Software and Network Patching — Why It Matters

Back to Resources

Patching might not sound exciting, but it's one of the most important things you can do to keep your business secure and stable.

Every software product — whether it's your operating system, your web browser, your accounting package or network firmware — contains code. That code sometimes has bugs or vulnerabilities that attackers can exploit. When vendors discover these, they release patches: updates that fix the problem.

Why patching matters

1. Cyber security protection

Most cyber attacks exploit known vulnerabilities. These are problems that have already been discovered and published — and for which patches already exist. If one of your devices hasn't been patched, an attacker can walk straight through that door.

2. Network stability

Patches also fix non-security bugs that can cause crashes, data corruption, performance issues or compatibility problems. Keeping software up to date reduces unexpected downtime.

3. Compliance obligations

Standards like ISO 27001, PCI DSS, GDPR and industry regulations often require documented patching processes. Unpatched systems can lead to audit findings or legal exposure.

4. Performance and features

Not all patches are about fixing problems. Some include performance improvements, battery life enhancements or new features that make your team more productive.

A managed approach

Randomly updating software when someone remembers isn't enough. You need a structured process:

• Inventory your software and devices — know what you have
• Monitor vendor patch releases — especially Windows, Office, servers and firewalls
• Prioritise critical updates — the most security-relevant patches go first
• Test before widespread deployment — avoid unintended side effects
• Automate where possible — reduces human error and saves time
• Report and review — know what's been applied and what's pending

Network devices matter too

It's not just servers and PCs. Firewalls, switches, wireless controllers and printers all run software that sometimes needs updating. Leaving these unpatched creates security blind spots.

The bottom line

Effective patching is one of the simplest yet highest-impact elements of a strong IT programme. It prevents breaches, improves reliability and forms a core part of responsible IT management. Patching isn't optional — it's essential.
