ESET makes the only product ever to win 100 VB100

Virus Bulletin, an independent testing organization, presented its first Virus Bulletin Award (VB100) in 1998 and to this day is considered to be the most renowned accolade in the industry. With an unbroken record over 18 consecutive years, no other security product can claim to be the top performer by this independent testing and certification body. 

IT, project management? First class. Deployment? Brilliant. Users? They never even noticed a change in the environment. Technical resources? Fabulous.

Tony Cooke, IT Director, CCS Media Limited, UK

As an IT I’ve been worry-free since the first time we used it and I’m still worry-free now. It has made my life as an IT much easier.

Anthony Avestruz, Senior Technical Support Engineer, Honda Philippines, Inc.

I'm in IT, as a support consultant, and I cannot stress how many times I come across a machine that is running "Free" protection that has been compromised. ESET products are well priced, well supported and besides using a fraction of system resources compared to other brands, they are effective.

Deon Seymour

I use ESET NOD32 Antivirus on my PC and Mac at home, work and while traveling. It works quietly behind the scenes without ever interrupting what I do.

Debbie M., United States

ESET, you are absolutely the finest in researching threats and malware. That's why I will never use any other antivirus software and I love that I upgraded to Smart Security. Your software is worth every penny. I am forever grateful to you and all that you do.
