OT/IT Security & Industrial Cyber Resilience
Protecting production systems where IT meets OT – securing SCADA, ICS and industrial networks without disrupting operations.
Your production is only as secure as its weakest network segment
When IT and OT converge without adequate security, a single compromised endpoint can shut down an entire production line.
- Do your production systems still operate on flat networks where a breach in office IT can reach shop floor PLCs?
- Is your SCADA infrastructure protected against targeted attacks, or are you relying on air gaps that no longer exist?
- Can you maintain production continuity if a ransomware attack hits your MES or industrial control systems?
The convergence of IT and OT creates enormous efficiency gains but also opens new attack vectors that traditional IT security approaches cannot address. Industrial control systems have different lifecycles, different availability requirements and different risk profiles than enterprise IT. Securing them requires specialized expertise that bridges both worlds.
At T.A.S. FORCE, we bring years of hands-on experience securing OT environments at global industrial scale – from production plants to critical infrastructure operators. We understand that in production, availability is not negotiable and security measures must work with operational reality, not against it.
OT Security Assessment & Architecture Review
- Comprehensive assessment of OT network architecture based on the Purdue Reference Model
- Identification of IT/OT convergence risks and unsecured interfaces
- Asset inventory and vulnerability assessment of industrial control systems
- Gap analysis against IEC 62443 security levels and zone/conduit model
- Risk-prioritized remediation roadmap with quick-win and strategic measures
We make the invisible visible – most companies don’t know what’s actually connected in their OT environment until we map it.
Network Segmentation & Defense-in-Depth
- Design and implementation of zone-based network architecture per IEC 62443-3-2
- Industrial DMZ design separating IT, OT and safety networks
- Secure remote access solutions for maintenance and vendor support
- Implementation of monitoring and anomaly detection for industrial protocols
Proper segmentation is the single most effective measure to limit the blast radius of an OT cyber incident.
Industrial Security Program Development
- Development of OT-specific security policies and procedures
- Patch management strategies for industrial systems (balancing security with availability)
- OT-aware backup and recovery planning
- Security awareness training for production staff and maintenance teams
- Establishment of OT Security Operations capabilities
Security programs that work in the factory, not just in the server room.
OT Cyber Resilience & Business Continuity
- OT-specific incident response planning and tabletop exercises
- Production continuity planning for cyber scenarios
- Recovery strategy design (safe state, isolation, controlled restart)
- Integration of cyber resilience with existing safety and operational continuity programs
The question is not if an OT incident will happen – but whether your production can recover in hours instead of weeks.

"Why T.A.S. FORCE?" Your questions, our answers
Why T.A.S. FORCE for OT/IT Security?
- Real OT experience – We’ve secured production environments at global scale (200+ sites across 40+ countries).
- Production-aware – We understand that availability trumps confidentiality in OT. We design security that works with production constraints.
- Standards-based – IEC 62443, Purdue Model, NIST CSF 2.0 – not proprietary frameworks.
- Cross-domain – We bridge the communication gap between IT security teams and production/maintenance staff.
