Whether you’re a one-person operation or a growing business with a full team, we’re here to help. Get in touch and let’s talk about what we can do for you.
Most security tools try to stop known bad software. ThreatLocker Allowlisting flips this entirely — only software you've explicitly approved is allowed to run. Everything else is blocked by default, regardless of whether it's been seen before.
ThreatLocker Allowlisting is an application control tool that enforces a default-deny policy on every device — only approved software can execute. It's the most effective way to prevent ransomware, malware, and unauthorised tools from running on your estate.
When you need enterprise-grade endpoint lockdown — typically for clients with sensitive data, regulatory requirements, or a high risk of targeted attack. Included in the Complete Device Security Pack.
Application allowlisting policies, learning mode deployment, managed approval workflow, hash-based and path-based rules, and full audit logging.
Stops ransomware and malware that antivirus misses, gives you complete visibility and control over what software runs in your business, and provides a clear audit trail for compliance.

This is the most common concern — and it’s why we always deploy in learning mode first. We build the approved baseline from your actual environment before any blocking goes live.
Antivirus tries to identify and block known bad software. Allowlisting blocks everything by default and only permits known good software. The philosophical difference is significant — Allowlisting wins against zero-day threats that antivirus hasn’t seen yet.
Through a simple IT request. We approve the application, update the policy, and it’s available. The process adds a day or two but is worth it for the security gain.
No. ThreatLocker is a lightweight agent and the policy evaluation happens in milliseconds — users typically notice no difference.
Yes. ThreatLocker Allowlisting can control script execution — PowerShell, batch files, VBScript — and works with Ringfencing to control what approved applications are allowed to do.
It’s extremely difficult. Ransomware needs to execute to encrypt files — and if it’s not on the approved list, it can’t execute. This is why Allowlisting is considered one of the most effective defences against ransomware.
ThreatLocker is built for SMBs as much as enterprises. The managed learning mode and 24/7 Cyber Hero support make default-deny workable for businesses of all sizes.
ThreatLocker’s own 24/7 support team, available to help with policy queries, approvals, and incidents. It’s included with the platform and gives you an extra layer of expert support.
ThreatLocker’s primary platform is Windows. Speak to us about your device mix and we’ll confirm coverage for your specific estate.
It’s blocked and the event is logged. The user sees a clear notification. If the software is legitimate, they can raise a request through IT support and we’ll review it.
There is nothing more annoying than an IT glitch that stops you working efficiently. However, knowing you have access to immediate attention to the glitch and a solution to it, is very reassuring and that is provided by We Do Your IT. We have so appreciated the availability and response given by the team at We Do Your IT, enabling us to remain a productive firm.
