Why Security Architects Choose Streamline

The expertise and experience that sets us apart

Deep OT Security Expertise

14+ years securing industrial control systems. IEC 62443 certified. NERC CIP compliance experience. SCADA protocols (DNP3, Modbus, OPC), DCS platforms, safety systems. Security requirements and operational constraints.

Standards-Based Methodology

Proven frameworks. IEC 62443, NIST Cybersecurity Framework, ISA/IEC zones, Purdue Model, CIS Controls, MITRE ATT&CK for ICS. Reduce risk, demonstrate due diligence to regulators.

Proven in Critical Infrastructure

Production systems protecting critical operations. Pipeline SCADA under PHMSA/TSA. Electric utilities meeting NERC CIP. Oil and gas, water treatment, pharmaceutical manufacturing. Systems that can’t go down or be breached.

Complete Security Deliverables

Ready for implementation and audit. Network diagrams (Purdue zones). Firewall rules, DMZ configs. Risk assessments. Security policies. Incident response plans. Compliance evidence packages. Documentation for technical teams and auditors.

The OT/IT Convergence Security Challenge

Modern operations need cloud connectivity and remote access—but IT security doesn’t work in OT. Industrial systems need security that protects infrastructure while maintaining real-time operations.

Security Risks You Face

  • Increased attack surface: Cloud and remote access create threat entry points.
  • Legacy systems: Older SCADA wasn't designed for modern threats.
  • Regulatory pressure: NERC CIP, TSA, CISA compliance required.
  • Limited expertise: Most teams lack OT knowledge.

Streamline's Security Approach

  • Defense-in-depth: Multiple security layers.
  • Standards-based: IEC 62443, NIST frameworks.
  • Network segmentation: Purdue zones isolate OT from IT.
  • Zero trust: Verify every access.
  • Compliance: Meet NERC CIP, TSA, PHMSA requirements.

What Security Architects Get

  • Comprehensive architecture: Network diagrams, firewall rules, DMZ design.
  • Risk assessments: Threat modeling, gap analysis.
  • Implementation roadmap: Phased plans.
  • Documentation: Policies, procedures, incident response.
  • Compliance: Evidence packages for NERC CIP, TSA.
  • Training: Knowledge transfer.

Comprehensive Security Architecture Services

End-to-end cybersecurity for industrial operations

Network Segmentation & Purdue Model

Isolate critical control systems. Implement Purdue zones (Levels 0-5). Industrial DMZ architectures. 

Strict firewall rules between zones. Unidirectional gateways. VLAN segmentation. Air-gap when required. Stop lateral movement, contain incidents.

IEC 62443 Cybersecurity Framework

Industry-recognized OT security standard. Gap assessment. Security Level determination for assets.

Zone and conduit architecture. Fundamental requirements (FR1-FR7): identification, access control, integrity, confidentiality, restricted flow, response, availability. Risk methodology, compliance documentation.

Secure Remote Access & Identity

Zero trust remote access. Multi-factor authentication mandatory. Jump servers, privileged access management.

VPN with certificate authentication. Role-based access control. Session recording, audit logging. Time-limited vendor access. Hardware security tokens. Secure, auditable access.

NERC CIP & Regulatory Compliance

Meet electric utility cybersecurity requirements. NERC CIP v5/v6 compliance. ESP and Protected Cyber Assets identification.

CIP-002 through CIP-014 implementation. TSA Pipeline Security Directives. PHMSA integrity management. Evidence collection. Internal assessments before audits. Security becomes compliance.

Defense-in-Depth Architecture

Multiple security layers. Network: Firewalls, IDS/IPS, segmentation. Endpoint: Antivirus, whitelisting, USB control.

Physical: Badge access, surveillance. Application: Secure coding, vulnerability scanning. Data: Encryption. Monitoring: SIEM, log aggregation, anomaly detection. Layered defense.

Incident Response & Security Operations

Prepare and respond to incidents. Incident response plan development. Cyber incident response team training.

Security monitoring and alerting. ICS-specific threat intelligence. Forensics for OT environments. Tabletop exercises. SOC integration. Business continuity planning. Detection, containment, eradication, recovery.
