Shieldworkz OT Vulnerability Assessment and Penetration Testing (VAPT) Service is a service offering for operational technology (OT) environments that identifies, prioritizes, and helps mitigate security weaknesses. The service is structured into several phases: - Pre-Assessment and Scoping: agentic AI based asset discovery, security maturity evaluation, risk exposure quantification, CVE pooling, and high risk command scanning to define the assessment scope and schedule. - Passive Vulnerability Assessment: non-intrusive evaluation to discover outdated firmware, weak access controls, network/asset misconfigurations, unsecured legacy systems, and insecure communication channels without impacting operations. - Penetration Testing: controlled simulation of real-world attack scenarios to test for unauthorized access, privilege escalation, and potential attack paths, conducted to avoid disruption to OT operations. - Cyber Risk Analysis and Reporting: prioritization of vulnerabilities based on risk and business impact with a risk score, remediation recommendations, and reporting of exploitable attack paths. - Mitigation: assistance implementing security controls and patch management strategies, breaking identified attack paths, continuous monitoring recommendations, and defense-in-depth approaches such as DMZ and microsegmentation. The service targets industrial control systems and OT networks to assess and improve security maturity across critical assets, communication protocols, and network architecture.</description> <parameter name="summary">OT/ICS vulnerability assessment and penetration testing service by Shieldworkz

Vestoria is a cloud platform from Soterics for tracking OT (operational technology) security maturity across multiple industrial sites. It replaces manual, consultant-driven assessments and static reports with a continuously updated view of maturity, risk, and investment priority per site and across an organization. The platform ingests site data, frameworks, processes, assets, and people information, and produces maturity scores, a cross-site comparison, a risk register, compliance evidence, and a management dashboard. Site teams complete plain-language assessments against frameworks such as IEC 62443 and NIST CSF (or custom controls) without requiring a security consultant. Identified risks are mapped to mitigations, owners, and acceptance criteria, and mitigations roll up into costed work packs across People, Process, and Technology (PPT) that form an investment roadmap. Vestoria also functions as a single pane of glass for aggregating alerts and managing security appliances that protect OT environments, such as remote access, network monitoring, EDR, firewalls, and bastions, across on-prem, cloud, and hybrid deployments. It continuously monitors compliance against frameworks like IEC 62443, NIS2, and NIST CSF, alerting users to compliance drift and providing associated remediation/mitigation plans. Vestoria is designed for multi-site manufacturers, critical infrastructure operators, small and mid-sized industrial organizations, and MSSPs/OT consultancies delivering OT security services. It is offered as a hosted cloud platform with no on-premises installation, connecting to existing tools via secure connectors. It can also work alongside Soterics' Vigilant product, which handles incident correlation and response.</description> <parameter name="summary">Cloud platform tracking OT security maturity, risk, and investment across multiple industrial sites
