Why Trust Our Software Reviews
ThreatLocker Overview
ThreatLocker is a Zero Trust endpoint security platform that combines application allowlisting, RingFencing, Elevation Control, Storage Control, and Network Control to tightly control what can run, what it can talk to, and what it can touch across your environment. It is designed primarily for MSPs and midmarket enterprises that want to move from reactive “detect and respond” tools to a default-deny posture, while still managing policies centrally at scale.
Expect strong prevention against ransomware and unauthorized apps through its default-deny model, paired with central visibility into policy enforcement across your endpoints. You’ll handle granular controls over executions, network connections, and data access via a unified cloud portal. Initial tuning requires time as the platform learns your environment, but it delivers precise blocking once configured.
pros
-
Detailed logging supports compliance, audits, and forensic investigations.
-
Granular control over applications, storage, and network access.
-
Delivers strong prevention against ransomware and zero-days.
cons
-
End-user friction arises from strict controls that block routine software installs.
-
Not a set-and-forget security solution for most environments.
-
Steep initial learning curve and tuning period, requires upfront policy work to avoid blocking legitimate apps.
Is ThreatLocker Right For Your Needs?
Who Would be a Good Fit for ThreatLocker?
ThreatLocker suits MSPs and security-conscious teams ready to embrace a true default-deny Zero Trust model, especially those tired of alert fatigue from detection tools and seeking granular prevention across endpoints and servers. You’ll find it ideal if your organization values centralized policy management, strong ransomware blocking, and compliance needs like controlling USBs or admin elevations without handing out local admin rights.
-
Remote/Hybrid Workforces
Dynamic network ACLs secure traveling endpoints by whitelisting specific IPs or keywords without VPN overhead.

Who Would be a Bad Fit for ThreatLocker?
ThreatLocker isn’t the right choice if you’re seeking a quick-deploy detection tool or lack the resources for ongoing policy tuning, as its strict default-deny model demands upfront investment in allowlisting and can disrupt workflows during initial rollout. Teams needing broad app compatibility without customization or those prioritizing minimal end-user impact over maximum prevention will find the operational overhead, alert noise, and helpdesk tickets outweigh the benefits.
-
Teams Wanting Hands-Off Security
Ongoing maintenance of policies and responses to learning-mode alerts demands active admin involvement.
-
Enterprises With Heavy Legacy App Ecosystems
Outdated or custom software often fails with whitelisting without extensive vendor coordination and testing.
-
Budget-Constrained SMBs
Modular pricing stacks up for full features, exceeding simple antivirus budgets without delivering detection alerts.
-
Organizations Avoiding Change Management
The shift from “allow by default” generates friction and requires user training on blocked actions.
-
Highly Dynamic Dev Environments
Frequent new software deployments clash with rigid allowlisting, creating constant tuning needs and deployment delays.
-
Small Startups With Limited IT Staff
Policy tuning and exception handling require dedicated time that small teams can’t spare without blocking critical business apps.
Our Review Methodology
How We Test & Score Tools
We’ve spent years building, refining, and improving our software testing and scoring system. The rubric is designed to capture the nuances of software selection and what makes a tool effective, focusing on critical aspects of the decision-making process.
Below, you can see exactly how our testing and scoring works across seven criteria. It allows us to provide an unbiased evaluation of the software based on core functionality, standout features, ease of use, onboarding, customer support, integrations, customer reviews, and value for money.
Core Functionality (25% of final scoring)
The starting point of our evaluation is always the core functionality of the tool. Does it have the basic features and functions that a user would expect to see? Are any of those core features locked to higher-tiered pricing plans? At its core, we expect a tool to stand up against the baseline capabilities of its competitors.
Standout Features (25% of final scoring)
Next, we evaluate uncommon standout features that go above and beyond the core functionality typically found in tools of its kind. A high score reflects specialized or unique features that make the product faster, more efficient, or offer additional value to the user.
We also evaluate how easy it is to integrate with other tools typically found in the tech stack to expand the functionality and utility of the software. Tools offering plentiful native integrations, 3rd party connections, and API access to build custom integrations score best.
Ease of Use (10% of final scoring)
We consider how quick and easy it is to execute the tasks defined in the core functionality using the tool. High scoring software is well designed, intuitive to use, offers mobile apps, provides templates, and makes relatively complex tasks seem simple.
Onboarding (10% of final scoring)
We know how important rapid team adoption is for a new platform, so we evaluate how easy it is to learn and use a tool with minimal training. We evaluate how quickly a team member can get set up and start using the tool with no experience. High scoring solutions indicate little or no support is required.
Customer Support (10% of final scoring)
We review how quick and easy it is to get unstuck and find help by phone, live chat, or knowledge base. Tools and companies that provide real-time support score best, while chatbots score worst.
Customer Reviews (10% of final scoring)
Beyond our own testing and evaluation, we consider the net promoter score from current and past customers. We review their likelihood, given the option, to choose the tool again for the core functionality. A high scoring software reflects a high net promoter score from current or past customers.
Value for Money (10% of final scoring)
Lastly, in consideration of all the other criteria, we review the average price of entry level plans against the core features and consider the value of the other evaluation criteria. Software that delivers more, for less, will score higher.
Core Features
Application Allowlisting
Blocks all unapproved executables by default, using learning modes to build tailored allowlists that prevent ransomware and zero-day exploits from running on endpoints.
Ringfencing
Contains approved applications by restricting their access to files, networks, and other processes, stopping lateral movement even if malware executes.
Elevation Control
Manages admin privileges without granting local admin rights, allowing just-in-time elevations for specific apps or tasks via policy-based rules.
Storage Control
Enforces granular policies on USBs, external drives, and file shares to block unauthorized data access, copying, or execution.
Network Control
Applies dynamic access control lists to whitelist approved connections by IP, domain, or keywords, securing endpoints without full VPN reliance.
Unified Policy Portal
Central cloud dashboard deploys and monitors policies across endpoints and servers with real-time visibility and automated reporting.
Standout Features

Ease of Use
ThreatLocker’s cloud portal offers an intuitive interface for policy creation and endpoint monitoring once you’re past the initial learning curve, but expect a steep ramp-up as you tune allowlists and handle exceptions during deployment. While the dashboard provides clear visibility into blocks and enforcements, the granular controls demand time to master, often requiring 2-4 weeks of active management before they run smoothly. End-users typically face minimal daily friction after onboarding.
Onboarding
ThreatLocker provides a structured onboarding process with automated agent deployment via RMM stub installers, followed by a learning mode that observes your environment for 1-2 weeks to build initial allowlists without disruptions. You’ll get access to ThreatLocker University for self-paced video guides and policy templates, plus optional professional services or partner-led deployments for complex rollouts. You will have success with dedicated implementation specialists who assist via screen shares during the critical tuning phase.
