A manual anonymous GET of https://api.bakuraku.layerx.jp/rest/v1/tenant/users on 2026-08-23 returned strict-transport-security: max-age=15552000; includeSubDomains alongside x-content-type-options: nosniff, x-frame-options: SAMEORIGIN and x-permitted-cross-domain-policies: none. HSTS is present on the API path, absent from the ALB's catch-all 404. domains: - domain: layerx.co.jp dnssec: false caa: [] spf: true dmarc: true dmarc_policy: none - domain: bakuraku.jp dnssec: false caa: [] spf: false dmarc: true dmarc_policy: none notes: - >- Neither layerx.co.jp nor bakuraku.jp publishes a CAA record or signs its zone with DNSSEC. bakuraku.jp has no SPF record; layerx.co.jp does. Both DMARC policies are p=none, i.e. monitoring only — nothing is quarantined or rejected on a failure. - >- api.bakuraku.layerx.jp negotiates TLS 1.2 while the two web hosts negotiate TLS 1.3; Bakuraku's own security page claims TLS 1.3 for communications, which holds for the product hosts but not for the API host as probed on 2026-08-23.
