[Soterics Consultancy Services](https://cybersectools.com/tools/soterics-consultancy-services) Soterics Consultancy Services is a professional services offering focused on operational technology (OT) security. The service delivers OT security assessments, gap analysis, architecture reviews, risk analysis, and compliance consulting for industrial environments. The offering evaluates an organization's OT security posture to identify vulnerabilities, risks, and compliance gaps, then produces a prioritized, budgeted roadmap tied to operational and business constraints. Consultants map findings to frameworks including IEC 62443, NIS2, NIST CSF, and ISO 27001/27002, and translate technical findings into business-impact terms for leadership decision making. Assessments are designed to run without requiring operational downtime and typically take 2-6 weeks depending on scope, with shorter focused assessments available for specific areas such as network segmentation or remote access. Engagements produce a report with findings, risk ratings, an executive summary, and a technical appendix, and can feed directly into Soterics implementation and managed services offerings for organizations that want support executing the roadmap. The service is positioned as OT-native, staffed by consultants with backgrounds in industrial environments, differentiating it from generic IT security audits that may not account for industrial protocols, safety requirements, and availability constraints in OT settings.
