Public Services Network (PSN) & Future Networks for Government (FN4G)

Recently, GDS have announced their intention to decommission the PSN (Public Services Network) as early as 2023.  This is an ambitious target which affects all users of the PSN and anything or anyone connected to it. 

What is the PSN?

The Public Services Network (PSN) is a Pan-Governmental network of networks providing OFFICIAL services to Government Bodies, Agencies and Arms-Length organisations in order to share data and communications be it email or other some other method of getting data to and from people as needed. 

It sounds quite simple doesn’t it? Well in essence it is, however as you can imagine, there are thousands of organisations using it and hundreds of services provided over it – so moving away from the PSN is no easy task. 

Why is the PSN going?

Surprisingly, it’s not only about money, which is often the driver for these changes, it’s more about its suitability for the future. 

The PSN in various guises, has been around since 1997, was designed at a time when the internet was a lot “wilder” and communications electronically with various departments and organisations was not standardized or as secure as much as it is these days… it was no wonder that a single system for communication was a boon to everyone! 

Historically, this has been relatively expensive for those organisations that do not have the in house skills to complete or the funding to put in infrastructure. More importantly, in order to get on it (and to this day is still the case) you have to ensure a level of security, and data assurance with systems integrity

Today, where we have standardised secure ways of communication, much better and cost affective internet services and solutions which present a more effective way of working and ease of use – it was time for a re-think

Future Networks for Government

“The Future Networks for Government (FN4G) programme started in 2018 to help public sector organisations move to modern networking solutions and away from the legacy PSN.” 

“FN4G is focussed on the long-term future of networking for government” 

There’s no definitive right way to move off the PSN and consume services. We are still in the early days and there is a lot more information coming as to what and where services will go and how you will access them. 

The risk ownership is also a consideration. The core requirement of accessing the PSN is a Code of Connection (CoCo) and, as an organisationyou have to demonstrate you are compliant to be allowed onto the networkHowever the “assurance” provided by the PSN will no longer be in place – organisations and commercial providers will responsible for the security and integrity of systems communicating with others. 

Several organisations have already made the first steps and, in some cases, leapt onto providing services over the internet. What we do know, is that you will still need to provide the same level (or higher) assurances to those organisations you are connecting to. No matter how long the PSN has left, the overriding factor in all these cases will be the need to ensure that data is protected, risks managed and solutions are secure to these new services.
