Why certificate management matters

Digital certificates are the cornerstone of modern cyber security. Yet how these certificates are managed is about to fundamentally change; from March of next year the maximum cert duration will effectively halve to just 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.

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.
A leading UK based wealth management platform provider with global reach approached us wanting to ensure the security of their customers’ encryption keys. Encryption being the process by which data is encoded so that information is only accessible by authorised users and even if someone was to gain access to it, they would not be able to read it.
