The Impact of Microsoft’s EOS/EOL on Security and Compliance

As the end of support (EOS) and end of life (EOL) for various Microsoft products approaches, it’s essential for organizations to comprehend the implications and prepare for the transition. Ensuring compliance and maintaining robust security measures are of paramount importance in today’s business environment. In this article, we will discuss the upcoming end-of-support dates, the significance of compliance and security, the risks associated with using unsupported software, and provide guidance on preparing for these changes.

Interconnected and digital world

Key Dates and Products Affected

Microsoft follows a well-defined support lifecycle for its products, generally offering support for 10 years after a product’s release. Several popular Microsoft products will reach the end of their support lifecycle as we approach 2023, including:

  • Windows 8.1: January 10, 2023
  • Windows Server 2012 and 2012 R2: October 10, 2023
  • Internet Explorer 11: June 15, 2022

A comprehensive list of Microsoft products and their end-of-support dates can be found on the Microsoft Lifecycle Policy website.

The Importance of Compliance and Security

In an increasingly interconnected and digital world, organizations must prioritize compliance and security to mitigate risks, protect sensitive data, and maintain trust with customers, partners, and regulators. Compliance ensures that organizations adhere to industry-specific rules, regulations, and standards, such as GDPR, HIPAA, and PCI-DSS, while security focuses on safeguarding digital assets, networks, and systems from unauthorized access and cyber threats.

A proactive approach to compliance and security helps organizations:

  • Protect sensitive data and intellectual property
  • Avoid financial penalties and legal consequences
  • Preserve brand reputation and maintain customer trust
  • Ensure business continuity and minimize downtime

The Consequences of Unsupported Software

Continuing to use software beyond its end-of-support date can expose organizations to several risks, such as:

Security Vulnerabilities

Unsupported software no longer receives security updates, leaving systems vulnerable to new threats. According to a study by the Ponemon Institute, the average cost of a data breach in 2021 was $4.24 million, a significant financial risk for organizations. Furthermore, a report by Avast revealed that 55% of all installed applications worldwide were out-of-date in 2019, increasing the risk of security breaches.

Compliance Issues

Organizations subject to regulatory requirements, such as GDPR or HIPAA, may face penalties for using unsupported software. Non-compliance can result in fines, legal action, and reputational damage. For example, the maximum fine under GDPR is up to €20 million or 4% of annual global turnover, whichever is higher.


Unsupported software may become incompatible with newer applications and technologies, leading to reduced productivity and increased IT support costs. According to a study by IDC, organizations can expect to spend approximately 30% more on IT support when using outdated software.

proactively plan for these changes

Prepare Now

The end of support for Microsoft products presents both challenges and opportunities for organizations. By proactively planning for these changes, and prioritizing compliance and security, you can minimize risks, reduce costs, and leverage new technologies to drive your business forward. Don’t wait until the final countdown; start preparing for the end of support today.
