Summary

This role is critical for ensuring endpoint application control remains secure and usable for engineering teams, particularly by acting as a dedicated support function during the stabilization phase of a "Default-Deny" rollout.

In this role, you will be responsible for designing, implementing, auditing, and maintaining ThreatLocker policies across our organization (and/or client environments). You will play a critical role in preventing ransomware, malware, and unauthorized software execution by managing Application Whitelisting (Allowlisting), Ringfencing, Storage Control, and Elevation Control.

The ideal candidate has a strong background in system administration or cybersecurity, possess a deep understanding of Windows operating systems, and is passionate about achieving a true Zero Trust security posture.

Key Responsibilities

ThreatLocker Administration & Management

• Policy Creation & Tuning: Design, implement, and maintain ThreatLocker Application Allowlisting policies to ensure only authorized software can execute.
• Ringfencing: Configure and manage Ringfencing policies to restrict what authorized applications can do (e.g., stopping PowerShell from talking to the internet or blocking Word from launching cmd.exe).
• Elevation Control: Implement and manage least-privilege access, creating rules for users to run specific applications as administrators without granting full local admin rights.
• Storage Control: Define and enforce policies for securing USB drives, network shares, and local files against unauthorized access or data exfiltration.
• Manage allowlisting, Learning Mode, and temporary exceptions.

Monitoring, Auditing & Incident Response

• Approval Queue Management: Monitor and process daily ThreatLocker approval requests from users efficiently, balancing security with operational productivity.
• Learning Mode Audits: Review, analyze, and baseline new endpoints during the "Learning Mode" phase to ensure seamless transitions to "Secured Mode."
• Log Analysis & Reporting: Investigate blocked files, denied executions, and policy violations. Use ThreatLocker audit logs to identify potential security incidents or shadow IT.
• Integration: Collaborate with the SOC/SIEM team to forward ThreatLocker logs and integrate them into the broader security monitoring ecosystem.
• Triage blocked applications, scripts, DLLs, and installers.
• Track service metrics to ensure business productivity.

Maintenance & Strategy

• Environment Maintenance: Keep ThreatLocker agents updated across all endpoints and servers.
• Testing & Validation: Test software updates and patch deployments in a sandbox environment to ensure they comply with existing ThreatLocker rules before company-wide rollout.
• Documentation: Maintain clear, up-to-date documentation of standard operating procedures (SOPs), policy exceptions, and approval workflows.
• Maintain Ringfencing and policy standards.

Required Experience

• ThreatLocker Expertise: Minimum of 3 years of hands-on experience specifically managing, configuring, and troubleshooting ThreatLocker in a production environment.
• IT/Cybersecurity Background: 3+ years of experience in System Administration, Helpdesk Tier 3, Network Engineering, or a Cybersecurity operations role.
• OS Proficiency: Deep, foundational knowledge of Windows OS (Registry, File Systems, Services, Active Directory, and Group Policy).
• Experience with macOS or Linux is a strong plus.
• Scripting: Basic familiarity with PowerShell or Command Prompt for troubleshooting and automation.

Knowledge/Skills/Competencies

Soft Skills

• Analytical Thinking: Ability to dissect complex application dependencies (e.g., figuring out why a niche accounting software was blocked by a specific DLL file).
• Customer-Centric Communication: Ability to explain security restrictions to non-technical staff diplomatically and find ways to enable business operations safely.
• Attention to Detail: Zero Trust requires precision; a misplaced rule can either cause a security gap or halt business operations.

Preferred Certifications (A Plus, Not Required)

• ThreatLocker Professional or ThreatLocker Expert certifications.
• CompTIA Security+, CySA+, or Network+.
• Microsoft Certified: Windows Server or Azure Administrator.

Physical Demands

• Duties of this position are performed in a normal office environment.
• Duties may require extended periods of sitting and sustained visual concentration on a computer monitor or on numbers and other detailed data. Repetitive manual movements (e.g., data entry, using a computer mouse, using a calculator, etc.) are frequently required.
