CentOS 7 Support for Post-EOL Security and Stability


June 30, 2024 marked the end of life (EOL) for CentOS 7. This critical milestone means the end of official updates, patches and security fixes, leaving your Linux systems vulnerable to attacks. The time is now to ensure your infrastructure remains secure, stable and compliant. 

While you may choose to migrate to a new operating system, you need to ensure support and security for the CentOS workloads that are running unprotected until your migration is complete. This is where post-EOL CentOS support comes in.

This article will detail the risks your CentOS systems face now that CentOS 7 is EOL and introduce a seamless solution for extended CentOS 7 support.

Quick Facts About CentOS 7 End of Life

Is CentOS 7 end of life?

CentOS 7 reached its end of life on June 30, 2024. As of July 1st, 2024, CentOS will no longer receive official updates, patches or support. For more details, read our comprehensive guide to CentOS EOL.

Is CentOS 7 still supported?

Official support for CentOS 7 has ended, meaning no more updates or security patches will be provided by the CentOS project. If you’re still running CentOS, your systems are at risk for cyberattacks and data leaks.

What replaces CentOS 7?

The current proprietors of CentOS advise a full migration to another operating system, as there is no official upgrade path available to another version of CentOS. You can choose to migrate to a new environment, or opt for a no-migration CentOS alternative with third-party support.

What is the future of CentOS 7?

Without official support, CentOS 7 systems are at risk for security vulnerabilities and operational issues. CentOS will keep running for the time being; however, it’s dangerous to rely on an OS that does not receive security updates. Secure the future of your CentOS workloads by transitioning to a supported solution.


Immediate Risks Post-CentOS 7 EOL

Running a sunsetted Linux OS puts your technology stack at risk. Specifically, these are the biggest threats you’ll face by continuing to run CentOS 7 without support:

  • Security Vulnerabilities and Cyber Threats: Without regular updates and security patches, your CentOS 7 systems are prime targets for cyberattacks. Unpatched vulnerabilities can lead to data breaches, loss of sensitive information and severe financial repercussions.
  • Operational Disruptions and Downtime: Unsupported systems are prone to failures and performance issues, leading to operational disruptions. Downtime can affect your business continuity, resulting in lost revenue and customer trust.
  • Compliance and Regulatory Risks: Running unsupported software can lead to non-compliance with industry regulations and standards. This can result in hefty fines and legal consequences, further jeopardizing your business.

These implications underscore the urgency of securing support for your CentOS workloads. The time has come to regain liberty and secure your IT future.
