200 day certificate lifecycle management

Certificate lifecycles are shrinking. Are you ready for the change?

A major change is already happening in digital security. From March 2026, TLS certificates now have a maximum validity of just 200 days. In 2027 that will reduce further, to just 100 days. That means more frequent renewals, tighter compliance demands – and the beginning of the end of manual cert management.

Why certificate management matters

Digital certificates are the cornerstone of modern cyber security. Yet how these certificates are managed is fundamentally changing; the maximum cert duration is now only 200 days.

Further reductions are already on the roadmap – to 100 days in 2027 and just 47 days by 2029 – as part of the industry’s move towards faster certificate lifecycles and stronger automation.

These changes will significantly impact IT resource management. Yet effective certificate management is critical, helping to: 

  • Prevent outages & unexpected service disruption
  • Mitigate security risks by maintaining proper encryption
  • Enhance visibility & control with a clear view of your entire cert  inventory
  • Enhanced crypto-agility for post-quantum readiness

How we help customers like you

We’ve got decades of experience installing. configuring and optimising advanced security solutions for private & public sector organisations with complex security & compliance needs.

C&C Group is a leading software manufacturer specialising in designing, developing, delivering, and hosting cloud-based software solutions. Their solutions are primarily used by UK critical infrastructure companies operating in the electricity, water, gas, and healthcare sectors. As a long-standing customer of FullProxy, C&C Group needed to carry out a vital F5 hardware refresh and Bourne series to rSeries migration in order to modernise their network infrastructure and ensure compliance within a regulatory framework. 
The Improvement Service team was using terminal-based vulnerability assessment tools, but they needed a more intuitive, user-friendly solution that could provide clear visualisation of security data while meeting the stringent security requirements of public service applications. They were looking for a tool that would streamline their vulnerability management process without sacrificing robust security analysis capabilities.
