Citadel / Controls / MissingApplications

MissingApplications Control

What does this control check?

The MissingApplications control verifies that all required applications for your organization are installed on your computer. The specific list of required applications is configured by your IT team based on security requirements, your role, and business needs.

Important: Citadel will tell you which specific application(s) need to be installed. Required applications are typically essential security tools (antivirus, VPN, backup software), mandatory business applications, or compliance tools that protect both you and the organization. Operating without these applications leaves your device vulnerable to security threats and may prevent you from securely accessing company resources.

Why is this important?

🛡️

Essential Protection

Required applications often include critical security tools like antivirus software, endpoint protection, or VPN clients that are necessary to protect your device from threats.

🔐

Secure Access

Some required applications are necessary to securely connect to company systems, encrypt communications, or authenticate properly. Without them, you may be unable to work securely.

⚖️

Compliance

Regulations and security frameworks often mandate specific tools and controls. Required applications ensure your device meets these compliance requirements.
