# About SSP

The SSP concept is common in the online world and an important part of the digital out of home (DOOH) world.

Grassfish provides a solution for playing both DOOH and SSP content.

## What is SSP?

Simply put, a supply-side platform (SSP) is a programmatic advertisement platform that allows you to play spots.

Usually, SSPs work with demand-side platforms (DSPs) to distribute advertisement spots to advertisement spaces.

## DOOH and SSP module

Grassfish’s DOOH and SSP module provides a controlled and transparent interface to programmatic advertisement platforms, allowing the network owner to define rules and control media playback.
