Zero Trust — deny by default, permit by exception.
Stop chasing yesterday’s malware. With ThreatLocker allowlisting, Ringfencing™ and Zero Trust principles, only software you have approved can run — full stop.
Never trust. Always verify.
Zero Trust replaces "inside vs outside the firewall" with continuous verification of every user, device and app.
Application allowlisting
Only approved applications and scripts can execute. Ransomware can’t run if it can’t run.
Ringfencing™
Even legitimate apps (Word, PowerShell, Acrobat) are restricted in what they can talk to.
Storage control
Granular control over removable media, USBs, cloud-sync clients and external drives.
Identity-first
Continuous Conditional Access, phishing-resistant MFA, device compliance and just-in-time admin.
Microsegmentation
Limit east-west traffic. A compromised endpoint can’t pivot across the network.
Continuous verification
Every request re-evaluated — never trust a session because it was authenticated an hour ago.
A ThreatLocker rollout that doesn’t break the business.
Allowlisting can be painful — done wrong. We use ThreatLocker’s learning mode plus a structured 60-day rollout so the day you go to "deny by default" is a non-event for your users.
- ✓Learning modeTwo weeks of monitoring — we build the allowlist from what your business actually uses.
- ✓Pilot groupRoll out to IT and admins first. Iron out exceptions before reaching end-users.
- ✓Phased enforcementWave-by-wave to user groups, with a 60-second self-service approval workflow.
- ✓24/7 approval deskWhen a user requests new software, our SOC reviews and decides — fast.
- ✓Audit-ready evidenceEvery approval and denial logged for ISO 27001 / Cyber Essentials Plus.
Frequently asked questions
Will users be locked out of stuff they need?
No. The 60-day onboarding builds an allowlist from real usage. New requests are reviewed in minutes — not days.
Is ThreatLocker only for Windows?
It’s strongest on Windows, with growing macOS support. We complement it with Defender/SentinelOne on other platforms.
How is this different from antivirus or EDR?
AV/EDR detect bad. ThreatLocker only allows known good — a fundamentally stronger model that defeats zero-days.
Do we still need EDR if we have ThreatLocker?
Yes — defence in depth. EDR catches behaviour ThreatLocker doesn’t, and gives you the forensic record.
