As new versions of Windows or Linux operating systems are released, the original product guides might not reflect the current Technical Support policy for those platforms. This article provides the latest information about the supported platforms and environments. It's updated periodically to reflect the current state of support for the SIEM ESM. Most of the following information is available in the ESM installation guide. But, some of the information is available only in Product Management statements published in the Knowledge Base.



SIEM is managed and maintained through HTML5 and some settings through the flash interface. The minimum requirements for a host connecting to the ESM are provided in the following tables.

NOTE: We strongly recommend that you upgrade to the latest available version to benefit from all enhancements and resolved issues.

System requirements

Hardware Component	Requirement
Processor (CPU)	P4-class Intel® (not Celeron) or later (Mobile/Xeon/Core2/Core i3/5/7) AMD/AMD2 class or later (Turion64/Athlon64/Opteron64/A4/6/8)
Memory (RAM)	16 GB

Virtual Machine requirements

NOTES:

• The SIEM VMs use many features that require CPU, RAM, and high-performance disks. If the ESXi environment shares the CPU and RAM requirements with other VMs, the performance of the ESM VM might be impacted. So, it's highly recommended that you use dedicated resources and high-performance SSDs.
• ESM 10.3 and later VMs can be created on the Azure, Hyper-V 2016 and later, and XEN 6.5 and later platforms.  

Hardware Component	Requirement
Processor (CPU)	8 core 64-bit, Dual Core2/Nehalem or later AMD Dual Athlon64/Dual Opteron64 or later
Memory (RAM)	16 GB or more (depending on model)
Disk space	500 GB or more (depending on model)
ESXi Server	5.0 or later
Thick or Thin provisioning	You must decide the hard disk requirements needed for your server. The minimum requirement is 500 GB unless the VM purchased has more. See the specifications for your VM product.

See the following KB article for more information: KB78434 - Product support for Windows XP SP3 after the end of the Microsoft Extended Support date in April 2014.

Microsoft ended extended support for Windows Server 2003 SP2 on July 14, 2015. As of the end of 2015, the only product we support with Windows Server 2003 SP2 is Application and Change Control.

Internet browsers

The following web browsers are supported with the ESM. Because some features of the web application use pop-up windows, Technical Support recommends that you allow pop-ups for the IP address or host name of the ESM.
 

Browser	Version Needed
Mozilla Firefox	Version 42 or later
Google Chrome	Version 48 or later
Apple Safari	Version 5.1.7 or later

Cloud services

SIEM products that are listed above support the following cloud services:

• Amazon Web Services
• Oracle Cloud Infrastructure
• Microsoft Azure

This support enables a virtual deployment of the ESM. The ESM monitors and reports on cloud servers and other types of security infrastructure that are supported in its cloud environments.
 

NOTE: Flash Player is no longer supported starting from January 1, 2021. The ESM Administrator Application needs to be used to mitigate Flash.
For more details, see KB93257 - SIEM Flash Mitigation (you are unable to access the SIEM ESM UI).
