Keeping your server software up to date is essential to protect your business from cyber threats and ensure smooth day-to-day operations. Server software includes the operating system and any applications running on your servers, which need regular updates to fix security vulnerabilities and improve performance. For a UK small or medium-sized business, this means applying updates promptly—usually as soon as they are released or within a few days—to reduce the risk of cyberattacks and maintain compliance with standards like Cyber Essentials or ISO 27001.
Why timely updates matter for UK SMEs
Outdated server software can leave your business exposed to hackers exploiting known weaknesses. This can lead to data breaches, loss of sensitive customer or employee information, and costly downtime. For example, a ransomware attack might encrypt your files and halt operations, affecting staff productivity and damaging customer trust. Additionally, failing to keep software updated can put you at odds with UK data protection requirements such as the Data Protection Act 2018 and ICO guidance, potentially resulting in fines or audit issues.
A typical scenario: How a 50-staff business handles updates
Consider a UK-based marketing agency with around 50 employees using on-premise servers for file storage and email. Their IT partner schedules monthly maintenance windows to apply security patches and critical updates, prioritising urgent fixes as soon as they are released. This approach minimises disruption and ensures the servers remain secure. The IT partner also monitors update releases and tests them in a controlled environment before deployment, reducing the risk of software conflicts or downtime.
Practical checklist: What you can do now
- Ask your IT provider: How quickly do you apply security updates to our servers? Do you have a patch management policy?
- Review your service agreement: Does it include regular patching and monitoring? Are emergency updates covered?
- Check update schedules: Are updates applied during low-usage hours to reduce impact on staff?
- Verify backup routines: Are recent backups available before updates, so you can restore if needed?
- Confirm logging and monitoring: Is there a system to detect failed updates or unusual activity post-patching?
- Ensure multi-factor authentication (MFA): Is MFA enabled on administrative access to servers?
- Maintain an asset inventory: Know which servers and software versions are in use to prioritise updates.
Regularly updating server software is a critical part of maintaining your business's cybersecurity and operational resilience. If you're unsure about your current patching practices or want to improve your approach, consider discussing your needs with a trusted managed IT provider or IT advisor. They can help you establish a clear update schedule, implement monitoring tools, and align your processes with UK security standards, giving you greater confidence in your IT infrastructure.
