In Industry 4.0, IT and OT are converging fast. That convergence delivers productivity, but it also creates a direct path for cyber threats to reach production systems. When OT risk is not managed, the impact is no longer limited to data. It becomes downtime, safety exposure, quality deviation, delayed deliveries, and loss of know how.
DigiSôter helps industrial leaders regain control of OT cyber risk through ISA/IEC 62443-based assessments designed for manufacturing realities. We focus on what decision makers need: clarity, priorities, and an execution path.
What DigiSôter delivers
1) Executive-ready view of OT cyber risk (not a technical report)
A leadership summary that highlights:
Top OT cyber risks and likely business impacts
Exposure hotspots (remote access paths, IT-OT links, critical zones)
Recommended decisions for CEO, CIO, CISO, Operations, and Plant Management
2) A detailed, prioritised remediation roadmap
A prioritised roadmap that separates:
Quick wins (fast risk reduction with minimal disruption)
Structural improvements (segmentation, resilience, governance)
It includes target posture guidance using ISA/IEC 62443 Security Levels, aligned to the criticality of each zone and conduit.
3) Optional transformation management
If requested, DigiSôter can manage the transformation program end to end:
Governance, planning, and coordination across IT, OT, engineering, and suppliers
Tracking of remediation actions, evidence, and measurable progress
Operationally realistic implementation, aligned to maintenance windows and production constraints
The human factor, addressed for the shop floor
In most industrial incidents, attackers exploit technology, but they succeed through day-to-day behaviors. DigiSôter complements the technical roadmap with practical, shop-floor cyber hygiene, focused on blue-collar realities.
We provide role-based best practices and training designed for operators, technicians, and maintenance teams, including:
Preventing sharing of PIN codes, passwords, and badges
Safer use of HMIs and engineering workstations (session locking, access discipline)
USB and removable media rules (what is allowed, what is prohibited, how to handle exceptions)
Recognizing and reporting suspicious situations (unexpected remote support, unknown laptops, rogue modems)
Secure vendor access habits (who authorizes, who supervises, what must be logged)
Training is concise, operational, and aligned with production constraints, using concrete examples from manufacturing environments, not generic IT awareness content.
What we typically assess (high-level, business-relevant)
Remote access: vendor connectivity, VPN/jump hosts, unmanaged modems, session control
Segmentation: IT-OT boundaries, zones and conduits, firewall rules, DMZ design
Backups and recovery: PLC/HMI/SCADA configuration backups, restore testing, immutability
Patching and vulnerabilities: risk-based patching, legacy constraints, compensating controls
Access management: privileges, shared accounts, contractor lifecycle, MFA feasibility
Monitoring and response: visibility, logging, escalation, OT-ready incident playbooks
Why DigiSôter
We bring cybersecurity rigor, and deep manufacturing experience. That means recommendations that reduce risk without compromising uptime, safety, or operational efficiency, and training that actually works on the shop floor.
If your production environment is connected, it is exposed. DigiSôter helps you move from exposure to controlled, resilient operations with a roadmap that can be executed.
