EOL (End of Life) is a designation used in cybersecurity and IT to indicate that a product, software, or hardware is no longer supported or produced by its manufacturer. Once a product reaches EOL, the vendor stops providing updates, patches, and technical support. This can lead to security risks, as vulnerabilities discovered after EOL will not be addressed, leaving systems exposed to potential threats. Organizations using EOL products are advised to upgrade or replace them to maintain security and compliance. Proper management of EOL assets is crucial for minimizing operational and security risks within an IT environment.
