# Why does the price jump when we add sites, segments or modules?

Because many security products are priced per sensor, per site or per module, so growth that seems small to you means new hardware, licences and services for the vendor. A second office can mean a second appliance, a new segment can mean another sensor licence, and a feature such as encrypted-traffic analysis or OT monitoring can be a separate module with its own price. Before you sign, ask the vendor to price your likely next step: one more site, twice the devices, the module you will probably want next year. Check whether the contract caps renewal increases. With NetSenX, the unit is the device: a host running the agent, where one agent on a SPAN or TAP port counts as one device for the whole segment. Features come with the plan rather than as separate modules, and the plan catalog shows which plan includes what, so the cost of growing is visible in advance.
