What Is Ringfencing? The Hidden Layer of Cybersecurity You’re Missing

Most businesses think stopping malware is all about blocking what gets in. But what about what happens after something is allowed to run?

Even approved applications can be dangerous when they interact with other tools, access your data, or connect to the internet without control. That’s where ThreatLocker Ringfencing™ comes in.

At Cyber Solutions, we use Ringfencing™ to help clients contain application behavior, reduce risk, and stop attackers from moving laterally once inside.

What Is ThreatLocker Ringfencing™?

Ringfencing is a feature that controls how applications interact with your system and with each other. You can block an application from launching PowerShell, accessing mapped drives, or reaching out to command-and-control servers — even if that app is already allowlisted.

It’s not about whether a program is safe to run. It’s about what it’s allowed to do after it’s running.

‍

Why Ringfencing™ Is Critical to Modern Cybersecurity

• Stops fileless attacks: Prevent programs from launching tools like PowerShell or WMI
• Contains legitimate apps: Keep tools like Excel or Chrome from accessing sensitive files
• Reduces damage from exploited software: If a known application is hijacked, Ringfencing limits its reach
• Limits lateral movement: Block applications from communicating with other devices or services they shouldn’t

By default, most operating systems allow software to interact freely across your environment. Ringfencing replaces that open-door policy with controlled, purpose-built rules.

‍

Examples in the Real World

• Block ransomware from using Word to launch PowerShell scripts
• Prevent web browsers from accessing internal file shares
• Stop IT tools from connecting to the internet unless required
• Keep backup software isolated from everyday user access

These small changes create massive impact. If one tool is compromised, it can no longer be used to move laterally, steal data, or trigger other programs.
