# 11. Server Agent

The agent installed by the “ERP Bridge Installer” it’s executed by the operating system as a service bind with the OS user selected during the installation and it has the same level of permissions.\
\
The software executes the connection with the ERP database using OIDC drivers accordingly with the DBMS technology selected during the installation wizard.<br>

![HOW ERP Bridge Server Agent works](https://www.erpbridge.io/images/HOW-ERP-Bridge-Server-Agent-works-Security.png)

\
The agent send data to our “ERP Bridge” cloud API only for the following specific cases:

* retrieve and refresh of HubSpot API auth token;
* refresh of “ERP Bridge” API auth token;
* retrieve the transcoding informations;
* check of the last run to match the installation scheduler settings;
* update of the last run’s timestamp;
* send logs and telemetry.

\
The sensitive information retrieved from the ERP database are sent directly to HubSpot using their HTTP REST API without sending a single customer data piece of information to the “ERP Bridge” cloud API. The same thing is true for files, they are uploaded directly to HubSpot using the HubSpot “Files API”.\
\
Logs and telemetry information sent to the “ERP Bridge” cloud are free of sensitive customer data but maintain useful information about crashes, HubSpot API errors, malformed data and more.\
\
The logs are stored using AWS CloudWatch service and it is configured with a retention of 2 weeks independently of the schedule set, in this manner the user can be sure that nobody will have access to the logs after that short period of time.<br>
