We all have a natural resistance to change. When a familiar app or platform updates its interface, the instinct is often to groan and wish things had stayed the same. But when it comes to software updates in a business environment, that resistance can carry a serious cost — one that cybercriminals are actively counting on.

Updates Aren’t Just About New Features

 

 

It’s a common misconception that software updates are primarily about adding new functionality or changing the way something looks. In reality, the majority of critical updates — whether for your operating system, business applications, or website platform — exist for one reason: to close a security vulnerability before it can be exploited.

Cybercriminals actively scan the internet for businesses running outdated software. The moment a vulnerability is publicly disclosed, attackers begin targeting any system that hasn’t yet applied the patch. This window between a vulnerability being discovered and a business applying the fix is known as the patch gap — and it’s one of the most common entry points for ransomware, data breaches, and malware attacks on UK businesses.

In 2026, with cyber threats evolving at machine speed, leaving software unpatched is no longer just a technical oversight — it’s a business risk.

What Needs to Be Kept Up to Date?

 

 

For most Essex businesses, the software estate that needs regular patching is broader than many people realise:

• Operating systems — Windows 10 and Windows 11 devices receive regular security patches from Microsoft that should be applied promptly across all endpoints
• Microsoft 365 applications — Word, Excel, Outlook, Teams, and other Microsoft 365 apps receive frequent updates that address both security vulnerabilities and performance issues
• Web browsers — Chrome, Edge, and Firefox are common attack vectors if left unpatched
• Website platforms — If your business runs a WordPress or similar CMS-based website, keeping the core platform, themes, and plugins updated is essential. Outdated WordPress installations remain one of the most commonly exploited entry points for website defacement and data theft
• Mobile devices and apps — Company smartphones and tablets running outdated operating systems or apps present real vulnerabilities, particularly where business email and cloud data are accessed
• Firewalls and network equipment — Routers, firewalls, and managed switches all have firmware that requires regular updates, especially in business environments

The Risk of Doing Nothing

 

 

The consequences of running unpatched software go well beyond the occasional system hiccup. For UK businesses, the risks include:

• Ransomware attacks — Cybercriminals encrypt your data and demand payment for its return. Unpatched systems are a primary entry point
• Data breaches — A breach involving customer or employee data can trigger significant fines under UK GDPR
• Business downtime — A successful cyberattack can bring operations to a standstill, sometimes for days
• Reputational damage — Customers and partners lose confidence in businesses that suffer avoidable security incidents
