OT Cybersecurity for Water Infrastructure

Disciplined, standards-aligned, federally compliant. Not a marketing veneer over IT tools - engineering done by people who understand the plant floor.

The OT Threat Landscape

Water utilities now sit inside the same threat envelope as the electric sector, but most are still operating with flat networks, shared credentials, and unsupported control systems. The federal guidance has converged - IEC 62443, NIST SP 800-82 Rev 3, NIST CSF 2.0, EPA Cyberwater, and WaterISAC’s 15 Cybersecurity Fundamentals all point in the same direction. We turn that guidance into executed, documented, defensible engineering work.

OT Cybersecurity Catalog

Assess

  • Risk & resilience assessments (AWIA Section 2013, AWWA G430 / G440)
  • OT asset inventory & passive network discovery
  • IEC 62443-3-2 detailed risk assessments
  • NIST CSF 2.0 security maturity scoring
  • OT segment penetration testing (with cleared partners)

Remediate

  • Network segmentation & firewall zone design
  • Industrial DMZ (IDMZ) architecture
  • Secure Remote Access (SRA) deployments
  • OT patch & vulnerability management
  • Backup & disaster recovery hardening
  • Emergency Response Plan (ERP) authoring

Operate

  • 24/7 OT monitoring via SOCs (Dragos, Claroty, Nozomi)
  • Incident response retainer support
  • OT security tabletop exercises
  • Quarterly security posture & compliance reviews
  • Vulnerability disclosure management

Compliance & Security Frameworks

AWIA Section 2013

Every community water system serving 3,300+ people must certify. Round 2 submissions are due 2025–2026. We author the assessment, the ERP, and the certification package.

IEC 62443

Internationally recognized OT cybersecurity standard. We design and certify zone-and-conduit architectures, security level targets, and evidence packages.

NIST SP 800-82 Rev 3

The federal Industrial Control Systems (ICS) security baseline. We map every control requirement directly to plant reality.

EPA / WaterISAC

Sector-specific cybersecurity guidance and WaterISAC's 15 Fundamentals translated into practical plant-floor engineering scope.
