[vc_row][vc_column][vc_column_text css=".vc_custom_1539609676136{margin-top: 3% !important;}"]Penetration tests (or pentests, in short) are simulated attacks carried out in a controlled environment by third-party security specialists. A pentest will reveal whether an organization is potentially vulnerable to cyberattacks and provides recommendations on how to strengthen its security posture. Given today’s ever evolving cyberthreat landscapes, penetration tests have become one of the most-commonly known security tactics to help organizations uncover critical vulnerabilities, strengthen their security defenses and meet compliance requirements such as PCI DSS.

There is a large demand for skilled professional penetration testers or so-called ‘ethical hackers’, and more and more security professionals pursue relevant certifications such as Certified Ethical Hacker (C|EH), Licensed Penetration Tester (LPT), Certified Penetration Tester (CPT) or GIAC Penetration Tester (GPEN). In fact, a 2016 research report revealed that the penetration testing market is estimated to triple in size from USD 594.7 million to USD 1,724.3 million between 2016 and 2021.

Curious about how to stay up to speed? We’ve gathered 10 useful resources vetted by’s own Penetration Testers that will help you keep up with the rapidly evolving landscape of ethical hacking. Make sure to bookmark this blog and check back regularly for updates!


Top 10 Pentesting Resources


  1. Offensive Security

Offensive Security is an industry-leading information security training and penetration testing website, offering trainings and certifications, virtual penetration testing labs, etc. Offensive Security provides safe virtual network environments through its penetration testing labs to help aspiring and seasoned penetration testers acquire and enhance their penetration testing skills.

  1. PentesterLab

PentesterLab provides a collection of penetration testing labs of varying degrees of difficulty to help penetration testers understand and test systems for vulnerabilities. By completing the online exercises, penetration testers can earn certificates of completion, such as the Capture-the-Flag Badge, the Authentication Badge or the Serialize Badge.


  1. Cybrary

Cybrary is possibly one of the best information security education sites on the internet. It contains full-length college course videos for everything from basic networking up to and including training for certifications, explanations of secure coding, penetration testing and everything else security related.

  1. Ethical Hacking LinkedIn Group

Ethical Hacking is a LinkedIn group specifically created for ethical hackers to have a medium for exchanging knowledge, ideas and techniques specific to penetration testing. Some of our own Penetration Testers have joined this LinkedIn group to stay abreast of trends & best practices.


  1. Kioptrix

Kioptrix is a hands-on, practical blog that provides penetration testers with flawed Operating System images that they can download. Once downloaded, they can set up their own virtual machine and try attacking these Operating Systems to learn about the most common vulnerabilities and security holes.


  1. is yet another great resource for free content about penetration testing and vulnerability scanning, including a directory of relevant open source tools, penetration testing and Metasploit tutorials, blog articles, videos etc.


  1. GitHub – Awesome Penetration Testing

GitHub is home to over 20 million developers working together to host and review code, manage projects, and build software together. GitHub has compiled a post called “Awesome Penetration Testing” that lists a collection of “awesome penetration testing resources, tools and other shiny things”. In short, it really is awesome because it’s one of the most complete lists we’ve found. Penetration testers can find resources about vulnerability databases, report templates, books, security courses, conferences, magazines etc.
