ESET Research Czech Republic

The beginnings of ESET date back to 1987, when two young programming enthusiasts, Peter Paško and Miroslav Trnka, wrote a program for the detection of one of the world’s first computer viruses. They did not know that they had created one of the most successful antivirus programs in the world – dubbing it NOD. In 1992, together with their mutual friend Rudolf Hrubý, they formally established ESET.

What started as the brainchild of a few friends has evolved into the most valuable international brand of any Slovak company. Today ESET’s NOD32 technology protects over 100 million users across the world.

This success did not come overnight. The company’s global success and growth was given a boost in 1998 with its first “VB100” award from the prestigious Virus Bulletin magazine. Since then, we’ve received this accolade more than 100 times.

Today, over 1,700 employees around the world drive the company’s success. Throughout the company’s expansion, we have stayed true to the principles on which we were founded, and we remain independent in order to continue to meet new challenges.

Now it's up to YOU!
You really only need to send your CV
