What a person encrypts, a person can also decrypt. This was true a couple of years ago. Nowadays, cyber-criminals use advanced technologies and their attacks are much more sophisticated and targeted, and consequences are much worse. Not only the good guys (i.e. cyber protection companies) but also the bad guys are evolving. Attacks are aimed at weak points and human errors,“ says Petr Chaloupka, CEO of GREYCORTEX, a company that focuses on IT and industrial network security. The story of this company that succeeded among the fastest growing tech companies began long before its foundation. It is a story about passion, vision, skills and a ton of humour. And, in a way, it is connected to the beginning of computerisation in Czechoslovakia.

Maybe you too still have a vivid memory of this history chapter and maybe you remember 8-bit computers – or maybe you don’t. Luckily, there is Petr Chaloupka, the founder and CEO of GREYCORTEX, and his memories of a contest from the 90s, a text game passed around on cassettes and floppy disks that were created very long ago for 8-bit computers. Cassettes and floppy disks were… well, just google it, kids! This game was protected by a password that was announced on a certain day in the newspaper, on the radio and on TV to give everyone the same fair start. However, my friend and I didn´t feel like waiting and so, after several hours of reverse engineering, we identified the password and came to the conclusion that what a person encrypts, a person can also decrypt. And that is maybe where my lifelong passion for cybersecurity started and this seemingly innocent story signalled my future professional career“.

A story of a company standing on the front line in the battle against hacker attacks

The first chapter of the GREYCORTEX story began around 2005. I was working on an antivirus for Linux, which was a completely insignificant platform for cybercriminals back then and for which there was no malware. There were only a few lab experiments for proving that there could be one. My colleague Michal Drozd used to hack banking systems using social engineering and customised malware“, reminisces Petr Chaloupka about the beginnings with a smile. The group includes another Petr – Petr Chmelař. Back then, he was working on machine learning principles that would be capable of finding video signal anomalies. A strong technology for which there may have been another use. What about transferring it from the video world into a computer network“? asks Petr Chaloupka rhetorically with a good portion of irony.

However, you are probably more curious about the ending of the first plotline, about Michal Drozd and his bank story. There was no shocker – Michal Drozd stood on the right side and banks paid him to do what he did. We would say today that he was an ethical hacker. However, if he had decided to become a cybercriminal, he would be very rich by now,“ adds Petr Chaloupka.

But let’s be more serious now. Fast forward fifteen years later. Petr Chaloupka sums up that Linux is a common and widespread platform, interesting enough for cybercriminals to attack. GREYCORTEX is now a well-established company focusing on the development of security products for network protection, machine learning and AI research, and the second fastest growing tech company in the Rising Stars category of the Deloitte Technology Fast 50 competition.

Were we visionaries back then? I don’t know. Maybe we were just the three right people at the right place, and if we had never met, nothing would have happened. Literally. But we did meet, a couple of good questions were asked and we started to look for answers together.“

Thorough and complete security

The second chapter of the GREYCORTEX story was about visionary questions in the end; for example, how can someone manage to break into a bank or any other company without having to leave their home? And how come they don’t get caught? Then the right answers came and with them the first specific solution.

Somewhere around 2014, things blended really well and when five more friends and colleagues joined us at the end of 2015, everything was ready to establish a company and start our business. It needs to be said that all founders are still with us in different roles in the company, helping it grow.“

Four years later, the company became five times as big. Our product Mendel’, which can uncover hidden threats in the network, from unknown devices to advanced attacks, has matured. After overcoming some childhood diseases and puberty, it is becoming a model for others – we helped introduce another branch of cyber security into the world! It used to be called NTA (Network Traffic Analysis) in the past; now it is called NDR (Network Detection and Response),“ says Petr Chaloupka.

Don’t worry if you are getting a little lost in all the information, you have a right to that and you deserve an explanation: NDR combines deep visibility into infrastructure with the capability to detect known and unknown attack and malware types and to react to them in real time. So, it is clearer now, isn’t it? Same as the fact that the world is changing, technologies are changing and we are changing with them. It is important that we have done our bit and continue to give cybercriminals a hard time and ruin their filthy and immoral business,“ remarks Petr Chaloupka.

What was the worst in the beginning? Even in our case, it holds true that all theory is grey, but the golden tree of life springs ever green, so we do everything in a completely different manner than we used to. However, the most important thing is that we learned to understand what it means not only to have a good product but also to sell it and persuade clients that they need it. You could say that we are selling insurance or that we are like Eastern medicine – we ensure that the client does not become infected and he pays us for not getting ill.“

To sum it up, Petr Chaloupka views success and failure as communicating vessels. A functioning and growing company is a success, even though it arose from humble financial background and was basically only a dream of a few founders some 6 years ago. From the beginning, we had a vision of building a global company and so our plans now are clear – to strengthen our position in the territories in which we already operate and gradually add other locations to reach our goal. It is definitely important to find balance between this dream goal and the need to have both feet on the ground (or at least one foot).“
