Pipeline operations, compressor stations, and SCADA networks are increasingly in the crosshairs of nation-state actors and ransomware gangs. xS IT delivers battle-tested operational technology (OT) cybersecurity designed for Houston midstream operators ā meeting TSA Pipeline Security Directives without disrupting a single BTU of throughput.
26 years of veteran-led IT expertise, applied specifically to the challenges, compliance requirements, and operational realities of midstream pipeline and energy operations in the Greater Houston area.
Purdue Model-based network zoning, DMZ architecture, and industrial firewall deployment (Claroty, Dragos, Nozomi) that isolates control networks from business IT ā preventing lateral movement between environments.
Continuous passive monitoring of your OT environment to discover every PLC, RTU, HMI, and historian on the network ā with real-time vulnerability intelligence and anomaly detection that never interrupts operations.
Full gap assessment and implementation support for TSA Security Directives SD-02D and SD-01C, including cybersecurity implementation plan (CIP) development, annual testing, and TSA-required reporting.
Role-based access controls, multi-factor authentication for remote access, and privileged session recording for all SCADA and DCS access ā meeting both TSA and NERC CIP remote access requirements.
A dedicated OT incident response playbook with tabletop exercises, tested isolation procedures, and defined manual override protocols ā so your team knows exactly what to do when (not if) an attack occurs.
Secure vendor access portals with just-in-time provisioning, session recording, and automatic time-limited access tickets ā eliminating the VPN credential sprawl that enabled the Colonial Pipeline attack.
From discovery through ongoing management, our process is designed to deliver measurable results at every phase ā with zero disruption to your operations.
Passive network monitoring identifies every device on your OT network ā including forgotten legacy assets ā without sending a single active probe that could disrupt operations.
We map your current architecture against TSA Security Directives, NIST SP 800-82, and IEC 62443, then deliver a prioritized risk register with remediation cost estimates and operational impact ratings.
Network segmentation, firewall rules, patch management programs for OT assets, and remote access security are deployed in controlled change windows designed around your operational schedule.
24/7 OT-aware SOC monitoring using Claroty or Dragos, with xS engineers who understand the difference between a cyber attack and a legitimate process anomaly ā reducing false positives that cause operational disruption.
"When TSA issued its pipeline cybersecurity directives, we needed an OT security partner who understood both the regulatory requirements and the operational realities of running a live pipeline. xS IT delivered both ā on time and without a single process interruption."ā Houston Midstream Operations VP | xSā¢ IT Consulting ā Veteran Family Founded and Operated
