Zero Trust Security

What is ThreatLocker Application Control?

ThreatLocker is a zero-trust application control platform that fundamentally changes how your business handles software security. Instead of trying to detect and block known threats (the traditional antivirus approach), ThreatLocker operates on a simple principle: deny everything by default, allow only what's explicitly approved.

This approach-called allowlisting-means ransomware, malware, and unauthorised software simply cannot run on your systems, even if your antivirus has never seen that specific threat before. It's the difference between maintaining a blocklist of millions of known threats versus maintaining a much shorter list of approved applications your business actually uses.

Milnsbridge deploys and manages ThreatLocker as part of our managed IT security stack. It's a core component of implementing the Australian Government's Essential Eight security controls-specifically Application Control, which is one of the most effective mitigations against malware.

How It Works

ThreatLocker's Multi-Layered Protection

Application Allowlisting

Only approved applications can run. Everything else is blocked by default. New software-even zero-day malware-simply cannot execute without explicit approval.

Ringfencing

Limits what approved applications can do. Even if an attacker exploits a vulnerability in allowed software, ThreatLocker prevents it from accessing sensitive files, registry keys, or system resources.

Elevation Control

Controls which applications can run with administrator privileges. Users don't need local admin rights-ThreatLocker can elevate specific approved apps when needed.

Network Control

Restricts which applications can access the network and where they can connect. Prevents data exfiltration and command-and-control communications.

Why It Matters

Protection That Antivirus Can't Match

Traditional security relies on recognising threats. Antivirus and EDR solutions like SentinelOne (which we also deploy) detect and respond to known attack patterns. They're essential-but they're reactive. They need to know about a threat to stop it.

ThreatLocker works differently. It doesn't care whether software is malicious-it only cares whether it's approved. This stops:

  • Zero-day ransomware that your antivirus has never seen
  • Fileless malware that runs in memory without dropping files
  • Supply chain attacks where legitimate software is compromised
  • Insider threats from employees running unauthorised tools
  • Living-off-the-land attacks using built-in system tools maliciously

We deploy ThreatLocker alongside SentinelOne-layered security that catches threats two ways. It's a key reason our clients don't make ransomware headlines.

Deployment & Management

How Milnsbridge Implements ThreatLocker

Application control requires proper deployment and ongoing management. We handle the entire process:

Initial Learning Mode

We deploy ThreatLocker in learning mode first, cataloguing all applications your business uses. No disruption while we build your baseline.

Policy Configuration

We build allow policies for your approved software, configure ringfencing rules, and set up elevation controls tailored to your workflows.

Ongoing Management

When you need new software approved, we review and approve it quickly. We monitor blocked application requests and adjust policies as your business evolves.

Part of the Cyber Uplift Program

ThreatLocker is deployed as part of our structured cyber security uplift program. We scope it based on your environment and compliance requirements, with pricing provided as part of your uplift roadmap.

FAQ

Common Questions About ThreatLocker

Won't allowlisting block legitimate software I need?

Not if it's set up correctly. We deploy ThreatLocker in learning mode first, capturing everything your business uses. When you need new software approved, we review and approve it quickly-usually within minutes during business hours.

Why do I need ThreatLocker if I already have antivirus?

Antivirus (like SentinelOne) detects known threats. ThreatLocker blocks unknown threats. They work together-SentinelOne catches what it recognises, ThreatLocker stops everything else. Layered security is always stronger.

What is the Essential Eight and why does application control matter?

The Essential Eight is the Australian Government's recommended cybersecurity framework. Application Control is one of the eight strategies-and the Australian Signals Directorate rates it as one of the most effective mitigations against malware.

How much does ThreatLocker cost?

ThreatLocker is available as part of our cyber security uplift program and is scoped to your environment. It can be added to Core ($89) or Growth ($99) plans as an optional add-on. Talk to us for specific pricing.

Does ThreatLocker slow down computers?

No. ThreatLocker's agent is lightweight. It runs at the kernel level and has minimal performance impact. Users don't notice it's there-until it blocks something malicious.
