can someone help if I buy kasperksy business space security for 25 workstations/file servers, how many licenses will I have for workstations/file servers. Or do I have an option to select how many I want for workstations / file servers .
thanks

If you buy a license for 25 nodes, it's the whole amount of workstations _and_ fileserver (ex. 20 wks / 5 fs or 15 wks / 10 fs).

ok thanks but 1 more question in this case if I buy licences for 25users is it possible in the future to buy more licences may be up to 100 without any problem because I am expecting my business to grow.

Yes you can. You can upgrade the license every time.

If you are sure will have 100 users in your plan, then you should call local distributor to get a better rate.
