The Importance of Microsoft Extended Security Updates

In today’s rapidly evolving digital landscape, it’s crucial to keep your software up to date, not only to benefit from new features but also to protect your systems from security vulnerabilities. However, we understand that upgrading software can be a daunting task, especially when dealing with legacy systems. That’s where Microsoft Extended Security Updates (ESU) and Redcentric come to the rescue.

What is Microsoft ESU?

Microsoft Extended Security Updates (ESU) is a lifeline for older software that has reached the end of its standard support lifecycle. In a recent conversation with Redcentric’s cloud expert, Mark Harrison, we uncovered the essential details about ESU and why it’s imperative for your organisation.

In response to the popular demand to extend the length of time that security updates are available, Microsoft introduced ESU. This initiative ensures that even older software can continue to receive critical security updates, mitigating security risks for your organisation. In the past, ESU was only available through volume license agreements with software assurance, but now, as of October 1st, you can purchase ESU directly through Cloud Solution Providers (CSP) like Redcentric.

Why is ESU Important?

Security Vulnerabilities:

Outdated software is a prime target for cyberattacks. As technology advances, so do the tactics and tools used by malicious actors. Any vulnerabilities or loopholes in older software versions can be exploited, putting your data and systems at risk.

Data Protection:

Your business data is precious. With each passing day, the amount of sensitive information stored on your servers increases. Without security updates, you risk exposing this data to threats. ESU ensures that critical security patches are available to safeguard your data.

Regulatory Compliance:

Many industries and regions have strict regulations regarding data security. Failing to update your software may result in non-compliance, which can lead to hefty fines and legal consequences.

Continuity and Reliability:

Outdated software may not be as reliable as modern versions, leading to potential downtime. In the event of a security breach or system failure, the costs can be much higher than investing in ESU.

So, why should you consider ESU for your legacy software? The answer lies in security. If you’re still using products like Windows Server 2012 and have no immediate plans to upgrade, you won’t have access to security updates. If you’re still using products like Windows Server 2012 and have no immediate plans to upgrade, you won’t have access to security updates and leaves your system vulnerable. With ESU, you can gain access to critical security patches for up to three years, reducing your security risk.



Microsoft Extended Security Updates (ESU) are a lifeline for businesses relying on older software versions. With the ever-evolving landscape of cybersecurity threats, keeping your software up to date is non-negotiable. Whether you choose to upgrade to a newer version or invest in ESU, you’re taking a proactive step towards safeguarding your data, ensuring compliance, and maintaining the continuity and reliability of your systems. Your digital security is an investment, not an expense.

If you have any questions about ESU or need assistance in implementing security updates for your systems, don’t hesitate to reach out to us. Your business’s future may depend on it.
