SecurityGate is an OT/ICS-focused cybersecurity assessment and risk management platform designed for critical infrastructure environments. It provides cyber teams with tools to assess, document, and improve their security posture across operational technology environments. The platform includes over 20 pre-built industry frameworks (including NIST-CSF) and a library of more than 3,000 control questions. Users can select existing frameworks, upload custom questionnaires, or mix and match controls to suit their specific needs. SecurityGate supports both internal assessments and third-party vendor assessments. Team members and external vendors can be assigned tasks, with centralized management of feedback and remediation workflows. Evidence, artifacts, and observations can be attached directly to assessments. The platform provides visual dashboards and automated control mapping across threats, risks, control families, and impact levels. Reports are generated to support roadmap planning and communicate metrics to senior leadership, including views by site, function, and geography. Remediation management is handled within the platform, with an open API available to connect to external ticketing solutions. Security features include two-factor authentication via Google Authenticator, LastPass, and Microsoft Authenticator, as well as a bring-your-own-key (BYOK) option within AWS environments. The platform also offers native integrations with asset inventory tools and ticketing solutions.
