Piotr Zenon ŻabrowskiEnterprise Security Advisor | Cloud & SI Security Architect | Security Leader

"I had the pleasure of working with Piotr over the past few years in various capacities—both as a one-man army, when he was responsible for IT security at Ceneo, and as an IT security expert at Allegro. Piotr possesses extensive knowledge in many areas and is always eager to share it, whether with members of the IT security team or within the entire IT department. Thank you, Piotr, for these years of collaboration, your support in numerous security investigations, and the excellent cybersecurity training sessions—especially in OSINT. I also greatly appreciate your insights into security in public clouds and LLM/AI, to name just a few highlights. Wishing you the best of luck in your future endeavors!"

"Together with my team, I had an opportunity to collaborate with Piotr on multiple initiatives related to the MLOps platform. Piotr is a great security specialist, having an extensive and up to date domain knowledge. Openness for a discussion, grasping the wide perspective and willingness to help and support are surely his advantages."

"Piotr, in addition to possessing extensive knowledge and experience, willingly shares it on internal and external forums. We had the opportunity to collaborate multiple times in knowledge-sharing initiatives and employer branding activities. Each time, Piotr demonstrated initiative, paid careful attention to the form and content of his presentations, sought improvements in this area, and honed his skills. He is undoubtedly a popularizer of security topics in his industry and beyond, an excellent speaker, and a committed colleague. Piotr is also one of those individuals who can professionally and consciously represent the company in public forums."

"I highly recommend Piotr as an exceptional IT Security specialist. He possesses extensive knowledge in his field, combined with strong analytical skills that enable him to make quick, accurate decisions. Piotr is dedicated to identifying security risks and resolving them effectively, working collaboratively with others. His supportive attitude is a valuable asset to any team. Piotr is absolutely worth of recommendation."

"During my time at Allegro, I've had the opportunity to work with Piotr, who was our liason to our company's SEC team. Piotr helped establish and enforce a clear security strategy for our Azure-based products, which led to global increases in our subscriptions' secure-scores. In addition we always knew we could depend on his support, when facing a security-related challenge. All things considered, I'd be very happy to work with him again, and wish him best of luck in the future"

"I highly recommend this Allegro expert! In our team, we could always rely on him—whether for quick reactions to unexpected situations or daily support. He knows the topic inside out and can find a solution where others would give up. Working with him means peace of mind about security and certainty that everything is under control. I recommend him to anyone looking for someone with extensive knowledge and a great approach to work!"

"Definitely recommended! Piotr is a reliable and insanely knowledgeable expert with great communication skills and work ethic."

"I have had the opportunity to work with Piotr on a number of occasions and have always been impressed by his wide-ranging, off-the-charts knowledge. One of the qualities that I particularly appreciate in Piotr is his inquisitiveness and thoroughness - Piotr never "lets go" and sees every matter through to the end. In addition, it is worth noting that Piotr is good to listen to and one of the most interesting training sessions (about OSINT) I have had the opportunity to attend was his own training. I sincerely recommend working with Piotr!"

"Piotr can navigate even the most seemingly hopeless situations and find a way out of them. He pokes holes in everything, plays devil's advocate by asking tough but justified questions that have more than once revealed new perspectives or clever solutions. He always sees tasks through to completion. He can explain the intricacies of IT or security in an understandable way. Moreover, he is collegial and reliable. I'm glad I had the pleasure of working with Piotr on several projects."
