Ringfencing™

Reduce the chance of a cyberattack by limiting what applications can do, whether it’s interacting with another application, your files, data, or the internet.

What Is Application Containment (Ringfencing™)?

Ringfencing™ controls what applications can do once they are running. Think of Ringfencing™ as a barrier and extra security measure that is actively containing software from stepping outside of its lane. By limiting what software can do, ThreatLocker® Ringfencing™ can reduce the likelihood of an exploit being successful or an attacker weaponizing legitimate tools such as PowerShell.

Ringfencing™ allows you to control how applications can interact with other applications. For example, while both Microsoft Word and PowerShell may be permitted, Ringfencing™ will stop Microsoft Word from being able to call PowerShell, thus preventing an attempted exploit of a vulnerability such as the Follina vulnerability from being successful.

Why Ringfencing™?

Under normal operations, all applications permitted on an endpoint or server can access all data that the operating user can access. This means if the application is compromised, the attacker can use the application to steal or encrypt files.

Attackers can also use fileless malware which runs in the computer's memory, to evade detection by antivirus or EDR that are focused on detecting changes to files or registry keys. These attacks, often called living off the land attacks, leverage native tools and trusted applications to carry out malicious instructions in the background without ever touching the file system.

How Does Ringfencing™ Work?

When you first deploy Ringfencing™, your device will be aligned with the default ThreatLocker® policies. These policies are then automatically applied to a list of known applications such as Microsoft Office, PowerShell, or Zoom.

The aim of the default policies is to provide a baseline level of protection for all endpoints. Each of these policies can easily be manipulated to fit any environment at any time.

Do You Need Ringfencing™?

Ringfencing™ is a valuable strategy to enhance the security of an organization's digital posture. Organizations across any industry can benefit from Ringfencing™ by isolating critical and trusted applications from unintended uses or weaponization, limiting the lateral movement of attackers within their network.

Ringfencing™ helps protect sensitive data, such as customer information, intellectual property, and financial data, from unauthorized access or data breaches.

Use Ringfencing™ to:

  • Protect your important data: Whether that be financial information, customer information, or your invaluable intellectual property.
  • Keep bad actors at bay: Prevent hackers and cybercriminals from accessing your data.
  • Control access: Control what your applications have access to and how they can interact within your environment.

Preventing Software Exploitation with Application Containment

Ringfencing™ was able to foil a number of attacks that were not stopped by traditional EDR. The 2020 SolarWinds Orion attack was foiled by Ringfencing™. See how Ringfencing™ allows you to remove file access permissions for applications that do not need access and even remove network or registry permissions.
