OT/IT security that protects operations, not just networks.
Cloud security and infrastructure for discrete and process manufacturers. OT/IT network security, industrial SIEM, and cloud architecture that extends visibility from corporate networks to the plant floor without creating operational risk.
Manufacturing security sits at the intersection of corporate IT and operational technology: two environments with fundamentally different priorities, patch cycles, and availability requirements. The cloud journey for manufacturers is also unique. Corporate systems migrate to cloud. Plant floor systems stay on-premise or at the edge. And somewhere in between, attackers look for the path from one to the other.
Yearling Solutions brings practitioners who understand both environments. We design security architectures that provide IT-level visibility into OT environments without disrupting production, implement SIEM platforms that can ingest industrial data sources, and help manufacturers think through the security implications of every OT/IT integration before it is built.
Standards & Industry Context
The standards and frameworks that shape cloud and OT security programs in manufacturing.
NIST SP 800-82 (OT Security)
Guide to OT security for industrial control systems including SCADA, DCS, and PLCs. The foundation for ICS security program design.
IEC 62443
Industrial automation and control system security standards covering security zones, conduits, and security levels for OT environments.
CMMC 2.0 (Defense Manufacturing)
CUI data handling and cloud security controls for defense manufacturers and contractors in the DoD supply chain.
NIST CSF
Cybersecurity framework adoption for manufacturing organizations bridging IT and OT security programs.
CISA Cross-Sector CPGs
CISA's Cross-Sector Cybersecurity Performance Goals applicable to manufacturing critical infrastructure.
ISO 27001 / IEC 27019
Information security management standards with energy and utility sector extensions applicable to process manufacturing environments.
What We're Seeing
The security realities driving conversations with manufacturing infrastructure leaders today.
Ransomware that pivots from IT to OT
The most damaging manufacturing cyberattacks begin on corporate networks and reach plant floor systems through inadequate IT/OT segmentation. Recovery is measured in days of lost production, not hours of IT downtime.
No visibility into industrial control system activity
Most SIEM deployments stop at the corporate network boundary. PLCs, HMIs, and historians generate events that no security team is watching. OT-aware detection is no longer optional for manufacturers in critical infrastructure sectors.
Remote access to OT environments without security controls
Equipment vendors and automation contractors require remote access to plant floor systems. Access granted through VPN or directly to OT networks without multi-factor authentication and session monitoring creates significant exposure.
Cloud adoption without OT security review
Manufacturers adopting cloud platforms for ERP, supply chain, and analytics often connect these systems to plant floor data sources without a security review. Each integration creates a potential path from cloud to OT.
