Citalid Cyber Insurance Portfolio Optimization is a data-driven platform designed for insurers to manage cyber portfolio exposure and underwriting decisions. The platform centralizes portfolio and risk management into a single interface, providing visibility into critical risk areas and high-risk profiles. It classifies risks by frequency and intensity to support prioritization and trade-off decisions. Security recommendations are generated per risk profile, linking existing security controls to potential financial losses. This bridges the gap between an insured's defensive posture and estimated financial impact. The platform supports peer benchmarking by comparing risk profiles across companies using sectoral and geographic lenses. Investment ROI simulation functionality calculates the ratio between security investment value and associated risk reduction. For reinsurance strategy, the platform provides 360° portfolio analysis and supports catastrophe (CAT) scenario simulations to help calibrate coverage based on risk concentration pools. Results and data are exportable and can be integrated into BI or data visualization tools. An API is available for connecting the platform to an insurer's broader IT ecosystem to support large-scale portfolio management.
