Hi, I’m Tomasz an Information Security Professional. I am constant learner interested mainly computer security. My passion for information technology and security extends beyond my employment, and as such there’s a few reasons that this blog exists. I love learning in structured way so this is the reason I have obtained several certifications related to information security and not only:

  • CompTia Security+
  • CompTia Linux+
  • eLearnSecurity Junior Penetration Tester (eJPT)
  • Virtual Hacking Labs Penetration Testing
  • Offensive Security Certified Professional (OSCP)
  • PRINCE2 Foundation
  • SANS SEC560: Network Penetration Testing and Ethical Hacking (GPEN)
  • Certified Red Team Professional (CRTP) by PentesterAcademy
  • Certified Red Team Operator (CRTO)

Some of my certifications can be viewed online here: https://www.youracclaim.com/users/tomasz-w1

In short I wanted to have:

• A place to consolidate and publish some ‘Capture The Flag’ achievements and my thought process which lead to these achievements.
• A place to publish some of my public research, thoughts, and learning outcomes to help others improve themselves and their processes relating to information and cyber security.
• To lower the barrier of entry for upcoming security professionals who are interested in breaking into the field but don’t know how.
