How Vulcan Cyber ExposureOS determines the EOL of OS version
Vulcan Cyber ExposureOS uses a reliable open-source project called end-of-life.date to pull important EOL indicators for assets of the type Host and present them on the Vulcan Cyber ExposureOS platform. The site provides general knowledge regarding operating system versioning, maintenance policies, and support levels and provides an API to query the End-of-Life data of each OS version.
Vulcan Cyber ExposureOS determines the EOL of each OS version according to the following Support EOL policies:
Operating System | EOL Indicator in the Vulcan Cyber ExposureOS platform |
The Vulcan Cyber ExposureOS OS EOL indicator is the Standard Support end date.
For LTS versions, Standard Support ends after five years.
For development versions, Standard Support ends after one year. | |
The Vulcan Cyber ExposureOS OS EOL indicator for CentOS Stream is the Standard Support end date (5 years after the release date).
For CentOS Linux, Vulcan Cyber ExposureOS marks all versions End-of-Life, except for the latest minor version of CentOS Linux 7. | |

Apple does not publish end-of-life schedules for its products. Generally, once Apple releases a new major, a security update is also released for the prior two operating system releases.
Note that Apple's security updates are not necessarily applied to non-latest releases. | |
Windows | Generally, Windows has two major support levels: Pro and Enterprise, which offer two and three years of support, respectively. The Vulcan Cyber ExposureOS EOL OS indicator marks End-of-Life products according to the information provided on Windows 10 and Windows 11 release information sites. Windows versions before Windows 10 (Windows 8.1, Windows 7, etc.) are automatically considered End-of-Life. |
Windows Server has one release channel called the Long-Term Support Channel (LTSC).
