Apple’s 45-Day Certificate Lifecycles: What Does This Mean for You?

The recent CA/Browser Forum meeting revealed significant changes to Apple’s certificate lifecycles, and they seem to be following Google’s lead. With a proposal to reduce TLS validity periods to just 45 days by 2027, this adjustment to Apple’s certificate lifecycles has sparked even more anxious discussion among IT professionals – yes, it’s frustrating, but it’s also important. 

 

Understanding Apple’s 45-Day Certificate Lifecycles: The New Timeline 

The proposal demonstrates a measured approach to implementing these changes, with Apple’s approach, lifecycles will reduce gradually over the course of the next three years. 

Our partner, AppViewX, looks at the breakdown in more detail. Read their blog here.

“The shift in Apple’s certificate lifecycles reflects a broader industry movement towards more nimble security practices. While you and your team may be naturally concerned about increased management overhead, this evolution aligns with security best practices that IT leaders need to embrace rather than avoid.” – Chris Templeton, CTO at FullProxy

 Security Benefits of Shorter Certificate Lifecycles 

Looking beyond immediate operational considerations, Apple’s certificate lifecycle changes deliver several key security advantages: 

  • More frequent cryptographic updates to combat emerging threats 
  • Reduced exposure window for compromised certificates 
  • Enhanced domain ownership verification 
  • Lower risk of unauthorised certificate usage 
  • Improved digital asset tracking 

 

Impact on UK Businesses and Public Sector

British businesses managing certificate estates will need to adapt to Apple’s certificate lifecycle changes. The new 45-day validity period introduces more frequent renewal requirements – at least eight times annually – but simultaneously creates an opportunity to modernise certificate management processes. 

The proposed 10-day Domain Control Validation re-use period, while more stringent, ensures consistent verification of domain ownership; a crucial security measure in today’s dynamic digital landscape. 

Preparing for Apple’s Certificate Lifecycles Changes: A Strategic Approach 

Embrace Automation 

View the new Apple’s certificate lifecycles as a catalyst for implementing automated certificate management. Modern automation solutions – like AppViewX – transform frequent renewals from a potential burden into a seamless background process. 

Strategic Certificate Audit 

Use this transition period to map your current certificate ecosystem, identify consolidation opportunities and remove legacy certificates where needed. 

Deploying Proactive Monitoring 

Implement solutions offering real-time certificate visibility, centralised management and complete and comprehensive audit trails. 

Update Security Framework 

Revise your certificate management policies to support an automated renewal process and establish clear responsibilities and incident response procedures. As well as this, it’s imperative that you align with the new industry standards across your whole estate.

The Future of Certificate Management 

While adapting to Apple’s certificate lifecycle changes may seem daunting, this shift reflects the growing importance of up-to-date certificates being a key factor for cyber security. Organisations that modernise their processes now will be better positioned to maintain robust security postures while managing certificates effectively. 

While these enforced changes doubtless present technical and operational challenges, the cyber security benefits of ever-shorter certificate lifecycles will continue to outweigh the difficulties. Certificate automation technology is the answer, removing the headache from these and future changes, while giving you full visibility and control of certificate lifecycles.

The debate has been raging for years. Which is the superior application delivery controller (ADC), F5 BIG-IP or Citrix NetScaler?
Certificate management has become a higher profile challenge recently thanks to Google’s well publicised intention to reduce certificate lifespans, acceptable for use in its popular browser Chrome, to a maximum of 90 days.
Now more than ever is the perfect time to reflect on the past and consider how we can enhance our cyber security practices using cyber security tools. With new threats emerging by the second, staying one step ahead of cyber threats is crucial. Within this blog, FullProxy will explore the best cyber security tools available in the market right now and provide insights on the steps you should take to refresh your network for a secure and resilient future.
