A practical look at ThreatLocker's learning curve and custom pricing model, and what to look for in an alternative built for faster time-to-policy.
ThreatLocker has built a strong reputation in the MSP channel around deny-by-default application allowlisting, and its Ringfencing feature, which restricts what an already-approved application is allowed to do rather than just whether it can run, is a genuinely useful second layer of containment. It's also a platform that comes with real tradeoffs worth understanding before you commit a client base to it.
ThreatLocker's core positioning is deny-by-default application control paired with Ringfencing, Elevation Control, and Storage Control, aimed at stopping threats before execution rather than detecting them afterward. For MSPs specifically focused on a strict Zero Trust posture and willing to invest the setup time, that combination genuinely reduces attack surface in a way blocklist-only tools don't.
No published pricing. ThreatLocker runs on a custom quote model based on endpoint count, deployment type, and which modules you add on top of the core allowlisting and Ringfencing bundle. That makes it difficult for an MSP to quote a prospect quickly or budget predictably without going through a sales cycle first.
A real learning curve. Ringfencing specifically requires understanding how your applications interact with each other before you can write effective policies, and that upfront mapping work is commonly cited as the platform's steepest onboarding cost.
Module sprawl. The platform spans allowlisting, Ringfencing, Zero Trust Network Access, Privileged Access Management, and a managed detection and response add-on. That's appealing if you want one vendor for everything, but it also means the core application control functionality is bundled inside a much larger (and more expensive) platform decision.
Deny-by-default only. ThreatLocker's architecture leads with default-deny across the board. That's the right call for a security-first MSP, but teams that want the flexibility to run a lighter block list on lower-risk device groups and reserve default-deny for high-risk ones don't get that hybrid choice out of the box.
No native IT asset management. Application control decisions are only as good as the software inventory behind them. ThreatLocker doesn't include IT asset management, so teams typically run a separate inventory and licensing tool alongside it.
Hybrid enforcement per group, so you're not forced into default-deny everywhere when a targeted block list would serve a lower-risk device group just as well.
Predictable, transparent pricing you can quote a client without a custom sales process.
A shorter path to a working policy, rule types (product, vendor, executable, hash, path) that don't require mapping application-to-application interactions before you get basic protection live.
Application control unified with software inventory, so your allowlist or block list baseline is built from real data you already have, not a second system you have to maintain in parallel.
Graduated enforcement, audit, warn, and block modes you can move through in stages rather than a single deny-by-default posture from day one.
Zecurit's Application Control gives you the same core outcome, unauthorized software doesn't run, without requiring a full application-interaction mapping exercise before you see value. Administrators create an Application Group, choose Block List or Allow List as the Access Type, tag a Risk Level, and associate rules across five types (Product/Software, Vendor, Executable, File Hash, Folder Path), either individually, from an existing rule library, or via bulk CSV import.
Enforcement moves through the same graduated stages covered in our application control best practices guide: Audit Only to build a baseline, Notify Only to catch false positives without disruption, then Block & Notify or Block Execution once you're confident in the policy. That phased path gets a new client to a working, defensible policy faster than a deny-by-default architecture that requires deep application-behavior mapping before enforcement can safely go live.
Because Application Control sits inside the same platform as IT asset management and software inventory, your policy baseline is built from data you're already collecting, not a separate discovery process. And because Zecurit is priced and licensed as part of a unified endpoint management platform, MSPs get a quote they can plan around instead of a custom, module-by-module sales cycle. See the full Application Control overview or compare across all leading application control platforms, including where ThreatLocker, Zecurit, and native Windows tools each fit.
No application-interaction mapping required to get started. Build an Application Group, set your Access Type, and move from Audit Only to full enforcement in stages, with pricing you can quote without a custom sales cycle.

Zecurit's Application Control focuses on whether an application is allowed to run at all, allowlisting and blocklisting by product, vendor, executable, hash, or path. Restricting what an already-approved application can do once running is a separate layer, typically handled alongside Endpoint Privilege Management rather than as part of application control itself.
There's no automatic policy import between platforms with different rule structures, but the process is more manageable than it sounds: export your current allowlist by application and publisher, then rebuild it using product/vendor and executable rules, which is typically the majority of any allowlist regardless of vendor.
It's the stronger posture for high-risk endpoints, which is why we recommend it for finance, engineering, and regulated-data device groups in our best practices guide. For lower-risk groups, a well-maintained block list targeting known prohibited applications delivers most of the security benefit with meaningfully less ongoing maintenance overhead.
