# Elastic Defend requirements
To properly deploy Elastic Defend without a Mobile Device Management (MDM) profile, you must manually enable additional permissions on the host before Elastic Endpoint—the installed component that performs Elastic Defend's threat monitoring and prevention—is fully functional. For more information, refer to [Enable Elastic Defend access on macOS](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4946/solutions/security/configure-elastic-defend/enable-access-for-macos).
For information about supported operating systems, refer to the [Elastic Support Matrix](https://www.elastic.co/support/matrix#elastic-defend).
