The vRealize Log Insight virtual appliance uses VMware Photon 3.0 as the guest operating system.
vRealize Log Insight 8.0 or later comes with a Photon operating system. Photon is more secure than the SLES operating system, which accompanies vRealize Log Insight 4.8 or earlier.
VMware releases patches to address security issues in maintenance releases. You can download these patches from the vRealize Log Insight download page.
Before you apply an upgrade or patch to the guest operating system, consider the dependencies. See Ports and External Interfaces.
