If you spend more on coffee than on IT security, you will be hacked. What's more, you deserve to be hacked.

About us

The Network Security Solutions [N-SECURITY.COM] is the answer to market need for high quality server and network infrastructure management. We do not do everything, but what we do is perfect.

Never make the same mistake twice. Any task worth doing is worth doing right, and any task worth doing twice is worth automating. Anything that is broken needs to be fixed, and everything that works should be monitored. It's a simple set of ideals that can be challenging in practice, but is required to build a stable and usable environment.

—Our Mission Statement

Company story

Network Security Solutions was founded by experienced IT specialists, as an answer to market need for a pure networking company, which can build secure and stable networking environments while maintaining the highest quality of services. Our experience in previous companies and projects we worked for taught us, that in most cases the inner company communication, as well as too much "paper work" is too expensive and leads to lower quality products. We believe that in our own company we can fix it and make a networking world a better place.

Our principles

We stated basic principles, that we see as crucial in successful delivery of a stable and secure network environment project:

• we tend to give client what he needs, not what he wants
• we believe in open communication with client
• client is not our enemy
• "strict" is for corporations, we believe in "flexible"
• teamwork - share victory, share defeat

linux server management

Hardware is easy to protect: lock it in a room, chain it to a desk, or buy a spare. Information poses more of a problem. It can exist in more than one place; be transported halfway across the planet in seconds; and be stolen without your knowledge.
— Bruce Schneier

The biggest gain for us is to see the project in live state. We are serious about each one we have. Server security and customer satisfaction are the most important things for us.

—Our Mission Statement

What we do best

We specialise in linux / unix server and large network environments management. We think, that every need deserves a custom solution, as in most of cases it is cheaper and easier, than a ready solution with after-integration pain. We deliver individual solutions, that best fulfill need of our clients. The impact is put always on high quality and technological innovation of the project.

Technologies we use

We use a set of technologies we think are best suitable for big projects and those we have experience with, although we do not limit ourselves to them only. We constantly seek for new horizons, new trends and test them, so when they become mature, we can make use of them in our work. Network Security Solutions is always in search of new possibilities.
