ThreatLocker

Security today is not failing because of a lack of tools. It is failing because operating systems were never designed to assume breach. Traditional security stacks still rely on detection, signatures and response yet modern attacks move faster than any response window.

Fortuna Data partners with ThreatLocker to deliver zero-trust operating environments that fundamentally change how endpoints, servers and applications behave — transforming every device into a locked-down, policy-controlled execution environment that allows only what is explicitly approved to run.

Instead of attempting to detect malicious behaviour after execution, ThreatLocker enforces control before execution. Nothing runs, nothing installs and nothing changes without explicit policy authorisation. This removes entire classes of attack — ransomware, supply-chain compromise, lateral movement, privilege escalation and zero-day malware by design, not by detection.

ThreatLocker operates as a full control plane across the operating system, application layer, storage and user privilege stack. It replaces reactive security models with deterministic policy control, enabling organisations to define exactly what software, scripts, drivers, installers, updates and users are allowed to execute — and to enforce those rules continuously, automatically and centrally.

• Application allow-listing that blocks all unapproved executables, scripts and installers
• Ringfencing to isolate applications and prevent lateral movement
• Privilege control to remove persistent admin rights and eliminate misuse
• Storage control to prevent unauthorised data access and exfiltration
• Change control to approve updates, patches and configuration changes
• Centralised policy enforcement across servers, desktops and remote devices

Fortuna Data designs and deploys ThreatLocker as part of a complete zero-trust operating architecture. We build policy frameworks, privilege models, ringfencing boundaries and change-control pipelines that integrate into your broader infrastructure, identity and compliance ecosystems — creating environments that are not merely protected, but structurally resistant to compromise.

For organisations operating in regulated, data-intensive and mission-critical environments, this architecture delivers material business outcomes:

• Elimination of ransomware and zero-day execution risk
• Dramatic reduction in incident response workload
• Improved compliance and audit readiness
• Protection against insider misuse and credential compromise
• Stable, predictable and governable operating environments

Modern threats do not exploit vulnerabilities. They exploit permission.

Fortuna Data and ThreatLocker remove permission by default — and replace it with deterministic control.
