Why Streamline for OT Cybersecurity
With 15+ years securing industrial control systems, Streamline brings deep OT expertise that IT-focused security firms can’t match. We understand the operational constraints that make OT security fundamentally different: systems where downtime means safety incidents or millions lost.
Our standards-based methodology covers IEC 62443, NERC CIP, NIST CSF, and TSA/PHMSA directives across pipeline SCADA, electric utilities, oil and gas, and water treatment. Every engagement delivers complete, audit-ready documentation: network diagrams, risk assessments, firewall configurations, incident response plans, and compliance evidence packages.
The OT Cybersecurity Challenge
Modern connectivity is essential. Legacy OT wasn’t built for it. You need security that protects infrastructure without breaking operations.
Security Risks You Face
- Increased attack surface from cloud and remote access
- Legacy systems with unpatched vulnerabilities
- Regulatory pressure: NERC CIP, TSA Pipeline Security, CISA directives
- Ransomware targeting OT systems
- Insider threats from contractors with excessive access
- Limited OT security expertise on IT teams
- IT and OT network convergence breaking air gaps
- Supply chain attacks through vendor access
Streamline's Security Approach
- Defense-in-depth with multiple security layers
- Standards-based design using IEC 62443 and NIST
- Purdue Model network segmentation isolating OT from IT
- Zero trust principles verifying every access request
- Secure remote access without VPNs exposing OT networks
- Continuous monitoring with ICS-specific threat detection
- Compliance documentation meeting NERC CIP and TSA requirements
- Incident response plans tested through tabletop exercises
