# Elasticsearch Serverless add-ons
Elasticsearch Serverless projects currently support the optional **Serverless Plus** add-on.
The Serverless Plus add-on is a package of enterprise features that help you to secure your data and enhance your data insights.
Serverless Plus includes the following features:
- Network security features, including [IP filtering](https://www.elastic.co/elastic/docs-builder/docs/3016/deploy-manage/security/ip-filtering-cloud) and [private connectivity](https://www.elastic.co/elastic/docs-builder/docs/3016/deploy-manage/security/private-connectivity)
- Coming soon: Cross-project search

In future, Serverless Plus will include the following additional features:
- Cross-project replication
- Encryption at rest with customer-managed keys

This add-on is currently free for a limited promotional period. Enabling or using these features opts your project in to Serverless Plus. [Learn more](/elastic/docs-builder/docs/3016/deploy-manage/deploy/elastic-cloud/project-settings#serverless-plus).
