ThreatLocker Enforces Zero Trust With Strict Application Control (Sponsored)

Why It Matters

By enforcing zero‑trust at the application layer, ThreatLocker gives organizations a practical way to eliminate hidden software risks, lowering breach likelihood and operational overhead.

Key Takeaways

• Shift from default‑allow to default‑deny security paradigm across endpoints, cloud, and network
• Combine allow‑listing with ring‑fencing to restrict app actions
• Kernel‑level agent provides real‑time control and full visibility
• ThreatLocker maintains 14,000+ app definitions, ensuring updates never break policies
• Granular network and cloud policies prevent living‑off‑the‑land exploits

Summary

The Packet Protector podcast, sponsored by ThreatLocker, spotlights the company’s zero‑trust platform that moves security from a “trust‑but‑verify” model to a “deny‑by‑default, permit‑by‑exception” approach.

Rob Allen explains that ThreatLocker combines traditional allow‑listing with “ring‑fencing,” which not only decides which binaries may execute but also restricts what those binaries can do—such as limiting PowerShell’s internet access or preventing Office from launching a command prompt. A kernel‑level agent enforces these policies in real time while a companion service handles processing and reporting.

Allen likens the solution to the iPhone’s App Store gatekeeper, noting that only approved software can run on Windows, macOS, or Linux endpoints. He cites concrete examples: blocking rogue remote‑access tools like TeamViewer, curbing PowerShell’s ability to download payloads, and automatically cataloguing every application on a machine for instant visibility.

For enterprises, this granular control shrinks the attack surface, mitigates living‑off‑the‑land techniques, and simplifies compliance by providing continuous audit trails. The managed definition service, covering over 14,000 applications, ensures updates never break policies, allowing security teams to focus on business‑critical exceptions rather than endless whitelist maintenance.

Original Description

ThreatLocker takes an opinionated approach to Zero Trust. The company, our sponsor for today's episode, starts with application control. It uses endpoint software that runs on PCs and servers to allow or deny applications to run. It can also monitor and control the behavior of allowed applications.

ThreatLocker has extended its platform to include network and cloud access controls and Privileged Access Management (PAM). JJ and Drew talk with Rob Allen, Chief Product Officer at ThreatLocker, to understand how the company's products work, why ThreatLocker puts application control at the heart of its threat defense approach, how it differentiates from other zero trust solutions, and more.
