ROI Calculation Logic

Automating key sharing evaluation and update tasks could reduce annual costs from ~$350K/year (AI est.) for 5 security specialists to ~$250K/year (AI est.), resulting in ~$100K/year (AI est.) in savings. Additionally, a 10% reduction in the annual probability of a cyber attack, with an average damage of ~$1.5M (AI est.), could avoid ~$150K/year (AI est.) in losses. This totals a potential annual cost reduction of ~$250K (AI est.) and mitigation of ~$1.5M (AI est.) in potential cyber risk per facility.

Speed to Market
4× faster than in-house development
Developing a similar system in-house would require at least 4 years and significant resources for defining attack models, building quantum/classical eavesdropping scoring logic, quantifying usability requirements, and developing an integrated selection algorithm. This technology, with its core algorithms and evaluation logic already established as patented IP, allows licensees to focus on integration and customization into existing systems, potentially shortening time-to-market by approximately 3 years.
