  • Patent number: 11409887
    Abstract: Systems, methods, and computer media for mitigating cybersecurity vulnerabilities of systems are provided herein. A current cybersecurity maturity of a system can be determined based on maturity criteria. The maturity criteria can be ranked based on importance. Solution candidates for increasing the cybersecurity maturity of the system can be determined based on the ranking. The solution candidates specify cybersecurity levels for the maturity criteria. A present state value reflecting the current cybersecurity maturity of the system can be calculated. For the solution candidates, an implementation state value and a transition state value can be determined. The implementation state value represents implementation of the maturity levels of the solution candidate, and the transition state value represents a transition from the present state value to the implementation state value.
