OT Endpoint Protection
Purpose-built security for industrial endpoints.
Secure HMIs, Engineering Workstations, and PLC Programming Devices
Operational Technology (OT) endpoints—like Human–Machine Interfaces (HMIs), engineering workstations, historians, and PLC programming laptops—are critical to plant operations. These systems often run legacy OS versions, use vendor-specific tools, and cannot be patched or scanned like typical IT endpoints. That makes them prime targets for ransomware, unauthorized logic changes, and remote-access abuse.
LA Technologies’ OT Endpoint Protection solutions safeguard these specialized endpoints without disrupting production, ensuring safety, availability, and integrity of your industrial processes.
Protecting Safety-Critical OT Endpoints
Legacy & constrained devices
Many OT endpoints run unsupported OS or proprietary applications that limit traditional security controls.
High-impact risks
A single compromised HMI or engineering workstation can halt lines, corrupt PLC logic, or trigger unsafe states.
Operational constraints
Security must respect change-control windows, vendor tooling, and process safety—no intrusive agents or aggressive scans.
Our Application Security Solutions
OT-Safe Endpoint Hardening
Baseline configurations for HMIs, historians, and engineering stations (services, accounts, policies, removable media controls) tailored to vendor guidance.
Application Control / Allow-Listing
Permit only trusted engineering tools and runtime binaries; block unauthorized executables and scripts to prevent logic tampering and malware execution.
Advanced Endpoint Protection (Agented or Agentless Options)
Deploy EDR/XDR where feasible on Windows/Linux endpoints; use agentless monitoring for constrained systems to observe changes and suspicious behaviors without impacting controllers.
Removable Media Governance
Control and scan USB usage on programming laptops; enforce cryptographic signing of ladder logic/firmware files and maintain transfer logs.
Privilege & Session Controls
Enforce least privilege on engineering accounts, MFA for admin access, and session recording on maintenance activities (links with OT Privileged Access Management).
Patch & Compensating Controls
Plan patching aligned to shutdown windows; for unpatchable assets, implement compensating controls (isolation, ACLs, app control, enhanced monitoring).
Change Control & Integrity Monitoring
Track and approve PLC/HMI project hanges; alert on unauthorized firmware updates,logic downloads, or configuration drifts.
Integration Across OT Security
Asset Discovery
Validate endpoint inventory, owners, and criticality.
Network Segmentation
Place endpoints in appropriate zones; restrict conduits to required protocols.
Threat Detection & IR
Stream endpoint events to OT monitoring; use OT‑specific runbooks for safe containment.
Vulnerability Management
Prioritize endpoint findings and plan remediation without impacting production.
Benefits
Reduce Ransomware & Logic Tampering Risk
Block unauthorized executables and monitor high‑risk activities on engineering devices.
Protect Safety & Uptime
OT‑safe controls that respect process constraints and vendor requirements.
Strengthen Governance
Complete audit trails of admin actions, USB transfers, and configuration changes.
Compliance Alignment
Controls mapped to industrial security practices (e.g., IEC 62443 principles) and internal EHS/quality policies.
Typical Use Cases
Hardening and allow‑listing on HMIs and historians in a production line
EDR deployment on Windows-based engineering workstations with vendor tool compatibility testing
USB control and scanning for firmware updates to PLCs and drives
Integrity monitoring for unauthorized logic downloads during off-hours
MFA and session recording for third‑party maintenance activities
How Engagement Works ?
Discovery & Feasibility Assessment
Identify endpoint types, OS/vendor constraints, and operational windows.
Control Design
Define allow‑lists, hardening baselines, privilege policies, and monitoring integrations.
Pilot & Compatibility Tests
Validate controls with vendor tools and plant operations; adjust for OT safety.
Rollout
Phased deployment aligned to change windows; documented procedures and training.
Operate & Improve
Continuous monitoring, periodic reviews, and updates to baselines and allow‑lists.
