The WHY behind this solution

Even trusted applications can be used against you.

All permitted applications on an endpoint inherit the same level of access the user has, meaning they can reach other apps, files, the network, and the registry. If one of those trusted apps is compromised, it can be weaponized to steal data, encrypt files, abuse built-in tools, and connect to malicious IPs. Take the Follina exploit: a malicious Word doc calls PowerShell, and just like that, your trusted app launches a full-blown cyberattack.

What if you could surround those apps with a protective barrier and limit how they interact to reduce potential vectors of attack? That's exactly what ThreatLocker Ringfencing does-acting as your first line of defense against attempts to hijack your trusted applications and turn them into vicious attack weapons against your own business.

What is ThreatLocker Ringfencing™?

Ringfencing™ is your application containment strategy. It allows trusted apps to run-but only lets them interact with the specific files, registry keys, network resources, or other applications they actually need. It adds a critical layer of control-ensuring apps can only do what they're supposed to do, and nothing more.

Here's how it works:

1. Deploy with default protections
Ringfencing applies baseline policies immediately for common apps like Microsoft Office, PowerShell, and Zoom. No setup needed. Instant security from the start.

2. Customize with high granularity
Need PowerShell to run, but not reach the internet? Done. Want Word to open documents, but never launch another app? Easy. You define the rules to restrict the apps to behave exactly how you want them to.

The results?

Less risk. Tighter control. No more application overreach.

Ringfencing takes the control of your environment to a new level, enforcing strict boundaries that attackers can't bypass. Even if they sneak in, they hit a wall. The ring holds. The attack stops.
