OT Security Services
96% of OT security incidents originate from IT-level compromises, yet most industrial organizations lack visibility into their operational technology networks. The OT security market will reach $50 billion by 2030 as ransomware attacks on critical infrastructure surge 40% annually. Opsio delivers end-to-end OT security services — from asset discovery and risk assessment through network segmentation, monitoring, and managed OT SOC — protecting the systems that run factories, power grids, and essential services.

What's Included
OT Asset Discovery & Inventory
Passive and active discovery of all OT assets — PLCs, HMIs, RTUs, SCADA servers, sensors, and network devices — including shadow assets not tracked by existing CMDB. Real-time asset inventory with firmware versions, communication paths, and risk scoring.
OT Network Segmentation
Design and implementation of zones and conduits architecture per IEC 62443. Micro-segmentation between safety, control, and enterprise networks using industrial-grade firewalls and DMZs. Purdue Model enforcement with monitored conduit policies.
OT Threat Monitoring & Detection
24/7 monitoring of OT network traffic using deep packet inspection for industrial protocols (Modbus, OPC UA, DNP3, EtherNet/IP, Profinet). Anomaly detection for unauthorized commands, firmware changes, and lateral movement. Integrated with our managed OT SOC.
ICS/SCADA Security Assessment
Comprehensive security assessment of ICS and SCADA environments covering network architecture, access controls, patch status, configuration hardening, and incident response readiness. Aligned to IEC 62443 security levels and NIST 800-82 controls.
OT Vulnerability Management
Risk-prioritized vulnerability management that respects operational uptime constraints. Virtual patching, compensating controls for unpatchable legacy systems, and coordinated maintenance window patching. Integration with vendor advisories from Dragos, Claroty, and ICS-CERT.
NIS2 & Compliance for OT
NIS2 Directive compliance for essential and important entities operating OT environments. Gap assessment, security control implementation, incident reporting procedures, and supply chain security requirements. Also covers NIST 800-82, IEC 62443, and sector-specific regulations.

Two enterprise security platforms. Included free.
Others pay a fortune for continuous vulnerability monitoring and a unified security-and-cost workspace — and then pay again for the people to run them. Every Opsio managed-cloud customer gets both, at no extra cost, with our engineers acting on what they surface.
SeqOps
Continuous vulnerability monitoring across your entire cloud & server estate — always on, never in the way.
- Every vulnerability, misconfiguration & exposure found continuously across AWS, Azure, GCP, Windows & Linux
- AI ranks findings by real risk, so effort goes where it matters
- Continuous compliance scoring: NIS2 · ISO 27001 · GDPR · PCI · HIPAA
- Read-only — collects security metadata, never your data
Opsio Shield
One intelligent workspace that unifies security posture, compliance scoring and cloud cost — so nothing hides between tools.
- Security posture, compliance score & multi-cloud spend on one live dashboard
- Cost anomalies & budget overruns caught before the invoice lands
- Auto-generated compliance evidence & vulnerability reports
- Encrypted secrets, mandatory MFA & row-level isolation by design
It's simply part of being an Opsio managed-cloud customer.
Secure Your Industrial Operations With OT Cybersecurity
Operational technology (OT) — the hardware and software that monitors and controls physical processes in factories, power plants, water treatment facilities, and transportation systems — was never designed for a connected world. Industrial control systems (ICS), SCADA platforms, and PLCs were built for reliability and safety over decades-long lifecycles, not for defending against nation-state actors, ransomware gangs, and AI-powered attacks that now target them daily. The convergence of IT and OT networks has created an expanded attack surface where a single compromised IT credential can cascade into physical process disruption. Dragos reports that 60% of organizations experienced OT security incidents in 2025, while the SANS Institute found that only 52% have adopted OT-specific monitoring. The gap between exposure and visibility is where industrial breaches happen — and where Opsio's OT security services close the risk.
Opsio takes a defence-in-depth approach to OT security, layered across the Purdue Model architecture: asset discovery and inventory at every level, network segmentation using zones and conduits per IEC 62443, continuous OT network monitoring with industrial-protocol-aware detection, vulnerability management that respects operational uptime, and a managed OT SOC staffed with analysts who understand both cybersecurity and industrial processes. We secure without disrupting production.

OT Security Services — FAQ
What is the difference between IT security and OT security?
IT security protects data confidentiality, integrity, and availability. OT security protects physical processes and human safety. OT environments have unique constraints: 20-30 year asset lifecycles, real-time availability requirements, legacy protocols without authentication, and safety systems that must never be disrupted. A security control appropriate for IT (automated patching, endpoint agents) can cause production shutdowns in OT. Our approach respects these constraints while closing security gaps.
Can you secure OT without disrupting production?
Yes. Our approach uses passive network monitoring (no inline devices that could fail-open), staged segmentation deployed during planned maintenance windows, and virtual patching for systems that cannot be updated. We have never caused an unplanned production stoppage during an OT security deployment. Asset discovery uses passive traffic analysis supplemented by controlled active scans only during approved windows.
How does OT security relate to NIS2 compliance?
NIS2 classifies many OT-operating organizations as essential or important entities — including energy, transport, water, healthcare, and manufacturing. These entities must implement risk-based cybersecurity measures, report significant incidents within 24-72 hours, and ensure supply chain security. Our OT security services directly address NIS2 requirements: risk assessments, network segmentation, monitoring, incident response, and regular security testing.
What industrial protocols do you monitor?
We provide deep packet inspection for 40+ industrial protocols including Modbus TCP/RTU, OPC UA, OPC DA, DNP3, EtherNet/IP (CIP), Profinet, Profibus, BACnet, IEC 61850, IEC 104, HART, Foundation Fieldbus, and MQTT. Our detection engine understands the semantics of these protocols — it can distinguish between legitimate control commands and unauthorized process manipulation attempts.
