Will Upgrading to F5 rSeries Improve my Quantum Resilience?

When sufficiently powerful machines arrive, today’s encryption standards - RSA, ECC, and others - will be rendered obsolete. The UK’s National Cyber Security Centre (NCSC) has already set a 2028 milestone for all of us to complete cryptographic inventories and prepare for post-quantum migration. For many, one of the most strategic steps towards quantum resilience is already on the roadmap for F5 customers: upgrading from iSeries to rSeries.

Preparing for the Quantum Future: A Practical Guide to the NCSC Post-Quantum Cryptography (PQC) Roadmap

The threat posed by future quantum computers is no longer theoretical. When these machines arrive (or sooner) today’s encryption systems will be at risk, as quantum algorithms such as Shor’s could break widely used public-key schemes. Experts speak of a looming “Q-Day”, and the UK’s National Cyber Security Centre (NCSC) has set out a clear, phased PQC roadmap we should all act on now.

Why TLS Certificate Lifecycle Reduction Improves Security

The push for certificate lifecycle reduction stems from a fundamental truth: certificate lifecycle management is not a team member’s core job role – it's often an afterthought and annoyance, a general admin task. With these changes, this will fundamentally not be the case.

How to Prepare for the NCSC’s Post-Quantum Cryptography Migration Timelines

The arrival of post-quantum cryptography (PQC) is no longer a theoretical concern, it’s a strategic imperative for businesses across the globe. The UK’s National Cyber Security Centre (NCSC) recently issued updated guidance that underscores the urgency for all organisations, particularly those operating critical infrastructure or bespoke IT systems, to begin their migration to PQC today.

Untangling Multicloud Networking Complexity

With cloud services becoming increasingly easy to procure, software developers have flocked to them quickly for a range of reasons. Whether this is to unlock productivity, access on-demand innovation, or accelerate releases, the benefits of shifting to cloud networking are quite clear. After this, developers discovered the additional capabilities of another cloud provider and started using that one, too. This rapidly resulted in:

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.

TLS Certificate Automation to Enhance Cyber Security

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.
