Peter Clatterbuck explains how ThreatLocker’ s Zero Trust platform helped TLG Peterbilt secure 34 locations following a third-party breach

Founded in 2017, ThreatLocker is a Zero Trust cybersecurity provider whose core offerings combine allowlisting – which blocks untrusted software such as malware – with controls that contain approved applications so they cannot be hijacked and abused by attackers.

“ Our primary line of defence is an allow listing-based application,” explains Peter Clatterbuck, Enterprise Sales Manager at ThreatLocker.“ That’ s really ThreatLocker’ s bread and butter.“ ThreatLocker’ s learning algorithm handles about 95 % of the legwork of building an allowlist. It runs on every agent.”

The platform maintains roughly 15,000 built-in business applications, removing the risk of unnecessary blocks caused by hash updates or new certificates. Its proprietary ringfencing technology governs how approved applications interact, stopping tools such as Microsoft Office reaching a command prompt or PowerShell. ThreatLocker’ s wider platform also spans data loss prevention, privileged access management, endpoint detection and response, and Zero Trust network and cloud access tools.

Why TLG Peterbilt chose ThreatLocker

Threatlocker has helped haulage giant TLG Peterbilt lock down its IT environment across dozens of sites. TLG Peterbilt’ s move to ThreatLocker was triggered by a third-party vendor breach roughly two years ago, which left unknown software running across its network. Peter says the learning mode proved decisive in restoring visibility:“ It catalogues every application running in the environment. That was the company’ s biggest concern – what was unknown, and what might have slipped through.”

Establishing a full software inventory quickly became the priority, and ThreatLocker’ s onboarding model was built for pace. Each customer is paired with a dedicated solutions engineer who works as an extension of their IT team.“ We were working with Sam Sundell, who was doing pre-audits and helping identify gaps in the environment,” Peter continues.“ He became an extension of TLG Peterbilt’ s IT team,” Peter explains.” TLG Peterbilt also adopted a package that bundled privileged access management, DLP-style storage control and USB blocking.
