SightGain Threat Exposure Management Platform is a cybersecurity assessment automation tool that connects to existing security infrastructure to provide continuous threat exposure monitoring and validation. The platform automates security assessments and analyzes data in real-time to evaluate the performance of security technologies, processes, and personnel. The platform operationalizes MITRE ATT&CK framework to conduct live-fire testing in production environments, providing visibility into security operations effectiveness against real-world threats. It quantifies business risk exposure through automated testing rather than estimates or compliance checklists. The system includes an embedded cyber range that trains security teams against emulated threats using existing tools in live environments. It evaluates how people, processes, and technologies work together under pressure to reduce risk. The platform generates analytics that calculate return on investment for cybersecurity investments and provides data to support resource allocation decisions. It identifies gaps in security portfolios and evaluates alternative security investments based on performance data. Automated compliance monitoring capabilities replace manual control checks, enabling continuous compliance certification processes. The platform produces reports that communicate security program performance to business leaders, boards, and external compliance stakeholders.
