SSL/TLS certificates are moving towards a 47-day lifecycle by 2028, following Apple's proposal in the CA/Browser Forum. This significant change from the current 398-day period aims to enhance security and promote automation in certificate management.

The proposal includes:

• Gradual reduction to 47-day maximum validity for SSL/TLS certificates
• Domain Control Validation (DCV) reuse period reduced to 10 days
• Implementation timeline extending to March 2028

Key benefits of shorter certificate lifecycles:

• Reduced vulnerability window for potential attacks
• Faster response to emerging security threats
• Forced adoption of automated certificate management
• Enhanced overall digital security posture

Impact on businesses:

• Increased frequency of certificate renewals
• Need for automated certificate management
• Greater emphasis on efficient monitoring systems
• Required modernization of existing infrastructure

While not yet mandatory, businesses should start preparing for this change by:

• Investing in automation solutions
• Updating certificate management practices
• Implementing monitoring systems
• Establishing automated renewal processes
• Training staff on new protocols

The transition to shorter certificate lifecycles reflects the industry's commitment to improved security standards and automated processes. Organizations that adapt early will be better positioned to maintain secure and reliable operations while meeting evolving compliance requirements.

Industry experts recommend starting preparations now, even though the change isn't immediate. This proactive approach ensures smooth adoption of new standards while maintaining robust security measures for business operations.

Remember: The key to success is automation. Manual certificate management will become impractical with 47-day lifecycles, making automated solutions essential for maintaining security and preventing service disruptions.
