different types of attacks
  • Automating common scanning and testing techniques
  • Performing code reviews
  • Performing social engineering attacks
  • Documenting security and compliance violations and issues
  • Writing technical reports
  • Suggesting remediation activities
  • Communicating findings to stakeholders and executive leadership
  • Validating new security controls and processes with further testing 


Top skills needed to become penetration tester

Pentesting can be a competitive field and while there is plenty of job openings, it can be challenging to get the initial entry-level role. Aspiring pentesters need to maintain and demonstrate their skills in order to stand out from the crowd. 

The foundational knowledge required to become a pentester is commonly developed in network and system administration, software development, and other IT roles. 

A solid understanding of operating systems and systems architecture is one of the key areas of a penetration tester’s skill set. Other valuable skills needed to become a successful pentester include: 

1. Networking 

Knowledge of networking models, computer network architecture and networking protocols is a must for any aspiring pentester. This includes the knowledge of link-layer protocols (Ethernet/ARP, VLANs, and WiFi), network-layer protocols (IPv4, IPv6, and ICMP), transport-layer protocols (TCP and UDP), and application-layer protocols (DNS, HTTP, HTTPS, DHCP, LDAP, FTP, SMTP, SSH, and others). 

2. Knowledge of exploits and vulnerabilities 

While pentesters employ a wide range of automated tools and vulnerability scanners to uncover security issues, it’s important to have solid knowledge that goes beyond automated approaches. And while exploit development is not a requirement for pentesting, some basic knowledge on how to adapt certain exploits to work for a given environment is a great addition to the skill set. 

3. Scripting and writing code 

It’s well known that pen testers with a background in programming and development have an easier time getting their start. Code can introduce significant vulnerabilities in systems and networks, so it’s good knowing where and what to look for in code analysis. There are also a few languages that can help pen testers in exploit development and for scripting their tests. At the start of the career, it’s good to focus on learning tools for code analysis and have basic competency in Python, Bash, Java, JavaScript, C, C++, and PowerShell.

4. Soft skills

Perhaps equally important as technical knowledge and skills, are the pen tester’s mindset and soft skills. The nature of pentesting work requires professionals to possess certain qualities and soft skills to be successful. 

Pentesting is all about being one step ahead of bad actors which means that pen testers must constantly learn new techniques and exploits, and gain and practice new skills to be effective in their roles. 

In order to effectively handle operating in unknown environments, pentesters need to have a high tolerance for uncertainty. We encourage the Try Harder mindset for a reason! 

Furthermore, pentesting requires excellent problem-solving skills, determination to not give up, creativity, and the ability to think on the spot. Good communication skills to explain findings in a language understandable to non-technical individuals are also crucial. And next to good communication skills is report writing. 

When working with clients, pen testers need to showcase their understanding of business objectives and key concerns, empathize with developers and IT staff, know how to set the scope and negotiate with clients and maintain a positive relationship with them over time.

Penetration testing career path 

There are several ways aspiring pen testers can into the field. Usual career paths start with a background in security administration, network administration, network engineering, system administrator, or programming. However, penetration testers can follow unusual paths and come to the field from various technical and non-technical backgrounds. They usually start their career thanks to personal skills and hobbies which are followed by specialized training and certifications. 

While college degrees have become commonly required for pentesters, self-taught, or individuals with degrees in other disciplines of cybersecurity or IT still have a solid entryway to the field. 

Aspiring pentesters usually get their first job as Junior Penetration Testers. Middle-level roles include Penetration Tester which then advances into senior roles such as Senior Penetration Tester. 

In order to land that first job as a pentester, there are several steps to take. 


Start with the basics

The first step to kickstarting your pentesting career is a strong foundation. Good knowledge of the skills we highlighted above and an understanding of foundational cybersecurity concepts are crucial. There are several resources available to help you get a grasp on the fundamentals of penetration testing. OffSec’s PEN-100 is the ideal training to equip aspiring pentesters with confidence towards their career goals and prepare them with prerequisites for entry-level roles.  


Build a portfolio and a professional network

Before applying for pen testing roles, a good portfolio and presence in the community can be a good push. Furthermore, if you are coming from an unrelated field, a good portfolio that showcases skills and activities will get you in front of employers. You can build your pentesting portfolio by writing pentesting-related scripts or programs, and starting a blog to share your activities. 

Getting involved with the community is a great way to build a presence so make sure to have a professional LinkedIn profile, connect with industry experts, and contribute to open source projects. 


Take cybersecurity training and get certified 

Employers commonly want to see professional certifications when they receive your resume. Taking industry-leading courses and obtaining respected certifications is an important step in any pentester’s career path.
