Superasystem Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo, Representative Director: Ai Yoshida) will launch a Design Partner Program for "MukenVault," software that protects TLS private keys, API keys, and authentication information in memory during execution, starting July 1, 2026, limited to 50 companies. Under this program, MukenVault evaluation versions will be provided free of charge to cloud providers, SaaS providers, SIers, MSPs, SOCs, AI companies, research institutions, and others. Participants can verify in a near-production environment within their existing cloud and on-premises setups a new security domain that protects "secret information exposed after intrusion," which traditional countermeasures have not fully covered. In addition, Superasystem proposes "Runtime Secret Protection," a new concept for protecting secret information in memory during execution. ■ Key Points of This Release Product: MukenVault (Software for protecting secret information after intrusion) Proposed Concept: Runtime Secret Protection Format: Design Partner Program (Free Evaluation) Recruitment: Limited to 50 companies/organizations Period: July 1, 2026 - August 31, 2026 Target: Cloud providers / SaaS providers / SIers / MSPs / SOCs / AI companies / OEM partners / Universities and research institutions / OSS communities / Press and media Technology: Patent pending (Application No. 2025-241853 / PCT international application in progress) Recommended Verification Environment: Ubuntu 24.04 and 22.04 ■ AI Has Changed Attacks. Therefore, We Must Change How We Protect. Until now, cybersecurity has primarily focused on "preventing intrusions." However, with the widespread adoption of generative AI, internal exploration, acquisition of authentication information, and lateral movement after intrusion are rapidly being automated and accelerated. In some environments, privilege escalation and cross-system access can be achieved in a short period. Future security requires not only "not being
