# EPM Windows agent requirements

This document describes the requirements for installing and operating EPM Windows.

## Requirements

To ensure proper operation:

1. Add EPM Windows to your [antivirus exclusions](/v4-2/docs/epm-windows-antivirus-exclusions).
2. Include EPM Windows as an exception in system hardening processes.

Attention

If you do not add EPM Windows to your hardening exceptions, it will not run normally.

## Hardware specifications

| Sessions | CPU Cores | RAM (GB) | Storage (GB) |
| --- | --- | --- | --- |
| Up to 50 | 4 | 4 | - |
| 50 - 100 | 8 | 8 | 8 |
| 500 | 16* | 16 | 16 |

* Requires the `pm.max_children` parameter set to 10. For sessions exceeding 500, consult the Segura® Platform support for tailored recommendations.

## Network requirements

EPM Windows needs outbound access to the following DigiCert URLs. Allow them on your firewall and proxy with these settings:

| Setting | Requirement |
| --- | --- |
| Port | `80` (HTTP) |
| Proxy authentication | None. Configure the proxy to allow these URLs without user authentication. |
| SSL inspection | None. Exclude these URLs from SSL inspection and decryption. |

DigiCert URLs to allow:

- `http://crl3.digicert.com`
- `http://crl4.digicert.com`
- `http://ocsp.digicert.com`
- `http://cacerts.digicert.com`

## Dependencies

| Component | Requirement |
| --- | --- |
| .NET | Microsoft .NET 9 Desktop Runtime ≥ 9 |
| Libraries | Microsoft Visual C++ Redistributable (2015-2022) x86/x64 |
| Segura® Platform | Version 4.2.14 or later, for the agent to complete the version-compatibility check during installation. Earlier versions aren't covered by the compatibility check, so the EPM agent's behavior isn't guaranteed. See [EPM version compatibility](/v4-2/docs/epm-version-compatibility-matrix) for the full policy, including behavior in earlier versions. |
