SSL Certificate Validity Period Shortening Countdown — Last Chance
Did you know? Let's Encrypt announced in June 2025 that it will gradually stop sending email notices for expiring SSL certificates. If you forget to manually renew a free certificate, your site could instantly be marked "Not Secure," leading to lost visitors, lower search rankings, and reduced brand trust.
Choosing a paid SSL certificate delivers higher-level OV/EV identity validation and typically includes reliable automated renewal reminders or services, comprehensive technical support, and stronger encryption (OV/EV). It also enables clearer browser security indicators to boost user trust. Don’t let a single oversight damage your website’s security or reputation—upgrade now for professional SSL services that provide stability, security, and peace of mind.
According to the latest certificate authority policies, certificate validity periods will be shortened across the board. Shorter maximum validity reduces the risk window if a certificate is compromised or stolen — attackers could use a compromised certificate to sign malicious content and bypass security products or Windows verification. Shorter validity lowers the long-term impact of a compromised certificate. Take advantage of our Black Friday offers — don’t miss out!
Frequently Asked Questions
Important Notes
- Event period: 2025/11/17 00:00 to 2025/11/30 23:59 (based on system transaction time). Promotional prices apply only to orders placed during the event period and payment must be completed within the specified deadline.
- Promotions apply only to the products and prices listed on the event page. Orders are finalized upon successful payment; electronic services are non-refundable after purchase.
- Multi-year SSL purchases made before the new policy takes effect will remain valid according to the original contract term and conditions and will not be affected by the new rules.
- After purchase, you may choose to activate the certificate immediately or reserve it for later domain binding.
- The certificate 'maximum activation period' is governed by CA/B Forum policies. Under current rules, domain validation (DV) data reuse is limited to a maximum of 398 days. Therefore, your purchased SSL/TLS certificate (e.g., Certum SSL DV) must be activated and issued within the maximum valid validation period after purchase to ensure certificate validity.
- The S/MIME certificate validity shortening policy and schedule differ from public-trusted SSL/TLS site certificates. Your purchased S/MIME certificate will retain the validity period chosen at the time of purchase.
- Applying for an S/MIME certificate requires email verification. Please ensure the email address you provide is valid and able to receive verification messages.
- Once a certificate is issued, its validity period begins and cannot be changed or extended to the previous longer validity period even if done before the new policy date.
- 'Automatic renewal' for paid SSL/TLS certificates generally refers to reminder and renewal services provided by us, not fully unattended renewal. Please follow your certificate management console and any notifications we send to ensure renewal is completed before expiry.
- Installation services are not included in the promotion. For paid installation or managed services, please contact customer support.
- YuanJhen Information reserves the right to change event terms and the final interpretation of the promotion.
