IT for Petrochemical & Refining
The Houston Ship Channel is the largest petrochemical complex in the United States and one of the most consequential cybersecurity environments in the world. Refineries, chemical plants, terminals, and midstream operators must protect process control systems from ransomware and nation-state threats while satisfying TSA directives, ISA/IEC 62443, CFATS, and cyber insurance underwriting. LayerLogix delivers managed IT and OT cybersecurity services built for the unique demands of Gulf Coast petrochemical and refining operations.
What We Offer
Comprehensive solutions tailored for Houston-area businesses
OT / IT Network Segmentation
The Purdue reference model and ISA/IEC 62443 require strict segmentation between corporate IT and plant OT networks. We design and implement segmented zones, conduits, and DMZs that protect the process network from commodity ransomware without breaking the data flows your operations and business teams depend on.
SCADA & ICS Cybersecurity
Honeywell, Emerson, Yokogawa, Rockwell, and Siemens control systems need cybersecurity protection that respects their availability and determinism requirements. We deploy passive OT monitoring, network visibility, and protective controls that strengthen your ICS security without interfering with the process.
ISA/IEC 62443 Compliance
The recognized global standard for industrial automation cybersecurity. We perform zone and conduit analysis, security level assessment, and gap remediation against 62443-2-1 and 62443-3-3. Essential for refinery operators, EPCs, and systems integrators working across the Gulf Coast.
TSA Pipeline Cybersecurity Directive Support
Pipeline operators must meet TSA Security Directives Pipeline-2021-01B and subsequent directives covering incident reporting, vulnerability assessments, cybersecurity implementation plans, and architectural controls. We help midstream and refinery operators achieve and document compliance.
Process Safety & High-Availability IT
Plant systems that support process safety — alarms, historians, safety instrumented systems, and engineering workstations — must be highly available and carefully managed. We provide patching strategies, change control, and redundant infrastructure that respect OT's availability-first requirements.
Secure Remote Access for Vendors & Engineers
Controlled, auditable remote access for DCS vendors, instrumentation engineers, and SIS specialists — replacing legacy modems and unmanaged jump boxes with modern privileged access management that logs every session and enforces least privilege.
Why Choose LayerLogix?
Serving businesses throughout the Greater Houston area including Houston, The Woodlands, Spring, Katy, Sugar Land, Conroe, Pearland, Dallas, Austin.
Protect Against Ransomware Crossing Into OT
The Colonial Pipeline incident showed how IT-side ransomware can force OT shutdowns. Our segmentation, monitoring, and incident response protect the process network from IT-side compromise — preserving your operational continuity and protecting revenue.
Satisfy Regulators, Insurers, and Customers
TSA directives, CFATS, insurance cyber underwriting, and major-owner audits all demand documented industrial cybersecurity programs. We help you build and maintain the evidence package that satisfies every stakeholder.
Minimize Unplanned Downtime
For a refinery or ethylene cracker, unplanned downtime can mean millions of dollars per day. Our change control, patch management, and OT-aware monitoring reduce the IT and cybersecurity causes of unplanned shutdowns.
Bridge the IT / OT Organizational Gap
IT and operations often speak different languages and operate on different priorities. We bring both perspectives — enterprise IT discipline combined with respect for the process — and help build the collaboration your security program needs.
Purpose-Built for the Gulf Coast
We operate in the Houston Ship Channel corridor and understand the local ecosystem — the contractor workforce, the permitting environment, the hurricane preparedness demands, and the specific systems deployed across Baytown, Pasadena, Deer Park, Texas City, and Beaumont-Port Arthur.
