networks ◦ forensics ◦ research ◦ consulting & training


We are good at...


If you teach, design and develop networks for several years, you master a lot of protocols and technologies. However, we are not a bunch of academics disconnected from the reality! We can solve real-life problems of our customers by having an objective view and applying reasonable thinking. We are ready for your mission-specific networking troubles.


Have you ever wonder how to find a needle in a haystack? We do! That is the reason why we focus on networking forensics. If you want to find meaningful information in terabytes of captured data or if you are struggling with your cryptocurrency related investigation, we can help you. We gathered a lot of experience from our cooperation with government institutions.


We have a strong academic background! Our products originated from our cooperation with research institutions. We were participating in various research grants and projects focused on cybersecurity and privacy. We support a collaboration, thus, we try to publish our results at global conferences.


We love to share our knowledge and know-how with others! Furthermore, teaching is our daily bread at the university. We customize training according to the specific needs and request of our clients. We are proud of our certification portfolio (including industry-recognized exams by Cisco, Microsoft, Red Hat, Juniper, Google).


We are publishing slides and materials from our public appearences via blog posts.


We established limited liability company netsearch s.r.o. in order to commercialize our know-how and products.
