To automatically install Standard Endpoint Protection on PCs, you can use the Trend Micro Security Agent installer package to deploy the agent to Windows endpoints. Third-party deployment tools like Microsoft System Center Configuration Manager (SCCM) or Group Policy Object (GPO) can also be used for deployment.
