Pros
Kaspersky Lab has very high standards. And it belongs not only to product's and protection quality, but also to the level of employees and conditions in the office. The work is interested, because IT security is a burning issue now. And you have a chance to work with people who develop the best protection and to be one of them. In the office you have everything you need to work and even more. Since Kaspersky Lab is not a young company, it has its own traditions that do not change. These traditions unite the company and though it is quite big, you still feel that each person is important.
Cons
You have to work to be the best of yourself.
