Extended Security Updates - Description

What are Extended Security Updates (ESU)?

Extended Security Updates (ESU) are a Microsoft service that provides critical security patches and fixes for their products beyond the end of the standard support period. ESU ensures that businesses can maintain security and compliance for legacy software systems while they transition to newer technologies. This program is especially crucial for systems that handle sensitive data, where continuous protection against vulnerabilities and threats is necessary even after the general support lifecycle has ended. ESU allows organizations to protect their investments, maintain operational continuity, and reduce risks as they plan and implement their upgrade strategies.
