# Security identity cache
The {doctitle} is a [Coveo organization](https://docs.coveo.com/en/185/) module that stores [security identities](https://docs.coveo.com/en/240/), their properties (such as their state and last update timestamp), and their [security identity relationships](https://docs.coveo.com/en/243/).

This cache greatly speeds up [query](https://docs.coveo.com/en/231/) processing time when evaluating the [effective permissions](https://docs.coveo.com/en/194/) of an [item](https://docs.coveo.com/en/210/).
