Telia: Findings in 2023 Audit

The 2023 audit of Telia Company revealed that the TeliaSonera Root CA v1 certificate does not meet certain compliance criteria, specifically regarding the Key Usage extension and subject information. This issue has been recurring since a previous audit. Telia is transitioning to a new Root CA, Telia Root CA v2, which is expected to be included in major root programs by the end of 2023. A remediation plan is in place to gradually move subscribers to the new CA hierarchy, minimizing disruption. However, the transition will take time as customers need to upgrade their systems to support the new CA.
