SecurityGate Guided Assessment Services is a professional services offering from SecurityGate.io that provides expert-led cybersecurity risk and control assessments, primarily targeting Operational Technology (OT) and Industrial Control System (ICS) environments. The service is delivered by a team of assessment experts based in Houston and Milan, supplemented by an approved global network of ICS partners. Assessments can be conducted remotely or onsite. Three service tiers are offered: **Guided Assessment:** A third-party expert is present throughout the assessment process to provide instruction and validation, while the client's own team leads the exercise. This model is designed to build internal team capabilities. **SecurityGate-Led Assessment:** An external expert team takes the lead on conducting the assessment. This is applicable when mandated by governance or regulatory bodies, when the client team lacks experience, or when internal resources are otherwise occupied. The team delivers data models to drive improvement programs and validate key controls. **Annual Audit:** Designed for organizations with more mature cybersecurity programs. Experts gather evidence, conduct stakeholder interviews, and evaluate documented policies and procedures to assess the effectiveness of existing cyber and risk programs in adapting to changing inputs. The service is aimed at asset owners who need to report cybersecurity program status to leadership or regulatory bodies but lack sufficient internal resources to conduct assessments independently. SecurityGate.io has been included in Gartner's Market Buyer's Guide for Operational Technology and the Hype Cycle for Cyber and IT Risk Management (2021 and 2022).
