金融サービスと Fintech 向けの高度な API セキュリティソリューション

1. Low Cost-Benefit Ratio:
If you have already developed or are operating parts of the functionality yourself, or if you do not wish to hand over authentication information to a third-party provider like an IDaaS (Identity as a Service), it can be difficult to fully leverage the rich features offered by CIAM solutions. As a result, you may not receive benefits that justify the cost.
‍
‍2. Lack of Scalability:
Even if the need arises to enhance your CIAM infrastructure as your business grows, it can be difficult to extend beyond the specifications of an all-in-one solution. A typical example is adapting to advanced OAuth/OIDC requirements. Only a limited number of CIAM solutions can keep up with evolving specifications such as FAPI, mTLS, DPoP, PAR, RAR, and best practices like the OAuth 2.0 Security Best Current Practice.
‍
‍3. Lack of Control over User Touchpoints:
If you delegate “user authentication and consent confirmation” to an all-in-one CIAM solution, you lose control over customer touchpoints. This makes it difficult to continually improve and enhance the user experience. To evolve CIAM in line with changing business requirements and to increase customer satisfaction, it is crucial for service providers to retain control over their CIAM infrastructure.

By adopting Authlete, which operates entirely as a backend service, service providers can externalize only the technically challenging aspects—OAuth/OIDC protocol handling and token lifecycle management—without outsourcing the entire CIAM foundation. This allows them to freely design login screens, manage user profiles, and implement any user authentication, consent management, or access control mechanisms they choose.
