If you need a specialist appliance, such as an intranet search engine, you probably find that it's impossible to get it for a reasonnable price. You can choose a professional product with extensive support but it will cost you a fortune. You can put together open source solutions on a dedicated box but you might not have the skills to do so and maintenance will end up costing you a lot. Pre-Emptive are here to solve this problem. They can provide you with a "solution in a box", i.e. they will provide you with a computer that has all the right bits configured and running to solve your problem and that you can just drop into your network. The acquisition cost is low because the solution is based on open source technology; maintenance is minimal because Pre-Emptive does it for you. Hence a low TCO and a happy CFO.
