Update Your Software—It’s the Easiest Win in Cybersecurity

Written by Envision IT Pressroom | Oct 19, 2025 12:00:00 PM

If cybersecurity were a game, software updates would be the cheat code. Yet many users delay them, leaving systems exposed. At Envision IT, we call updates “digital hygiene”—simple, routine, and essential.

Why Updates Matter: Updates patch known vulnerabilities. Attackers often exploit outdated software—sometimes within hours of a flaw being disclosed.

Behind the Breach: Microsoft SharePoint “ToolShell” Exploits (2025)
In 2025, attackers exploited a known vulnerability—ToolShell—in unpatched on-premises Microsoft SharePoint servers. Despite Microsoft having released patches, many organizations delayed applying them. As a result, over 400 systems were compromised, including those belonging to U.S. government agencies and the Department of Energy.
This breach is a stark reminder that delaying updates can have national-level consequences. The fix was available—but unpatched systems remained vulnerable, giving attackers an easy in.

What to Update:

  • Operating systems
  • Browsers and plugins
  • Mobile apps
  • Security tools

Make It Easy:

  • Enable automatic updates where possible.
  • Schedule update windows to minimize disruption.
  • Use centralized patch management tools.

For IT Leaders: Implement patch management policies. Use tools like WSUS or Intune. Track update compliance and prioritize critical patches to help prevent major incidents. Real-time dashboards and automation streamline the process.

Updating software is one of the easiest cybersecurity wins. Don’t ignore it—embrace it.
