OT Security
Safeguarding industrial control systems and critical infrastructure against evolving cyber threats.
Specialized OT/ICS security assessments aligned to IEC 62443 and NIST SP 800-82 — protecting SCADA, PLCs, and industrial networks from cyber threats without disrupting operations.

Our Service Offerings
OT/ICS Security Assessment
Comprehensive assessment of your industrial control systems environment — identifying vulnerabilities in SCADA, DCS, PLC, and HMI systems without disrupting operations.
Network Architecture Review
Evaluate OT network segmentation, IT–OT convergence zones, and remote access pathways for security gaps and compliance against IEC 62443 zone/conduit models.
Asset Inventory & Risk Profiling
Passive discovery and cataloguing of all OT assets — including legacy devices — with risk scoring based on exploitability, criticality, and connectivity.
Vulnerability & Patch Analysis
Identify known CVEs affecting OT devices, assess compensating controls for unpatched systems, and develop a safe patching strategy that does not impact uptime.
IT–OT Convergence Security
Assess risks arising from the convergence of IT and OT networks — including cloud connectivity, vendor remote access, and enterprise-to-plant integration.
Incident Response for OT
Develop and test OT-specific incident response plans and playbooks to ensure rapid, safe response to cyber incidents in industrial environments.

What You Receive
How It Works
A structured, repeatable process that ensures consistent, high-quality outcomes for every engagement.
OT Environment Discovery
Passive, non-intrusive discovery of all OT assets, network topology, and communication flows.
Architecture Review
Evaluate network segmentation, zone definitions, and IT–OT integration points against IEC 62443 best practices.
Vulnerability Analysis
Identify known vulnerabilities in OT devices, software, and protocols — without active scanning that could disrupt operations.
Risk Assessment
Score and prioritize risks based on asset criticality, exploitability, and potential safety and operational impact.
Remediation Roadmap
Develop a practical, phased remediation plan that prioritizes safety and operational continuity.
Compliance Alignment
Map findings to IEC 62443, NIST SP 800-82, and relevant sector-specific regulatory requirements.
The SecurEpitome Difference
Operational Technology (OT) Security focuses on safeguarding industrial control systems through a comprehensive gap assessment of the existing OT environment. We evaluate current architectures, assets, network segmentation, access controls, and operational processes against standards such as IEC 62443 and NIST SP 800-82. The assessment identifies security gaps, legacy risks, and IT–OT convergence exposures, delivering a prioritized remediation roadmap to enhance safety, resilience, compliance, and uninterrupted industrial operations.
