Secure Your Enterprise with ThreatLocker Zero Trust Controls
ThreatLocker provides a Zero Trust endpoint security platform that uses application whitelisting and ringfencing to give IT professionals total control over their data.
Overview
ThreatLocker is a leading provider of endpoint security technologies that focus on a Zero Trust approach to cybersecurity. Founded in 2017 and headquartered in Orlando, Florida, the company has rapidly ascended in the security market by addressing the fundamental weaknesses of detection-based security models. ThreatLocker’s mission is to provide organizations with total control over their endpoints, ensuring that no unapproved software can execute and no unauthorized data access can occur.
The company primarily serves small to medium-sized enterprises (SMEs) and managed service providers (MSPs) who require enterprise-grade security that is scalable and manageable. Their platform is designed to protect against ransomware, malware, and unauthorized data access by implementing a "Default Deny" posture. In an era where cyber threats evolve faster than signature-based or even AI-based detection tools can keep up, ThreatLocker provides a proactive shield.
ThreatLocker’s market presence is particularly strong in the MSP channel, where they have become a standard-bearer for Zero Trust implementation. Their suite of tools—including Application Allowlisting, Ringfencing, Storage Control, Elevation Control, and Network Control—provides a multi-layered defense-in-depth strategy. By shifting the burden of security from "detecting the bad" to "allowing only the good," ThreatLocker simplifies the security stack while significantly increasing the difficulty for attackers to gain a foothold in a protected environment.
Positioning
ThreatLocker positions itself as the "Zero Trust" authority for the endpoint. In a crowded marketplace filled with EDR, XDR, and MDR vendors who promise to detect threats using artificial intelligence and machine learning, ThreatLocker’s messaging is refreshingly contrarian: "Stop trying to detect, and start denying."
Their competitive positioning strategy focuses on the "Detection Gap"—the period between a new threat's release and its identification by security vendors. ThreatLocker positions its products as the solution to this gap, offering 100% protection against unknown threats because those threats are, by definition, not on the "allow" list.
Targeting IT professionals and MSPs, ThreatLocker differentiates itself by emphasizing control and visibility. Their brand is built on being the "strongest link" in a security chain, often positioning their platform as a necessary foundational layer that works alongside traditional tools but provides the ultimate safety net. They successfully bridge the gap between high-level security requirements (like those found in NIST or CIS frameworks) and practical, day-to-day IT operations.
Differentiation
The ThreatLocker product suite stands out by moving beyond traditional antivirus and EDR (Endpoint Detection and Response) through a default-deny architecture. While most security tools try to identify "bad" files, ThreatLocker assumes everything is untrusted until proven otherwise.
Key technical differentiators include:
- Application Allowlisting: This is the core of the platform, ensuring that only pre-approved applications, scripts, and libraries can execute. This effectively neutralizes zero-day exploits and ransomware that have not yet been categorized as malicious.
- Ringfencing™: This unique capability goes a level deeper than allowlisting. It controls what an authorized application can do once it is running. For example, it can prevent Microsoft Word from accessing your files or launching PowerShell, even though Word itself is a trusted application.
- Storage Control: This provides granular policy-driven access to local folders, network shares, and external devices, ensuring that data cannot be exfiltrated or encrypted by unauthorized processes.
- Network Access Control (NAC): ThreatLocker extends its Zero Trust model to the network layer, allowing organizations to control traffic based on the identity of the computer and the application, rather than just IP addresses.
- Elevation Control: This allows users to run specific applications with administrative privileges without giving them full local admin rights, adhering to the principle of least privilege.
Ideal Customer Profile
ThreatLocker is designed for organizations that have moved beyond basic security needs and require granular control over their environment.
- Company Size: Small-to-Mid-Market (50+ employees) up to Large Enterprises. It is particularly popular in the MSP (Managed Service Provider) space.
- Industries: Legal, Healthcare, Finance, Government Contracting (CMMC), Manufacturing, and any sector handling sensitive PII or intellectual property.
- Technical Maturity: Moderate to High. The organization should have a centralized way to manage endpoints (like RMM, Intune, or AD) and a desire to move from reactive to proactive security.
- Budget: Organizations that prioritize "uptime" and "breach prevention" over the lowest-cost security tool. It is for those who view a ransomware event as a business-ending risk.
- Team Composition: Best suited for teams with at least one dedicated IT administrator or an outsourced MSP who can manage the initial "learning mode" and ongoing policy approvals.
Best Fit
ThreatLocker excels in several critical scenarios where traditional antivirus and EDR solutions fall short:
- Zero-Trust Enforcement: It is the premier choice for organizations moving away from "detect and respond" to a "deny by default" posture. If your goal is to ensure that only pre-approved applications can run, ThreatLocker is the market leader.
- Ransomware Mitigation: Because ransomware relies on executing unapproved binaries or using trusted tools (like PowerShell) in malicious ways, ThreatLocker’s Ringfencing™ is uniquely suited to stop these attacks by limiting what applications can do once they are running.
- Compliance-Driven Environments: For businesses governed by HIPAA, PCI-DSS, or CMMC, ThreatLocker provides the granular auditing and control over data access and software execution required to meet stringent regulatory checkboxes.
- Managed Service Providers (MSPs): ThreatLocker is built with multi-tenancy at its core, making it an ideal fit for MSPs who need to manage security postures across dozens or hundreds of different client environments from a single pane of glass.
Offerings
ThreatLocker offers a modular platform, allowing organizations to scale their security posture:
- ThreatLocker Ops: A community-driven detection and response tool that allows admins to create custom alerts and automated actions based on system events (e.g., "Alert me if a user plugs in a USB and copies more than 50 files").
- Allowlisting (Core): The foundational product for controlling executable files, scripts, and libraries.
- Ringfencing™: Adds the ability to define boundaries for applications, restricting their interaction with files, the network, and other apps.
- Storage Control: Manages access to local and network drives, as well as external storage (USBs).
- Elevation Control: A Just-In-Time (JIT) elevation tool that solves the "Local Admin" problem by allowing specific apps to run as admin without compromising the user account.
- Network Control: A managed endpoint firewall to secure the perimeter at the device level, regardless of location.

Introduction
Welcome to the comprehensive evaluation guide for ThreatLocker, a leader in endpoint security through Zero Trust controls. As the threat landscape shifts from known malware to "living-off-the-land" attacks and zero-day exploits, traditional reactive security measures often prove insufficient. ThreatLocker takes a proactive approach by giving organizations total control over what software can run on their endpoints.
This guide is designed for IT directors, CISOs, and MSP owners who are considering moving beyond traditional antivirus to a "Default Deny" security posture. You will learn about ThreatLocker's core pillars—Application Allowlisting, Ringfencing™, and Storage Control—and how they integrate into your existing infrastructure. By the end of this guide, you will have the technical and operational insights necessary to determine if ThreatLocker is the right fit for your organization’s security maturity and compliance goals.
Key Features
ThreatLocker provides a suite of controls that go beyond traditional endpoint protection:
- Application Allowlisting: The core of the platform. It prevents any unapproved software, scripts, or libraries from executing, effectively stopping zero-day threats and unauthorized "Shadow IT."
- Ringfencing™: This unique feature controls what applications can do after they are launched. It prevents apps from interacting with each other, accessing your files, or communicating with the internet unless explicitly permitted. (e.g., stopping Word from launching PowerShell).
- Storage Control: Provides granular control over data access. You can restrict access to local folders, network shares, and USB devices based on the user or the specific application being used.
- Network Control: A dynamic firewall that allows you to control inbound traffic to your endpoints based on IP address or keyword, providing an extra layer of protection for remote workers.
- Elevation Control: Allows users to run specific applications with administrative privileges without giving them full local admin rights, adhering to the Principle of Least Privilege (PoLP).
- Cyber Hero Support: Real-time access to ThreatLocker’s security engineers directly through the portal, typically responding in under 60 seconds to help with policy decisions.
Use Cases
ThreatLocker is used across various industries to solve specific security gaps:
- Stopping "Fileless" Malware: A law firm uses Ringfencing to prevent Microsoft Outlook from ever launching PowerShell or Command Prompt. Even if a user clicks a malicious attachment, the "living-off-the-land" attack is blocked at the source.
- Securing Legacy Systems: A manufacturing facility runs specialized software on Windows 7 machines that can no longer receive security patches. ThreatLocker "locks down" these machines so that only the specific manufacturing app can run, rendering unpatched vulnerabilities unexploitable.
- Eliminating Local Admin Rights: A healthcare provider uses Elevation Control to let nurses update a specific medical charting app without giving them full administrator passwords, reducing the risk of accidental malware installation.
- Protecting Sensitive IP: A high-tech engineering firm uses Storage Control to ensure that only their CAD software can access the "Blueprints" folder on the file server, preventing a compromised browser or email client from exfiltrating data.
Pricing Models
ThreatLocker typically uses a subscription-based pricing model tailored to the size of the organization or the MSP's client base:
- Per-Endpoint Licensing: Pricing is generally calculated per agent (workstation or server) per month.
- Tiered Bundling: Features like Storage Control, Network Control, and Elevation Control may be sold as add-ons to the core Allowlisting and Ringfencing package or bundled into "Pro" or "Enterprise" tiers.
- MSP Pricing: Special volume-based pricing is available for Managed Service Providers, allowing them to scale across multiple clients with aggregate billing.
- No Hidden Fees: Implementation support and access to the "Cyber Hero" team are typically included in the subscription, though dedicated professional services for complex migrations may incur extra costs.
- Contract Terms: Options usually range from monthly commitments (common for MSPs) to multi-year enterprise agreements for larger discounts.
Technical Requirements
The ThreatLocker solution is lightweight but requires the following environment:
- Operating Systems: Windows (7, 8, 10, 11; Server 2008 R2 and up) and macOS. Support for Linux is in development/limited release.
- Hardware: Minimal impact; the agent typically consumes less than 1% CPU and roughly 50-100MB of RAM.
- Network: Outbound access to ThreatLocker’s cloud controllers via HTTPS (Port 443). No inbound ports need to be opened on the local firewall.
- Compatibility: Designed to run alongside existing Antivirus or EDR solutions. It does not replace these but adds a layer of Zero Trust control.
- Agent Deployment: Requires administrative rights for installation; supports MSI deployment via standard software distribution tools.
Business Requirements
To successfully deploy ThreatLocker, an organization must meet several operational prerequisites:
- Process Maturity: Organizations must be prepared to move away from a "shadow IT" culture. There must be a defined process for how employees request new software and how IT approves those requests.
- Staff Allocation: While ThreatLocker offers a managed service (Cyber Hero Team), internal IT needs to designate a lead for policy ownership. During the initial "Learning Mode" phase, this individual will need to spend time reviewing discovered applications.
- Change Management: Clear communication with end-users is vital. Users need to understand that they can no longer install unapproved software and must know the workflow for requesting exceptions to avoid frustration.
- Stakeholder Buy-in: Executive leadership must support the "Deny by Default" philosophy, as it prioritizes security over absolute user autonomy.
Implementation Timeline
A typical ThreatLocker implementation follows a structured path to ensure zero business disruption:
- Phase 1: Discovery & Agent Deployment (Days 1-3): Deploying the agent in "Learning Mode" across the fleet. This is typically done via RMM or GPO.
- Phase 2: Learning Mode (1-2 Weeks): The agent monitors all activity without blocking anything. This creates a baseline of every application, script, and library currently used in the environment.
- Phase 3: Policy Review & Hardening (Week 3): IT admins review the learned data and create "Allow" policies for legitimate business tools. ThreatLocker’s "Built-in" definitions simplify this for common apps like Office or Zoom.
- Phase 4: Locking (Week 4): The environment is moved to "Secured" status. Unapproved applications are now blocked.
- Phase 5: Refinement (Ongoing): Fine-tuning Ringfencing rules and storage control policies based on user feedback and evolving threats.
Support Options
ThreatLocker is highly regarded for its "Cyber Hero" support model:
- Instant Chat Support: Available 24/7/365 directly within the management console. Response times are famously fast, often under 60 seconds.
