Note: Windows Server 2012 R2 on an AWS T3 instance requires a workaround for agent not showing in console:

  • Upgrade the OS.
  • If you cannot upgrade the OS, apply this policy override:
    • Put all AWS instances of Windows Server 2012 R2 in one endpoint group.
    • Create this policy override for that group:{ "blockUnsignedDriverLoad": false }
  • If you cannot group the endpoints (they are not in the same Site or there are other restrictions), create an exclusion for the problematic Windows driver:C:windowssystem32driversena.sys
  • If none of these steps are relevant, open a support case directly with Microsoft to fix the issue.

All Windows Agents, starting from version 21.5.2, fully support Windows 11.

All versions of Agents that are supported according to the lifecycle are tested for compatibility for each Windows 10 release.

Some Deep Visibility functionality is not fully supported on Windows 10 Redstone 5 (October 2018 Update) with 2.5, 2.6, and 2.7 Agents. If you upgrade a Windows 10 endpoint to RS5, TCP connection events are reported for Windows Agents of version 2.8+.

Important: For Agents installed on Windows 8.1 and Windows Server 2012 R2:  To update the OS with Microsoft Updates, click this link. These updates are required for the endpoints to connect to the Management. If you do not download these updates, the endpoints will be rejected by the Management due to weak SSL.

Microsoft ended support for Windows 7, January 2020. SentinelOne continues to support Agents on Windows 7 for up to three years after the Microsoft End Of Life declaration. Windows 10 offers a much better security architecture than Windows 7, and the Agent on Windows 10 supports these enhanced security features. Therefore, we strongly advise that you migrate your endpoints to Windows 10.

Windows Defender On Windows Servers, Microsoft Defender Antivirus do not enter passive or disabled mode if you have SentinelOne installed. We recommend that you uninstall Microsoft Defender Antivirus on Windows Servers to prevent interoperability issues.

The behavior when an Agent is installed on an endpoint with Windows Defender installed differs depending on the Windows OS version.

.NET Framework 4 and later on Windows 7 and Server 2008 R2 for the old EXE installer (earlier than Agent version 22.1). Not needed for the MSI installer or the new EXE installer (Agent version 22.1+).
On Windows 10 version 1607 and Windows Server 2016, install Microsoft KB4093119, to make sure old logs in ProgramDataSentinellogs are deleted. An endpoint should have only 16 log files, taking up no more than 1.6 GB.
On Windows 8.1 and Windows Server 2012 R2, install update 2919355 to enable new TLS cipher suites.
On Windows 7, Windows 7 Service Pack 1 (SP1), Windows Server 2012, and Windows Server 2008 R2 SP1, install the Update to enable TLS 1.2 as default secure protocols in WinHTTP and add the Registry subkey, as shown in the article. Management-Agent communication uses TLS 1.2. This is not supported by default in Windows 7. You must install this update and add the registry subkey, as shown in the article.
KB3033929 (SHA2) – Security Update for Windows 7 SP1 and Windows Server 2008 R2. This security update must be installed on Windows 7 SP1 and Windows Server 2008 R2 SP1 to meet minimum requirements for the installer.
KB2758857 for Windows 7 and Windows Server 2008 R2 or KB4457144 – Security updates for Windows 7 SP1 and Windows Server 2008 R2 After you install the security updates, you must restart the endpoint and run the Agent installation again.
Microsoft Windows Volume Shadow Copy Service (VSS) Configure VSS before you install the Agent.
GPO Chrome Extensions The SentinelOne Chrome extension is part of the Agent installation. When you install or upgrade the Windows Agent with GPO, Chrome extensions must be enabled.
GPO Privileges The administrator who runs Agent installation through group policy must have RESTORE and TAKE OWNERSHIP privileges to prevent an installer crash.
DigiCert If the endpoint does not get Windows updates, you must manually install DigiCert for the Agent to communicate with the Management.
Windows Root Certificates Update Windows Root Certificates. If you do not, it could lead to invalid signature errors.
