The reinsurer E+S Rückversicherung AG - in cooperation with Meyerthole Siems Kohlruss (MSK) - has developed a cyber tariff for small and medium-sized enterprises. The tariff is an important element in the range of services that E+S Rück offers its clients. After intense research, MSK has provided an actuarial basis for the calculation of this tariff - via an estimation of expected claims for a large number of individual service components - and documentation that meets the regulatory demands of risk management. Thanks to its modular structure, it is possible to develop - in close collabration with the primary insurer - a cyber tariff that takes account of the diverse and individual demands of the insurer, e.g. segments of target clients. Furthermore, a network of service providers for risk assessment, risk sensitizing, claims processing and forensics is made available when required.
