Managed ThreatLocker Ringfencing - control what each approved application is allowed to do, what files it can touch, what it can talk to on the network, and which other apps it can launch.
Allowlisting stops untrusted apps from running. Ringfencing stops trusted apps from being abused. The vast majority of modern attacks live off the land - PowerShell spawning a payload, Word launching a macro that calls Excel, a signed binary executing a hidden script. Ringfencing breaks those paths.
We define what every approved app can and cannot do: which other processes it may launch, which files and folders it may touch, and which network destinations it may reach.
Everything in this service. Nothing buried in fine print.

[ Why ringfencing ]
Living-off-the-land attacks die at the boundary
Most ransomware does not arrive as ransomware. It arrives as a Word doc that launches PowerShell that downloads the payload. Ringfencing breaks that chain by denying the unusual process-to-process behavior, even though every individual binary involved is trusted and signed.
[ Real examples ]
What we typically lock down
Office is not allowed to launch PowerShell. PowerShell is not allowed to reach the internet. Browsers are not allowed to write to system folders. RDP clients are not allowed to launch credential dumpers. The result is that the same attacker tradecraft that defeats EDR is broken cleanly.
[ Industry use cases ]
How different industries put this service to work
Every regulated and growth-stage business we support has a slightly different reason for engaging this service. The common thread is that the risk, downtime, or compliance cost of doing nothing is now bigger than the cost of a specialized partner.

[ Buyer checklist ]
What good looks like when you evaluate providers
Not every provider that lists this service on their website actually delivers it well. Use the checklist below when you shortlist partners so you can compare apples to apples and avoid the two most common traps: a low sticker price that hides scope gaps, and a polished sales cycle backed by an offshore delivery team you never meet.
If a prospective provider cannot answer these questions plainly and in writing, treat that as a signal. The right partner will welcome the scrutiny.
