Jakub currently holds the position of junior consultant, pentester in the Guardians.cz team.
During his studies at high school specializing in computer network administration and then at a higher technical school in the field of system administrator, he discovered his passion for penetration testing and red teaming.
In addition to his workload, he is actively expanding his knowledge and skills by completing certification programs in cyber security. Some of the certifications he has attained include eJPT (Junior Penetration Tester) and eCPPT (Professional Penetration Tester), which demonstrate competency in performing complex testing processes and producing expert reports with recommendations for correcting identified vulnerabilities. In addition, he has completed courses such as the Cybersecurity Managers Course from NCIS, Ethical Hacker from Cisco, and an online course in Cybersecurity from Harvard University.
In his spare time, Jakub works on a personal project where he configures individual elements of the Red Team infrastructure. The goal is to create a functional unit to run operations securely. Jakub believes that by understanding the whole process, he will gain the know-how to create simulations and be able to capitalize on it to test the resilience of customers' security measures. He will also use the project in his graduate thesis on "Gaining initial access by leveraging social engineering".
His previous position was at innogy, where he was involved in security awareness training for both operational technology (OT) staff and general users. He also actively delivered workshops to demonstrate common cyber attacks from both the attacker's and victim's perspective. Among other things, he has been analyzing phishing emails.
