ERA components and architecture

To perform a complete deployment of the ESET security solutions portfolio, the following components must be installed:

ERA Server (controls the communication with client computers)

ERA Web Console (browser-based user interface for the ERA Server)

ERA Agent (deployed on client computers, communicates with ERA server)

The following supporting components are optional, we recommend that you install them for best performance of the application on the network:

Apache HTTP Proxy

RD Sensor (can detect unmanaged computers on the network)


ESET Remote Administrator Server (ERA Server) is the application that processes all data received from clients that connect to the Server (through the ERA Agent).


The ESET Remote Administrator Agent (ERA Agent) is an essential part of ESET Remote Administrator 6. Clients do not communicate with the Server directly, rather the Agent facilitates this communication. The Agent collects information from the client and sends it to the ERA Server. If the ERA Server sends a task for the client - it is sent to the Agent which then sends this task to the ESET endpoint product running on the client.

Web Console

ERA Web Console is a browser-based user interface that allows you to manage ESET security solutions in your environment. It displays an overview of the status of clients on your network and can be used to deploy ESET solutions to unmanaged computers remotely. If you choose to make the web server accessible from the internet, you can use ESET Remote Administrator from virtually any place and device.

Apache HTTP Proxy

Apache HTTP Proxy is a service that can be used in combination with ESET Remote Administrator 6.x to distribute installation packages and updates to client computers. It acts as a transparent proxy, meaning it caches files that have already been downloaded to minimize Internet traffic on your network.

Using Apache HTTP Proxy offers the following benefits

Downloads and caches the following:
- Detection engine updates
- Activation tasks, including communication with activation servers and caching of license requests
- ERA repository data
- Product component updates
...and then distributes them to endpoint clients on your network.

Minimized internet traffic on your network.


Rogue Detection Sensor (RD Sensor) searches your network for computers not registered in ESET Remote Administrator. This component can locate new computers and add them in ESET Remote Administrator automatically.

Remote detection sensor can take up to 24 hours to locate new computers on your network.

Newly discovered machines are listed in a predefined report, making it easy to assign them to specific static groups and begin assigning them tasks.
