Cybertrust Japan Halts Certificate Issuance After Missing Apple's New CA Approval Rule

Cybertrust Japan will pause SSL/TLS certificate issuance from September 15 after its root CA partner failed to secure Apple's newly required sign-off for an outside-run intermediate CA, forcing revocations while Apple and Google approval remains outstanding.

Cybertrust Japan Co.,Ltd. (TSE Growth: 4498) will suspend its SSL/TLS server certificate issuance service from September 15, 2026, after a procedural gap left a newly issued intermediate certificate authority without Apple's required sign-off.

The company said root CA SECOM Trust Systems issued a new intermediate CA certificate for Cybertrust's service, but on August 31 discovered the process had not met a rule Apple adopted on August 1, 2026: externally operated CAs must obtain Apple's approval before being issued a certificate. Because that approval was missing, the new intermediate CA and every SSL/TLS certificate it issued must be revoked.

Cybertrust has reverted to its prior intermediate CA to keep issuing certificates, but that fallback can only sign new certificates until September 14, 2026, one day before the scheduled suspension takes effect. SECOM Trust Systems is still pursuing both Apple's and Google's approval for the new intermediate CA and had not obtained it as of the September 10 disclosure.

While it waits, Cybertrust is reissuing affected certificates, contacting customers individually, and preparing to route issuance through a separate intermediate CA operated directly by SECOM Trust Systems as a stopgap. The company said it expects to incur customer-support and related costs but has not yet quantified the hit to earnings, and said it will disclose promptly if matters requiring disclosure arise during that ongoing review.
