End of Support Life (EOSL) is the date after which a software or hardware product no longer receives security updates, patches, or technical support from its manufacturer. Once a product reaches EOSL, it becomes increasingly vulnerable to security risks, as any newly discovered vulnerabilities will not be addressed. Organizations using products past their EOSL may face compliance issues and increased risk of cyberattacks. It is crucial for businesses to track EOSL dates and plan timely upgrades or replacements to maintain security and operational integrity. Ignoring EOSL can result in unsupported systems that are susceptible to exploitation.
