SystemUpdated Control

What does this control check?

The SystemUpdated control verifies that your operating system has all the latest security updates and patches installed. Keeping your system up to date is one of the most important steps you can take to protect your device.

Why is this important?

🛡️

Security Patches

Software updates fix known security vulnerabilities that attackers actively exploit. Running outdated software leaves you exposed to these well-documented threats.

🔒

Data Protection

Security vulnerabilities in outdated systems can allow attackers to steal your data, passwords, and personal information. Updates close these security holes.

✨

New Features

Updates often include improvements to existing security features, better performance, and new protections against emerging threats.
