For many years, S/MIME email certificates remained in the shadow of TLS certificates. Although they played a critical role in ensuring the confidentiality and integrity of electronic communication, their development was relatively slow, and validation processes were often perceived as archaic, manual, and difficult to scale. In 2025, however, this situation began to change noticeably.
In the face of dynamic digital transformation, where the Zero Trust model is becoming the new standard and machine identity (workload identity) is just as critical as user identity, a reliable Public Key Infrastructure (PKI) forms the absolute foundation of security. For large enterprises, the choice of the right PKI architecture between the traditional Enterprise […]
In 2026, the TLS/SSL certificate industry is introducing another major change related to the maximum certificate validity period. DigiCert, as one of the largest certificate authorities, has confirmed that from February 24, 2026, all new public TLS certificates will have a maximum validity of 199 days.
For the past decade, the development of network cryptography has progressed in an evolutionary manner. We updated OpenSSL libraries, replaced SHA-1 with SHA-256, increased RSA key lengths, but all of this remained within a familiar security model. In 2025, for the first time in more than 20 years, we are facing a change that is […]
