## What is Tier4?

Tier4 is a fully automated Managed Detection and Response (MDR) platform. We integrate with your endpoint detection, identity, email, ticketing, and more to help protect your organization.

## How to Get Started

To get started, check out our [Onboarding](/onboarding/getting-started) section on the left-hand navigation to get your first tenant fully partitioned. Once your tenants and users are ready, you can add your first [Integrations](/integrations/introduction) and start processing alerts immediately.

## Have Questions?

If you have a question or issue with the platform, send an email to [support@tier4ai.com](mailto:support@tier4ai.com).
